Transcend 512GB MTS220S NVMe PCIe Gen3 x4 M.2 2280 Internal Solid State Drive 3D TLC NAND with DRAM Cache -TS512GMTE220S

Bought 2, both faulty in under a month.

This was great value storage space and a massive upgrade on what I had before, but it's a fair bit slower than advertised...

Installed as a boot drive in an AMD 5600h based laptop. HWinfo reported that the drive had 99% life left even though the laptop started booting intermittently after 7 months of use. The laptop would crash randomly and after another 5 months stopped booting at all. I reformatted the drive, installed windows again and the problem remained. Re-installing the original 500mb nvme drive that came with the laptop resolved all issues. The drive never reached more than 80 degrees in the laptop according to diagnostics so I presume it just failed.

Got two of these on Prime Day and both of them can be ridiculously slow to read from, but when I run crystal disk benchmark, sequential reads show a good speed > 3000MB/s but when I play a game or copy files from them it's more like 30MBs, it's so slow games load with textures missing (Baldur's Gate 3 and Forza for example), moved the games (slowly) to a Western Digital SN850X (which is my boot drive) and everything instantly loadsI've made sure trim is running etc, and installed Transcend's SSDScope softwareApart from the WD SN850X, I'd always gone Samsung with previous drives for me and my family, and never had any problems, lesson learntUPDATE: basically the benchmark is quick because it writes data that ends up in the DRAM cache, which then reads nice and quick at expected speeds, but if you switch off the cache or benchmark with a file bigger than the cache it is 20-30MB/s again

Got it for £60 for a black Friday deal. 2TB with dram Cache would have been a steel but it was too good to be true.Starred failing after a while. Doing any sort of intensive task such as transfers large files or heavy gaming would cause the speed to slow down immensely.Windows was also installed on this drive so I had to deal with constant issues with booting as the ssd was failing.Having to unexpectedly buy a whole new ssd and transfer everything off a failing one was a missive pain.Never taking risks with storage again. I personally recommend brands like Samsung or crucial. Much more reliable in my experience.Though it's entirely possible I just got the one in a million defective. I doubt it though.

Used to upgrade a HP laptop, works a treat

Superb little NVMe for my laptop.
