Apple Silicon, but not the true potential
of the drive. We tested the drive on
PCWorld’s testbed to get a clearer
picture of that. In total, the drive was
easily the fastest 10Gbps USB we’ve
tested as you’ll see below.
The CrystalDiskMark 6 tests run on
sister publication PCWorld’s test rig are
48GB real-world transfer tests.

The drive is preformatted to HFS+, but
you can reformat it to exFAT if you want to
share data with Windows machines, or
NTFS if you only write from Windows PCs.
SanDisk includes both Type-C to Type-C
and Type-C to Type-A USB cables.
WD didn’t provide a TBW rating.
However, the drive is warrantied for five
years, which is a nice bump up from the
more common three years.
PERFORMANCE
We haven’t been getting very good USB
performance out of our new 24-inch
iMac, so take the Disk Speed Test results
(shown below) as what you might see on
For whatever reason, USB 10Gbps
performance on the Macworld M1 iMac is
slower than it was on our Mini, which is
disappointing, as others have pointed out.
