Imagine loading into Windows in around 20 seconds! A solid state hard allows you to achieve this.
The limit of course is the size, if this is an issue simply add a secondary drive. A standard Hard Disk works fine for storage
Solid state hard disk drives (SSD's) can make everything happen at about 5x faster , this has been the biggest advance in speed since, well, anything!
A computer with an Intel i3 processor and a SSD will far out perform an Intel i7 with a standard hard dive anyday.
SSD's are not only 5x faster but they use less power, make no noise, are extremely reliable and last significantly longer.
