SciDB Hardware Recommendations


I noticed that the last posts regarding hardware in this forum are 3-5 years old. Consequently, I was wondering if the Hardware Guidelines are still holding true.

Are you still generally recommending:
1 Instance = 2 CPU cores, 8GB or more RAM, one spinning disk for storage
In an application with a very small group of users.

Some older posts (160, 263) also suggest against HW Raid. Is this still up to date?
