A number of Austrian retailers have recently begun to list Western Digital’s as-yet-unannounced WD Blue 4 TB SSD. The drive features a SATA 6 Gbps interface and performance you can expect from such storage devices, yet if you need 4 TB of NAND flash storage in a 2.5-inch/7-mm form-factor, the WD Blue 4 TB SSD is one of a handful of options.

Originally launched in mid-2017, the WD Blue 3D NAND SATA SSDs are based on Marvell’s 88SS1074 controller as well as WD/SanDisk’s 64-layer 3D TLC NAND memory. When it comes to performance, the drives are rated for up to 560 MB/s sequential read speed and up to 532 MB/s sequential write speed (when pseudo-SLC cache is used), which is something that all advanced SATA SSDs offer these days. As for random reads and writes, we are looking at 95K IOPS and 84K IOPS, respectively, which is comparable to other mainstream SSDs with the same interface.

Initially available in 250 GB, 500 GB, 1 TB and 2 TB configurations, the 4 TB WD Blue 3D NAND SATA SSD (WDS400T2B0A) is now listed by multiple Austrian retailers, according to the Geizhals.at price search engine. The 4 TB drive is priced at €555 - €575, a high price, but consistent with the premium that top capacity SSDs normally carry.

Neither retailers nor Western Digital are disclosing when the WD Blue 4 TB SSD is set to become available (i.e., we do not know whether this is an EMEA-specific product or it will be available in other regions too), but stores typically don't list products until they're close to release. So we're expecting the drive to hit the market sooner rather than later.

While SSDs have made a great progress in terms of capacity in the recent years, 4 TB 2.5-inch/7mm consumer drives are still rare. For example, Samsung, the world’s largest supplier of SSDs, offers only two 4 TB SATA models in its entire consumer lineup: the Samsung 860 Evo 4 TB featuring TLC NAND and the Samsung 860 QVO 4 TB featuring QLC NAND memory. So the addition of a 4 TB consumer drive from WD expands the number of options considerably.

    Newegg was selling the 1TB Blue 3D NAND for $99 last week. 3D NAND, five-year warranty, DRAM, and pure SATA3 6Gb/s saturation? Ya can't go wrong, folks. This was for an off-site backup, so not having NVMe (and finding a NVMe -> USB controller) was actually a plus. Reply

    $100/gb = count me in. I want NVME though. I still have 2 more slots to fill. I want to get the 2 tb evo plus for all 3 slots, but damn, already spent a ton for my 1 tb 960 evo. Reply

    Well at $100/gb it would only cost $600k :P Reply

    I think $100/gb is very steep... I'm not sure what "g" means, but I'm going to guess "Giga", as would normally be accepted with a capital G. Lowercase b, though, that's unambiguously "bit", NEVER byte. Therefore $100 per gigabit. That's expensive. Really expensive. This SSD at that price would cost $3,200,000. Reply

    Thanks, I was procrastinating to write this explanation. Reply

    Pretty sure you were trying to say 1 "TB" not "GB". Reply

    But do you really need super fast nvme for all drives? On my side, for my "slow" storage I use Intel 2TB 660p as it is cheaper and still much faster than a SATA SSD. Reply

    The 4TB is going to be much more per TB than that, just like how the 4TB Samsungs sell at a large premium. WD is not going to undercut themselves Reply
