AnandTech Storage Bench - The Destroyer

The Destroyer is an extremely long test replicating the access patterns of very IO-intensive desktop usage. A detailed breakdown can be found in this article. Like real-world usage and unlike our Iometer tests, the drives do get the occasional break that allows for some background garbage collection and flushing caches, but those idle times are limited to 25ms so that it doesn't take all week to run the test.

We quantify performance on this test by reporting the drive's average data throughput, a few data points about its latency, and the total energy used by the drive over the course of the test.

AnandTech Storage Bench - The Destroyer (Data Rate)

The WD Black's average data rate on The Destroyer is a little bit slower than the fastest SATA SSD of comparable capacity, and much faster than the Intel 600p. The Samsung 960 EVO is the only TLC-based SSD we've tested that outperforms the WD Black.

AnandTech Storage Bench - The Destroyer (Latency)

While the WD Black's average data rate didn't quite beat the best SATA SSDs, its average service time is substantially better than the Samsung 850 PRO, though nowhere close to most MLC PCIe SSDs.

The WD Black is no better than the Samsung 850 PRO at avoiding high-latency outliers above 100ms, but the WD Black has a significant advantage over all SATA SSDs at the 10ms threshold.

AnandTech Storage Bench - The Destroyer (Power)

The WD Black's power efficiency during The Destroyer is poor, with total energy usage that is higher than almost all of its competitors.

    At least they priced it about right. It's more expensive than the Intel 600p, but far less expensive than the 960 EVO and slightly less expensive than the M8Pe. This part of the market is odd. Usually, the fastest performing parts are FAR more expensive for just a small return on performance. In SSDs right now, the differences in price are fairly small, but the differences in performance are huge. I think the 960 EVO is about the best deal for a SSD, and this thing is just a shame to the "Black" label. Reply

    So, the product called "WD Black" is coloured blue, but there is also a "WD Blue" product? Let me guess, that one has a black PCB? Reply

    Nope, it would have made sense if they spent the money to use a black pcb for the black drive, a blue pcb for the blue drive and the green pcb for the green drive. Nope.

    This drive gives the "Black" label a bad name anyway.

    They probably thought "our Black HDDs are really slow nowadays, with all those budget SSDs around, so let's call a barely-not-too-slow SSD: BLACK". Reply

    WD Black: planar 15 nm TLC NAND

    I'll be sure to remember that WD doesn't give a shit about the quality and performance of their products and branding. Way to dilute the brand, hope the short term gains are worth it.

    The branding is fine, the wd green ssd will be a qlc nand drive. Reply

    True, black has always been the performance line, it shouldn't go on any TLC parts. Not even on 3D TLC. Reply

    On your Storage Bench - Light (Latency) graph, you show the Intel 750 and Patriot Hellfire on top despite the Samsung drives beating them both in "Full" condition. So if they tie on the empty drive score, the Samsungs should be on top due to their full drive latency. Reply

    How come you didn't test any drives that use the Phison E7 controllers? Patriot Hellfire, MyDigitalSSD BPX, and Corsair Force? Reply

    This certainly isn't an impressive product. Reply
