MicroSD vs Flash Drive

I’ve just purchase a new Dell notebook for work and I would like to attach storage to it that I can remove easily to store personal files, videos and photos on.

The Dell notebook has an integrated PCIe MicroSD card reader and I’m confused about what would be my best option for secondary storage, microsd or flash drive.

Comparing the SanDisk Ultra Fit USB 3.1 Flash Drive to the SanDisk Extreme® PRO microSDXC™ UHS-I CARD the read speed of the microSD is significantly faster but I cannot compare the write speed as it’s not specified for the Flash Drive (it just says 15x faster than USB 2.0).

Are there any other consideration for choosing Flash Drive over MicroSD? Do they have different latencies, small-block random I/O performance etc.



The flash drive is way better than a MicroSD. It has a great read/write speed, without any doubt you can go with flash drive.
