to multiple series of tests, the average write endurance of today's
flash SSD is of about 1 to 5 millions write cycles. And, the bigger the
storage capacity of a drive, the better it gets endurance-wise.
Let's do a little math. Let's take, say, a 64Gb drive.
2
million (average write endurance) x 64G (capacity) divided by 80M bytes
/ sec (That's the fastest for a flash SSD available today and assumes
that the data is being written in big DMA blocks.) gives the endurance
limited life in seconds.
That's a meaningless number - which needs to be divided by seconds in an hour, hours in a day etc etc to give...
The end result is 51 years.
So,
yeah... I don't think I'll still be using my 64Gb flash SSD 50 years
from now. So, if people are afraid, they can refrain from using these
drives, but I wouldn't recommend it, considering the boost in
performance they have to offer. |
