I am making a disk-to-disk clone using CloneZilla where both source SSD and target SSD are connected to the computer using SATA-3.
Both drives are from the same Vendor and have the exact same size and read/write speeds (Samsung, 250 GB, 400+ MB/s).
CloneZilla is showing me that that the transfer rate is 2 GB/minute, which translates to 33 MB/s.
Why is the transfer speed so slow?
I also tried cloning the drives via USB 3.0 which doubled the speed, but still, why is it so slow?
Shouldn't the transfer rate be close to 400 MB/s at least?
What is your Motherboard? – NetworkKingPin – 2016-06-16T04:36:25.837
It is a GA-X58-USB3 – vaid – 2016-06-16T04:59:04.580
One last question how are you running clonezilla exactly? this could affect your speeds depending on where you run it. – NetworkKingPin – 2016-06-16T05:07:41.777
To be exact: I am running it in a virtual machine. I have set up the SOURCE SSD to act as a physical drive inside VirtualBox. Like I said in my post: The exact same setup but with USB3.0 Source to SATA Target gives me twice the speed, but still 10th of the speed expected. – vaid – 2016-06-16T07:39:53.117
What kind of virtual machine? What solution are you using? Are they attached to a physical SATA-3 controller? – Seth – 2017-01-26T08:21:15.327
