It would be so nice to have the option to defrag multiple disks at the same time. I have (4) internal hard drives, and (2) external hard drives, totaling ~6TB of storage. It takes forever to defrag those drives individually.
Thanks!
You can already do this, just highlight more than one drive and click defrag
Turns out that it does them sequentially, I hadn't noticed because the way I tested it was with one fully defragged drive and one that wasn't so much, and the first one "finished" so quickly that I thought that they were being done at the same time.
My bad, ignore me
Defraggler does not work on complete physical drives, it works on the partitions which contain file systems.
Defraggler allows you to choose partitions to defrag. but I see no indication of which physical drive holds them.
I believe it would take much longer to simultaneously defrag partitions on one physical drive.
Simultaneously defragging one partition on each of multiple physical drives may be feasible - unless Windows API's get confused.
There's no much point of defragging multiple partitions on the same driver, but I agree there may be a benefit if multiple physical drives are defragged concurrently as the slow drives with high fragmentation may last for ever and the fast ones may be already completed in the meantime. Currently if it starts with the slow one the others will have to wait in queue
+1 to defrag different physical disks concurrently. For instance a SATA drive and an USB drive.

Need to be able to defrag multiple drives.
It is good to do partitions in sequence, but still need to be able to do simultaneous drives. Doing 5 drives in sequence is a lot slower than simultaneously.
You'd also want to take into account which disks are on the same disk controller. The max throughput of a controller is total, not per-disk.
wearenot, while this is true, the net effect would be faster throughput via more complete use of the bandwidth.
_______
Example: Drive A is sends data to be processed, & has to wait. This wait means there is wait, or "chunks" in the bandwidth. Incomplete saturation of the data channel.
Drives B & C are added to the lot. All 3 are being processed at once, & because the processor always tries to reserve time slot slices to be available for other applications, these take advantage of that fact, & more fully saturate the data channel(s).
_______
That is to say: While one drive would spend time waiting for the data to be processed, then send data, then receive data, the other drives could be sending & receiving on the wait cycles. This is far more efficient use of the data channel & has the net effect of being faster.
The data is flowing more like continuous with the other drives added to the bunch, & wait cycles are utilized for the other drives.
