Anybody has any experience with these relatively new one Terabyte (1TB) hard drives that are capable of RAID 0 and 1 configs?
Apparently, from what I have read in CNET's user reviews, it's a crap shoot.
Most have had bad experiences, having returned units more than once; with the heat generated being an issue or simply getting it to stay mounted when used via FireWire (which is faster for those drives than USB even though theoretically USB 2 is faster than FireWire 400).
I was thinking of the advantage of the instantaneous and automatic backup that the RAID 1 configuration provides.
But then I realized that it may not always be good.
For example, if I accidentally change and save a file, it will be written that way to both physical drives.
With the backup scheme that I have now (manual, using CasperXP) I would still have the ability to reclaim the previous version of the file from one of my backup drives.
BTW, since having the boot (C) drive fail would be very bad (cannot boot until you replace it and may have to reinstall the OS), six months ago, when my PC turned 5 years old, I replaced the original internal 80GB drive with TWO identical WD 120GB drives with 4 times the cache memory of the original AND made the second a pseudo-mirror of the first, from which I can boot if needed.
Using the Ultimate Boot CD, I can choose from what internal drive to boot from. (Windows XP cannot boot from an external drive. And probably the same for Vista.)
CasperXP duplicates the C boot drive to the second internal, including the boot sectors (otherwise booting from the secondary drive wouldn't work).
So for now I think I'm going to wait for the 1TB drives to become more reliable (and less expensive) and use one as a secondary backup for the really important stuff (like my music LIB)
I still find it hard to fill 160GB of hard disk memory. Now 1 TB of RAM would be great. No need for hard disks. I think it will come to that in a few years. I expected the 1 TB hard drives to have less trouble. oh well
