Guest Jon Dobson Posted October 9, 2008 Posted October 9, 2008 I have 3 nearly identical Dell P4 pc's running nearly identical XP operating systems and software, yet one pc runs much more slowly than the others. For example, a program I recently wanted to install on all three units installed somewhat slowly but completely on the 2 faster units, but clogged the slower unit so much and took so long that I finally abandoned installation. My question is why does this one pc runs more slowly than the others? RAM is idential on each unit. The only thing different about the pc's are the hard drives- the two faster units have 160 GB drives about 60- 70% data filled and the slower one has a 20 GB drive about 80% full. I checked different drive specs today and did find differences in onboard drive memory and a few other factors. Can a different hard drive really make that much difference in speed even though everything else is identical? Thanks, Jon

I haven't seen a new 20 gig drive for sale for a few years now. Yes, many older drives are considerably slower than newer drives, because of factors like slower transfer rates, slower rotation speeds, and smaller caches. Also, comparing the free space percentage can be misleading. The 20 gig drive has around 4 gig free, the 160s have around 50 gig free. That matters to Windows and installation programs, which often require double the space of the final installation during the installation. If you're finding that performance is degrading on the 20 gig drive, that can be a sign that it's near its end of life. In fact it's likely that it's well beyond it, if you look at the MTBF values (mean time before failure). If this is the case, replace it. New drives are cheap. Where I am, 160 gig drives are around $50 this week (they drop regularly). I'd suggest that getting one and just cloning the 20 gig to it is cheaper than the value of the time you'll spend trying to recover from a failed drive. And yes, you'll probably find it faster.
