Performance vs. Transfer Size

ATTO is a great tool for quickly measuring performance at different transfer sizes. The v4 performs similarly to the m4 connected to SATA 3Gbps port in the read test but its write performance is poor between transfer sizes of 2KB and 64KB.

    For my HP635 notebook with AMD E450 chipset/platform. It turned out, that it is incompatible with notebook. Tried all kinds of tricks, from FW updates/upgrades... SSD just sometimes , not allways, didn't work properly at boot, showing boot sector problems and errors. The same SSD works very good in a desktop. Anyway, it is priced too high to be worth considering, since you can get Intel 330 or Samsung 830 for couple of euros more, but with much much higher speeds and with latest SATA speed.
    Oh, and before giving up I really spent many days in front of google, forums, support pages from HP and Crucial etc. What is funny is, that this very HP635 is stated as supportedfor a v4 128 on a Crucial web site...

    The SSD you bought is probably faulty and you should ask for replacement. Even if it's not faulty, it still doesn't work as specified. Reply

    So I bought a Crucial v4 128gb to use in my PC laptop. It was slower than the hdd, so I moved it to a desktop... still too slow... then finally as a last ditch effort, I threw into an old 2006 Mac Book Pro (A1150). Wow, it worked perfectly.

    Just goes to show. Old tech and old tech make a happy marriage. And don't get this if you have anything newer, just won't work right.
