AnandTech Storage Bench - Heavy

While The Destroyer focuses on sustained and worst-case performance by hammering the drive with nearly 1TB worth of writes, the Heavy trace provides a more typical enthusiast and power user workload. By writing less to the drive, the Heavy trace doesn't drive the SSD into steady-state and thus the trace gives us a good idea of peak performance combined with some basic garbage collection routines. For full details of the test, please refer to the this article.

AnandTech Storage Bench - Heavy (Data Rate)

Ouch, this doesn't look too good. Even out of the TLC drives the Trion 100 is the slowest of the bunch and the difference isn't marginal either (~25% drop in data rate at 240GB compared to the Ultra II). 

AnandTech Storage Bench - Heavy (Latency)

The latencies actually show a worse phenomenon as MLC based drives (even the Neutron XT) all easily stay below 800µs, whereas TLC drives start at 1,000µs and the Trion even goes above 1,500µs.

Unsurprisingly, the high average latency shows up as an increased share of high latency IOs.

AnandTech Storage Bench - Heavy (Power)

Not only is the Trion slower than the rest, it also consumes more power. To be honest, I don't mind a lower performance drive if the decreased performance translates to lower power consumption, but if that doesn't happen then the whole design is simply inefficient like in Trion's case. As I've mentioned before, TLC is inherently less power efficient so increased power consumption over MLC SSDs is expected, but I still think the Trion could use some better optimization.

    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
