It has already been a year since I upgraded to an Intel i7 920 with 12GB of memory and a 64 bit operating system.

Images plus now has no practical limitation on image size. In fact I can open forty 25MB fits files and manipulate them all in memory.

Using DSS I can stack 40 X 200MB images in a reasonable time about thirty minutes.

Storage of data has always been a problem. Any sort of backup is slow and impractical. I tried network storage backup and it just slowed down disk access.

So I lashed out and bought a full tower case and a 1250W power supply.

The MB has ten sata ports so theoretically I can have ten hard drives

Below is an image showing the current hard drives. The operating system HD is already a raid 1. I will make the two newly obtained 2TB HD's a raid 1 as a safe backup and storage.

The two 279MB HD's will be a raid 0 to almost double the R/W speed as a scratch disk for processing. This is the major bottleneck as usual.

As the large disks fill up I will replace the 'smaller' drives that seemed so large not long ago with 2TB ones and again set them up as raid1.

This is not the only answer to safe storage and easy access to data. But when a 2TB drive only costs about $170 I can see no better way to go.
