I want to build a new server or at the very least get some new drives. I would like to have at least 1TB drives and use RAID 1. However, in the past with just 500GB drives I had some problems getting them to sync. I sent the problematic drive back to WD and they mentioned that it wasn't designed for RAID use and because of it's size it may have difficulty syncing.
I have looked at both the enterprise drives ($$$) and regular drives ($$). I only can really afford the regular drives right now, but I could wait.
My question: Will regular drives work ok? I mean it is Redundant Array of INEXPENSIVE Disks, right?
Distribution: CentOS, RHEL, Solaris 10, AIX, HP-UX

Rep:
Software raid works well with nearly all available disks. Syncronization requires longer on larger disks, but that's all. I use 2x2TB samsung spin point eco f4 disks in a software raid1 without any problem.
Standard consumer disks will be used in nearly any low budget NAS device, so i see no retriction from hardware site.
One of my machines has 4 x 1TB in RAID10, another 2 x 500GB in RAID0, and yet another 1x (well, 5/8ths) 500GB and 1x 320GB in RAID1. All mdadm and they never give any trouble - the RAID10 one has even suffered (and coped with) drive failure. With the larger drives they will take a while to sync due to the sheer volume of data.
