IBM has built "the world's quietest" range of mobile hard drives.

They use IBM's Drive Noise Suppression System (DNSS), which "replaces the traditional ball bearing design with the fluid dynamic bearing spindle motor technology and voice coil motor dampening enhancement".

Big Blue is also sprucing up its Travelstar line, capacity-wise. Top of the tree a 48GB HDD, touted as "the industry's highest capacity notebook drive".

Other IBM drives announced today are the 30GN (available in either 20GB and 30GB) and 15GN (in 6GB, 10GB and 15GB). These drives are designed storing fat files, such as music, video, music, digital photos and streaming media.

The Travelstar 48GH can store up to 48,000 high-resolution photos, 74 music CDs, 48,000 novels or 12 DVD films. This is around five times more data than the average notebook hard drive, according to IBM. And 50 per cent more than IBM's previous biggest drive could cope with - the Travelstar 32GH, which the vendor says is the current king drive in the area.

The 48GH monster weighs 155 grams and spins at 5,400 rpm, compared to the usual 4,200 rpm.

IBM aims to start shipping the new Travelstars in Q2. No pricing yet. ®
