R-Explorer RAID recovery
Posted: Wed Feb 20, 2019 4:14 pm
I have a case where the destination drive is just a little too small for my initial desire to destripe to a single drive using R-Studio. So, although R-Studio destripe was able to achieve 235MB/second, we are now using R-Explorer to save the data out, file by file, to the HFS+ formatted destination drive.
I got a hint from @Iurii to enable cache on each of the drive clones, then build the RAID using the cached versions of the drives.
So, in my case, I'm saving out the data at an average speed of about 80MB/second, with times when it breaks 200MB/second
The caching may not be making a huge difference here, but in a case where we have a RAID with a block size of 1 sector (512 bytes), the cache will make a data transfer that is unbearable to become a lot more workable.
