A SSD is a Solid-state Drive so called because it uses Solid-state memory. A good example is the memory stick you use to transfer files from computer to computer. It is now replacing the traditional Hard Disc Drives that have been popular for nearly 30 years. The benefit of the SSD is that it has no moving parts meaning far quicker response times. When a traditional drives loads and saves it takes time for the drive to start spnning, the arms to move to the correct place and scan over the drive. They are also quieter, cooler, immune to magnets, electric discharge and radiation, more shock resistant and can be smaller in size.
The original disadvantages of the SSD are almost unimportant now as prices mean they are now as affordable as HDD were only 5 years ago and many of the problems with reliability and wear leveling have been addressed. Also the latest PCIe SSD are incredibly fast reading at over 800MB/s compared to traditional HDD at around 80MB/s. Don’t get too excited though as a 250GB PCIe SSD retail at around £4000 presently while a normal SSD will cost at current prices around £2 per GB

To see the power of SSD and how it can be used in a RAID setup for increible performance check out this YouTube vid. In theory this can be done with HDD but it’s not as easy.
