Idle Power Consumption

Since we truncate idle times to 25µs in our Storage Bench traces, they don't give a fully accurate picture of real world power consumption as idle power consumption is not taken properly into account. Hence I'm still reporting idle power consumption as a separate benchmark because it's one of the most critical metrics when it comes evaluating an SSD for mobile use.

Unfortunately I still don't have a way to test DevSleep power consumption due to lack of platform support, but my testbed supports HIPM+DIPM power commands (also referred to as Slumber power), so the results give a rather accurate picture of real-world idle power consumption. 

Idle Power Consumption (HIPM+DIPM)

The Trion is the first OCZ SSD to include support for low-power states and that's clearly visible in our results. It's not the lowest power drive we have tested, but falls in the same range as the majority of drives. 

TRIM Validation

The move from Windows 7 to 8.1 introduced some problems with the methodology we have previously used to test TRIM functionality, so I had to come up with a new way to test. I tested a couple of different methods, but ultimately I decided to go with the easiest one that can actually be used by anyone. The software is simply called trimcheck and it was made by a developer that goes by the name CyberShadow in GitHub. 

Trimcheck tests TRIM by creating a small, unique file and then deleting it. Next the program will check whether the data is still accessible by reading the raw LBA locations. If the data that is returned by the drive is all zeros, it has received the TRIM command and TRIM is functional.

    "It's just silly to take up to 50% hit in performance and only offer a few dollar savings because any educated buyer will gladly pay the extra few dollars for a substantially better drive."

    Exactly, and enthusiasts are usually the ones recommending products to other more casual users/buyers.

    Doesn't matter if it comes with gold-plating and platinum trim. It's still an OCZ, and they're the worst company in the SSD marketplace. They went broke for a reason, should've just let the company die peacefully. Toshiba is a good company, I hope they don't get dragged down to OCZ's level.

    It's not an OCZ, it's a Toshiba with OCZ branding.

    Three years later and this is what's being offered!!!!!

    From the OCZ earning conference call om May 1, 2012.

    "And further it’s our intent to continue to bring low cost technologies to market such as our TLC-based products, enabling this trend."

    The recent move into 1x nm lithography has been problematic for both MLC and TLC.

    Until others catch up with Samsung's V-NAND, it's only SSD I'm putting into builds now.

    Others catch up with V-NAND? Who the heck cares what they brand the NAND... 3D nand is a joke. There is no such thing as NAND that exists in the 2nd dimension lol. Plus, with Samsung you constantly have to deal with firmware update failures and crippled performance after 6 months. OCZ isn't great but they are disconnected from reality.

    Except V-NAND isn't just branding. There are multiple layers of NAND stacked on top of each other for much higher density. And as far as I'm aware, the only performance degradation issues have been with the 840 and 840 EVO series. Neither uses V-NAND, they're conventional TLC.

    In the past year I've deployed 30 SSD's at the company I work at. We use them for crunching cloud scanner data, so we're regularly filling then clearing entire 500gb drives and hitting them pretty hard while working with the datasets. 20 of those drives are Samsung 850 Evo's, they've all been running fine for about a year now. 4 of them are Crucial M550's, had one of them fail within a week but the RMA replacement drive is going well and all 4 are trucking along fine 6 months later.

    The other 6 were OCZ Arc 100's. All 6 failed within two months. RMA'd them all, assumed a bad batch. Serials on the replacement drives were two months newer, two of the 6 failed again within a couple of weeks. I've relegated the rest of the OCZ drives to unimportant tasks, it's just not worth the risk. I had high hopes after the Toshiba acquisition but it would take something extraordinary from me to trust an OCZ product again.

    Then Samsung's V-NAND is actually working and no company could touch or get near that technology including Intel/Micron. Samsung is on fire, as I am also impressed with their 14nm SoC in the S6.
  • StrangerGuy - Thursday, July 9, 2015 - link

    OCZ is such a toxic brand I wonder why Toshiba is daft enough to still keep it.

    So sad we can't get an update to the Intel 730 (735?) with 960GB size. Specifically NOT pci-e so a wider set of systems can use them. Clearly there are memory chips to do such a thing as shown here today...
