Same thing. I was confused with Newegg having an "M.2 PCIe" section AND an "M.2 Sata" connection. None of the "big guys" covered that shit in their videos, so props to this guy.
9:50 Thank you for not cutting this and re-recording it. A lot of RUclips channels will scrap clips like this, but in your video it offered a nice pause in the flow of information, gives a chance to reflect on what each of the terms mean. It also helps to know that even the pros sometimes mix this up, that we're not all stupid because we have to look it up. Great video!
Thanks for watching! There is a LOT of terminology to get right here. I usually try to keep it real, and yes, I do sometimes mess up because it is quite complicated.
Thank you so much for this video. After buying a second NVME drive, installing it, not having it recognized, and then reading it wouldn't work in my motherboard but not fully knowing why it wouldn't work was driving me crazy. This was so simple and clear and now I understand my second m.2 is only sata and not nvme compatible and it all makes sense now.
I've been chugging along with my early 2010 CPU (Intel i7-2600K) in a machine where the CPU is the ONLY orig part from the original computer it came from (on powerspec from Microcenter). I recently decided to "upgrade" to a HP 840Z that comes with X2 CPU's and 126gb of ram, etc.. Typical beefed up HP. Though it comes with 5 SSD's (all 1 tb), I plan on picking up a card and NVMe 1 or 2 tb drive as my boot drive and migrate the 26tb's (two 8's and one 10tb drive) to the new PC. This video sheds some light on what and how these will turn my new beast into a demon. Thanks
I haven't seen any other explanation about this subject as good as yours... I was totally confused, and mostly because some sellers don't help very much with the description of their products, specially when they lack consistency... it makes me think some times that is a total different product, and sometimes that is the same, but it isn't... Thank you very much for such good explanation.
Just put together a new gaming PC for Christmas. Took advantage of the Black Friday sales. This always seems to be the best time of the year for deals on closeouts. The newest models are coming to market and computer warehouses are trying to get rid of the older models which usually perform quite well.RUclips videos like these are really essential to understanding if you are buying the best performing components for the best price. I think I did pretty good this year! Bought a 2TB M.2 NVME PCIe 3.0 x 4. My understanding is the prices will continue to drop dramatically. I plan to switching totally to SSD drives by this time next year. Thanks for this video. Really helpful!
It's truly nice that you have explained this for us . Especially in a much clearer fashion. I do have the Nvme.2 or should I say more like a stick of gum. I love it keep up the good work. Keith
Thank you kind sir! Your video is very pleasant to watch and as a Latino I love your outro! I was looking for the best hard drive for my first build and you helped me pick one. I bought a new x570 tomahawk, a new 011D PCMR, Corsair Vengeance pro 16GBX2 (3200Mhz) and you inspired me to get the Samsung 970 PRO M.2 PCIe Gen3 X4 (that was a mouthfull). I'm so excited for my first build but Im leaving the best for last...the Zen3. UPDATE: Im returning my Tomahawk X570 because its 1 and a half inch smaller than the average motherboard and it looks funny to me in my 011D PCMR which is basically an XL.
Thank you sir for the clear and informative video. Most videos on this topic on RUclips are quite click-baity and don't provide nearly as much information. I subscribed.
Excellent narration. One of the very few presenters who understands how to 'Speak' .. Yes, there is a difference between Talking and Speaking. Many inexperienced and untrained presenters have a rapid cadence. as if they are in a hurry to get to the 'Toilette' yapping like baring dogs it does not give time for listener to absorb and enjoy what is being said. Presenting and eating are in effect the same. Go slow and enjoy the content., be it words of a meal. So top marks Home Tech Adventure. Thumbs up for your presentation. It so happens that my SATA III interface card has provision to install an M.2 Drive, which I am expecting to purchase, having 1 TB capacity to replace a KINGSTON 240GB SSD. The SATA III interface card also has a USB C socket, which I find useful when I need to connect my Cell phone for Data exchange or even Battery Charging.
Finally a good Explanation on this topic. Thank You very much. So it is just a Matter of time before the 2,5" SSD'S are going to dissapair in the newer Laptops, desktops?
