Lacie S2S upgrading over 5tb?

[waynestewart]

A while ago I picked up a Lacie S2S 5 drive RAID array. It was originally meant to connect to a Lacie eSATA card but worked well with a USB 3.0 adapter. Unfortunately 2.5tb was way too small to be useful. At the time I had some 1tb drives and upgraded to 5tb, still a little small. Just yesterday I ended up with a number of 2tb drives so I tried upgrading the S2S. No luck with that. So has anyone been able to get a S2S over 5tb?

I hadn't heard of this device before, really neat.

Some SATA controllers, RAID controllers especially, have trouble with disks over a certain size. The Dell PERC6/i can handle up to 2TB disks and HP had a disk shelf that accepted SATA disks and used SCSI externally to connect to a host machine, and that device accepted up to 250GB disks, to present a 2TB volume to the host.

So, my guess here is 1TB is the maximum size the controller in this device supports.

Unfortunately, if I had to guess based on the datasheet and manual, it's probably not really possible to circumvent that or avoid that controller by replacing it with something better, but I haven't pulled one of these apart. You might be able to pull the backplane off and wire it up to a newer sata expander or to five usb/sata bridgeboards or to five esata ports on some cards, for example.

If I had a second one it might get interesting. I've got a Lacie eSATA hub.
