SanDisk today doubled the storage of its minute SanDisk Cruzer Micro USB stick to 8GB.

The 8GB SanDisk Cruzer Micro can now hold 1,600 high-resolution photos, 2,000 digital tracks or five hours of high-quality video in its 2 x 0.5-inch body.

The USB stick still has the slide-away thumb cap that protects its USB port. For Windows users, there's also U3 support that turns the SanDisk Cruzer Micro into a portable program launcher, with bundled copies of SanDisk's CruzerSync backup tool, a password manager and Skype preloaded when you buy the unit.

The new SanDisk Cruzer Micro works with both PCs and Macs and goes on sale in mid-September for $130 (£64). Existing models, ranging from 512MB to 4GB in size will remain in the product line-up.
