But then mechancal HDD's are also subject to failure. Sometimes catastrophic failure wth little or no warning. So really SSD's are still in thier collective infancy as storage tech goes. They do have merit in their w/r speeds but are limited in that finite capacity as well. While mechanical drives are not as fast, they can out last their ssd counterparts. I have an MFM drive that still works that is very old (about 1988). I use mostly as a paper weight.
On a side note: My Origin laptop uses a Momentus XT hybrid 500 GB hdd drive but I use a usb-3 sata 2 back up drive for the bulk of my data (just in case).