So confusing...But I did manage to buy an M.2 NVME PCie memory. What a change! 5 minutes or more boot time and now in 20 seconds or less. Well worth the investment. I wish I saw this channel earlier though. Thanks!
Thank you so much ,,, really upto this point I always thought that all SSD were the same .Very detailed explanation ,,, looking forward to seeing more on this channel
Thanks for the idea! I do have an old Intel B85 motherboard and processor that does not have an an M.2 slot that would be great for testing this. I will consider this for one of my future videos.
M key, B key, M+B Key, M Key SATA, B Key SATA and M+B Key SATA. With all the pre-built companies putting in cheaper M+B SATA drives it's nice to know what you pulled out of a machine if you decide to slap it in a PCIe adapter for say, a DIY NAS. Lots of laptops come with a 128gb M.2 SATA drive and it still huge for a boot drive on a home built NAS.
I have an ASUS Prime B550 Plus motherboard. Which drive would work faster with this motherboard. M.2 or NVMe PCIe ? It currently has an M.2 . I built it myself (first time) before seeing this video and was wondering which one would work better or if my motherboard actually supported NVMe PCIe. Loved your video. Great job. :)
Thanks for a great video, I’ve watched many and not learned nearly as much as I have with yours. I Just bought a Qwiizlab UH25 Pro for my new MAC Mini M2, this is all new territory for me. Hope you don’t mind my newbie questions; Are the two internal ports (the M.2 SSD & the 2.5 inch HDD), here for increasing capacity ? Can I install just one or the other ? Or do I have to install both ? Would the UH25 run a SATA III ? Should the two drives be the same protocol ? Is this similar to the old PC configuration of a large hard drive that was typically partitioned into a boot drive and multiple storage drives ?
The two internal ports are to increase your Mac Mini's storage capacity. You can install just one or the other in this unit. You can install any combination of drives. Since it looks like the M.2 slot only accepts NVMe Gen 3.0x1 units, I would just get a 2.5" SATA drive. The SATA drive slow would be running the SATA III protocol. I don't think you would see much difference in performance and it might be less expensive to go with a 2.5" SATA drive. This would be similar to a PC with a large hard drive. You will need to use Disk Utility on the Mac to format the drive after it is connected. The boot drive will be internal to the Mac Mini and the other drives will be extra storage drives.
THANK YOU! You have answered my question at 1:10 already, why does no one else make tell you this haha. I'm still going to watch the rest of the video to learn more. SUBBED.

Man I just started to upgrade my ssd (mostly to increase storage not necessarily power) and learn about it all. Turns out according to your list, i bought the lowest standard m.2 sata ssd. However, it is what my laptop can take anyways, no nvme ever for this device. But I can't complain, because it's the fastest device I ever had and works well for what I need it for anyways.
Thanks for watching! I am responding to you on a computer with a M.2 SATA SSD. Fast enough for this use. You won't see much of a speed difference with normal use cases.
So if I understand correctly, M.2 describes the PHYSICAL connection between two devices (e.g., the SSD and the motherboard) and NVME describes the protocol, that is, how the two devices communicate to transfer data? I am going to build a PC for the first time, and I'm considering a motherboard that has (among other things) the following storage interface specs: "1 x M.2 connector (Socket 3, M key, type 2242/2260/2280/22110 SATA and PCIe 4.0 x4/x2 SSD support)". Here's what I understand of the various terms, based on your video and Wikipedia: M.2 connector - describes the physical connection Socket 3 - describes sockets keyed for four PCI Express lanes, which determines data transfer speeds M key - describes the mating key positions/notch, which determines the type of modules accepted by the motherboard. According to Wikipedia, "M.2 modules with only one notch in the M position use up to four PCI Express lanes," so do "M key" and "Socket 3" provide the same information since both describe M.2 devices that have four PCI Express lanes? type 2242....22110 - describes the width and length of the m.2 connector. Many lengths are accepted by this particular motherboard. SATA SSD support - can use SSDs that use SATA, an alternative--slower--protocol (way of communicating) compared to PCIe PCIe 4.0 x4/x2 SSD support - can use SSDs that use PCIe 4.0, the latest version of the PCIe protocol with the highest transfer speeds. Furthermore, the SSD may use either two or four PCIe 4.0 lanes. Any corrections you would make to my description?
