Firewire to scream at 3.2Gb/s

By Justin Mann on December 17, 2007, 6:10 PM
Both Firewire and USB have made leaps and bounds in advancements over the years, and as speeds have boosted they have become ideal for plugging in additional storage to machines. IDE and SATA still completely trounce them in terms of actual performance, though. To compensate, USB 3.0 promises much greater speeds than the current generation and now so does Firewire.

The new iteration of Firewire, called S3200, will support speeds theoretically as high as 3.2Gb/s, four times faster than the current 800Mb/s maximum speed Firewire supports. That's a significant speed boost, one that would make the standard very attractive for snap-in storage solutions. USB 3.0, however, promises speeds even higher up to 4.7Gb/s. But as we've seen in the past, the actual maximum speeds of these buses are rarely achieved. It will be no surprise if the two end up becoming neck and neck, though it's exciting in any case.

Depending on how you measure it,100 Megabit (Mb) = 12.5 MegaBytes (MB)Note the capitalization of Byte.This 3.2 Gb of speed would effectively give you 400 MB of bandwidth for a hard drive. (I'm using hard drives, and they are frequently the bottle neck in performance.) Which, a Raptor as my model for a fast hard drive, can only push about 150 MB of bandwidth. So this is a significant improvement. Potentially, you could run a RAID over such an interface. This approaches Fiber Channel speeds at 4 Gb, but falls short of 8 and 10 Gb fiber channel. Hopefully, the boost in speed will lower the cost of Fiber Channel and other higher-end technologies as they now have a viable competitor.

The interface can handle 3.2Gb/s, but can hard drives deliver data at this speed?
