    I've seen a cheap deal for some SAS drives that are bigger in capacity
    and faster than the current SATA drives

    Otherwise I will have to invest in a enterprise grade server case to
    support SAS drives properly.


    I don't know the answer to your question, but is it possible the
    awkwardness of using these drives explains their cheapness?

    I had wondered about that....

    after a bit of digging around, it would appear that SAS backplane cages
    are available......

    Some of these cages are for LFF SAS drives, some are for SFF SAS drives
    and they seem to be able to hold either 4 or 8 drives....

    My Tower case has 6 removable blanking plates for up to 6 5.25 inch
    drives (like CD rom /DVD rom) so I wonder if one of these SAS backplane
    cages could fit?

    AN old G7 Microserver? I'm seeing them parted out for their backplanes.

    HP Proliant Microserver Gen 7 Backplane Mini SAS SFF-8087 to SATA / SAS https://www.ebay.co.uk/itm/304564660421

    The cabling is SAS, however the on-motherboard controller is not. That
    can be fixed by adding a SAS controller. They are cheap (some below
    £20!) and currently I'm searching recommendations.

    The board end connector on the cable is "SFF-8087" and for me this looks
    a candidate (from https://n40l.fandom.com/wiki/Raid)

    HP Smart Array P212 ZM

    I have a stack of 3.5" SAS drives acquired after completing buy-it-now
    on ebay, and then finding my foot in my mouth - I actually needed 2.5"

    So mine will be a box to totally backup my QNAP NAS, which did not amuse
    me last week when after restarting it, it decided to unlink the home
    directory for all authenticated users. This causing me to imagine the
    worse for most of my profile held stuff. It didn't help, that I was
    dealing with a disk failure and rebuilding the new drive at the same time.

    These are the two controllers I have:

    Hello all,

    I have a domestic personal PC in a Tower case that has two Adaptec
    7805T controllers. These controllers can work with either SATA or SAS
    drives.

    I currently use SATA drives on the Adaptec 7805 cards and this is
    being used as a NAS.

    I've seen a cheap deal for some SAS drives that are bigger in capacity
    and faster than the current SATA drives

    I understand that SATA drives have 2 seperate connectors for power and
    data whereas on SAS drives they are one physical connector that
    carries both power and data.

    Now the Adaptec cards clearly only have data connecotrs. Typically SAS
    drives are used with a SAS backplane in enterprise grade servers.

    So can I get away with SAS breakout cables like these in order to use
    my exisiting case and Adaptec 7805 cards with SAS drives or am I
    overlooking something?

    Sometrhing like this:

    https://www.newegg.com/3ware-cbl-sas8087ocf-06m/p/N82E16816116091

    (there are reports of SAS drives not being recognised consistently
    where an alternative method is used to a SAS backplane)

    Otherwise I will have to invest in a enterprise grade server case to
    support SAS drives properly.

    I do not if this helps, I strip SAS controllors from dell workstations
    and sell them on E bay.

    This is what with 12GB/s speed ones look like and have cables for, hope
    it helps.
