An fast, moderate-sized and extraordinarily cheap drive.
Refurbished, but these seem to be in good shape. Don't expect the intel manufacturer's warranty to have much, if any, time left. You're leaning on newegg, and then perhaps your credit card's insurance policy, if it has one.
External eSATA and internal SATA expansion card.
A tool-free dock. Plug a hard drive in like a floppy. Does not support hot swapping, but doesn't need to. Turn it off, plug in a hard drive, turn it on.
Has two front-facing IDE ports.
This is an eSATA dual hdd docking station.
Purchased so my Raspberry Pi and then CubieTruck could have good storage.
Has both a USB and an EIDE connector. I bought it for the latter.
Using two hard drives simultaneously requires a USB port which has "port duplication", a feature which, sadly, my motherboard didn't have.
