    Reliability of WD RE4 vs WD CB 6Gbps

    The WD Caviar Black 6Gb/s has been out for over a year now, and I'm curious to hear some feedback as to what folks have noticed between the WD RE4 Enterprise Storage drives vs the WD Caviar Black 6Gb/s drives, especially being that they seem similar as far as overall spec.

    We have been using the RE4 1TB's and have not had any issues, but then again we have not been using them long enough to really say they are flawless.

    Speed? Fail rate? Any feedback would be appreciated.

    I've used the Black 6Gb/s drives a lot in the last few months have not had any issues with them yet. I've also not had issues with the RE4's.

    Maybe someone else here has had issues with them and could give more info.

    A 0.1% failure rate? I can't believe that. Even the best hard drives have failures. With such a low rate - one might consider not bothering with RAID - but yet none of us do because disks fail quite often.

    I've only had three drives die on us out of a good 1000
    Still never know when it could do so raid is always nice.

    Perhaps his failure rate is not the norm...but do believe that the RE4's are rock solid. We haven't had any issues with ours although we are not in the 10's of thousands so our sample size isn't as large. Take a look around WHT and you will see for the most part the success people are having with the RE4's.

    Oh, I totally agree that the RE4's are pretty amazing drives overall with speed, reliability, power use, etc. For my 3.5" drives, I'm using WD RE's as well. Previously, I had a lot of bad luck with various Seagate 3.5" drives from numerous batches and differnt purchase windows and switched to WD. Never looked back. I'm just shocked to hear that anyone - even WD - could get failure rates so low. If so - then color me impressed for sure!

    I've not had nearly as good luck with the RE4 drives as some of you folks here have. Of about the 80 that we've bought in the last year we've already had 10 die. Most of the ones that have died have been the 2TB variant.

    I think the WD RE and Blacks are the same, the only thing that changes is the firmware. RE have TLER enabled...
