Best 2TB PCIe 3.0 DRAM SSDs
There are 33 2TB PCIe 3.0 DRAM SSDs compared here. The fastest is the Western Digital WD BLACK™ AN1500 NVMe at 6500 MB/s read at 2TB, and the highest-rated for endurance is the Digifast KNIGHT (3115 TBW). Sequential reads across the group span 1800–6500 MB/s at 2TB.
Why this configuration
A 2TB PCIe 3.0 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.
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.
