I’m running AJA System Test and I’ll watch the progress bar fly during each test while I’ll have a transfer in the 70’s MB/S and then about 2/3rds of the way across, it will hesitate for a sec and the transfer rate will drop to 20 MB/s or lower. I’m regularly getting single digit read speeds as well.
Is there any way to keep the transfer rates in the 70’s or 60’s?
I’ve got a drobopro with 8 2 TB hard drives. 4 are 5400 WD green drives and 4 are 5900 seagate drives. I’m running DD v2 as that gives the best performance. I’ve tried DD 1.7.3 and 1.8.4 as well. I’ve done the proper uninstall, reboot, install, and reboot procedure.
