SanDisk Extreme microsdxc fast enough?

wolframmitbach · May 3, 2020

Write speed for the SanDisk Extreme microsdxc is 90mbit/s MA 2 produces up to 120mbit/s - will this be a problem?
Shouldn't be the Lexar Professional 1000x 128GB microSDXC V60 better ?
Why does dji sell the SanDisk?

SanDisk is 90MB/s = 720mbits/s

Thanks for the comment / correction - sorry I used the wrong scale but the question remains: MA2 produces up to 120MB/s
SanDisk write only up to 90MB/s - any negative impact?

You are confusing Mbs with MBs. MA2 max bitrate is 120 Mb/s; which is 15 MB/s.

It’s a horrible naming convention having bits and bytes.

Almost as bad as tablespoons (Tsp) and teaspoons (tsp).

Speaking of which, what size do folks suggest? 32, 64, 128 Gb U3s (100MB/s)? My idea is to have two in hand rather than rely on a single card.

That depends on what you are going to use it for. Shoot all 4K/60 then get the biggest card you can.

Just snap shots? Then maybe a smaller card.

Up to you.

How much GB will 1.5 hrs of 4k/30and60 video use? All of 64GB? I only bought one 64gb, debating if I should also buy a 128gb
