Have you ever wondered if that killer video card you’ve been eyeing for months
will be compatible in Linux? Or maybe you saw a great deal on a new hard drive
on eBay, but aren’t sure if you should spend the money. The Linux Hardware
Database is a great place to find out if that new hardware item will function
well in your Linux system.

The Linux Hardware Database covers every type of hardware from hard drives to
memory to miscellaneous cards. The site also features a ratings system that
ranks compatibility and functionality in Linux from 0 to 5. Devices are even
searchable on the site by product name. This is the definitive site for up to
date information on hardware compatibility with Linux.
