Our favorite File Copy Test is the last on our test program.
We create two logical volumes on the arrays, 32GB each, and format them in NTFS and then in FAT32. Next, we create a file-set on the first volume, then read it, copy it into a folder in the same volume (Copy Near), and finally into a folder in the second volume (Copy Far).
The first test brings a surprise already: when united into RAID0 or RAID10 arrays, the HDDs from Maxtor and Seagate are not very successful at creating small files. The Hitachi drives are surprisingly weak as a RAID5 array. The only drive I can find no fault with is the WD4000KS!
The HDDs have similar results but we should single out the WD4000KS again. This HDD performs superbly here.
Small files again, and the HDDs from Seagate, Maxtor and Hitachi again have problems.
The file-sets will be read now.
We’ve got some variation at last. It is the Hitachi drives that seem to be the best here while the WD4000KS has the worst speed. Well, it’s just impossible to be always the best…
