1) 3-drive RAID array -- Lightroom Equipment
I've completed this purchase -- Total Price $210
At our local Fry's Electronics I was able to purchase three Maxtor 320GB 7200 RPM drives at $70 each, regularly $110.
This weekend I will be setting up my http://en.wikipedia.org/wiki/RAID_5#RAID_5
to ensure protection of my data, specifically my digital photos.
One drawback of a RAID setup is a slowdown in Read/Write times to the disk array. This isn't bad for mass storage, but for files that I'm working on I would like to ensure a faster Read/Write time. Therefore, my data center will look as follows:
C: Boot Drive (small SATA drive, but 10,000 RPM) -- contains my applications and OS
D: Scratch Drive (IDE 7200 drive, non-RAID) -- contains my current working area, requiring regular backups to RAID
E: RAID Drive (3 320GB SATA drives, 7200 RPM) -- contains all my core data that require minimal Read/Write, such as images, mp3s and budgeting information. This provides about 600 GB of storage.
