Cheap DRAMless SATA SSD does what's asked of it.
Bought this as a secondary storage drive for my laptop. The primary drive-which has the OS installed to it is a m.2 NVME, so this drive doesn't have to do very much. It's for music/videos/some Steam games. The NVME has Windows installed. The attached screenshots are speedtests while it's still quite empty-only about 130GB is in use here. The speedtests are quite good. Actually, when you consider the price they're great. Sequential speeds come close to saturating the SATA III bus which is nice. On the right, you'll see that the drives S.M.A.R.T statistics reported a nearly new drive-although it indicates it's been powered on 8 times which was strange..this was the first time I had powered the drive up after partitioning. On setup: This drive comes blank, obviously. It needs to be partitioned then formatted & assigned a drive letter so you can use it. My OS wasn't stored stored here-but if your using this as a boot drive, obviously you'll need to install Windows to it at this point. This is a GREAT drive for an older PC, or for secondary storage or use for extra games. The bad: This is a DRAMless SSD. So, when writing large large amounts of data to it for long periods of time it will slow a bit. This has no effect on read speeds though and unless your in video/music production your unlikely to even notice. It doesn't show in speed tests, it shows in extended operation during file copy for example (when the file is greater than 30GB+) But for $30? Pretty good.
