S20 Hard drive - maximum size?

[Ian_A]

Hi Folks - I'd like to fit 2x 2TB drives in my S20, but our IT procurement department says the computer will only support 1TB drives maximum. Is this right?

2TB drives are supported.

Are you using any sort of RAID with the 2x2TB config?  There's a limitation (BIOS) that the bootable partition size can't go above 2.2TB.  So 2x2TB would be OK with a mirrored RAID1 config, but not OK with a striped RAID0 config.  This only applies to the bootable partition so if you're strictly doing a data RAID, you would be OK with either.

Thank you for your prompt response, I now have the drives on order.

I'll be using them for storing and editing video data - .avi files of around 10GB in size. It's my intention to use one drive as a source and render to the other, avoiding reading and writing to the same disk as I have to do currently with the single 500GB drive fitted.

Drives arrived yesterday and were fitted this morning. They're SATA III units, and they work fine.
