Video: Shouting at disk drive causes high latency, low morale
Here's a tip for everyone who hasn't made the jump to solid state: try to be nice to your disk drive. Brendan Gregg from Sun's Fishworks team wanted to see the effects of vibrations on his disk array, so he proceeded to shout at it. On video. Yeah, we bet that's pretty embarrassing for the drive in question, and what results is a sharp spike the number of I/O operations that take over 5ms to complete. Moral of the story? Yelling at your computer isn't going to make it run any faster. How about next time we see how it reacts to Ozzy, Mozart and warm, gentle nuzzles? We've placed video of Gregg's sadistic hardware taunts after the break.[Via Slashdot]
Hitachi Maxell 1TB SVOD optical disc cart
Good morning, kids. Are you ready for the optical disc format of the day? It's Hitachi Maxell's 1TB stacked volumetric optical disc (SVOD) array, comprised of rather thin DVD-size discswith DVD-size capacities: 9.4GB total storage each on two 92µm thick data layers. Yeah, we know, we promised a terabyte; well, watch and learn. These polycarbonate discs may be too thin to be manufactured from typical plastics, but they can be stacked in an optical array 100 tall, and 6.5 x 13.3 x 16.1cm (2.5 x 5.2 x 6.3-inches) in size. Even though Hitachi Maxell wants to make the terabyte carts relatively cheap at ¥40,000 (about $340 US) and claims there are consumer applications, don't toss that HD DVD player just yet. It's pretty easy to realize why optical arrays are really of only limited utility for the end-user; if these should ever be popularized, we'd imagine it would serve first as data archival medium for businesses before you'd ever outfit your rig with, like, the high def optical disc system, dude.[Thanks, Andrew]