The PCIe 4.0 is backwards compatible with PCIe 3.0, so you could use a PCIe 3.0 M.2 SSD to save money. The difference in speed would probably not be noticeable unless you transfer large data sets a lot.
I have quite old but really good platform ASUS P9X79 with Intel Xeon E5-2697 v2 and 4x4GB RAM Quad Channel G.SKILL memory. Now I do have SATA 6GBs connections on motherboard and I do have four PCIe 3.0 16x slots (3 are empty). There is also PCIe 2.0 1x which is no use to me. What do you suggest. Stay with SATA 6Gbs or buy some kind of controller PCIe 3.0 x16 for M.2 PCIe NVMe drives?
"G1.Sniper B6 * Support for M.2 PCIe SSDs only." Does it mean that my MB can only support M.2 NVMe? I just bought an M.2 SATA and it does not show up on my disk manager
Question im replacing the drive in my dell G7 laptop... i brought the samsung 980 pro PCIe 4.0 NVMe M.2 1TB however the drive that im replaceing I notice is a SATA 128 gb drive that shaped the same but has 2 spaceings.. does this means the M.2 that fits into the slot and it has one space at the pins... will not work. With my mashine. Dell company said it was the drive to purchase... Im thinking now that I have a SATA slot on my computer.... but Dell just wanted me to purchase the drive that cost the most.. should I take the 970 pro back or will it give me some power/speed...
I have a crucial M2 SATA, now I'm upgrading to another laptop which is using PCI gen3x4 ports with a M2 nvme already inserted. Can I add the M2 SATA to the other slot or it won't work at all?
Questions: What use cases benefit from a depth of Q32? (Am I right in understanding this as depth of the pipeline or queue?) Will this increase performance for media creators moving around big files? Why do bigger SSDs outperform smaller SSDs? You gave the example of 1 TB vs 500 GB. On old spinning disk technology, this was generally true because a a smaller disk was more “filled” (assuming the same amount of storage used) than the larger, resulting in longer seek times. (This is also why defragging your hard drive was a thing, iirc). I didn’t think that SSDs had this issue, but maybe I was wrong. I also watched a LTT video a while back that was comparing super cheap no-name M.2 SATA storage with M.2 SATA from name brand companies. The cheap one (I believe the brand was “Golden Pigeon”) performed terribly; the reason given was that it was using a single chip vs the more expensive name brand using multiple chips (each storing a smaller amount). Is this related to my second above? Thanks for this video. It clarified a lot of the confusing information I’ve already seen.
Q32 and beyond are important for server workloads, where many users use the same storage device at the same time. Think of an office server with a database that everyone needs to access regularly. Moving a big file is just one request, so assuming you don't try to do other work at the same time, Q1 performance may be best. However, writing to the NAND memory in an SSD is SLOW, so manufacturers of quality SSD's include a RAM buffer to catch some large transfers and then write it to the NAND memory during idle times. If the file transfer is too large for the RAM buffer to handle, then the SSD can slow way down. Depending on the SSD implementation, this can slow down below the speed of a good hard disk for very large transfers. Better quality SSD's have faster NAND and can keep up better. Bigger SSD's tend to have multiple smaller NAND chips to create the larger size. The SSD controller can use this to an advantage by writing to multiple NAND chips at the same time from the RAM buffer resulting in faster speeds; more parallel operations means more speed. A few of the smaller SSD's are now being designed with more smaller NAND chips to keep the speed competitive with larger SSD's. Also, some very cheap SSD's have smaller or even no RAM buffer which really slows down large file transfers. Unless you spend $$$$$ on a super fast SSD, a hard disk may be more cost effective if you transfer very large files regularly. Also, if it is really important to transfer very large files quickly, certain types of RAID setups will really improve performance. This is again a form of parallel operations, this time spread across multiple hard disks or SSD's.
