Need some opinions on hard drives now that the holiday discounts are coming up. Looking to up my storage space in my WHS and thinking that WD Blacks are the way to go? Currently I have a couple of WD 500g Greens and some other older lower end drives. I have 6 slots and two of those are the 500 gig drives. Looking at 4 drives in the 1.5 - 2 TB range. I used to be a fan of seagate until they had that 1.5 TB drive quality problems and now I am paranoid to try them again. (2 failed).
So for a system running 24/7 with weekly back ups, what would you suggest for drives? I have 4 TBs of space now, working my way up to 10.
Thoughts?
