The ATTO ExpressSAS R680 RAID Adapter

To effectively edit high-end HD projects you’ll need a RAID, which is just a bunch of hard drives working together to deal with the huge amounts of video data that are being manipulated. And if you’re editing DV at 25Mbits/sec, you’ll have no worries as 25Mb divided by 8 bits per byte equals only a bit over 3MB/sec, which any hard drive can handle. But there’s a problem when you work with larger formats, like the one recorded on Blackmagic Design’s HyperDeck Shuttle. The full, uncompressed 10-bit recording rate of 1264Mb/sec or 158MB/sec is more than any regular hard drive is going to be able to handle. An SSD can deal with the speeds, but who can afford to own terabytes of SSDs? What you are left with is SATA and SAS drive RAID arrays to process all of your data.
