Well, unfortunately, the synthetic benchmarks are just that and you should take the them with a grain of salt. 1) at least Samsung now shows the performance of the drives when they run out of TLC cache on the EVO and EVO Plus. When transferring large files, expect no more than 900Mbps write for the 500GB Samsung EVO drives. On the XPG, I can't find that information on their website, but after several of my own 8GB single file transfers to this drive, it usually falls between 400Mbps and 600Mbps in a matter of seconds and fluctuates in that range, although occasionally reaching 900Mbps for very brief periods. This is a far cry from the 500GB versions specifications and we'll below the capabilities of my existing and older/smaller PCIe NVME drives.
You might say these speeds are based on my hardware or the file being transfered, but then why do the older drives in my system still perform better under the same conditions and closer to their advertised speeds? My older 256GB Samsung 950 Pro still outpaces it with a steady 900Mbps on the same file writes and my other first generation MyDigital BPX 500GB also sees 900Mbps writes with the same file tests. I've also swapped the 3 drives so they each test the file copies in the onboard m.2 slot and the 2 different PCI adapters on the 16 and 8 lane slots. While the Samsung and BPX are relatively consistent at about 900Mbps write copies onto them, the XPG is usually below 600Mbps in these real world file transfers.
So, yeah, it meets the Crystal DiskMark "test" specs, but performs leaps and bounds slower than the advertised speeds when it comes to writing larger files (8GB files aren't overly huge when you consider backup software and Blu-ray iso's are much larger).
I'd look elsewhere for your next PCIe NVMe purchase. The price is great at $99, but not when you realize it's barely on PAR with standard SATA ssd's in real-world file transfers that fall well below the advertised speeds of inflated and synthetic benchmarks.
Note that laptop benchmarks were lower; I put this in my desktop to get a maximum figure from CrystalDisk.
I did stick the heat spreader on because, in my laptop, it has to make contact with a plate for heat dissipation, and I removed the OEM crappy silicone-feeling sticky 'thermal pad' and replaced it with AS5. Wondering if perhaps I should've done that on the inside of the ADATA plate too.
FYI: this benchmarks much higher than the sister product, the Gammix S11, but ADATA just announced a 'Pro' version of that one too. We'll see how it is.
For now, at this price (215 presently), you really can't beat it for a 1TB drive. Buy this one, not the S11 or XPG non-Pro.
Update: As prices fell, I bought a second 1TB SX8200 Pro for my desktop and couldn't be happier. And as of writing this, there's even a coupon for it. Unbelievable value. Now, there are some people who say these synthetic benchmarks aren't indicative of real-world performance; this is true IF you use these drives as bulk-file storage. This is how higher-density (3D/QLC/etc.) NAND flash works - it's slower and backed up by a tiny amount of lower-density, much faster cache that runs out. But that's why people who need huge storage still buy several 3TB+ mechanical HDDs, right? Very few people reading this are probably trying to move terabytes of ISO or raw video files daily with their nVME drives (unless you do it as a profession, in which case money is no object, and you probably have a company NAS) - you're probably going to use it as a game and OS drive, which this is perfect for, with a few hundred/thousand tiny files being read in random orders to load up Battlefield or Overwatch or Windows, rarely being written to in solid sequential order for gigabytes upon gigabytes except during a one-time install. In other words, this is perfect as a game/OS drive, not for a large video/storage cache.
