![]() The 500GB model represents the best value at $139.99. The drives should sell at MSRP at first and then decline over time. The Western Digital Blue series is available now. LDPC extracts more endurance from the underlying flash than BCH ECC, which leads to more longevity from cheap planar NAND. LDPC keeps the SanDisk 15nm 3-bit per cell (TLC) NAND in line with a two-tier hard and soft decision approach to error correction. WD based the drive on the Marvell 88SS1074 "Dean" 4-channel controller that supports low-density parity check (LDPC) error correction code. The two high-capacity models offer the best performance, but the 250GB only trails by a small amount. The Blue peaks at 545 MB/s sequential read and 525 MB/s of sequential write speed, while random performance tips the scales at 100,000/80,000 read/write IOPS. The Blue SSDs sport slightly higher performance and endurance compared to the X400. The client-focused X400 crossed over to the mainstream market due to the vacuum created when SSD manufacturers attacked the entry-level segment and ignored the mid-tier. Western Digital tells us that it changed the firmware, but we don't have many details. The Blue's hardware is identical to the SanDisk X400 we recently tested, and it ships in both 2.5" and M.2 2280 (AHCI SATA) flavors. The new Western Digital Blue series SSDs come to market in three capacities that range from 1TB to 250GB. $82.99 (opens in new tab) at Newegg (opens in new tab) ![]()
