Too right. Take those deduplicated blocks of your 8000 images, then place them on SATA storage... dirt cheap vast sata disks. When you go to pull those images - even a few hundred or thousand at a time - your SATA disks will populate the cache cards in your filer with most of the duplicate blocks - and your disks will never be your bottleneck when you're pulling them back down.
NAS tech has gotten real interesting with the introduction of good and large cache, deduplication, and giant cheap SATA disks.
