The prices of older SATA SSD have really gone down now.
I have a RAID-1 of 2x 3TB HDDs as scratch storage for Steam games, mp3s, ripped movies etc
I am not even getting close to 1TB - lot's of games installed that I haven't played for a couple of years so I could go even lower, but 1TB is a convenient size where I won't have to worry about what to keep.
I am really tempted to get 2 x 'cheap' 500GB drives and RAID-0 them.
Currently 2 480/500/512GB drives are actually cheaper than a single 1TB one and you get better performance (and way better than HDDs)
I'm not too worried about losing data as I can re download most of the data and for the rest it is backed up in 3 other places.
Altogether it seem like a no-brainer to go ahead and do it.
Any downsides to this?
Obviously with m2 SSD already available this is not very future proof, but to get advantage of m2, I would need to change the motherboard and the CPU etc so not really feasible.
