Western Digital Blue SN570

A fantastic, well-priced all-rounder, as long as you won’t be writing massive files regularly.

Even if you're moving lots of data around, and will thus get limited by the small SLC cache more often, I'd probably still pick the SN570 over those any day. If you're worried about "DRAM-less," check out our benchmark results—I don't see anything in there that would make me go "here, this clearly confirms it's DRAM-less." If you want higher performance, your only option is one of various PCI-Express 4.0 drives, but be prepared to spend almost twice as much per GB.

The WD Blue SN570 is faster than its predecessor, but it isn’t quite as strong during some sustained workloads. Still, at bargain pricing and backed with solid support, the SN570 is a great value if you’re looking for PCIe 3.0 NVMe SSD goodness on the cheap.

The WD Blue SN570, the third iteration of Western Digital's popular budget SSD, is faster than ever and proved a solid performer in our benchmark tests.