Hello dear, Thank you for the details, you explained everything very nicely. i want to by Lexar nm500 which nvme pcei 3.0x2 with b&m key slot, mean 2 notches. do you thing its ok for regular pc use, photoshop, premiere pro and gaming? Thanks in advance.
After watching a few videos, this is the only video that answers all my questions about m.2 thing. Thanks a lot sir
Same thing. I was confused with Newegg having an "M.2 PCIe" section AND an "M.2 Sata" connection. None of the "big guys" covered that shit in their videos, so props to this guy.
Same here..
You are most welcome
OuTSMoKE or if they do cover it, they take forever to get to it, and there’s a lot of useless information.
Academic level explanation of SSD types. Thanks for upload.

By far one of the best videos on RUclips to understand M.2 shenanigans !
the only helpful video i could find that simply and thoroughly explains the subject of m.2 storage. thank you so much!
So glad!
as said below
your the first person to explain in depth
Good work sir
no one in youtube shows and explain like this thank you

Thanks for the compliment.
So I can't use a M.2 AHCI SSD on a M.2 NVMe slot on my motherboard? Thanks for answering and God bless
You may be able to, it depends on your motherboard. Check the specs on the manufacturer's website.
Thanks for this video.
You bet!
Hi. Will an M.2 NVMe PCIe SSD perform the same speed if it is installed to the PC with an adapter board via PCIe express slot...?

Amazing tutorial! Very helpful!
Glad to hear that!
Very informative. Subscribed
Welcome aboard!
Good explanation. thanks!
Thanks for watching!
hey man i loved the video hope you are well god bless
Thanks, you too!
All info. Thanks!
No problem!
Man I just started to upgrade my ssd (mostly to increase storage not necessarily power) and learn about it all. Turns out according to your list, i bought the lowest standard m.2 sata ssd. However, it is what my laptop can take anyways, no nvme ever for this device. But I can't complain, because it's the fastest device I ever had and works well for what I need it for anyways.
Thanks for watching! I am responding to you on a computer with a M.2 SATA SSD. Fast enough for this use. You won't see much of a speed difference with normal use cases.
So if I understand correctly, M.2 describes the PHYSICAL connection between two devices (e.g., the SSD and the motherboard) and NVME describes the protocol, that is, how the two devices communicate to transfer data?
I am going to build a PC for the first time, and I'm considering a motherboard that has (among other things) the following storage interface specs: "1 x M.2 connector (Socket 3, M key, type 2242/2260/2280/22110 SATA and PCIe 4.0 x4/x2 SSD support)".
Here's what I understand of the various terms, based on your video and Wikipedia:
M.2 connector - describes the physical connection
Socket 3 - describes sockets keyed for four PCI Express lanes, which determines data transfer speeds
M key - describes the mating key positions/notch, which determines the type of modules accepted by the motherboard. According to Wikipedia, "M.2 modules with only one notch in the M position use up to four PCI Express lanes," so do "M key" and "Socket 3" provide the same information since both describe M.2 devices that have four PCI Express lanes?
type 2242....22110 - describes the width and length of the m.2 connector. Many lengths are accepted by this particular motherboard.
SATA SSD support - can use SSDs that use SATA, an alternative--slower--protocol (way of communicating) compared to PCIe
PCIe 4.0 x4/x2 SSD support - can use SSDs that use PCIe 4.0, the latest version of the PCIe protocol with the highest transfer speeds. Furthermore, the SSD may use either two or four PCIe 4.0 lanes.
Any corrections you would make to my description?
The PCIe 4.0 is backwards compatible with PCIe 3.0, so you could use a PCIe 3.0 M.2 SSD to save money. The difference in speed would probably not be noticeable unless you transfer large data sets a lot.
