I pre-ordered my FP3 yesterday and am getting ready to fit it with good supplemental accessories.
Of course I want a microSD card. Unfortunately, the specs on the website don’t tell if the controller supports A2 cards or just A1 (which is e.g. the difference between a SanDisk Ultra vs. an Extreme Pro).
No worries if it does just A1; it merely means I will be able to trade the A2 surplus price for capacity then.
Maybe someone from FP staff knows that amount of detail?
And just to be clear, with “supports” I mean “can make use of the extra features” - it’s totally clear that there is full backwards compatibility with A2 cards in a A1 controller. My question is specific to the usability of new features of A2 cards (especially Command Queueing, which needs controller-side cooperation).
Yeah full specs on the microSD card slot would be very useful. Doesn’t make sense to put a card with 160MB/s read speed into a reader that won’t go over 100MB/s.
Most important is that it works. If it could be faster in a different device, so be it.
Who knows beforehand which other devices with different specs a card will possibly see in its “life” .
Just my approach, of course.
Of course, it’s really not that important and I already ordered the FP3 without knowing the microSD specs. However it would be stupid to buy a high speed sd card “just in case” because there are no specs listed anywhere.
I for one have meanwhile bought a Class-3 A1 card as that is enough to record full HD video in sustained speed.
Thanks for the investigation nontheless!
I have an A2 model too and to no suprise it works. I still have no idea does it actually support the random write and read specs of an A2 model or does it work at slower speeds.
I also wonder about the maximum supported size. The specs say 400GB, however there are other product websites out there who say 200GB or don’t mention anything at all.
I expected the Snapdragon specs to define the maximum size and the supported version, but there is no mention on the qualcomm site.
As I am thinking about to change from an iPhone to the Fairphone I have not much information about using modern phones with SD cards, I just got to know from this thread and several pages that there different models.
I would highly appreciate a comment on which typ of card/model makes sense to use with a Fairphone 3.
I’m curious if there is any smartphone manufacturer going so far into details which specific sd card features are supported in their phones/controllers. Mostly I can read about maximum size and few times about speed class.
This also was a task of trial and error with the FP2. My first 128GB Samsung pro+ wasn’t always recognized after boot, but the slower evo+ works fine. Therefore the pro+ type was simply swallowed by a LG G4.
Hi,
I updated my MicroSD: SanDisk Extreme A2 512GB, microSDXC, Cl10, U3, V30.
Works for me. I don’t know if it is feasable to test how fast read/write is performed by the phone’s controller. If anyone needs that, I need a hint how to…
best
Stefan
