But this new one behaves the same so I suppose both the source and destination SSDs are behaving normally. It will automatically determine what has not been copied and only copy what still needs to be done.īy the way, a week or so ago I bought a 2022 Sandisk 2tb SSD (520mb/s model), but I exchanged it for a new one because it also took so long to do the copy so I thought something was wrong with it. you can run Syncback again and it will not try to recopy files that have already been copied. The advantage it has over a copy program is that if there are any errors along the way such as the drive disconnecting, power going off, computer hanging, etc.

It is a backup program that I have used for years. I use Syncback to do the copy with verify as I have done for the last 15 years. Over the years I have several times copied huge amounts of 1tb+ from an external portable HD to another external portable HD and it also usually takes 12-16 hours. After 13 hours it was almost finished with around 900gb copied. Not long ago I copied 1.1tb from an external HD NTFS to a Toshiba 1.5tb portable HD exFAT and it took about 15-16 hours.

It is still running smoothly with no errors during the copy. Does it normally take longer, much longer, to copy from an external SSD to another external SSD than from an external SSD to an external portable HD? And slower than from an external portable HD to an external SSD? And slower than from an external portable HD to another external portable HD?ġ3 hours ago I started a copy of 1.5tb from a 2019 Sandisk 2tb SSD (520mb/s model) NTFS to a 2022 Sandisk 2tb SSD (520mb/s model) exFAT.
