ATTO - Transfer Size vs Performance

ATTO provides a quick and easy test of performance over a range of block sizes, which makes it a good overview of performance. It illustrates quite clearly how performance plateaus as transfer size increases, with reads bumping up against the limits of SATA but writes being limited by the speed of the flash itself.

Any drives that perform transparent compression will perform much worse on this test than the Iometer tests. The SandForce controllers that relied heavily on compression are much less popular (having been largely displaced by controllers from Silicon Motion, Marvell, and Phison), but this in still an important metric to keep in the suite. Many real-world sources of bulk data (such as encoded video) are already heavily compressed and cannot benefit from any attempts at further compression.

    Yet another new SSD article on AT that ends up showing how it gets destroyed by Samsung in overall specs/price.

    Actually the Crucial BX100 is a better choice looking at the scores.

    Nope, not to note it isn't even present on many screens and MX200 is a different product.

    The BX series is better bang for the buck, you won't notice the speed difference with the popular samsung drives.

    im shopping for new 240GB+ ssd. looks like BX100 is the way to go rite?

    I rather go with AMD Radeon R7 series. Its one of the highly rated high drives in the market (see http://www.consumerrunner.com/top-10-best-hard-dri... for example)

    Assuming this is a low-end drive i.e. cheaper than the 850 pro, it looks like it outperforms the 850 evo mSata pretty much across the board, getting close to crucial's BX100.

    As an owner of 2x840 EVO and 2xPlextor, I can tell you the Samsung's bug was a major disappointment. Read performance after months simply sucks and I had to patch the firmware 2-3 times and regularly "manually" freshen the data with the samsung tool. I have way more confidence in the Plextor firmware. Never again Samsung.

    ...yet another SSD article on AT that focuses on the pointlessness of non-real world benchmarks. Readers will leave this article without having a clue what boot time differences to expect between drives, or any other metric. I've been saying this for years. HardOCP finally caught on. http://tinyurl.com/pvyzmau

    What is the purpose of reviewing SATA SSD drives? Anyone in the market for a drive should either buy a spinning HDD for storage or a PCIe for speed.
