OCZ Trion 150 SSD Review

OCZ is on its second-generation TLC-based effort. The new Trion 150 updates the flash to Toshiba's 15nm TLC, but the largest improvement comes from firmware that increases sustained write performance.

Why you can trust Tom's Hardware Our expert reviewers spend hours testing and comparing products and services so you can choose the best for you. Find out more about how we test.

Four-Corner Performance Testing

Comparison Products
ADATA SP550 (480GB)
Crucial BX200 (480GB)
Mushkin Reactor 512GB

Nearly all of the drives on this chart utilize TLC flash with write enhancement technology (an emulated SLC cache) to deliver burst speeds that are not sustainable for more than a few seconds. Samsung's 850 EVO is the current mid-range performance leader. Its quad-plane TLC is the exception to our rule, delivering burst writes for longer than SSDs with TLC flash from either Toshiba or Micron.

Sequential Read

Every company with a SATA 6Gb/s drive says its sequential read performance lands between 540 MB/s and 560 MB/s. Given the power of today's controller's it's easy to hit the interface's ceiling using this workload. Drives are still differentiated at low queue depths, though.

The Trion 150 makes quick work of its predecessor, beating it by more than 40 MB/s at a queue depth of two. OCZ's 960GB model is on the chart as well, but we're really only talking about the 512GB-class drives.

Sequential Write

Updated firmware more than doubles the sequential write performance at a queue depth of two compared to the original Trion. OCZ now has a TLC-based SSD that competes readily in the value-oriented space. In fact, it comes close to beating Mushkin's 512GB Reactor, which utilizes MLC flash.

You can also see that the Trion 150 smooths out some of the variance between when the emulated SLC buffer kicks in and TLC's native write behavior.

Random Read

The Trion 150's random read performance is only marginally better than its predecessor. Adata's SP550 still outperforms the 480GB Trion at a queue depth of one. And none of the other drives in our chart, including the 960GB Trion 150, can match Samsung's 850 EVO at low queue depths.

Random Write

All of the TLC-based drives except for Samsung's 850 EVO suffer low random write performance.

Toshiba, Micron and SK hynix all fall behind Samsung when it comes to vertical NAND stacks with quad-plane access. Toshiba didn't like something about its first 3D flash, which the company calls BiCS. BiCS 2 is already under development, but is still not ready for SSDs. OCZ needs that next-gen technology to compete more aggressively against Samsung in the high and low ends of the market.

    is anyone else still kind of blown away that SSD's are getting this cheap? maybe im just in a nostalgic mood but I remember when SSD's cost a TON more than this and now were seeing 960gb for almost a quarter a gb

    I'm right there with you. I picked up a 480 gb Sandisk Ultra II over black friday for $110. I was pretty happy with that.

    The value has gotten quite good. I also beliew SSDs are at a good value point right now. Sure, they can go lower and closer to HDDs in cost/GB, but you also don't want HDD performance, power consumption, or weight.

    OCZ products on the other hand are complicated. Seeing early review returns from actual customers isn't going so well. Some SKUs are showing early failures just like the Trion 100. OCZ needs to make a few drives that are so reliable none fail. Supercaps, full pfail circuitry, two controllers, whatever even at a loss if necessary. OCZ's enemy is reputation and reality.

    When your OCZ ssd runs out of IOPs or fails, try to reflash it, sometimes it will reset the # of IOPS and put it back to 0 and it will work again....

    cheap to the point that in my next computer i was considering a 512gb drive, but now im looking at 900+gb drives... not so much for their boot as i could get by with a 256 drive for just that, but as a loading heavy game drive too.
    granted the next pc i build will get partitioned to hell and back due to the boot options i want, possibly a win 7 partition, a second one that is just os for emergency my main os crapped up, win 10 and the same, then some linux distros for playing around with. should be able to get all that and my required programs to run on less then 300gb, so the rest could be for load heavy games.

    Terabyte SSDs are flirting with the $200 barrier. Quite nice, but I'm going to hang onto HDDs for secondary storage for a while longer.

    At the sacrifice of overall speed and endurance.

    At the sacrifice of overall speed and endurance.

    That implies you actually need that additional speed and endurance though. How many users need a drive that can handle a petabyte of writes? It's unlikely that you'll write much more than a terabyte of data to your system drive each year, so write endurance shouldn't matter much outside of specialized usage scenarios like database servers. I'm not sure if you ever saw that endurance test that Tech Report ran, but they performed continuous writes on various SSDs until failure...

    https://techreport.com/review/26523/the-ssd-endurance-experiment-casualties-on-the-way-to-a-petabyte

    Their 250GB Samsung 840 Evo with TLC flash survived over 900TB of writes in that test, and they didn't detect any uncorrectable errors until after 200TB. That would be over 100 years of typical desktop usage, making the endurance of the TLC a non-issue.

    And as for performance, just look at the "Real-World Software Performance" benchmarks here. All these drives perform very similarly under most usage scenarios to the point where it's unlikely you would notice any notable difference between them in day to day use. Software is still designed with the performance limitations of hard drives in mind, so aside from perhaps large file transfers and some other fringe scenarios, you're not likely to see a huge difference in performance between lower and higher end SSDs.

    And ultimately, if the endurance is far higher than what people using the drive will actually need, it makes sense to trade some of that headroom for additional capacity. Cost per gigabyte is the main thing holding SSDs back from universal adoption over hard drives, and multi-level cell flash is helping to bring those prices down to be competitive.

    The elephant on the room is reliability. People tend to buy large storage to hold their valuable data. If performance is what they need, RAID 0 of small disks usually is enough.

    OCZ is not well-known for their reliability, and most people do not want to store their valuable data on unreliable media. In past few years, I only used Samsung and Intel brands for SSD, yes they cost higher than competing brand like OCZ, but (at least) to me, the value of my data are even higher than that.

    So, are they improved their reliability ? I do not want to to loose my dear data overnight because like some people here, I only backup my personal data once a week.

    OCZ had major reliability problems in the early Sandforce days, that's for sure. They were actually improving later on as firmware problems were ironed out and so on. They probably just jumped on the Sandforce bandwagon a bit too quickly. Anyway, improvements or not they went bankrupt. Toshiba bought them up, and if they weren't high quality before, they are now.

    Meanwhile, Samsung has had its misstep with the 840 and 840 Evo. But their 850 Evo is great. Again it seems like being an early adopter, this time of TLC NAND, caused issues.

    Personally I have an OCZ Agility 3 from 2012 (before the bankruptcy), and it's running just fine. Not that it proves much.
