But my main system, starting in 2012, has transitioned from a single 120GB SSD + a couple of HDD, to all SSD.
5 different drives, 500(boot drive)+250+250+960+120...totaling ~2TB SSD space. Including the original 120GB drive, which is now just cache space for the video and photo editing tools.
And the price tag is also nice, but everything is relative
If you throw away your HDD, your performance is likely going to degrade in a few things, since external drives can be slow, USB ones in particular. Looking for a new external one, I didn't even see much reviews covering the performance and I think we're now waiting for a modern generation of drives to take advantage of the new USB interfaces.
Anyway, what are you looking to improve?
