CD-ROM spinup, file access lag

Newly installed 40X CD-ROM has to "spinup" each time before it will access a file or open a folder.If I'm exploring and I click on a folder (to open it) there is a delay as the device spins up to speed.It will stay at speed for a few moments then drop down again. File x-fer rate is OK.(50meg file in 23 sec.)I expect that this drive is supposed to access files without having to spinup to Max. speed.
My old 4X drive accessed files much faster.
setup: IDE secondary slave
CD-ROM: EPO CR-840S (sold under Newcom brand)

what is the question?

Generally speaking, CD-ROMs and hard drives have to fully "spin-up" to access to data so overall transfer rates are fast but waiting for it to get "up to speed" can negate this advantage somewhat.

Expanding on Somebody_else's comment to which I am in full agreement with.  I used to have a Panasonc 12x CD-ROM which absolutely flew.  Everything ran really fast on it.  It died, so I replaced it with a new 34x CD-ROM.  The spin-up time was significantly longer.  What this meant was on short reads (or playing games) where the drive would stop and start constanly, access speeds where decreased drastically.  However, over sustained transfers, the new drive shat on the 12x.

It is an unfortunate problem with new CD-ROM drives that they do have to speed up to full speed before reading - which can mean quite a few seconds!  I put an 8x drive back in my system for when I play games so I dont have to wait for the damn thing to load the next video/scene etc.
