On what would have been the first day of the Open Compute Project's annual Global Summit, Western Digital is bringing out a new line of enterprise SSDs. The WD Gold brand for enterprise drives is getting an SSD counterpart to the existing WD Gold enterprise hard drives. WD's color-based drive branding now features both SSDs and hard drives in almost every product segment: Blue and Green mainstream consumer drives, Black for high-end consumer, Red for NAS systems, and Gold for enterprise. The only one missing an SSD option is the WD Purple family for video surveillance recording (though there is a WD Purple microSD card).

The new WD Gold SSD isn't anything new technologically; it's basically a re-branding of a portion of the Ultrastar DC SN640 product line. Where the WD Gold differs is in the target markets: Like other WD (color) products, the WD Gold SSD is intended for channel and retail sales rather than the large-scale direct B2B sales model used for Western Digital's Ultrastar datacenter drives and their client OEM drives. The WD Gold SSD will make Western Digital's enterprise SSD technology more accessible to small and medium enterprise customers.

The WD Gold SSD is based on the same hardware as the Ultrastar DC SN640 series, but the WD Gold product line doesn't include as many options. The SN640 comes in two endurance tiers: 0.8 drive writes per day and 2 DWPD. The WD Gold SSD line only includes the 0.8 DWPD drives, and only the U.2 form factor versions: a total of four capacity options from 960 GB up to 7.68 TB. These drives use the latest Western Digital/Kioxia 96-layer 3D TLC NAND flash memory and one of Western Digital's own in-house NVMe controller designs.

The technical specs for the WD Gold SSDs are identical to the matching Ultrastar DC SN640 models. The performance is limited largely by the PCIe 3.0 interface and the power/thermal constraints of the 2.5"/7mm U.2 form factor: these drives idle just under 5W and can draw up to 12 W under load, with configurable power states to throttle down to 10 or 11 W for high-density deployments that can't quite keep them cool at the full 12W each.

The WD Gold SSDs are planned to ship starting in early Q2. Pricing has not been announced.

    The only thing it costs is space, the 960gb corsair mp510 has 1 dwpd. Reply

    “I just expect higher end components to be used in enterprise gear”

    You have no idea what you’re talking about. TLC NAND has been used in enterprise SSDs for years now.

    You should look at TBW endurance of enterprise spinning hard disks. They can’t even compete with many consumer-level SSDs that utilize TLC NAND.

    But please, don’t let me stop you from being an idiot.

    I'm waiting on 3.5" full SSD 20TB+ drives... oh also... has to be dirt cheap! lol Reply

    Yet again, no pricing on a product that could be shipping in less than a month.

    @Anandtech are you really this desperate for clicks?

    Agreed. And "articles" like this are informational. They are not advice or deep-dive reviews. For those planning to make purchases, small or large, in the future, articles like this are beneficial. Pricing is very important but it is not the end-all be-all to purchasing decisions. Reply

    Idle power looks very high ? 4W really ? Reply

    For NVMe with power loss protection, that's not unusual. Reply
  • Billy Tallis - Sunday, March 8, 2020 - link

    Power loss protection has little or nothing to do with it. Enterprise drives have high idle power because they're designed to offer consistently low latency. Waking up from a deep sleep state like consumer SSDs use would ruin the latency metrics. Reply
