    So first off, who here has an SSD in the empty optical bay? Do you suggest I do the same?

    Also, I have a question about OWCs drives. On their site, they say this:
    Ultra-efficient Block Management & Wear Leveling
    Prevents write speed degradation commonly experienced by other brands' SSD.

    I am wondering how they do this without OS X supporting the TRIM command. If it is something in the SandForce controller, does that mean the OCZ Vertex 2 will be the same?

    Thanks!

    The optical bay actually fits four 2.5"s :eek:

    Awesome thanks!

    Physically yes, but more is required to get all 4 to work properly.

    That site didn't really say anything about using the drive under OS X, which doesn't support TRIM, only windows 7. I am still curious as to how OWC says their SSDs don't degrade and if it is the same as the OCZ Vertext 2.

    Trim wouldn't be supported under a RAID anyway (software or hardware implementation), even if it was supported for single drives.

    So does anyone know how the OWC SSD doesn't degrade and if they are both the same?

    OCZ has 3.5" versions of various ssd "colossus model sizes. Hopefully Apple will use drives based on these without the need for adaptors.

    The OWC Mercury SSDs use the Sandforce controller, which apparently obviates the need for TRIM (as I understand it).

    If it's only because of the Sandforce controller, does that mean the OCZ Vertex 2 also obviates the need for TRIM?

    I think the Vertex also uses the Sandforce controller, but you might want to confirm with OCZ first.

    Here's my performance comparison of the OWC SSD, eSATA, FW800 and FW400 in my hackintosh.

    The article earlier said that it too uses the Sandforce controller. Is it the controller that makes the OWC SSD not degrade over time? If so then that would mean the OCZ one doesn't either, correct?

    Yes, that's my understanding. The Sandforce controller on the SSD is what does the job of TRIM, so it prevents the degradation of the drive.

    Very interesting. So would it be better to get an OCZ Vertex 2 if the prices are about the same because it comes with a 3.5" adapter?
