Only reason to get a DRAM-less SSD (like this Kingston A400) is to use them as a temporary drive for gaming. Don't use them as your OS or storage drive.

Stutter is a common one - when at high loads.

Example; let's say I'm batch processing 500 images in photoshop, post process them with a filter. While doing that, if I try and open another process on say - premiere pro to put the photos that are done processing into a timeline, that's where the stutters will start. Then the system starts having freezes as the drive tries to read and write at the same time. This gets even worse when you start filling up the drive and there's even less space for the controller to write to the NAND.

On an NVME drive or even say an "entry-level" drive with DRAM (i.e MX500 or 850/860 Evo) - none of this issue happens. Of course the NVME drive will be quite a bit faster during heavy loads but the important thing is, stuttering or fingers crossed - entire system BSOD is rarely (if ever) going to happen).

Now I do have several A400 480gb drives that I use just for Steam storage and external storage for the PS4 Pro. In those cases, they work FINE. That's because the loads on the drive is minimal as game loading rarely ever exceeds half the drive's capable read and IOPS speed, much less to say saturate it. Since seek time and latency difference is fairly negligible between the cheapest SSDs and highest end, game load times aren't a very significant difference.

Well I have 24 office PCs using Sandisk SSD+ 240GB as their main drive too - but all those PCs do are only documents, web surfing and what not but they save all their work on a server or on a local mechanical HDD. But if we're talking about high level, extensive loads here, I would not install those SSDs at all even if my account side wants to save just a couple thousand dollars - I'd rather pay from my own pocket to install 860 Evos at the very least.


Same shit different flavor. Using the same controller (Phison S11), using the same NAND type. If you're going to get budget SSDs, just get the cheapest one.
