Until now, I've been using two USB hard drives for backups (one for my daily backups, the other which is usually offline for ransomware airgap is used weekly). At around 20MB/s write speeds I was disappointed and decided that the price of 4TB USB SSD's is now down to a reasonable price and I went for it. I got two.
I got a Samsung 4TB (quoted speeds of around 1000MB/s) and a Crucial X6 4TB (quoted speeds of around 800MB/s).
Backing up from my daily backup drive to the Samsung SSD I was only achieving writing speeds of around 40MB/s and it took over 24 hours to transfer nearly 4TB. I figured it was the source drive that was slowing things down. Then it came time to populate the second SSD. I figured copying it from the Samsung SSD to the Crucial SSD would be by far the quickest way (rather than repeat copying from the original daily backup 'hard drive'. Not at all. I'm watching it copying now and it varies from around 6MB/s up to around 27MB/s. The estimate explorer copy is currently showing is "More than 1 day". I was expecting at least 400MB/s and possibly close to the Crucial's 800MB/s. No such luck. Oh, as I'm writing this bit it's surged to <sarcasm>a massive 38MB/s </sarcasm>.
This is a fast laptop. It's running at a trivial CPU load, has its drive C as an SSD also. There's nothing I can think of that's slowing it all down. Both drives are plugged into 'blue' USB ports (therefore USB 3+) and directly to the machine's ports, not via a USB hub. They were first plugged in via a hub which is why I tried plugging them in directly just now, hoping the hub was the issue, but no. I've also tried three different ways of doing this copy, first time was with GoodSync, second time copy/paste using OneCommander, and thirdly using native Windows Explorer.
Any ideas?
