Solid-state drive

Published:

awesome performance using solid-state drive for server or PC
and if the MTBF is 1,200,000 hours … it would be expected to have one failure every 150 days

Unfortunately, most manufacturers don’t share this information freely. But when it comes down to it, most consumers should find any MTBF over 1 million hours to be acceptable. This generally indicates about 3 failures a year across 1000 drives that are used 8 hours a day. In other words, you’d have a 0.3% chance of having a write operation failure within the drive’s warranty.

A better way to get an idea of how long an SSD will actually last for you would be to consider the Total Bytes Written spec, or TBW. Although this is another ‘overall expectation’ figure and doesn’t directly tell you the lifespan of a drive, it will give you an idea of how one drive compares to another. Unfortunately, not all manufacturers give out this spec either.
