I'm trying to finalize my plans for a T42P with flexview
. My computer background is a bit out of date (expert in the IBM 7094 and system 360 era).
Ahhhh....The Big Blue Golden days! Those were *real* computers!
1. will the T42 DVD writer perform the same function as a CD-RW? I'm thinking about the task of writing disks for backup and restore purposes, and for transferring data to other machines lacking DVD drives.
Yup...it will do everything a CD-RW does, except that it will also read and burn DVDs.
2. does the DVD writer record DVD+ or DVD- or both formats?
According to the specs on the IBM website: http://www-132.ibm.com/webapp/wcs/stores/servlet/ProductDisplay?lang=en_US&catalogId=-840&langId=-1&prmenbr=1&cntrfnbr=1&partNumber=73P3294&storeId=1&cntry=840
it will read and write DVD-R, DVD-RW, and DVD-RAM. It will only read DVD+R and DVD+RW. There are other threads on this board where people have identified the exact model number, I think, and performance.
3. is the 60 gig 7600 RPM disk much more noisy or does it vibrate much more than the 80 gig 5400RPM drive?
There has been much debate about this on this board and elsewhere. There is a recent thread on this discussion as well, "Difference between 7200rpm and 5400rpm." My impression of the consensus is that a properly functioning 7200rpm drive is sometimes ever so slightly noiser and hotter than the 5400rpm, but hardly noticable. There have been more defective and overly noisy 7200rpm drives, however, as well as problems in the past requiring critical firmware updates. Some people have also complained of audible clicking when the drive parks its heads (which between power saving and "air bagging", the drive does a *lot*).
The 7200rpm drive is, however, up to 20% faster under certain benchmarks (the ones meant to simulate realistic use), than the 80 GB 5400rpm. Basically, the latency in moving to a new position on the disk is less. The sustainable read/write rates are, however, nearly identical. Some people claim they can tell a difference in performance, others cannot.
