Western Digital Adds NVMe To WD Blue

Recommended Posts

Over the years WD has gone through several naming schemes, but their Blue line has consistently been a reliable workhorse sitting in the middle ground between the high-end performance of their Black drives and economy drives. The new Blue SN500 looks to continue that tradition supporting half the sequential reads of the Black line (1,700 MB/s vs. 3,470 MB/s), but also at only a little over half the price ($77.99 vs. $149.99 for the 500MB models). That's still more than three times as fast as the previous SATA Blue models. The write speed ratios are similar although a little more in favor of the BLUE SN500 which WD is reporting can manage 1,450MB/s of sequential writes. Blazing fast for anyone used to the speeds of SATA SSDs. In addition to the 500GB model there is also a 250GB model, both in the tiny 80mm x 22mm x 2.38mm M.2 form factor. WD lists the average active power at 75mW but does not break it by model. This is significantly less than the 110mW drawn by the high-end Black models, but a good 30% more than the old Blue SATA drives with the same capacity.

I'd be curious to see benchmarks, given the controller only has a limited amount of internal DRAM. Which should beat the heck out of actual DRAM-less designs, at least for typical desktop use...
