Originally posted by Rico SSD is far superior to disk drives. If I could afford it I would switch entirely to archiving with SSD.
Respectfully, I agree with stevebrot. SSD is faster, silent, but not as reliable for repeated access. It's also much more expensive than disks. And the speed advantage is significantly decreased when you network the NAS, even with gigabit ethernet. WD's Red (and Gold) drives are specifically designed for frequent read/write access, and are more durable than most drives, SSD or disk. I'm sure other brands have comparable drives, I'm only familiar with WD's.
