I've always used these drives in my servers as they are cheap and have good performance for their price.

I had 3 in raid 5 and they ran great and are still running now. I recently added 2 more drives, 7k1000.c to be exact (honestly not sure what they others are, but they are a few years older) maybe a month ago. BOTH are failing. I ordered 3 more, added two of them in so I can rebuild the raid on them and pull out the others... the two new ones are failing too!

I am currently trying the 3rd new one. This time I'm going to give it more burn in time before I rebuild the raid to it. so far so good...

Also one of the 3 newer ones only had one error, and it seems to have cleared but I still don't trust these drives anymore.

Here's some error output of a few of the drives:

Sure it's normal for drives to fail every now and then, but 4 in a row?!?!

Do not buy!

What about WD? They have been reliable to me for sure though I don't run them in a raid but for price I wouldn't buy anything else. Not the quietest drives but they survive some abuse for a few years.

Yeah I'm leaning towards WD or Samsung for my next drives.

Though I'm starting to wonder if I have another issue. The last drive that dropped out I put in another slot and it rebuilt the array with no new errors. I think I might have a more serious problem brewing on my server, which sucks as I don't really want to be trying to troubleshoot some weird I/O issues on a critical server.

Wouldn't even know how to trouble shoot an I/O issue, Way above me

But anyways ya I would have to agree that the odds of 5 drives failing that quick are low even if the company was running horrible quality control.

Only odd thing is you said you had 3 older drives in there also and they are fine right? Have you tried re-arranging the drives so the older ones are in the slots causing the failures?
I'm 99.9% sure you have backups so if your gonna lose another drive testing at least have the older ones take the hit / prove it's the new drives are bad

Never used hitachi though so I donno anything about there quality but like I said Ive got WD in my ps3 and PC right now. My external is also WD. Horrible noises started 2-3 months after buying the external but it was running in a very damp/dirty basement for most of it's life, It's at least 3 years old now has been moved alot and dropped a few times, never really cleaned of dirt but still runs very reliable. Really the noises coming out of it sometimes would make you cringe/panic/backup but its been doing it for years and has never lost a file.
