Protection if one drive decides to die.

i had nevar lost a drive,. hehe

Lucky man :P

yes,. but i guess maybe its because my pc is almost always on,. no cooling dow and heating up,. maybe dunno,.

I had a 200GB drive die in parents' computer.  Was just being used fine, then suddenly the computer crashed and HDD refused the spin up later on.
Also, all the posts about people complaining about drives dying...

Honestly, I don't think it happens often at all, but when it does happen...

Most recent mobos only seem to have 1 IDE channel.

Actually, I might can the RAID5 idea.  Stick all the stuff I've got a copy on DVD onto the 1.5TB drive, and stuff I don't have on DVD onto the 2TB RAID1 mirror.
Alternatively, run 1.5TB and other 2TBs in RAID5 (3TB) and the extra .5TB of the 2TB drives in RAID0 (1TB) or RAID1 (.5TB), which gives similar total space.  Don't think the onboard RAID controller can do this, and possibly more difficult to restore in the case of a failure.  Wonder if Windows' software RAID can handle it.

Damn, they had a deal for 2x 2TB Seagate 5900rpm drives about 2 days ago, for $220 which includes shipping.  Could've saved another $30 >_>

From the online tracking system, it seems that the parcel was sent, but since I'm not at home, redirected to my "local" post office.  Which totally sucks, cause I go by various post offices every day, but not this "local" one, which is like, at least 3km away with no public transport going from home directly to there (ie, need to go bus » train » bus to get there).
Hope it can be transferable to another post office, but I'm not hopeful.

EDIT: double you tee eff?  There's like a post office about 1km away, 'sif the one they sent it to is my "local" PO!

Had to pay $5.50 for a transfer.  How lame.

Anyway, it's in two big boxes, wrapped in black plastic, which is relieving since it means there's lots of padding.  That's, a thick cardboard box, with foam all around inside, then two layers of bubble wrap (one of them being particularly thick).

The WD Green drives apparently don't support WD's TLER, and for portability, I decided to stick them in software RAID1, using Windows dynamic disks, rather than the on-board Intel "fakeraid".
Rebuilding a broken RAID1 using Windows Disk Management doesn't look terribly nice though... >_>
Will also need to see if Linux can recognise Windows dynamic disks.

As the two drives are from the same batch, I decided to try and simulate some wear on one of them, by unplugging a drive, and then performing a full format on the other.  Hopefully this reduces any potential correlation of random failures between the drives.
Also am hoping the software RAID isn't affected by the lack of TLER.

i am not looking forward to install raid,. O_o

can't they make some sort of hardware HD raid disk,. a hd with a double disk wich auto back-ups all data,.. basicly a raid system without a second drive,.

Yeah, you can get external drives like that.

Otherwise, it actually might not be a good idea.  Disks produced in the same batch probably have a relatively higher correlation of failures.
Besides, you have the problem of replacing a disk when one does fail.
