The Best MicroSD Cards for Your Camera, Switch, and More

First they came for the DDR5 RAM,
and I did not speak out,
because I was only interested in micro SD cards for my handhelds.
... Damn.

I've learned the hard way that there is an enormous difference between microSD cards in the amount of power they need. When it comes to putting audio recorders out in nature, that matters a lot.
As an example, I was just comparing my latest AudioMoth results with SanDisk Extreme 64GB cards compared with Samsung Pro Plus 128 GB cards last year.
In the same device, with the same dawn-dusk daytime recording settings, on the same three fully-charged Powerex rechargeable batteries, the Samsung card recorded for four days (11 GB) before flattening the batteries, while the SanDisk cards recorded for 12 days (44 GB) before the flattening the batteries.
Given that it takes a lot of time for me to get to these remote sites to deploy these recorders, this makes a big difference to how much data I get.

My old car had an SD card slot that you could play music from. But the new one has only USB-C ports. However, I learned that they will allow you to mount storage, so I bought a cheap USB-C micro SD reader, and later added a 90 degree adapter to keep it from getting knocked out.
Nice and tidy!
Works well. This is in an #Audi but I bet it will work in other cars.
Not really. The filesystem tools and operations are the usual ones, and indeed the image files that operating systems and whatnot are distributed as can be treated as mountable DASD volumes with md. So it's a simple matter of copying a filesystem tree in the very same way that one would do elsewhere, be that pax -r -w or cp -R -p or pcmanfm or whatever.
Things like the RPi Imager are simply bundling up all of the same stuff behind a GUI (and, for example, using their own code to do mostly the same as what newfs_msdos does). These dedicated tools aren't actually doing anything special, really. They're conveniences.
Indeed, the RPi Imager when built for Linux either simply shells out to run the mount and umount commands directly or palms everything off to UDisks2. On MacOS it's likewise just palming things off to Disk Arbitration.
I've never bothered with special software to write TF cards, myself. I just gpart them and and use dd; or newfs and then mount the volumes directly and use pax/cp to just copy stuff in.
Failure at unmount time, presuming that the software is just trying to do an actual unmount, pending writes having flushed pretty quickly presumably, has the smell of card fault or card reader age/fault about it.
I've had to retire at least one old reader because it couldn't handle HC and XC cards.
Wow, this is really interesting. I have 8 SD-cards, 4 x 256GB Samsung Evo Plus and 4 x 512GB Samsung Evo Select.
7 of those cards show big fluctions when transferring 200 to 300 GB videofiles off of them. But 1 card, the last one obviously, shows no fluctuations in transfer speed. It just stays maxed out.
Other factors are as equal as you get over multiple days and reboots.
So it does seem to be something about the SD-cards...
Yes, #eMMC is just a soldered-down #SDcard!

In this buyer-beware world that we (unfortunately) live in, I am very grateful for efforts like this
How can I tell which is going to last the best in a hard working Raspberry Pi?
I don't see any 'read/write cycles' data.

restarting virtual disk service causes this
for some reason our sd card causes virtual disk service to stall until we assign a drive letter to it and we cant assign a drive letter until we either reboot and use ext4fsd to assign a drive letter even though its not a linux file system or unplug the sd card
even restarting the virtual disk service doesn't fix it
if any want to help let me know
in the meanwhile you get a task failed successfully

Lexar’s SD 8.0 card support speeds up to 1700 MB/s, but there’s nothing to use it with
Lexar has introduced a new SD card with theoretical read speeds up to 1,700 MB/s and write speeds as high as 1,000 MB/s. But the word “theoretical” is doing a lot in that sentence, because right now there are no compatible devices on the market that will let you use the card at those speeds… and there might never be.
The new Lexar Profesional GOLD Pro SXDC Express Card is the first […]

Dear Lazyfedi:
I'm thinking about using #SDcards to store things for a long time (so, way more reads than writes). Are they better than #externaldisks (#ssd) in the long run?
Finally got hit by fraudulent SD Cards from Lazada. Tested with f3. Gonna see if Lazada does anything about it.
