Performance vs. Transfer Size

ATTO does a good job of showing us how sequential performance varies with transfer size. Most controllers optimize for commonly seen transfer sizes and neglect the rest. The optimization around 4KB, 8KB and 128KB transfers makes sense given that's what most workloads are bound by, but it's always important to understand how a drive performs across the entire gamut.

Based on IOmeter scores, the BP4 has pretty impressive sequential read performance at high IO sizes but I'm actually pretty surprised that the BP4 performs great across all transfer sizes. Write performance isn't as good but it's still average. As always, I tried to keep the graphs readable, you can find scores for all SSDs in Bench.

    i find it very annoying to see that modern ssds seem to consume as much power as 5400rpm mechanical HDD...Why no classic HDD listed as reference in power consumption chart ?

    Is there any talk about how compliant this is cross-platform?

    Samsung had firmware issues that pretty much required Windows to update. Do these play nicely with *nix and Mac?

    At this time we have had no issues on any platform with the current FW 4.6.

    I have a 128 GB MyDigitalSSD that was purchased in October-2012. Its performed with no issues .. I suspect battery performance might not be ideal, or speed either.. I beat up on this system every day.. use it with Linux on my Lenovo T430s. Reading this review wants me to upgrade - especially since I did not have any issues with this manufacturer.. The low price helps too.
