Review: Allan "Zardon" Campbell
My test system of choice is : Athlon Barton @ 245x10
- 2450mhz @ 1.9 core volt All testing was done
with a fresh format of each drive to ensure no fragmentation and to
eliminate any possible corruption of accurate benchmarking data.
SiSoftware Sandra (the System ANalyser, Diagnostic and Reporting Assistant) is an information & diagnostic utility. It provides most of the information (including undocumented) you need to know about your hardware, software and other devices whether hardware or software.
Western Digital JB SE 80 gig - Drive index 30506
The western digital 80 gig drive (above) puts in an excellent set of results obviously helped by the 8 meg cache
Western Digital Raptor 36.7 Gig - Drive index 38268
A sterling set of figures for the Raptor with a reported average access time of 5ms, very low and the reference figure quoted by Western digital, the 80 GIG IDE drive has a reported acces time of 7ms, a little better than reported figures.
We are seeing noticeable increases across the board, abeit with a surprisingly low figure for the raptor in the buffered write test. This is more than likely due to the way the drive is designed rather than a fault of any kind and as I will report later, real world tests certainly do not show the drive to be slower in any area of performance. Sequential write is substantial higher >10mb Fragmentation: It is important when testing drives to ensure that it is either defragmented or a fresh format, "why?" I hear you ask. Check out the differences in the image at the top of this page and the one below detailing the 80 gig drive before a format with a one month old OS install.
Heavily fragmented drive, a clear indication of how fragmentation kills performance.
