Need RAID-0 expert with Apple experience.
Think I am exceeding my inherent CPU or bus speeds.
Therefore, do not think the magic bullet of beefing up my RAID-0 will help.
(hope I am wrong about that)
Macbook Pro one year old:
OS 10.10.3 (Yosemite)
CPU 2.6 GHz Intel Core i7
Memory 16 GB 1600 MHz DDR3
L2 Cache 256 KB
L3 Cache 6 MB
Memory 1 TB SSD
Am using Carbon Copy Cloner utility for a 100% clone backup.
Works great, takes 3-minutes to backup my main internal SSD (10 GB )
My input to CCC is a RAID-0 of two USB3 spinning drives.
My output of CCC goes to a RAID-0 of two Thunderbolt-connected SSDs.
My friend has a similar Mac with 365-GB of stuff to backup using CCC.
Takes him 73 minutes to backup - - - intolerable.
Just for kicks, trying to help him shorten that backup time.
If I beef up both RAIDs to four drives instead of the present two drives, is that likely to shorten his backup time to 40-minutes?
Possibly I have hit a stone wall with the computer itself, so improving the RAIDs might not help?
