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, 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. These AnandTech Storage Bench (ATSB) tests do not involve running the actual applications that generated the workloads, so the scores are relatively insensitive to changes in CPU performance and RAM from our new testbed, but the jump to a newer version of Windows and the newer storage drivers can have an impact.

We quantify performance on this test by reporting the drive's average data throughput, the average latency of the I/O operations, and the total energy used by the drive over the course of the test.

ATSB - The Destroyer (Data Rate)

The overall performance from the 500GB and 1TB SK Hynix Gold S31 drives on The Destroyer is a bit slower than typical for mainstream SATA drives, but it's not a large gap.

ATSB - The Destroyer (Average Latency)ATSB - The Destroyer (99th Percentile Latency)

The average latency scores from the S31 on The Destroyer are reasonable, but again slightly behind the other mainstream SATA drives we've tested. The 99th percentile latency scores rank a bit better, and are definitely competitive. The 250GB model's performance is substantially worse than the larger two models.

ATSB - The Destroyer (Average Read Latency)ATSB - The Destroyer (Average Write Latency)

Both the average read and write latency scores show similar rankings for the S31s, with the 250GB model's latencies are roughly double that of the 500GB model, and the 1TB only slightly faster than the 500GB.

ATSB - The Destroyer (99th Percentile Read Latency)ATSB - The Destroyer (99th Percentile Write Latency)

The 250GB S31 turns in the worst 99th percentile read latency score out of this batch of drives, but the 500GB's score is competitive, and the 1TB model's score is at the top of the chart. For 99th percentile write latencies, the three S31s rank much closer together, and the slowest 250GB model is still vastly faster than the DRAMless SSDs.

ATSB - The Destroyer (Power)

The 500GB and 1TB models of the SK Hynix Gold S31 turn in very good energy usage scores, while the smaller 250GB model ends up with efficiency that is merely typical for this class.

    We're not going to get under 10c/GB anytime soon, will we? SATA SSDs seem to be stagnant - performance is OK, power consumtion is OK, price is $100 for 1TB, endurance is the usual 0.3 WPD - and yet there are constantly new products with different components and basically the same performance/power/price.

    Is there a limitation that currently causes stagnation? (I know that SATA is inherently limited in performance, but price shouldn't be stagnant if the main need in that sector is more capacity for less money, with performance/power/endurance being the same)

    "price shouldn't be stagnant if the main need in that sector is more capacity for less money"

    all of these companies face the Tyranny of Fixed Cost, i.e. the BoM is almost all amortization of the plant and equipment to make the various bits and pieces. sand, some chemicals, and a watchman or two to hover over the machines amount to the variable cost. in such a situation, the only way to lower *average cost* (and shut up the bean counters) is to ship more product and thus spread the fixed cost a tad thinner. lots more product. but that, in turn, is strictly limited by user demand. they're caught between a rock and a hard place. they end up viewing the situation as zero-sum game; one can win only if the other(s) lose when there's little to no global (in every sense of the word) growth. welcome to Earthly Stagnation.

    Having Dr ManHattan looking after your machines is a very expensive business , Rorschach is very unreliable too. Reply

    Except prices have been falling. You just don't realize it because it happens over time.

    These drives are as cheap as Samsung's QLC drives, without the disadvantages.

    SSD prices have been basically flat since October/November 2018. Check the price tracking for a 500GB/1TB MX500 or 860 Evo and there have been a few variations but nothing substantial or permanent.

    I'd love to pick up more large capacity solid state to replace some of my HDDs, but I bought two 2TB SSDs over a year ago and they're actually a few dollars *more* expensive now.

    At this point, it may actually be cheaper to build a large NAS using MicroSD cards...

    I paid the same amount for my 2 TB 970 evo as I did my 1 TB 960 evo 2.5-3 years ago. Also, don't track specific drivers, look at charts. NAND is coming down. It just takes time. Reply

    /s implied with respect to the MicroSD card NAS, if it weren't obvious.

    Although that would be fun to build.

    Sale prices are hitting 8c/GB. Don't pay 10c/GB if you live in America. As the average drive capacity goes up, the prices will continue to go down.

    Thankfully, 100 GB and larger games are a thing, so that should create some demand.

    we might PLC coming soon, so we might see some 1 TB/1.5 TB/2TB/3TB sata's soon and as they are 20% bigger after amortization wears off, almost 20% cheaper it will become.
    main focus will go to PCIE4.0 now though. so I would say next December expect 2 or 3 products with same nand. 120GB/240 will not go lower than its is now.

    in there on the article. We already did on 1 TB ones. and PLC will go even lower.
    ADATA SU800 $34.99
    (14¢/GB) $57.99
    (11¢/GB) $91.99
    (9¢/GB) $209.99
    (10¢/GB)
