let's keep practical here please. The question is whether you can use
SATA RAID as a reasonable HD failure protection system or not.
Can a Raid1 on two HD, say less than 500Gb, be consider as a good
protection against HD failure? It still seems to be for me. (I
consider recov
SATA drives just aint built with the same resiliency as SCSI, hence
the massive difference in cost.
So..as an example, the Hitachi 500G 7K500 drive has a non recoverable
bitrate of 1 in 10^14th. The 10K300 FCAL (basically scsi) drive is 1
in 10^16th. Those two zeros mean a _lot_.
I removed a
well, you mean on RAID5 then, coz there's probably no math in
reconstructing a RAID1.
Why would the math on SATA be less reliable than on SCSI???
Where d'you read that anyway??

Did you know that most "oh my god" RAID failures happen during the

.Especially on SATA as the non-recoverable-bit-error math is so much
easier to run into.
I think..that on a 500G drive, there are enough bits to read/write
that mathematically you could run into a

Sounds like you have one of those 'fake' raid controllers
(http://linux-ata.org/faq-sata-raid.html ), where its software raid with
a hook into the bios so its bootable, while the work is done in
software. This isnt supported by Freebsd (the fake raid 1 is supported
by the ataraid driver for many ch