I have quite old but really good platform ASUS P9X79 with Intel Xeon E5-2697 v2 and 4x4GB RAM Quad Channel G.SKILL memory. Now I do have SATA 6GBs connections on motherboard and I do have four PCIe 3.0 16x slots (3 are empty). There is also PCIe 2.0 1x which is no use to me. What do you suggest. Stay with SATA 6Gbs or buy some kind of controller PCIe 3.0 x16 for M.2 PCIe NVMe drives?
Informative - SUBSCRIBED!!
Awesome, thank you!
"G1.Sniper B6 * Support for M.2 PCIe SSDs only."
Does it mean that my MB can only support M.2 NVMe?
I just bought an M.2 SATA and it does not show up on my disk manager
How much difference is there between 512GB PCIe M.2 Class 40 SSD & 512GB PCIe NVMe M.2 🤔
Question im replacing the drive in my dell G7 laptop... i brought the samsung 980 pro PCIe 4.0 NVMe M.2 1TB however the drive that im replaceing I notice is a SATA 128 gb drive that shaped the same but has 2 spaceings.. does this means the M.2 that fits into the slot and it has one space at the pins... will not work. With my mashine. Dell company said it was the drive to purchase...
Im thinking now that I have a SATA slot on my computer.... but Dell just wanted me to purchase the drive that cost the most.. should I take the 970 pro back or will it give me some power/speed...
Very well presented
Glad you think so!
Excellent video
Thank you very much!
I have a crucial M2 SATA, now I'm upgrading to another laptop which is using PCI gen3x4 ports with a M2 nvme already inserted. Can I add the M2 SATA to the other slot or it won't work at all?
Questions:
What use cases benefit from a depth of Q32? (Am I right in understanding this as depth of the pipeline or queue?) Will this increase performance for media creators moving around big files?
Why do bigger SSDs outperform smaller SSDs? You gave the example of 1 TB vs 500 GB. On old spinning disk technology, this was generally true because a a smaller disk was more “filled” (assuming the same amount of storage used) than the larger, resulting in longer seek times. (This is also why defragging your hard drive was a thing, iirc). I didn’t think that SSDs had this issue, but maybe I was wrong.
I also watched a LTT video a while back that was comparing super cheap no-name M.2 SATA storage with M.2 SATA from name brand companies. The cheap one (I believe the brand was “Golden Pigeon”) performed terribly; the reason given was that it was using a single chip vs the more expensive name brand using multiple chips (each storing a smaller amount). Is this related to my second above?
Thanks for this video. It clarified a lot of the confusing information I’ve already seen.
Q32 and beyond are important for server workloads, where many users use the same storage device at the same time. Think of an office server with a database that everyone needs to access regularly. Moving a big file is just one request, so assuming you don't try to do other work at the same time, Q1 performance may be best. However, writing to the NAND memory in an SSD is SLOW, so manufacturers of quality SSD's include a RAM buffer to catch some large transfers and then write it to the NAND memory during idle times. If the file transfer is too large for the RAM buffer to handle, then the SSD can slow way down. Depending on the SSD implementation, this can slow down below the speed of a good hard disk for very large transfers. Better quality SSD's have faster NAND and can keep up better.
Bigger SSD's tend to have multiple smaller NAND chips to create the larger size. The SSD controller can use this to an advantage by writing to multiple NAND chips at the same time from the RAM buffer resulting in faster speeds; more parallel operations means more speed. A few of the smaller SSD's are now being designed with more smaller NAND chips to keep the speed competitive with larger SSD's. Also, some very cheap SSD's have smaller or even no RAM buffer which really slows down large file transfers. Unless you spend $$$$$ on a super fast SSD, a hard disk may be more cost effective if you transfer very large files regularly. Also, if it is really important to transfer very large files quickly, certain types of RAID setups will really improve performance. This is again a form of parallel operations, this time spread across multiple hard disks or SSD's.
Hello dear, Thank you for the details, you explained everything very nicely. i want to by Lexar nm500 which nvme pcei 3.0x2 with b&m key slot, mean 2 notches. do you thing its ok for regular pc use, photoshop, premiere pro and gaming? Thanks in advance.
It should work fine for that use.
