The SN770 is great for people who only have gen 3 PCI express as it allows them to completely max out the interface with it's backwards compatibility. Most drives designed for gen 3 do not exceed 2000MB/s and are highly inconsistent when doing mass transfers, some of which drop down to 50MB/s. The only other drive that comes close is the Samsung 980 and even that doesn't max out. She gets pretty hot on sensor 2 though, so you'll want a heatsink.
Its trash. Transcend 220S kills it. Instead of dedicated RAM it uses own NAND as buffer. So SN770 has x0.8 factor of TBW/total size, where 220S has x2.0! At same price.
@@birdieblue19 I bought MTE220S for similar money and its much better, because it has dram cache, which gives it 4x more write cycles compared to wd. WD is actually trash.
Thank you for a genuinely good deep dive reviews. Short reviews have their place, but this is thorough analysis and review that was GENUINELY useful for me. I actually watched it twice.
@NASCompares So you say the SN770 suffers a drop in sustained writes after a while. Are you saying the SN850 does not (as with all DRAM SSDs)? I put it to you that the Host Memory Buffer has nothing/little to do with the large drop in sequential write speed. It's when the cache is used up.
All of them drops. Question is why will you need sustained write of large files? This product designed for average gamer / home user who will rarely need big stuff written. Unless you're planing to use it in a server or a work station these extreme tests are pretty meaningless.
I think it only happens around 330 GB. I don’t know many people constantly transferring over 300GB over and over. Most people transfer their data and just use it. Plus I think it clears around 30 GB a minute after that. So if you plan on going over 330 GB every single day it might add a few minutes to your transfer speeds, but idk who is doing that all the time.
Thank you for the review. The lack of DRAM is always something to considered in the back of your mind. SN770 only just available in Australian market, the price is very high, the 1TB SN850 is only less than AUD $10 more expensive in one retailer, so a no-brainer to choose the SN850 over the SN770. I am interested in your upcoming comparison with the Seagate Firecuda 520 because that's the new SSD I just bought.
Thanks for your great videos! I watched both this one and the one comparing the 770 and the 850. What strikes me is when you touched on the apparent greater efficiency and cooler operation. My usage scenario is as a light-moderate computing/OS drive in what is basically a thin Ultrabook (Samsung Book Pro 360). No gaming. So I'm considering battery draw and cooler running in addition to performance. This is one concern I have regarding the SN850 or Samsung 980Pro. Do you think I need to worry about this? Otherwise the difference in price is such that I'd just grab the SN850.
WD will publish the figures for both devices. but it is not easy to compare as in one case (SN770) the hosts RAM is utilised. But for the SN850 the on device RAM is used. So you need to include both parts if you want to compare. The only simple way to do so would be to have 2 identical test setups with one drive in each and see which lasts the longest. Having said that, I suspect the screen will be a big draw. So any small difference between the 2 SSD's is likely not important.
RAM isn't fingers in your term, RAM is capacitor, temporary storage, thing that smooths the flow. In CPU RAM is also used to offload the internal pockets (registers), aka execution stack!
Lower down the range, I recently bought a DRAM-LESS WD Blue SN570 2TB. What a disappointment! Using my Beelink Mini S Windows 11 PC, with the drive in two different USB enclosures, it will NOT work! The drives appears and disappears. However, it seems to work on Windows 10. Is this some weird compatibility issue? Is the SSD faulty? Is it HMB? Although new to SSDs, I've built PCs for decades, but it's got me beat? All my other SATA SSDs work fine! Incidentally, the SSD cost £81.48, and was fully refunded by eBay, and I got to keep the SSD (although I'm unsure as to whether it's faulty or incompatible?). EDIT: Why price in dollars, when you're based in the UK?
Yeah but will it really hurt anything putting this in my PS5? My girlfriend bought me this for my birthday and I'd really like to use it. The only side effect I'm hearing is that games don't load as fast but they still play? So what's the big deal?
All the mixed results and reviews on the SN770 scares me. I decided to cancel my order and get the SN850 for peace of mind. Sure, it's $35 USD more, but it's worth it in the long run I think.
