Test Procedure

In an effort to really stress the flash SSDs, we ran the following cycle on all drives:

1st cycle

  • h2benchw sequential read/write test
  • IOMeter fileserver, database, webserver, workstation profile I/O test

2nd cycle

  • h2benchw sequential read/write test
  • IOMeter fileserver, database, webserver, workstation profile I/O test

3rd cycle

  • h2benchw sequential read/write test
  • IOMeter fileserver, database, webserver, workstation profile I/O test

4th cycle

  • h2benchw sequential read/write test

5th cycle

  • h2benchw sequential read/write test

6th cycle

  • h2benchw sequential read/write test

We decided to run the sequential h2benchw test and immediately switch to I/O loads three times in a row, so the drives would have to switch from maximum throughput to maximum I/O performance repeatedly. Then we ran three additional h2benchw tests to see if and when the flash SSDs returned to their initial performance levels.

    What's the level of overhead needed to get the most of of these drives? Buy a 80Gb drive but only ever use 60Gb? It's its own swap file.

    Think overly fair view, yet ALL parties have made quite effort to get SSD workable. in Stating SSD IS Fast, Faster than Best HDD, One problem, There Seems to Be Disparity Between testing teams on How to Measure SSD Performance ACURATELY. Some Suggest NO Standard Test Exist today Except in most Primitive mundane way.Windows Has NO SSD Optimazations, PERIOD. .

    SSD Might State Faster Speeds, yet Are those speeds true? Maybe NOT, Seems ALL Numbers Fall apart quickly, Indeed SSD Drive itself IS Being OverTaxed & Fails way Too soon.

    Its NO Time To Recommend SSD For Any Home Use.

    I saw these issues with my 160GB X25-M I received last week. I was about to return it, as my computer was stuttering like my old OCZ Core V2 128GB did. But I did my homework, and found the firmware update. Min write speeds went up by 10x.

    But I could sense all was not completely well, even though I had updated to F/W 8820, and apparently there is a small issue with Vista. I updated my Intel Storage Manager software, and now it is perfect.


    I'd buy the SLC device if I had my chance again, but that would assume 160GB+ X25-E existed.

    This has been one upgrade that you will notice easily.

    Basicly, SSD field Best is SSD Card 16x pci-e right now. its fast evolving field, forget old stuff. its really NO good. controllers are still forthcoming, with just two know ssd cards available at fantastic prices that claim random read/write up to 500 mb/s or even more. from there its steepe drop to about ~20 mb/s random speeds, Many do less than mb/s, WHICH IS TERRIBLE. best advice:WAIT UNTIL LATE FALL '9 till you make such pricey & poor decision as todays will bring.
