Advantages and disadvantages of each backing storage devices
Solid State Drives - SSD
Faster startup because there is no spin-up required.
Much Faster than Hard Disks
Slow random write speeds – as erase blocks on SSDs generally are quite large, they're far slower than conventional disks for random writes.
The inability to recover old data is one of the biggest disadvantages of a SSD
Solid state drives are highly expensive and are sold with a hefty price tag unlike conventional HDDs. Thus, SSDs are predominantly available in smaller and affordable storage sizes. The storage capacity is usually under 160 GB.
