Western Digital’s portable 2.5-inch HDDs are now available in 6TB variants.
The different drives feature similar specifications with minor connectivity and compatibility differences.
The standard Mac version also ships with a USB-C adapter, but its cable is USB-A.

Although only some models carry Mac labels, all of the drives can support macOS.
However, the Windows My Passport and My Passport Ultra must be formatted to work on Macs.
Using the Mac editions on Windows only requires downloading an HFS+ driver, with no reformatting required.
The standard Windows model also supports Chrome OS.
The primary difference is that it ships pre-formatted to exFAT.
One is bidirectional USB-C and the other is USB-C to USB-A.
It supports macOS out of the box and must be reformatted for use on Windows.
All of the 6TB drives feature a roughly 130MB/s sequential read performance and a 5Gb/s transfer rate.
