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 Seagate BarraCuda SSD is broadly competitive with other TLC SATA drives on The Destroyer, with an average data rate that is clearly slower than the best an MLC drive can deliver but is almost identical to the mainstream Crucial MX500, and significantly higher than the Plextor M8V that pairs Toshiba's 3D TLC with a different controller.

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

The average and 99th percentile latencies from the Seagate BarraCuda are lower than any of the competing TLC SSDs, and reasonably close to the best we've measured from SATA drives in this capacity class.

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

The average read and write latencies from the BarraCuda are both among the best we've seen from TLC SATA SSDs, though other current-generation mainstream drives like the Crucial MX500 and Intel 545s aren't significantly behind. The average write latencies in particular vary little among top-tier SATA drives (MLC or TLC).

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

The 99th percentile read and write latencies show more variation between SATA drives than the averages, and here the Seagate BarraCuda continues to distinguish itself by taking the lead among TLC SATA drives, followed closely by the Intel 545s.

ATSB - The Destroyer (Power)

The Seagate BarraCuda's solid performance on The Destroyer comes at the cost of rather high energy usage, almost 40% higher than the Intel 545s that is slightly faster overall. The aging Phison S10 controller is probably the main culprit here, but the Plextor M8V with the same NAND but a Silicon Motion controller is also relatively inefficient on this test.

    "they bought controller designer SandForce right around when SandForce drives disappeared from the market for good."

    That's not strictly true. Seagate still use controllers based on SandForce for some of their enterprise SSDs. Look for DuraWrite Technology in their marketing materials to know which ones.

    SandForce disappeared from the *consumer* market, to be precise. And it was all the more surprising because of how much they shaped the formative years of mainstream SSDs. Reading about the reasons behind that company's implosion in someone's autobiography is going to be interesting. Reply

    I would like to know this also. Did the top brains get hired away to somewhere else somehow right when Seagate bought them or what? Reply

    IIRC Rumor mill at the time was that their next gen controller wasn't competitive and unable to get the design wins they needed they ran out of money and got snapped up on the cheap. Reply

    Nothing was surprising. Every expert knew they wouldnt last long with their focus on compressed performance and manufacturers promoting that without criticism.
    Many customers felt scammed when the controllers never delivered the performance they promised, because the real high numbers were only achievable with compressible content (who the hell has a 5 GB doc file?).

    In every forum experts told people not to buy Sandforce SSDs or memory sticks, because of that fact. That sealed their fate.

    Not competitive on price.

    $84.99 for the 500GB model.

    I just purchased on Dec 4th a brand new Intel 545s 2.5" 512GB SATA III 64-Layer 3D NAND Internal Solid State Drive SSD from Newegg for $34.99 (after $20 PayPal coupon)

    "after $20 PayPal coupon" So, Christmas offerings plus another coupon? Great comparison! Reply

    So show me where I can get the this 500GB model for $54..99 then. That was what I paid pre-coupon for the 512GB Intel SSD.

    Like I said Seagate is not competitive on price.

    I used a $50 Amazon gift certificate to get my Samsung SSD for $4.99. Seagate will never beat that price.
