I recently bought a new SSD to replace an older one that's been in use for almost 10 years and that I strongly suspected was failing due to an error I got during the boot process. It turns out that the problem isn't one of hardware at all (evidenced by my restoring a Windows image of the original SSD to the new one and the problem still persisting), and probably more likely relates to Windows user profiles.
I've decided to use the new SSD as a boot drive anyway just in case the old one is on its way out, which I'm planning to use as a data drive until it dies. Assuming I've got the extra cables in place for this extra unintended drive, I only have one problem left - where to put it.
My case is a mini tower with no more drive bays and very little space. Can I simply place the old SSD in the drive bay that it was formerly in, but on top of the new SSD? I still have the 2.5mm spacer that came with the new SSD - would placing this between the two drives be enough, or would having the two in such close proximity cause heat issues?
How about sticking it with adhesive to the top of the case (the only remaining area of the case that is free)? I know the orientation of an SSD won't affect it in any way, but would the adhesive itself on a drive that generally reaches temps of up to 55C be a problem?
