Best 500GB PCIe 3.0 Intel DRAM SSDs
There are 4 500GB PCIe 3.0 Intel DRAM SSDs compared here. The fastest is the Intel INTEL® SSD 670P SERIES 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 Intel 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. Intel 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 Intel means consistent firmware, tooling and warranty handling across the range.
