I see that there are 2 options:
1) Flex Pro v3 with 150 GB 15K SAS
2) 60 GB SolidFire SSD
(I use another server for backups, the disk space it's not a problem for me)
I have read that SSD is faster, but SAS is more affidable.
What is the best solution in your opinion for a busy forum? @digitalpoint @MattW @Slavik @oman
