I have multiple hard drives that I need to test & Wipe. I have testing software (Drive DX) for my MacBook and I'm using Apple's built-in Disk Utility to wipe the drive to DOD 5220.22-M standard. I am using a hard drive docking station to connect to my MacBook.
My issue is time. It is taking an excruciatingly long amount of time to test and wipe. The full test is around 2 hours for a 1TB drive, which isn't awful but could be better. The wipe seems to go on for hours and hours without an end in sight. (It's a 7 pass wipe which I know takes some time but it shouldn't be that long!)
My current HDD Docking station is USB 2.0 (data transfer of just 480mb/s). I was about to invest in a docking station that will connect either to the USB 3.0 (5GB/s) or the Thunderbolt 2 (20GB/s) on my MacBook - but stopped myself as I ask this question.
Will the data transfer speed of the Docking Station / Cable even matter if the Hard Drive has a Read / Write speed of say 100Mb/s? Does that affect how quick I can test & Wipe the HDD? And Does data transfer speed affect the speed of which I can test / wipe anyway?
(I'm sorry for the essay, any help will be much appreciated!!)
