Random Read Performance

For full details of how we conduct our Iometer tests, please refer to this article.

Iometer - 4KB Random Read

Random read speeds already shed some light to why the Trion didn't perform so well in our Storage Benches as it's simply way behind any other drive. 

Iometer - 4KB Random Read (Power)

While the Trion isn't the most power hungry drive, it certainly consumes more than it should given its low performance.

OCZ Trion 100

The Trion starts from the bottom because its QD1 performance at 16-20MB/s is significantly below the rest and the scaling isn't aggressive enough to make up for the difference. High queue depth performance isn't outstanding either, but luckily that has much less relevance in the real world.

Random Write Performance

Iometer - 4KB Random Write

Unfortunately random write performance doesn't show any better signs. The Trion is again at the bottom of the chart by a quite substantial margin.

Iometer - 4KB Random Write (Power)

Power consumption, on the other hand, is fairly high, making the Trion one of the least efficient drives.

OCZ Trion 100

There is effectively no scaling with queue depth at all, which I find strange. I suspect this is a limitation of the firmware because with 1TB of TLC NAND there should be enough NAND bandwidth to scale, but obviously if the firmware is inefficiently designed that doesn't happen.

    Published endurance ratings != actual endurance!!!

    Published endurance ratings are only used for two reasons:
    1) To keep write heavy enterprize users away
    2) For warranty purposes (A published endurance rating gives a hard cutoff for the end of warranty period, besides the time period running out)

    ACTUAL endurance of the NAND is usually WAY higher, especially with the Samsung 850 series drives.

    It looks like these drives have had their endurance validated according to the JEDEC JESD219A client workload specification, which means it's actually a meaningful value rather than one arbitrarily set by the manufacturer to keep heavy users away. Reply

    I'm really really really curious to some data retention measurements. I would appreciate it greatly if AT would throw some MLC and TLC SSD's in the vault for half a year and then report back with an awesome review! Reply

    Looks like the Trion is a drive to bypass. Maybe they'd do better with a drive called the "Succeedon". Reply

    Samsung's 850 line looks poised to have as much staying power as the 830s (luckily I skipped the buggy 840 EVO since I wasn't looking for more capacity at the time)... Looking forward to some BF or Amazon's 20th deals on that 1TB 850 EVO! (tho I probably should've just bought it when it hit $340 not long ago) Is Samsung releasing a new series early next year or are they all about PCI-E/M2 moving forward? Reply

    2.5" SSDs aren't going away anytime soon, so I'm sure we'll see Samsung 860 series SSDs in the future. How soon is the question, because it seems there's not much that can be done to speed up drives without having them bottlenecked by SATA3 and AHCI. Reply

    The advances for the 860 series are likely to focus on density rather than performance upgrades. However, there is still a lot of room for improvement in random IO performance. Reply

    Samsung already announced 2TB 850 Evo and Pros, the prices look pretty good also. Its gonna be hard to top the 850 series!

    You guys act like the 840 EVO was the worst drive in the world. I've had 0 problems with mine in the year that i've owned it and couldn't be happier. Reply
