Before the much-needed overhaul, there was definitely something wrong with how Apple handled write operations on UFDs. Apple also has made significant improvements to USB drive performance on iPadOS, bringing it up to par with that of Windows. If backing up photos is a daily task, Lexar JumpDrive D400 is quite a bit faster than the other five drives.īeginning with iPadOS 15, a progress bar is introduced in iPadOS’ Files app to indicate the amount of data being copied and the remaining time needed for the file transfer to complete. For this set of benchmarks, we repeated the same copying process with the same files we used on the MacBook Pro earlier.įrom the graph above, the Kingston DataTraveler microDuo 3C (2022 model) led by a fair margin in read speeds. That said, dual flash drives tested are limited to 5Gbps (USB Gen 2 Gen 1). Next, we looked into the kind of performance you can expect if you plan on using these dual flash drives for regular photo backups and large video imports on an Apple iPad Pro. The 2021-model iPad Pro is equipped with USB-C capable of delivering 10Gbps through USB 3.2 Gen 2 and 40Gbps through USB4. Write speeds for every drive in the category, however, were fairly disappointing as the “fastest” one – Sandisk Ultra Dual Luxe – could only manage 33MB/s. Tests were carried out on Nodesoft’s DiskBench.įrom the graph above, Kingston DataTraveler microDuo 3C had a lead over the competitors with a read performance of around 200MB/s. We then repeated the process with a 5GB folder containing 1000 JPEGs. For our PC benchmark, our testing with the USB-C interface involved transferring a 9GB MP4 file back and forth between our MacBook Pro and the drives. We carried out our drive benchmarks on two different platforms – Windows 10 Pro running on MacBook Pro (2019) and iPadOS 16.4.1 running on Apple iPad Pro (2021).

But for the sake of convenience, these dual-head drives still have a place in some storage applications. Lexar JumpDrive D400 and Sandisk Ultra Dual Luxe have a write speed of around 30MB/s despite the fact that they are already quite a bit “faster” than the rest of the pack. Having said that, out of the six drives we tested, none of them is really made for heavy-duty use as their write speeds are simply too slow. Kingston DataTraveler microDuo 3C is our choice. It is the most compact of all dual-head flash drives and excels in read performance.
