Sudden drop in Macrium Reflect backup speeds under USB boot rescue environment
This one is likely specific to my machine, but hey. Problem: Macrium Reflect backup times in the WinPE boot rescue environment (i.e. booted from a Macrium USB stick) suddenly change from acceptable (~500-700 M/s, 1-6 hours) to ridiculously slow (< 40 M/s, 100+ hours). Macrium starts well, but "hesitate" about 3-6 seconds after starting a backup (no updates on screen), after which read speed is updated to a very slow number. Additional hesitations may occur as Macrium struggles to read the source disk. Speeds under Windows proper are fine, and this will occur when writing to multiple backup targets (i.e. to NAS, to another internal HDD/SDD, to an external USB HDD, etc.) There are no indications of problems with either the source disk or the target disk. Possible solution: Try swapping your source drive to a different SATA port. This is a nasty one, as no one expects a SATA port to misbehave. Because they never do. In my case, I thought...
