The Western Digital Blue 3D 4TB SSD, with the part number WDS400T2B0A, should still feature the same Marvell 88SS1074 controller and SanDisk's 64-layer 3D TLC (triple-level cell) NAND flash chips like on the other capacities. While the previous flagship 2TB variant was available in traditional 2.5-inch and M.2 2280 formats, it's uncertain if this new 4TB variant will follow suit. Meanwhile, the 4TB model comes in the 2.5-inch form factor with a thickness of 7mm and runs off a SATA III connector.

The Western Digital Blue 3D 4TB SSD performs similarly to the 500GB and above models. The drive delivers a sequential performance of 560 MB/s read and 530 MB/s write. Random performance is rated for up to 95,000 IOPS read and 82,000 IOPS write. The SSD carries a 600 TBW (terabytes written) rating. Western Digital backs the SSD with a limited five-year warranty.

Although the retailer didn't reveal the Western Digital Blue 3D 4TB SSD's pricing, Lithuanian retailer Skytech listed the drive for 546 Euro, which roughly converts to $608.94. Deducting the 21 percent VAT (value-added tax) rate from the price brings it down to $503.26 and comes out to 13 cents per gigabyte. The price tag seems to fall in line with the other drives' pricing.

eD system states that the Western Digital Blue 3D 4TB SSD will be available on May 13. The new drives should be making their way over to this side of the world, assuming they aren't hiding among us already.
