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 and 99th percentile 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 Toshiba XG5's average data rate on The Destroyer isn't fast enough to compete with Samsung's drives, but it beats some of the slower MLC-based PCIe SSDs and is much faster than the other (non-Samsung) TLC SSDs.

The average latency of the XG5 on The Destroyer is slower than the top NVMe SSDs including the Samsung 960 EVO, but the XG5's performance is still decent. The TLC-based WD Black and Intel 600p have average latencies that are several times higher. The 99th percentile latency of the Toshiba XG5 is very good, with a third-place score that beats all of Samsung's SSDs.

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

The drive rankings for average read and write latencies are very similar, with the Toshiba XG5 scoring in the middle of the pack on both measures. The overall spread of scores is very different: while the XG5's average read latency is only 25% slower than the fastest SSD and is essentially tied with the Samsung 960 EVO, its average write latency is almost 3.5 times worse than the fastest drive.

The 99th percentile latency scores of the XG5 are great for a TLC SSD. The write latency places the XG5 in the top tier of drives, while its read score is better than average among a widely varying bunch. The Intel SSD 750 is the only drive that offers better 99th percentile latency for both read and write operations.

ATSB - The Destroyer (Power)

Only a handful of drives have ever completed The Destroyer while using less energy than the Toshiba XG5. Most of those were SM2246EN-based SATA drives, and a few other SATA SSDs. The Crucial MX300 and Intel 545s are the only other TLC SSDs with this kind of efficiency. None of the other NVMe SSDs come close; the fastest competitors sacrifice power efficiency to obtain that performance, and the slower NVMe SSDs waste too much power operating a PCIe link that they can't fully utilize.

    Honey, Samsung IS South Korea. Reply

    Look at it from the other perspective. If it wasn't for Samsung, companies like Apple, Dell, HP etc. would barely have any product to sell. The US hasn't been strong in memory for decades and even today Micron is still just a drop in the ocean from overall wafer production point of view. Reply

    Indeed. Reply

    I think you are swimming in conspiracy theory waters. Since there is no legal way to target Samsung specifically, the only way for what you are suggesting is by slapping heavy tariffs on South Korean imports in the US. But that is a dangerous slippery slope, since it could be the start of a global tit-for-tat tariff war. Now, I do not say that Trump is not crazy or stupid enough to not go there, but I still do not think he will do it, because hopefully cooler heads will prevail. If he does the US will be completely isolated, and since it is a major part of the global economy, the 2008 - 2010 crisis will seem like peanuts. Reply

    Don't bother asking him that, it'll just turn into conspiracy theory bullshit. Reply

    This is the second AT story I've read today where the comments devolved into a flame war within the first page. If everyone would just stop feeding the trolls I think things would be a lot better. As it is, the comments area is rapidly reaching uselessness. Reply

    They would have to undercut the 500GB EVO by $75-$100 and the 1TB by $100-$150, at least, to make this thing compelling. Though, to be honest, I haven't noticed a huge difference going from a BX100 to a 960 EVO in everyday performance. It's certainly better for demanding tasks, but that's not important for a lot of people. Reply

    It's odd that Toshiba or anyone would even bother providing press reviews for OEM only products. The general public can't buy them and those who get them through system vendors usually have no choice. Reply

    It's definitely unusual to get sampled an OEM drive, but Toshiba did it this time because the XG5 is their first 64L 3D NAND SSD and is pretty much their flagship client SSD for the next year. It helps that the former OCZ marketing people are now doing PR for all of Toshiba's SSDs, retail and OEM and enterprise. Reply

    Yea, it is basically what SSDs will look like when the NAND shortage ends. Reply
