This is the same as the previous test except that we are writing to the disk instead of reading from it.
And we get the same picture as in the previous test: the drives rank up according to their data density. Now, we switch to two threads again…
And there’re no great changes! Well, the Maxtors have pushed the WD drives a little down the diagram, and the two drives from Seagate with 8MB of cache memory have sunk to the bottom (meanwhile, the Hitachi drive with as much of cache shows a much higher speed). But the main thing is that the Seagate drives don’t suffer a catastrophic speed slump here.
The more threads there are, the better positions the Maxtors occupy. The ability to make good use of the cache buffer prevails over the “raw” speed of writing to the platter. By the way, the two Seagate drives with an 8MB cache buffer have improved and outperformed the ATA drive from Hitachi.
So, the threaded tests prove the necessity of having a large cache buffer as well as the ability to make good use of it. Combining both, the Maxtor drives put on a brilliant performance in this test. The awful results of the Seagate drives at processing multiple read threads makes them antiheros of this test.
