Nojima sent out my new 4TB Western Digital Green hard drives (model number WD40EZRX) on the same day that I ordered them and Sagawa (that is a courier service in Japan) delivered them to me on the next day. Sagawa is always like that. I'm glad that Amazon doesn't use Sagawa.
They came properly packaged to my relief. These were not bulk units so they came in their boxes. The first thing I noticed was how the boxes were ironically colored blue when the drives were from the Green series. In comparison, the 3TB drive came in a green box.
The drives came in anti-static covers and were additionally protected by bubble wraps. My old 3TB drive didn’t come in a bubble wrap.
I took them out and connected via the SATA to USB cable that I bought when I was troubleshooting the Asus UL20A years ago. First of all, I launched HDTune and checked if the drives didn’t have any errors. The Error Scan had to be rushed (i.e. I used the QuickScan) because I wanted to backup the data on the Toshiba drive as soon as possible. Both drives checked out fine.
Then I started copying the data. It took a loooong time. Since the converter cable was only a USB 2.0 one, the maximum speed I could hit was 40MBps. I had about 2.5TB to copy. That took me 18hrs straight. And that’s just one drive. The other drive took pretty much the same time.
I will post benchmarks of the new drives when I find time to install it directly through SATA.
I am considering getting a USB 3.0 cable but I do not feel that spending more money is worth it. It is this initial backup that was taking so long. After that it won’t be that bad I bet. I intend to keep the Toshiba drive in the PC for a bit longer. Then I will see if I can sell it off price.
