Over the past few months we have seen a number of companies announcing high-end 2 TB PCIe 4.0 x4 M.2-2280 SSDs, which was not particularly surprising given positioning of these drives as well as expected lonf lifecycle on the market. What is a bit more surprising is that some manufacturers are also expanding their existing product lineups with 2 TB SSDs as NAND prices continue to fall. One of such companies is ADATA, which has just released a 2 TB flavor of its XPG SX8200 Pro.
ADATA’s XPG SX8200 Pro is a version of the company’s Gammix S11 Pro without an aluminum heat spreader, which ensures compatibility with laptops. Both drives come in the M.2-2280 form-factor and feature a PCIe 3.0 x4 interface, they are based on Silicon Motion’s SM2262EN controller (eight NAND channels, four ARM Cortex-R5 cores, NVMe 1.3, LDPC ECC, RAID engine, etc.) accompanied by Micron’s 3D TLC NAND. Previously, these drives only featured 256 GB, 512 GB, and 1 TB configurations, but recently ADATA expanded the family with a 2 TB model.
As for performance, the manufacturer claims that the top-of-the-range XPG SX8200 Pro 2 TB drive offers up to 3.5 GB/s sequential read speed and up to 3 GB/s sequential write speed when pSLC caching is used (data based on CDM benchmark), as well as up to 360K random read/write 4K IOPS. The drive is rated for 1280 TB over a 5-year warranty period.
