The only serious issue I've had in 7 years of running the OS on an SSD (drive C:) and my primary data storage on hard drive (OS user libraries on D:) was a Dropbox update that ignored my previous configuration of the Dropbox folder being on drive D: and tried to rebuild it on C: after the update. The Dropbox folder is my business' and is huge and overflowed drive C:... Even worse there was no obvious way to repoint Dropbox to the original folder on D: after the update. One of the very few times I had to call customer support to get it straightened out.
Likewise for me - All my fixed machines are running SSD system drives, and likewise I redirect SOME of the front end folders to the storage drive(s)... Generally just pics and vids, moved off the front to D:\Media\... The rest are picked up in backup or syncing, and I mainly just want the fat folders off the system drive...
But this laptop dvd to hdd adapter is a real game changer for me. My Alienware large form factor i7 laptop had two drive bays, and it spoiled me rotten, but that is the only one I have ever owned with that capability.
I ordered one to try it out, but if it works as advertised, I will order 10 more... Nobody needs a DVD onboard anymore, and every laptop from a decent quad-core on up becomes really viable if I can hang a system SSD and a storage drive in them... And I easily have 10 on the shelf...
This is a major hump in my personal get-along, and generally too... Big SSD's are too spendy to shove in an old box, and little SSDs just don't have enough room. But a small SSD and a companion large storage drive is just the ticket... And something formerly unobtainable in a laptop.
What bugs me now is that I didn't think to look for this adapter years ago.
