There’s a sale going on at BestBuy at the moment on WD easystore 8TB External USB 3.0 hard drives. A massive discount which drops the price from $299.99 to $159.99. “What’s the big deal, though?” I hear you ask. “They’re just external USB drives”. Well, yes, but those USB boxes contain Western Digital RED (NAS) SATA drives which normally also cost $299.
It’s easy to open up the cases and pull out the bare drives to use internally. And if getting 8TB storage drives at half price wasn’t enough, the drives contained within these enclosures have double the regular cache. 256MB vs 128MB. With four of these, in a USB3 RAID enclosure, you’ve got 24TB RAID 5 for under $800.
