I can by a good quality fast 8 terabyte spinner for around $275. A 4 terabyte SSD will run you $1500.
Even though SSD reliability has improved a lot over the last 5 years, there is still a downside. SSD's pretty much always hard fail, meaning when they do fail there is almost never any chance of recovering data off the drive. Traditional spinners generally soft fail. They will usually start throwing errors or have difficultly spinning up, long before they are completely unreadable.
The big advantage to SSD though is definitely going to be speed, particularly if you move away from the SATA interface and get to the faster direct interface connections.

31.5 Gb/s (3.9 GB/s) |
By comparison a 7200 RMP SATA III standard hard drive will get read speeds in the 200MB/s range.
M.2 PCIe Gen3 x4 SSD drives will see data rates around
3500MB/s read and 2100MB/s write
That is a 10x performance factor
Wow. Cool info. Thanks.
So I guess my thinking about using SSD for audio being a bad idea outside of the cost issue is outdated, eh? I'm always late the party.
