Image Processing Computer Upgrade.

[avandonk]

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.

As I read this, I heard an echo of a much younger mini-me in a land far far away in a time long forgotten saying that 640KB of RAM was heaps and I can't imagine what possible use I will have for a 10MB hard disk or a modem faster than 2400 baud. Ah me oh my!

I paid $26,000 for a megabyte of minicomputer RAM once back in the late 70's

That sounds like a nice setup, Bert. I need to upgrade my desktop system soon and I have been thinking about something similar.

Cheers,
Rick.

Peter in 1969/70 we upgraded the memory in our DEC PDP8 from 2k to 32k! We were stoked. Machine code was the go, as higher level languages just used too much memory. What we have now is absolute LUXURY!

This is a reply to you as well Rick. I don't know how to do multiple quotes.

Next to the Quote button is a button with "+ on it. Click that one on all the ones you want then the Quote button.

Ah, yes. The good old days when hardware was expensive and programmers were cheap. But you try and tell the young people today that... and they won't believe ya'

Yep I remember that, I learned some basic programming on a PDP11 as part of my training.

The first computer (a Z80 based machine) I had was just 16K.
I upgraded it by soldering two extra layers of chips on top (from memory all legs but the RAS and CAS) to make a massive 48K.

I have an I7 (860) as well, only 8Gb of RAM but it sure flies, I really should put the OS on a couple of RAID drives for some extra zip.
