Lacie unit is something I could use. However, their faq and manual state that a user may not replace a failed disk himself (will void warranty), but instead must contact reseller or Lacie. Review should mention this, and users that want capability of immediate swap should probably stay away from the product.

Hardrives are Matured Technology. Coming of Age right about Now.All Signals Are BUY.
For Vista & small hardware boot up glitches, dual bios, etc Seagate seems best answer, western is faster, yet Ultimate & high speed arn't common
There eXternals are good yet slower, although firewire800 is near 90 mb/sec, so acceptable. You probably have unused FW800 port or pins. Rest is step down, yet still very high quality stuff.& Simple & probably Non Activation threat.
