I have owned this Transcend 256GB MLC SATA III 6Gb/s 2.5" Solid State Drive 370 since November 2015 and it works perfectly. The time it takes to boot up my PC has been slashed. It now takes seconds not minutes. I didn't realize how much time I was wasting waiting for Windows to boot up every time I turned on my computer. I put my large programs on it and they come up in seconds. This has worked flawlessly with heavy use for over six months and I am confident it will continue to operate as it should. I actually paid more for it than it is at this writing but I still think it was a good deal. It does the job I intended it to do with no hiccups whatsoever.
