PERFORMANCE:

The Transcend StoreJet 300 2TB for Mac Portable HDD is obviously designed and made for Mac users who would like to expand its storage. The device form factor is on 2.5-inch aluminium metal enclosure and the hard disk drive can be from Samsung/Segate with storage capacity up to 2TB of data/files. The file format of the StoreJet 300 is in HFS+ were totally different from FAT32 or NTFS that Windows PC have.

For the actual performances, the portable hard disk drive has a sequential read/write speed of 125 MB/s. This is due to the hard disk drive limits as the drive can run as fast as 5400 rpm. So don’t rely yet on the graph that you can see at the back of the box, that it can transfer up to 5Gb/s via USB 3.0 and up to 10Gb/s via Thunderbolt.

USING MACDRIVE TO TEST ON WINDOWS OS

If you are a Windows user, you can actually use the portable hard disk drive via MacDrive software.

Running some test with CrystalDiskMark via USB 2.0 slot

You got a decent sequential read speed of 30.66 MB/s and a sequential write speed of 32.54 MB/s.

HD Tune Pro via USB 2.0 slot

Same results I got from HD Tune Pro, the read speed is about 30 MB/s and a write speed is above 30 MB/s.

Real world transfer speed test: I used 692MB zip file to test the file transfer speed.
