Does these numbers suck for eSata?

    I'm not familiar with eSata but I can see these numbers for the X-25M aren't the same as when the drive is internal so I suspect that because the enclosures are cheap and not Oxford 924 that that would be the reason and not the AEK card itself.

    I will probably end up buying an Oyen Digital enclosure just for comparison

    These two attachments are

    X-25M in a RocketFish enclosure over eSata
    320 gb drive in a RocketFish enclosure over eSata

    I suspect these numbers show that I'm not getting the full benefit of eSata because of the cheap enclosures.

    Is your eSATA adapter PCI Express based or USB based?

    Looks like it's maxing out around 1 gbps. Is the eSATA controller 1.5 gbps or 3 gbps? How about your drives?

    right now I only have one type of enclosure that supports eSata and it's a cheap RocketFish enclosure that's not Oxford chipset.

    One of the drives in the enclosure is the Intel X-25M 80 GB Solid State Disk.

    The package of the BC338 card says on the back

    "Support SATA II specification with transfer rate up to 3 Gb/s"

    If I had eSata enclosure that used Oxford 924 I'd then be able to tell if it was the enclosure or the card that's the limiting factor but with the X-25M, it most likely isn't the drive.

    Have the same card; I get around those speeds on a standard HDD. Don't have an external SSD to test with.
