Now let’s consider the results obtained for RAID 1 array:
The best at creating files appeared VIA VT6410 and ITE IT8212F. The first one turned out more efficient for large files, while the second one worked best of all with smaller files. The third position can be given to Promise TX2000, and the very last one – to Promise 133Lite.
File reading appeared equally fast on all four controllers, which doesn’t allow us naming any of them the winner. The performance gap between all four controllers is minimal in all five patterns.
File copying within a single partition is carried out faster with VIA VT6410 and ITE IT8212F controllers. Moreover, the latter is more efficient here. The performance of our array appears considerably lower when we use Promise controllers. Note that Promise 133Lite looks a little bit more attractive than its counterpart.
File copying from one partition to another doesn’t reveal any significant changes. Like in the previous case, the array performs much faster when it works with VIA VT6410 or ITE IT8212F controllers. The latter is again a bit faster, like in the previous case. And again 133Lite controller from Promise looks more attractive to us.
