Next stop is HDD.
I was planning to buy 2 x Caviar Green HDDs and set them in RAID1. However, it looks like WD green drives fail like no one else and are not recommended in RAID array due to access times as RAID controller will drop the drive from array?
If you install and use a desktop edition hard drive connected to a RAID controller, the drive may not work correctly unless jointly qualified by an enterprise OEM. This is caused by the normal error recovery procedure that a desktop edition hard drive uses.
When an error is found on a desktop edition hard drive, the drive will enter into a deep recovery cycle to attempt to repair the error, recover the data from the problematic area, and then reallocate a dedicated area to replace the problematic area. This process can take up to 2 minutes depending on the severity of the issue. Most RAID controllers allow a very short amount of time for a hard drive to recover from an error. If a hard drive takes too long to complete this process, the drive will be dropped from the RAID array. Most RAID controllers allow from 7 to 15 seconds for error recovery before dropping a hard drive from an array. Western Digital does not recommend installing desktop edition hard drives in an enterprise environment (on a RAID controller).
Is this true? I have no idea why WD says that Greens are not compatible with RAID 1 yet their external HDDs use Greens. Is this WD specific or not?
1.5-3TB is what I am looking for with lowest plausible noise and faster access times.
Another option was EcoGreen F2 or Hitachi Deskstar 5K3000 but they too have bad access times.
<15db would be ideal.
EDIT: After some research, I believe my best option is Seagate Barracuda 3TB ST3000DM001? They claim to support RAID 1, are fairly quiet and offer superb performance.
Any speculation on what would the surface noise be like with the Design XL case? Is it realistic to expect <10db?Edited by Kauke - 2/2/12 at 3:21am
