Seagate Releases 3TB External Drive for $250
A few anonymous readers noted that Seagate has released a 3TB external drive. This makes it the largest 3.5-inch in its class, and it is available with USB 2, 3, or FireWire. That's more capacity than my entire four-drive RAID for just $250.
Storage is getting bigger and cheaper, you say? Unpossible, sir! I simply must purchase a dozen of these Slashvertised products forthwith, before this inconceivable trend reverses itself and leaves me flummoxed.
If you were blocking sigs, you wouldn't have to read this.
You'll be hard pressed to find a modern DB server under a significant read and write load that isn't using RAID 10 either directly or on a SAN to improve its IO throughput.
Only cheapskates and hobbyists use RAIDed HDDs for IO-intensive tasks. Decent SSDs blow away any RAID in terms of storage/watt or I/O by an order of magnitude.
