Testing HDs before putting into raid.

I have a couple days until I can put the rest of my computer together so I am doing individual tests on the hards drives on a known good computer. I am doing individual tests on each drive to stress them into failing if they are faulty before I try to use them all together. I am using winthrax currently. Is there anything else that I could automate for several hours to do disk ios? Also I am testing 4 HDs at a time if possible. I have 8 total so doing the first 4 right now.
 
i had the same question on here a few weeks and didnt get a response i was completely happy with.
hd tune can do multiple Hds at the same time, just by opening more instances of the program. you can use the error check (surface scan) feature, which doesnt loop. or you can use the erase function which you can do a random fill and pass it as many times as you want. that was as close as i could get
. still not random access the drive to really stress it out, but ive eliminated troubling drive with that.
 
Well I did and initial HD tune to see that my first 4 drives were at least behaving well before doing anything. I have been running 4 instances of Bart's Stuff Test over night with an instance of WinThrax running in parallel also working all 4 drives. I am going to let the Bart's Stuff test finish up all 4 tests it runs (should be less than 8 hours I think). Then I will run the seatools long test on all 4 drives. So far one drive is showing 9 reallocated sectors! The others don't seem to be showing any smart errors. I will probably be returning the drive with reallocated sectors to the store as it seems to may be an indication of future problems.
 
The Random Write test is taking a lot longer than the sequential reads and write it seems like so It won't be finished until tomorrow morning i'm guessing. I'll kick off the seatools test then before work. So for a full battery of tests in this fashion it will probably take at least 36 hours for 4x 1.5TB seagate 7200.11s. Maybe 48 hours depending on how long the "short stroke" test takes. My sector reallocation count hasn't risen on the first batch of 4 yet still, 0-0-0-9.
 
I run a spinrite marathon on all my new drives, but that's not everyones taste.
 
Up to 13 reallocated on the one that was 9. Looks like bart's is defiantly weeding this one out...
 
I ran all 8 drives through 50+ hours of barts + winthrax. One came out with 19 reallocated and another with 73. Going to return both to Microcenter tomorrow. Is Seagate really running 25% failure rates on hard drives that have been run for 2 days?
