AnandTech Storage Bench - The Destroyer

The Destroyer is an extremely long test replicating the access patterns of heavy desktop usage. A detailed breakdown can be found in this review. 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 BX100's performance on The Destroyer isn't dead last, but it underperforms for its capacity.

AnandTech Storage Bench - The Destroyer (Latency)

Average service time is startlingly high and is close to a hard drive's seek time.

The frequency of performance outliers is in line with the other two low performers on this test, indicating that the BX200's performance doesn't stutter any more often, but it pauses for longer periods of time when it does stutter.

AnandTech Storage Bench - The Destroyer (Power)

Higher power consumption is to be expected from a drive using TLC NAND, but the BX200 consumed more than twice the energy over the duration of The Destroyer than any of the other drives, and more than five times as much as the BX100. The BX200 didn't take vastly more time to complete The Destroyer, so it was clearly not making good use of idle time.

    I just ordered a couple more BX100's 250GB Reply

    The MX100 was just brilliant, an easy recommendation.The BX100 has been my go to value SSD, that l I recommended to many friends. The bx200 is garbage which costs more? And is about as bad as a HDD. What the hell crucial. What the hell. Reply

    BX100 and MX100 were great.... how can they go backward so badly? Reply

    It's looking more and more as though TLC is a big flop. It doesn't seem to provide substantial price savings, and it comes at a considerable cost in performance, durability, and reliability.

    For a TLC drive to be worth it, it would need to be 1/2 to 1/4 the cost per gigabyte of a MLC solution on the largest drives. It then might be acceptable for people who want moderately priced bulk storage that's cheaper than standard SSDs. But that's not close to being the case now, and it may never be.

    Yeah, I still wonder if TLC is really reliable as producers advertise them.
    Samsung needed a "hack" to their 840 TLC series to solve data retention problems reducing life time.
    We do not know if others have done the same without (obviously) telling publicly. And if 850 series has it under the hood.
    I would go to MLC drives for few $ more. I feel them as more reliable and durable. And "feeling" is an important thing for me, as I put my data on them and saving few bucks may not really be an advantage when a TLC drive lives less then a MLC one.
    For performance, I bet anyone to be able to discern differences in real life form an SSD to another. This are "synthetic" tests, where source of data is faster than SSD speed (RAM). For whatever real usage, anything comes from sources that are slower (HDD, network, optical disks). Load times into RAM is limited, as you don't usually load GB and GB into it but during a benchmark.
    What it really matters is reliability, durability and price. TLC fails to make me comfortable with the first two criteria. Which, for me, are the most important ones.

    These are synthetic tests.

    Yeah it seems like you really need to go to 3D NAND to get decent TLC -- the 850 EVO's have so far been pretty much great. That significantly larger feature size really helps the TLC out. Reply

    No wonder I have been skipping reviews of new SATA SSDs for a few years now. Nothing can touch the Samsung ones, and thats sad. Reply

    Review request: Please do a review of Sandisk Plus, their current lowest tier SSDs available in 120gb and 240gb capacities.
    Will be interesting to see how those compares to the BX100 and BX200 in similar capacities.

    I must buy another BX100 until the stocks will dry... Reply
