    Hi everyone,

    I'm thinking of purchasing the new sony Z-1190 laptop. Some of the options have only one drive (say 128GB X 1, or 256 X 1) but still supposedly have raid 0. How is this possible (I thought that more than one drive was needed)?

    Thanks!

    P.S. Would there be a performance difference between the 256X1 or the 192 (64X1 + 128X1)?

    Thanks!

    Maybe they mean they have the capability to be in a RAID 0 configuration. And I really don't think there should be a difference in speeds between 256 or 192 configuration, seeing as how they're the same brand of drive with the same controller board.

    One drive on each side of the card. 128GB x 1 means 64GB on each side, which means there are two drives.

    192GB means there are three drives of 64GB each. I was hoping someone would respond to my question whether or not the Z has a capability to setting the drives up as RAID 1 + standalone or as RAID 5 if TRIM can be enabled.

    Interesting! I see why Sony does it now. SSD prices.

    Interesting... Does that mean with the 192GB I could have three drives together in a raid 0 configuration? It would be pretty fast aright, but I would by worried about failure. The option to go with raid 5 would be wonderful.

    Out of the box only JBOD and Raid 0 are avaliable...no 1, 5, etc

    According to ZoinksS2k you can't set up JBOD array. Raid 0 or separate drives are the only options.

    As far as I know, JBOD is not "exactly" separate drivers. It abstracts both drives behind a single drive letter, but does not strip writes/reads and will not split files between the two drivers, so you won't get any performance improvement and if one drive fails the other drive is still usable.

    Alright. For 3 drives, what about RAID 0 for first and second, then a separate with TRIM for the third. Would that be possible to configure? I think that's what I would likely do when my Z arrives.

    But for those who want maximize performance by leaving some free space on each drive JBOD isn't a good idea.

    The only RAID option is 0. And if two drives are going to be in RAID 0, that means all 3 must be controlled by the RAID adapter. Which means creating a 1-drive RAID 0 array, which as far as I've read is still treated by the system as RAID and won't get trim support.
