Much slower to export to main drive than to external drive. Why?

[K***@adobeforums.com]

Thanks in advance for any help on this.

I recently built a new system for editing/gaming purposes. Specs are below.

Anyway, I installed a SATA-II Hitachi Deskstar 7K500 drive as my main drive, and I have several other external Maxtor drives connected by Firewire.

I have a 2-hour video project that I've finished editing. When I export it as a movie to a Firewire drive, it takes about 30 minutes to complete. When I export it to my Hitachi internal drive, it takes about 90 minutes!

I don't understand why - the Hitachi's specs are faster than the older Maxtor drives, and I've verified that it is indeed running at SATA-II speeds. I've defragged it, I've run CHKDSK on it, same problems. Doesn't make any sense to me at all, and makes me wonder if the drive is falling short in other areas with Premiere Pro.

Any suggestions from sharper minds than mine would be most appreciated!

My main system components are:

AMD 4800+ Dual Core processor
ASUS A8N-SLI Premium, Nforce 4 Chipset
OCZ DDR-400 RAM (2GB)

Eddie's Pro-Wiki's full of info regarding drive usage in PPro.

But quickly: It's best to have 2 internal drives; 3 is even better. If only two, OS on one, video, stills, renders, etc. on the other. If 3 drives, OS on 1st, video & stills on 2nd, renders, conforms, scratch stuff on 3rd. Export to 3rd (sometimes 2nd).

Good possibility for your current results: Expecting the OS to run itself, sample the input video, then write the output, all on the same disk, requires lots of I/O traffic along a narrow conduit. Getting any of that traffic to another spot will improve processing times.

But be warned: PPro does not OFFICIALLY support external drives. Many have gotten them to work, including myself(and you, it would seem), but it is not a sure/consistent thing.

Thanks for the feedback. This is what I meant when I said, "sharper minds than mine." :-)

It never hit me that the internal drive might actually be slower because of the OS, etc. that it's also dealing with. That makes perfect sense.

Suppose I should invest in another drive then, as my Maxtor externals are just about full (lots of archiving stuff going on).

And thanks for the reading suggestions! Will definitely check it out.

Sorry. And sorry for the same reference in Linda's thread. From now on, I will say "the Pro-Wiki that everyone smart uses and contributes to, that was envisioned, designed, created, and janitored by the most astute of individuals, the honorable Mr. Edward Lotter."
