Comment Had one die twice (Score 2) 510
Had an aftermarket SSD for a macbook air fail twice in 2 years (threw it out and placed an original hdd after that). Both times the system decided not to boot and could not find the SSD.
In both cases I have suspected that the Indilinx controller gave way. This seems mirrored in quite a few cases with the experience of others who had drives with these chips in them.
In an ideal scenario the controller should be able to handle the eventual wearout of the disk by finding other memory cells to write to. Any cells that have been used up should still be readable as well since the floating gates basically have been filled up with electrons and will not allow further erasing.
I guess the main issue right now is the fact that SSDs cant notify the user once things get a bit too worn out. Eventually the controller wont be able to keep up with the useless cells and then might simply no longer respond. Things will only get worse when the cycles go down due to smaller manufacturing processes so that useless controllers in cheap SSDs are more likely to fail
