Disk storage is notoriously fickle. One minute your drive is humming happily, and the next it's screaming like a banshee and trying to turn into a lathe - or simply dies. Whatever the issue, at that point the unprepared probably will start swearing, invoking the gods of hardware, sacrificing chickens and, eventually, drinking heavily. We did.
A few weeks ago we were testing some software on our Apple G5 and we were running out of disk space. It was urgent we get the project wrapped up.
We remembered that we'd been sent a really cool storage subsystem that was still in its box, and we suddenly felt guilty, because the product was one of those review projects we'd planned to tackle - over a year ago.
We figured this was a good time to try the device, a Kano SureVault800-360. The SureVault is a 360GB RAID 5 storage system (priced at $1,139) that supports Firewire 800, Firewire 400 and USB 2.0. The device works with Windows and Macintosh PCs (it is formatted by default for Macintosh).
Because the SureVault supported RAID 5 it was just what we were after; the data we needed to move off the Mac was our photo collection, which, you will remember from previous BackSpin columns, is rather large (it's now up to around 16,500 images totaling around 20GB).
RAID 5, we're sure you remember, is where data is striped across several drives at block level, with parity also being copied across the drives. In the case of a single drive failing, the complete data set can be rebuilt without data loss. Because most of our photos are irreplaceable we figured this was an excellent solution. What could go wrong?
We unpacked the SureVault, gave the manual the cursory once-over, plugged in the power, connected it to the G5 via the Firewire 800 port, switched it on and, lo and behold, the SureVault worked! Amazing. The SureVault over Firewire 800 is really fast, but the fans are a little noisy.
We moved the photos off the G5's internal drive onto the SureVault, and everything was fine - until a few days later.
The Firewire cable connected to the SureVault was pressed against the wall, and suddenly the SureVault didn't work. The pressure of the cable against the wall had stressed the connectors on the subsystem's input/output board and the Firewire connector popped off (the latest SureVault units are engineered to prevent this problem).
