A high-performance 512 GB M.2 (PCI-E Gen3 4x) SSD in a compact M.2 2280 format. It is positioned as a mid-price product designed for installation in personal computers and workstations. Thanks to its ultra-small dimensions, it is perfect for use in laptops, ultrabooks, nettops and HTPC systems. It features decent I/O performance (380K/390K IOPS), high read/write speed (3500/2300 Mbps), and impressively fast random block access time.
The A-Data XPG SX8200 Pro M.2 SSD ASX8200PNP-512GT-C is based on the Silicon Motion SM2262EN eight-channel controller, working with a 512 MB DDR3-1600 DRAM buffer. Micron's high-quality 64-layer 3D TLC NAND flash memory is used for data storage. To fully realize the speed potential of the device, a motherboard with an M.2 connector is required, which fully supports the PCI-E Gen3 x4 interface (NVM Express v1.3). High-speed dynamic SLC write caching of up to 80 GB is provided, which guarantees the drive's superior performance as a system drive in typical home or professional use scenarios. The guaranteed recording resource claimed by the manufacturer is 320 TB, which corresponds to recording 85 GB of data daily for 10 years.

ADATA XPG SX8200 Pro is an ascetic-looking M.2 NVMe SSD due to the absence of a heatsink, which is now a rarity. However, it is one of the fastest 512 GB PCI-E 3.0 x4 SSDs. Models with even faster PCIe Gen4 interfaces tend to start at 1TB.
Honorary Pioneer
The XPG SX8200 Pro is based on the dual-core SM2262EN controller, the older PCI-E 3.0 Silicon Motion controller. The EN suffix indicates support for an external operational buffer. Moreover, SM2262EN is the first and so far the only SSD controller with support for dual-channel RAM. Therefore, two DDR3L chips with a total volume of 512 MB and a bandwidth of 32 bits (16 + 16 bits) are soldered on the printed circuit board of the drive.
At the limit
A powerful controller and fast RAM cache have a positive effect on IOPS, that is, the number of read and write operations per second — 390 and 380K, respectively. The flash memory in the XPG SX8200 Pro uses 3D TLC manufactured by IMFT, a joint venture between Intel and Micron. The sequential read speed in the Crystal Disk Mark test, regardless of the disk size, is 3500 MB / s, which is almost the maximum throughput of PCI-E 3.0 x4.
virtual array
But the ADATA XPG SX8200 Pro linear write speed varies: 2300 MB / s for the 512 GB version and 3000 MB / s for the 1 and 2 TB versions. In addition, due to the use of TLC memory, a high write speed is maintained only until the volume of the virtual SLC array is exceeded, which is 15 percent of the storage capacity. And this is more than an SSD on a competing bunch of Phison controller and Toshiba flash memory. After the array overflows, the speed decreases by about a quarter and the disk needs time to recover. ADATA offers both the more affordable QLC SSD A-Data Ultimate SU630 ASU630SS-480GQ-R and the slightly more expensive A-Data XPG Spectrix S40G RGB AS40G-512GT-C with a decorated RGB backlight heatsink.
