This pattern features a large share of write requests which may affect the performance of the drives.
First, we ran the test on the full capacity of the disk.
Like in the previous case, we marked the best results in blue and the worst results in red. Then we calculate the performance ratings for the drives:
We seem to have got some competition now.
Seagate’s drives take up almost all of the top of the diagram. There’s Caviar, a drive from Western Digital, in the school of Barracudas. Well, it’s only the Seagate ST3500630AS that really stands out among the top eight drives. The remaining seven have similar results.
Next we reduce the address space to 32GB and repeat the test once again:
The reduction of the address space affected best the performance of the Hitachi HDS725050KLAT80 which is now considerably better than its opponents. Maxtor’s drives are all noticeably slower than their competitors in this pattern. The other drives have similar results.
