Best 500GB PCIe 3.0 ADATA DRAM SSDs
There are 10 500GB PCIe 3.0 ADATA DRAM SSDs compared here. The fastest is the ADATA XPG SX8100 at 3500 MB/s read. Sequential reads across the group span 1800–3500 MB/s at 500GB.
Why this configuration
A 500GB 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.
500GB is a sensible OS-plus-a-few-games size.
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
500GB is a comfortable OS-and-games starting point.
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.
