Someone who says the ST-251 sucks but the Kalok Octagon KL-320 is one of their favourites. That opinion might be as rare as the 'perfect' Kalok you showed earlier on!
This is the first generation of a series of drives which used Seagate's proprietary high performance low-inpedance steppers. The development of these advanced motors and a high amount of internal intelligence gave these drives an enormous performance edge, only to be outclassed by more expensive servo and rotary voice coil actuated drives. The peak of this technology's development was perhaps seen in their later IDE and SCSI versions which included what may have been the world's first intelligent silent stepper drive.
I've played around with one of these motors, out of a dead ST-157A in my case - they're interesting to spin by hand, they don't have the same feeling as more conventional steppers do when you turn them.
@@douro20 I wouldn't say these had a performance edge at all, let alone enormous. There were dozens of drives which matched these performance numbers, and often were more reliable. This drive is well liked because it was extremely low cost and made by a "reputable" manufacturer, meaning this got OEM'd into everything everywhere and is one of the most common trash drives you can still pick up to this day.

@@aprilkolwey4779 Yes, the detent effect is lesser.

man this thing screams for a stepper drive
@@thegeforce6625 What do you mean? It's about on par with most of the midrange drives of it's era.
Does MLC-2 mean the drive has more performance? I know it means manufacture line code but do they have better performance than the ST 251-1?
The figures attained here are better than the ST-251-1's specified 28ms random seek, but I don't know if that's within normal variance for it.
@@Kali_Krause I do not know. My testing has showed no appreciable difference between any of them.
@@longrunner258 I find the specs listed are almost universally wrong for every drive.
