Hi, my database requires 1TB of disk space, but I want to avoid RAID (e.g. 8x 300GB SAS drives in RAID 10), and use rather a 1TB SATA disk. To avoid the "slowness" of SATA showing in queries, I want to cache lots of the database, but I don't want to buy more than 16GB RAM. (Budget limits). So I'm considering configuring a large cache, requiring larger than 16GB, and allowing it to "spill over" into swap space on a single 300GB SAS drive. Is this a good idea?
