A few raid questions (2x80gb SATA II)

post #1 of 10
Thread Starter 
Hi all!

Currently, I've got one 80gb IDE HD 7200 rpm and another 40 gb IDE too 5200 rpm, this last one is dying.

My question is, If I buy 2x80(IN RAID 0, thanks cyrixMII300) gb SATA II, lets say, 150 GB in total (cause of the real size) and lets say a suden shutdown happens, what happens? is it that difficult to recover? or I'll lose a few files at most(like 1hd)? any information about security, fiability which you can tell me will be apreciated.

Those HD will be arround 60 usd each one, thats the best price I can get here in mexico.

Thanks a lot.

question is are u going to put the two new 80Gb on RAID 0 or RAID 1? if RAID 1, which is mirroring then ur data will still be intact until the last moment of dying. but only between the two drives. plz elaborate more before i proceed.

RAID 0 is only for stripping which means u will not have any backing up of data. u might see a slight improvement in performance but i think thats about it. the likelihood of losing data during power failure and drive failure would be the same as normal drives if not more.

If you keep all your data in one partition then yes you will lose it if its not backed up. What I do is put my OS and any system critical stuff in a single partition then anything else goes in another partition that way If I have data corruption like last week due to a dusty sata port corrupting windows then all I do is need to go in and repair or reinstall windows. If you are gonna run raid-0 then I would highly recommend a firm backup strategy of any very important info or you can just make an ISO of your harddrive and save it onto a cd. Ive been running a Raid-0 array for about 2 or 3 months now with no issues what so ever except the dirty sata port which can hardly be attributed to my machine. Power failures will not show any adverse effects on your drives as they are treated as a single drive by windows. Windows has no clue that there is more than one drive in your machine in a raid array.

It shouldn't at all. I have 2 partitions on my harddrives 1 for games and personal data and one for system. Well I was in windows and it crashed hard. Turns out that when I was in windows a sata port crapped out due to being dirty. Well I lost my whole comp until I reinstalled windows in my system partition and the other partition was left unharmed. There was no data corruption at all. Just make sure any personal or critical data or proggys are not on the same partition as your OS and your good to go.

It's not super sensitive to sudden shutdowns, if that's what you're asking. I've had the power killed numerous times and haven't lost any data or had any corruption.
