Review on Adata XPG SX8200 Pro 1TB NVMe SSD with 3D NAND, Gen3x4 PCIe M.2 2280, R/W 3500/3000MB/s (ASX8200PNP-1TT-C) by Elijah Balzarini

Can't recommend. I picked the 500GB version based on good reviews from Tom's Hardware, PC World, and a few other sites. The chip's overall benchmarks match the website's specs, showing 3000Mbps+ reads and 2200Mbps+ writes - note that they always show maximum write speeds based on a 1TB drive (over 3000Mbps) specify, and in fact it's difficult to find smaller drive specs on the manufacturer's site. . PC World claims that it can even match and outperform the Samsung 970 Pro in many tests. Well unfortunately synthetic tests are just tests and you should take them with a grain of salt. 1) At least Samsung now shows drive performance when TLC cache runs out on EVO and EVO Plus. Expect write speeds of up to 900Mbps for Samsung EVO 500GB drives when transferring large files. As for XPG, I can't find this information on their website, but after some of my own transfers of a single 8GB file to this drive, the speed usually drops between 400Mbps and 600Mbps within seconds and fluctuates around that range, although it sometimes hits 900Mbps for very brief periods. This is far from the specs of the 500GB versions and we'll be below the capabilities of my existing and older/smaller PCIe NVME drives. You can see that these speeds are based on my hardware or the file I'm transferring, but why do older drives still work better on my system under the same conditions and closer to the advertised speeds? My old 256GB Samsung 950 Pro still beats it with a solid 900Mbps when writing the same file, and my other first gen 500GB MyDigital BPX is also showing 900Mbps when writing with the same file tests. I also have 3 drives swapped so they each copy test files into the onboard m.2 slot, and 2 different PCI adapters into the 16 lane and 8 lane slots. While Samsung and BPX are relatively consistent at around 900Mbps when writing copies, XPG is typically below 600Mbps for these actual file transfers. advertised speeds when burning large files (8GB files aren't too big when you factor in backup software, and Blu-ray ISOs are much larger). I would look elsewhere for your next PCIe NVMe purchase. The $99 price tag is great, but not when you realize that it barely competes with standard SATA SSDs for real-world file transfers, which are well below advertised speeds from over-the-top and synthetic benchmarks.
