Since SSDs are flash memory, each sector is instant accessible at <1ms! The MTRON drives featured on this site boast an access time of .1ms. That is 84X faster than a 74GB 10,000 RPM Raptor Hard Disk. The MTRONs also read at a sustained 100MB/s! Since there are no moving parts, SSDs are super-rugged. You can drop your laptop, or operate your tablet in the field with no fear of damaging your data. Pilots can install and SSD in an aviation laptop with no altitude limitations (hard disks will fail above 10,000 feet). SSDs operate in absolute silence, so they are great for home theater applications.
SSDs outlast hard disks by a factor of at least 3 to 1. 1,000,000 to 5,000,000 hour MTBF (time between failures) rating mean your computer will become obsolete before the SSD fails. Forget what you think you know about write cycles too. MTRON SSDs will last >140 YEARS if you write 50GB per day to them.
Standard temperature SSDs operate in a wider temperature environment than hard disks can (0 to 70C) while industrial (wide temp) models operate from -40C to 85C (-40F to 185F). SSDs run cooler and consume a FRACTION of the power of a hard disk, making SSDs ideal for everyone, from portable use, to energy-conscious desktop use, to massive server farms.
