How Long Does My Passport For Mac Take To Backup?
Depends on how quick your Mac’s internal hard drive can transfer your files out to the My Passport for Mac drive. And how much data you have to back up on your Mac.
Looking at a couple of examples.
How Long With A Newer Mac With SSD’s In To A My Passport For Mac
Newer Macs and MacBook Pro’s and MacBook Air’s have SSD drives inside. An SSD is a solid state drive. A solid state drive is an electronic drive. They have no mechanical moving parts inside to slow them down. So they’re fast.
A typical read speed of a Mac’s internal SSD is 2259 MB/s. You’ll be connecting your WD My Passport for Mac over USB C on a newer Mac computer. Your USB cable won’t be the bottle neck here.
Your Mac will read your data from its own internal drive and write it to your Passport drive for Mac over USB.
The Western Digital My Passport for Mac’s typical write speed is 118 MB/s.
Look at the Mac’s internal SSD reading at 2259 MB/s. Versus your Passport for Mac’s write speed at 118 MB/s. You can clearly see that it’s your Passport for Mac’s external hard drive that’s the slower of the two.
Say you’ve 500GB of data on your Mac to backup.
To work out how long it’ll take to backup. The first thing is to convert GBytes to MBytes.
500GB x 1024 = 512000 Megabytes of files.
512000 divided by 118 give you the number of seconds on your My Passport for Mac.
This Equals 4338.98 seconds.
Divided by 60 gives you the minutes. 72 minutes or 1 hour 12 minutes to backup.

How Long With An Older Mac With HDD’s In To A My Passport For Mac
I tested my Old Mac. A MacBook Pro Mid 2010 with a full 250GB hard drive.
The read speed of the hard drive on the 2010 MacBook is 45 Mbytes/s.
Right away you can tell by the read speed of 45 Mbytes a second on the old Mac. Versus the Passport for Mac’s write speed at 118 Mbytes a second.
That it’s going to be the old Mac holding up the speed of the backup.
Convert GB to MB.
250GB x 1024 = 256000 Megabytes of data.
256000 divided by 45 equals 5699.88 seconds. Divide by 60 gives you 94.81 minutes. Or nearly 1 hour 35 minutes.
So how does that compare to a new Mac with SSD’s?
Compare it to 250GB of data on a newer Mac with SSD drives.
256000 Megabytes of data divided by 118 gives you 2169.49 seconds. Or a shade over 36 minutes to backup on a WD My Passport for Mac.
