Re: No-one will ever...
More to the point, the 2.5inch format is about the largest form factor you can make and still reliabily dissipate the heat (and that really only in 7mm thickness)
3.5 inch SSDs keep on being announced, but are endlessly plagued with heatsinking issues. The format worked for spinny things but it makes zero sense for solid state and trying to force the SSD square peg into that round hole isn't a good idea.
