  • Dedicated cache drive

    Ok, so I bought a really fast 2nd harddrive (wd2000jb), now I need to decide whether to make it my PS and WinXP cache drive, or if I should make it my primary and use my old one (slower) as the cache drive.

    Anyone have any opinions on this?

    From what I have read Photoshop does better if the cache drive is seperate from the main drive.

    I've never tested this, I keep both on the same drive and don't seem to have any issues.

      from what ive read , i think the faster drive should be your chache as this is the one that would be the one that is used the most after you load a program into memory.

        Wouldn't buss speed be far more important than access speed for this?

        I'm thinking about putting one of the old 40 or 60 gb in for purely scratch disking. PS CS indicates that some 16 bit .psd images are near a gig each so with 30-50 history states that should be enough

        Sorry about jumping into an old post but I just found it and this is an issue that I've spent at least a bit of time think over.

          I have noticed a speedup since I moved my VM and scratch to the second drive, but I don't know how much speed is because of the scratch and how much is because I moved the pagefile. But I do feel more confident now (like the risk has been spread out).

            Doug you mention your pagefile. I know the term but don't really know what (which) file(s) you are refering to. As yesterday is my first with XP, I'd like to learn about this and why it is important to back-up. Can you help?

            I put into my new box a 160gb [already had it] for programs, (2) 250 gb drives for data, and a 60gb that was in an old abandoned box for a scratch/cache drive. Then told XP to store data on the 1st 250 and wrote a batch file to copy the differences from the data on the first to the 2nd 250.

            If I figure out the pagefile I'll write another to copy it somewhere else too. In another post I mentioned a double density DVD Burner but haven't used it. The discs are still $10 at this point.

              By pagefile I simply meant the temporary file Windows uses for virtual memory. You can control it via the System control panel.

                I bought a 40gig hard drive to replace my dead 20gig one. I didn't have the old one partitioned but was wondering if I should partition this one. If so what size partitions should I use? I'm running win98.

                2nd Hard Drive
                by Sharon
                I am looking into getting a 2nd hard drive for my computer. I heard that it was best to put Windows Virtual memory and PS’s Scratch Disk on the 2nd hard drive. How do you have your 2nd hard drive set up?

                using an empty external FW800 drive only for Photoshop as scratchdisc?
                by pure
                does it make sense to buy an external FW800 (or FW400) drive only for Photoshop as scratchdisc, which is always empty?

                i work on a laptop (powerbook 15" 1,67) with an external TFT screen, and i found out that PS CS2 uses the external drives i have to swap images.

                Well it has been a year and it looks like I am about to lose my hard drive for the second time. It does take an extremely long time for things to load so I guess that is my clue.

                I ran the free PC Pitstop test and it flagged my C drive's extremely slow performance. It is a Maxtor...

                External hard drive for PS/CS
                by martyphoto
                I want to dedicate an external hard drive for use with PS/CS since my internal hard drive is becoming filled. Can I transfer the program and files over to an external hard drive or do I have to load the program into the external hard drive and then transfer the files. What about the plug insssssss.
