  • Phoinex Pro - low performance after use...


    I'm running a 60 GB Phoinex Pro connected to a MSI P45-motherboard. I have AHCI enabled (and Intel Rapid Storage-driver installed).

    I have tried to format the drive using hdparm. Should this operation just take a second? The feedback I get is the same as G.Skills guide. Performance seemed to went up a bit after this, but with some more (quite heavy) use, it goes down...

    I have updated the firmware.

    When looking at the benchmarks from G.Skill and some others I'm not close to the performance.

    In AS SSD I get 95MB/sec in seq. write perfomance. Also in Crystal Diskmark the performance is on the same level. But after some more use the write-speed goes down now to 60-65 MB/sec.

    I also have a Crucial C300. With the same use on the same system, I havn't so far seen any decrease in performance.

    From what I understood, SF-1200 SSD's should support both Trim and have a internal "garbage collection", so that the performance should stay good....

      Hi Falkend

      we have already noticed this issue and made sandforce awared.
      we hope the new firmware can solve this issue.
      this tool can make performance back.

        I've allready used hdparm to "reset" performance. But after a couple of runs to my tests, it's back to what I've seen earlier :-\

        Do the drive need idle-time to recover with trim/gc after heavy use, or should that be done "on the fly"?

          The Phoenix SSD should need idle-time to do the GC, and we are pushing Sandforce to improve this efficiency of its GC.
          We hope the later firmware update could solve it.
