Intel IOMeter File-Server & Web-Server Patterns
These patterns emulate the typical load on the disk subsystem of a file- or web-server. The File-server pattern comes first.
The drives split up into three groups while working in RAID0 arrays. The first group includes the WD4000KS all alone. This HDD enjoys a colossal advantage over its opponents at high loads.
The Hitachi and the two other models from WD are contending in the second group. It’s hard to tell the winner among them as the Hitachi is faster at low loads and the WD drives at high loads.
The third group includes the HDDs from Seagate and Maxtor. No comments about these two.
The WD drives seem to work better than the Hitachi in RAID5. The three HDDs from WD are the leaders here.
The WD4000KS doesn’t feel at ease in RAID10 at low loads. But as the load grows higher, this model overtakes the other HDDs from Western Digital and claims leadership for itself.
There are no write requests in the Web-server pattern, so I guess the WD4000KS is going to be in its element there.
That’s right. The Hitachi is fast at low loads, but the WD4000KS proves its superiority eventually.
We’ve got the same picture with the other array types. The WD4000KS wins this round.
