All done. Seemed to speed up and complete the clone in 3 hours after taking nearly an hour to do the first 30Mb.
Sata IIi is faster than Sata Ii. Can’t recall by how much. However the overall speed is only as fast as the slowest bit out of: Motherboard interface, HD interface, HD itself etc. 5200 rpm drives are quite slow.
You can get very cheap hybrid drives. £75 for a 1TB 5200 rpm drive with a 64 GB SSD built in. This is a good option. A 750 Gb SSD would cost £500. My 500 Gb SSD was £320. If you need more than 500 Gb I’d just buy a bigger HD or a hybrid drive.
