    yes, you can use the ssd's in raid 0 and have to regular non raid HDDs connected (you can also have those 2 hdds in a raid)
  3. Yes you can. But why do you want to?
  4. Thanks for the answers. Now I'm learning that RAID 0 does not work so well with SSD.

    That's why I asked 'why'...:)
  6. It also doesn't provide any tangible benefits on the desktop....never has .... except for some very highly specialized applications.
  7. Its not that Raid doesn't work well with SSD's, its just that if you have a Sata 3 system, you wont notice any performance increases in real applications (you will get better scores in benchmarks though).

    However, that doesn't mean its not good. Raid 0 will let you combine, say, 2 128gb ssds to form a 250gb drive to use, as opposed to 2 small 128 drives.

    If you have a older sata 2 system, raid will make a noticeable improvement in speeds, since an SATA 2 provies only ~250mb/s bandwidth and a good SSD will be bottlenecked by that.

    And 2 x 128 independent drives gives exactly the same space as 2 x 128 drives in RAID0. But without the RAID overhead, and possibility of RAID array failure.

    One of the reasons I thought about using it was that my motherboard only supports SATA II, and I wanted the increase in speed. Maybe it is not worth the possible problems.

    There are no problems with it. I can tell you from personal experience, not just common sense which you also seem to have, that you will get faster speeds.

    I am running 2 Samsung 830 SSDs in raid 0 on my X58 mobo. I get 500mb/s read/write. I have also tried using a single one, and its not anywhere near as fast. my setup is comparable to that of a 250gb Samsung 840 pro running on a new sata 3 system.

    Also regarding failures : good SSD's are much more reliable then old HDDs and wont fail for alteast 5 years. Plus its an invalid argument to say 2 SSDs in raid is twice as likely to fail as 2 separate SSDs. if one drive fails you will still lose data, regardless of raid or not. This argument is only valid when comparing a single 250gb drive vs 2 128gb drives.

    If you do decide to get a single 250gb drive, it will be heavily bottlenecked at 250mb/s and yes the difference IS noticeable.

    In a Sata 2 system with SSD's raid is your best friend.
