If the manufacturer actually had confidence in it's product, not much.
If the manufacturer knows the products are lemons, alot.
It'd definitely be a price polariser .......
Those cheap as chips SSD's might not look like such a bargain when you factor in the real TCO.
The way I see it is that most lower capacity SSD's eliminate 1/2 of the flash chips, which then for the average user, doubles the writes to those chips, ie 1/2 the operational life, or twice the likelihood of failure.