For gaming more than enough. These extreme tests are valid if you're planing to use it in a server or a workstation. Games once installed they only read data, rarely write stuff.
Hi I just purchased this ssd to replace my failed Samsung pm981a 1tb that came in my acer predator helios 300 was it a good idea or should I exchange it for a better one
@@gangar99 At least the fan on my mini-PC was not sufficient (Minisforum um790 Pro). Clearly requires a bigger fan and a heat sink with the SN770. The idle temp of the SSD was 56 C and it got up to 80 C quite easily. It heated up the processor and RAM sticks along with it. The CPU idle temp was 44 C and easily got close to 80 C. Now the PC has a new SSD with an idle temp of 38 C. The CPU idle temp is around 35 C and only under heavy load can rise to a little over 70 C. Quite a big difference.
I just wish you would have used HWInfo for monitoring the Temperature. There is a Sensor called "Temperature 2" for the SSD which is much higher compared to the Temperature you considered in the Test.
There are 2 one for nand and one for the controller. CrystalDisk info shows the controller I believe and HWinfo show both, Drive temp and temp 3 are controller with Drive temp 2 as nand. I am sitting at 37C for controller and 55C for nand. Runs hot when doing benches.
Hi is it good enough to put in laptop for a second m.2 and is it good enough to use for my iTunes music and movie and TV shows and audiobooks and podcasts my stuff is 1.2tb
i was really afraid that my system wont be able to cope with the SSD because my system doesnt support HMB. But at the same time, it also only supports PCI Gen 3. I am certainly not getting the absolute most out of the SSD but for my basic workloads (mostly involving browsing the internet and playing a game or two) this SSD is perfect. Now it dropped in price to about 40€ for a Terrabyte here in germany and it was a no brainer. I always had inconsistancy inssues with cheap small SSD's in the past because i always cheaped out to some absolutely unknown brand. For me, now i finally know what an SSD is suppose to feel like, and that for 40€ so i aint complaining
According to most of the benchmarks I’ve seen on the sn770, it is a great drive for both extra storage and a boot drive. Even though it doesn’t have dram, new versions of NVME added the ability for these newer DRAM-less drives to partition a small amount of system memory, which makes them a lot faster than they used to be. If you have less than 8gb of ram, then using it as an extra drive would probably still be fine, but you’d want a little more ram to use it as an OS drive to make sure there’s enough system memory to go around.
Thanks lot of help.So NVMe = no on board memory buffer for this SSD. also want to use it in a Asus Maximus Hero VII as a os drive for win 10 21H2. Intel i5 6600K @ 4.1ghz to 4.5ghz with 32gb DDR 4 memory. I do play WOW not daily. Can i allocate an amount of my DDR4 to it? any comments on this would help.
No your DDR4 RAM(random access memory) is used for the tasks you are doing in the moment. Its like short term memory for your computer. As soon as you close a program it goes off of the RAM and back into the storage for long term storage

why are the total reads and writes (in excess of 27 TB) so high before the tests?
Just picked up the 2TB for $120!
I still have it no issues
Great in-depth review! Thank you.
sorry im still confused is this good for gaming? like pubg, modded skyrim etc and booting pc? technoob here
For gaming more than enough. These extreme tests are valid if you're planing to use it in a server or a workstation. Games once installed they only read data, rarely write stuff.
Why would you buy a 2.5 SSD over a M.2 when M.2 are cheaper and faster?

@@scope-me2604 yes I decided to buy this, thank you so much :))

Does the 2TB version have chips on both sides of the ssd?
@@adonespitogonaif nope, it also has chips only on one side
How is it good or bad?
@@tph1232 It's quite good. I use it to store games, not as instensive as an SO drive, and for now 0 problems

So more RAM is needed for this SSD ?
Hi is it good enough to put in laptop for a second m.2 and is it good enough to use for my iTunes music and movie and TV shows and audiobooks and podcasts my stuff is 1.2tb
would it be okay to use this in something like an Acasis Thunderbolt 3/4 enclosure in order to do photo and video editing?
I would recommend it tbh, as you will be a reasonable write heavy scenario there. Pay the pinch extra and get the DRAM Pro version
