Can you do RAID 1 configuration on the T60?

Just curious since you can replace the CD/DVD drive with a 2nd HD.

With a software controller you might be able to set something like that up; although you don't need somethig like RAID 1 if you have imaging/backup software. There was a thread here awhile back about this. No really need for it as you can sync up the HDDs manually.
You might also be able to go for RAID 0 instead, which isn't an actual redundant setup. Instead, RAID 0 spreads the data across the disks, and syncs them on read/write ops; thereby attaining faster operation rates.

Correct me if I am wrong, but with RAID 0, you can't access the data if one HDD is absent (in case you want to use your optical drive).
Besides, you can't place the system/boot partition on a RAID 0 partition.

correct. when one HDD fails or is removed from a RAID0 array teh entire array fails.

huh? of course you can!

Of course you can't !!!
As a reminder, we are talking about SOFTWARE RAID (with no hardware RAID controllers).
You can't place system/boot partitions on a software RAID0 (MS Terminology: stripe set).
Think logically, the system needs to load the RAID driver before accessing the data (which resides on the stripe set). This is like locking a safe with its key inside it !!!

oh.
well, in general, you can... which is what i thought you were saying. my bad. I didnt know that windows striping was actually called RAID0, since it doesnt work exactly like RAID0 does... sure, it makes two drives act as one, but it doenst store data the same way afaik.
