A:Answer An SSD is a blazing fast drive for your computer. Replacing your mechanical hard drive with a solid state drive will make your computer faster in almost every way - seriously you will be amazed at how an ssd can revitalize an old machine.
Specifically, the difference between an SSD and a mechanical hard drive is akin to the difference between a MP3 file and a old record player. A mechanical drive works like a vinyl record. When you need to access something on the drive, it spins up like a record and there is a tiny needle that reeds the data on the drive. That means if you need to read several files on different parts of the disk, the needle has to move back and forth on the disk to read those files. That takes time.
An SSD, on the other hand, stores files directly into flash memory. This means that there's no mechanical movement required to access files. Consequently, flash drives are much much faster than mechanical drives.
If you get one of these SSDs you won't be sorry! Your computer will boot up in a matter of seconds and copying/transferring files is a breeze!
