Adata’s combination of Micron's 64-Layer flash and Silicon Motion’s SM2262 controller scored a home run in the SX8200 and GAMMIX S11 SSDs that were among the best high-performance NVMe SSDs of 2018. The SX8200 takes that rich tradition and builds on it.
The Silicon Motion SM2262EN makes Adata’s XPG SX8200 Pro a fierce competitor, as, at publication time, it had remained in the top spot on our best SSDs page for several months.
Based on our testing, we’re quite impressed. The SX8200 Pro easily served up 3.5 GBps of read throughput and 3 GBps write speeds, even as the workload intensified. This professional-class SSD even trades blows with Samsung’s 970 series and often outperforms most SM2262-based SSDs.
Perhaps most importantly, the SX8200 Pro outperforms every other flash-based SSD in real-world tests. The drive excelled in SYSmark and loaded game levels faster than any drive we’ve tested. It also notched an average bandwidth of 765MB/s, second only to the Samsung 970 PRO, which costs more than twice as much, and over 200 MBps faster than the GAMMIX S11.
Not only do we see strong performance under load, but we also see fantastic efficiency. We measured 189 MBps per watt, which is almost 50% better than any other SSD in its class. That's impressive for a TLC SSD with less overprovisioning than competing models.
The SX8200 Pro does have a few downsides, though. While it boasts a five-year warranty, it has the same endurance rating as the Adata's non-Pro equivalents. If you're after an alternative to the high-endurance Samsung 970 PRO, the SX8200 Pro is not the best option: The drive’s endurance ratings are one-third that of Phison E12 powered SSDs like the Corsair Force MP510 and MyDigitalSSD BPX Pro. This is a concern for professional use-cases, but the endurance rating is enough for enthusiasts.
Adata prices the XPG SX8200 Pro at ~$0.11-0.13 per GB (at press time), which makes it an absolute steal. Even If you're searching for a new high-performance NVMe SSD and don't require workstation-class endurance, the SX8200 Pro is probably your best choice.
