Some years back when I began working in the SSD VPS business I didn’t recognize what an “area name” is, yet what a SSD is. It was two years prior when I first found out about SSD and I’m almost certain there are numerous as myself pondering what is a SSD, what is the distinction between a SSD hosting arrangement and a HDD arrange and which one is best for their site.
Well that's an obvious one, SSD (solid state drive) is way faster than conventional rotating disks HDD.
Read, seek times are faster.
For hosting purposes SSD is a great solution. That way you can actually not keep everything in the RAM and have quite high read/write speeds to disk.
Problem with SSD is that they cost more, so you will have less disk space for same money.
