Average Bench: 160% (130th of 1058)

Based on 9,827 user benchmarks.  Models: ADATA SX8200NP, NVMe ADATA SX8200NP

Adata’s XPG SX8200 offers NVMe PCIe SSD performance at SATA SSD prices, thereby offering outstanding value for money to casual and power PC users alike. Adata have combined two high performance commodity components: a Silicon Motion controller (SM2262) and Micron’s second generation 3D TLC 64 layer flash memory. The XPG SX8200 also includes a generous SLC cache and a DRAM cache buffer. Adata have not specified the exact size of the SLC cache in each model but it’s clear from our 60 second sustained write tests that the buffer is sufficient for more than 60 seconds of continuous writes which equates to over 60GB (60s x 1 GB/s) for the 240GB model and over 90GB (60s x 1.5 GB/s) for the 480GB and 960GB models. Unlike many other drives with SLC caching, the SX8200 has a large enough cache to ensure that consumers will almost always operate the drive within the cache and therefore experience no write degradation at all. Adata offer a 5 year warranty and a limited TBW warranty (160 TBW for the 240 GB version, 320 TBW for the 480GB and 640 TBW for the 960GB) on these SSDs, which is in line with other premium manufacturers. The NVMe PCIe SSD consumer market has been dominated by Samsung in recent years but the 240GB SX8200 beats Samsung’s 250GB 970 Evo hands down on both price and performance (the 250GB 970 Evo is let down by a relatively small SLC cache which allows for less than 10 seconds of writes before saturation after which the write speed on the Evo drops to mere sub SATA 300 MB/s). The SX8200 is the new value leader and heralds a new era of competition for the mainstream segment of the NVMe SSD market. [Jul '18 SSDrivePro]

Outstanding average bench

The Adata XPG SX8200 NVMe PCIe M.2 240GB averaged 60.0% higher than the peak scores attained by the group leaders. This is an excellent result which ranks the Adata XPG SX8200 NVMe PCIe M.2 240GB near the top of the comparison list.

write speeds are not as advertised (only 500mb/s)

I used this for a while. It was very good, no problems. After some time though, it just stopped working properly. Just give a hundred more dollars and get a better one. Worth the price, but there are better and more worth ones.
