  1. Help?
  2. As far I have seen, is that the 30GB would be cut down to the smallest drive. Is that true?
  3. Hi

    Yes. To run a Raid 0, the information is theoretically split equally between the two drives. This means that drive sizes have to be equal. You would get a 30GB rain drive.
  4. with a 16GB and 30GB drives here's your raid options and max logical disk size:
    raid 0: 30GB
    raid 1: 16GB
    JBOD: 46GB
  5. Don't raid SSDs. With current controllers and firmware, it knocks out the functioning of the TRIM command and the speed of the drives degrades over time.

    That's a problem of the past.

    i have 2 WD 256GB SSD's. individually they benchmark 240MB/s seq read and 180MB/s seq write. but in RADI 0 they do 385MB/s and 260MB/s. clearly the loss of TRIM was more than overcome.

    To Branden and Tulx both: cool! Any idea why it works? Is Garbage Collection good enough to compensate? I'm pretty sure that if the TRIM / RAID issue had been overcome I would have read about it.

    i don't know enough about the inner workings of RAID or TRIM or garbage collection to be able to speculate why it works. i had no idea myself how RAID 0, JBOD, and leaving them as individual drives would compare so i benchmarked all scenarios, turns out RAID 0 was fastest so i stuck with it.
  10. First - The effectiveness of CG is highly dependent on three factors:
    (a) The Controller in the SSD, The marvel being the worst.
    (b) The amount of free space
    (c) How the user interface (uses) the SSD

    Some comments on raid0
    - Raid0 improves sequencial read/writes around 50/60% as branden pointed out on his. This provides a big benifit when working with large files. Does very little to improve small file random read/writes and no improvement in access time. These two factors are the most important in boot time and program load. - branden, how much did these two factor improve on your raid0 setup.

    My 2 Cents:
    - Raid0 may be the choice when you have a pair of larger capacity drives and can leave a fair amount unused. My personal oppion is that with 2 very small drives, Not recommended, unless you plan on using them as a data drive and leave 20% of the avalable space free. (2 x 16 - .2 x 32 = 26 gigs Dec, so really less - TOO SMALLL for a boot drive + no trim) Vs a 16 - 10% + a 30 - 10% as two seperate drives for data with trim.
