ATTO - Transfer Size vs Performance

ATTO is a handy tool for quickly measuring performance across various transfer sizes and it's also freeware that can easily be run by the end-user.

OCZ Trion 100

The 240 GB drive seems to have an issue when it comes to writes here, showing variable performance across any transfer size due to the SLC buffer being filled and emptied during the process.

AS-SSD Incompressible Sequential Performance

Similar to ATTO, AS-SSD is freeware as well and uses incompressible data for all of its transfers, making it a valuable tool when testing drives with built-in compression engines (e.g. SandForce).

Incompressible Sequential Read Performance

Incompressible Sequential Write Performance

When an SSD vendor quotes peak read and write speeds, these are the numbers typically referred to, despite its supposed relevance to regular workloads.

    I always wondered why no other company bid on the OCZ bankruptcy assets. Toshiba was the only bidder. Now we learn............

    "Toshiba president Hisao Tanaka and his predecessor Norio Sasaki resigned on Tuesday over a $1.2 billion accounting scandal blamed on management's overzealous pursuit of profits"

    "It has been revealed that there has been inappropriate accounting going on for a long time, and we deeply apologise for causing this serious trouble for shareholders and other stakeholders," said a company statement.

    I thought Toshiba acquired OCZ for the expertise. Instead, the only thing they seem to be using is the brand label - a brand connoting unreliability and deceitfulness. High-fives upper management!

    Thanks for another great review Kristian. It is always good to see the full spectrum of what exists in the SSD space, and let the results do the talking.

    I'm still not seeing major advantages over the Crucial MX100 512GB in many cases when it comes to high capacity, great performance, and good value.

    I expect more from OCZ when I see that name. My OCZ DDR memory sticks are a reminder of that bygone era.

    Hi folks. Now that the price of this drive has dropped to $279 its looking more attractive as a budget drive. Do we think that there is a possibility that firmware updates would improve its performance over time? Thanks.

    New firmware (11.2) was just released which addresses the high latency issues on heavy loads, which should improve performance (and possibly power consumption as well) in the "The Destroyer" section of these tests where it performed particularly badly.

    The firmware version format seen on these drives is pretty obviously a Phison S10 controller, so hopefully OCZ can apply their expertise at low latency firmware design from the Barefoot-based products to this architecture and hopefully Phison-based products in general. Barefoot-based drives unfortunately can't really be recommend in general for mobile use because of their high power consumption, so this teaming of OCZ and Phison has some potential (like Intel and Sandforce in their SSD products) for improving the market in general.
