Best 2TB PCIe 3.0 ADATA DRAM SSDs
There are 4 2TB PCIe 3.0 ADATA DRAM SSDs compared here. The fastest is the ADATA XPG SX8100 at 3500 MB/s read at 2TB.
Why this configuration
A 2TB PCIe 3.0 ADATA DRAM SSD is an affordable NVMe step up from SATA. Gen3 is roughly six times SATA's throughput yet often costs little more, making it the easy default for a first NVMe drive or a laptop that only supports Gen3. ADATA specifically tends to be chosen here for its firmware track record and warranty support.
2TB is the current default for people who'd rather not think about free space for a while.
Usually chosen for: budget builders, laptop upgraders and anyone leaving SATA behind.
Good fit: workstation and creative loads that hammer random I/O.

The parts, explained
2TB is today's sweet spot for large game libraries and creative work.
PCIe 3.0 x4 reaches about 3,500 MB/s — plenty for everyday use and gaming, and cheaper than Gen4.
An onboard DRAM cache keeps the flash mapping table on the drive, holding random performance steady under sustained load.
Staying with ADATA means consistent firmware, tooling and warranty handling across the range.
