    Default 32GB RunCore 2.5" Pro IV SATA performance degradation

    Hi, recently I bought a 32GB RunCore 2.5" Pro IV SATA , first time I did some benchmarks and the perfomance was realy good
    In cristal disk mark i get about 190Mb/s sequencial read and 130Mb/s for sequencial write, after somdays of use I did the same benchmarks and only get about 117Mb/s read and about 33Mb/s write ! Same results with ATTO, the write speed is about 30-40Mb/s max.

    But in HD tach i get average of 180Mb/s reading.

    Ive clone this disk to a patriot V2 ssd 32gb and did the same tests resulting in about 150Mb read and 92Mb/s write in cristal disk mark

    Any ideia why im getting this 30-40Mb max in write speed?

    Tanks for any help

    Do you know which firmware version you have?

    For best performance you want:

    - the partitions aligned to a 512kB boundary. A fresh Windows 7 installation involving partitioning the SSD would have done that for you, aligning to a 1MB boundary.

    - if you have firmware 1571/0.1, ensure wiper.exe has been ran. Firmware 1819 doesn't need it as it provides trim support.

    Hi,thanks for replying
    My firmware is 1819

    I dont understand why performance is now a lot slower in benchmarks than it was some days ago when I clone all data from my 32gb patriot v2 ssd.
    First tests the run core run the performance as i expected 190Mb/s read and 130Mb/s-140Mb/s write , superior to the patriot ssd, now it has a poor 119 read and 33 write.
    The same tests on patriot show me that the performance of the patriot ssd is constant in time, the results of benchmarks are always the same as I did some months ago, but the run core had this degradation with about 5days of use :/

    I will make a fresh install of windows XP and full format to see if this results are the same than I post the results.

    Hope not to be disapointed with this run core that is one of the best for the price.

    OK - you are running XP, so must do a manual wiper.exe run for garbage collection. OCZ recommend running it once every 2-3 days. That will restore the write performance. If you were running Windows 7 it would do automatic trim garbage collection for you.
