    More details required: what are the SSDs, how are they connected to the Pis, are you looking to boot directly from the SSDs with no microSD card installed?

    Assuming the answers are: USB flash drives that you've checked can cope with being boot devices, via USB, and yes, in that order, you'll first need to check your Pi models can do USB boot (only the Pi 3B/B+/A+ and Pi 2B v1.2 can, no other models) and enable the option if you're on anything other than a Pi 3B+/A+. Then it's just a case of cloning the microSD onto the USB flash drive: if you're running Linux, that's as simple as:
    Code:
    $ dd if=/dev/sdX of=/dev/sdY
    Where X is the microSD and Y is the USB. I assume Windows can do something similar, either directly or using third-party software. The important thing is you need to clone the partitions as well as the data; dragging and dropping in Windows Explorer ain't going to do the trick.

    Frankly, though, I'd probably ditch the idea of using fragile USB sticks as boot devices and either use slightly-less-fragile microSD cards or - and this is by far the best option - network boot to do away with the need for local storage at all.

    There's no reason it shouldn't be able to boot from that, but with the proviso I've never tried that particular model of SATA adapter before.
    I've got a Pi Blu-tack'd to my monitor which acts as secondary DHCP server and lights up when my doorbell goes off, and it's had the same 4GB Transcend SDHC card in it since... February 2012? If it's writes that are killing 'em, look into how big the SETI stuff gets - you might find you can get away with sticking it in tmpfs and having no writes to the card at all (with the proviso that if there's a crash you'll lose any unsubmitted workunits.)

    i dont think it's just seti thats killing them, i do other stuff on them as well like update every month, run a mumble, terraria servers (not while seti runs and not on all of them)
