    Hey Yall im getting two 840 256 pros with some icydocks to put in my Mac Pro, Temporary "for about 6 months then moved to my pc gaming rig". Thats why im getting pros to later use in my sata III pc. I know all about the sata II limitations in the mac pro and i also know about sonnet tempos and pcie cards "dont want". The Question is if i set up two 840 pros in raid 0 on my mac pro what block size should i choose? i have about 5000 pictures in iphoto at about 3mb a piece and about 10000 songs in itunes. Im not doing any video editing or photo editing im just a average user with a 12 core :D. So what block size should i pick? also is using softraid the only way to get trim on these ssd in raid 0? also i shouldnt get to much degradation on the raid 0 speeds rite if i dont have trim? i am expecting 500 read and write on a sata II raid 0 setup throughout the 6 months, rite?

    • I dunno.
    • Double negative, and, I dunno.
    • 590MB/s is more like it for sustained sequential R/W of large files and 540MB/s in something like the BlackMagic bencher.

    If you are looking for some cool mount adapter alternatives to the IcyDock (which are pretty good) ... I found some eBay Ice Pack recycled "WD VelociRaptor" drive mounts awhile back which work great.

    They are the 3.5" SATA "shell" that the 10Krpm Velociraptor 2.5" disks are mounted in to provide head sink cooling. Standard 2.5" SSDs will mount in them, and then the shell will mount as a standard 3.5" disk on the Mac Pro drive sleds with the SATA connector in the aligned location. The large heatsink fins are overkill for a SSD, but they sure look neat, provide cooling, and were cheaper than the IcyDocks.

    Looks like they may have gone up in price ... I think I paid around $10 each for mine.
