Question What microSD to choose for booting an OS on Baytrail Tablet?

[noob404]

I am planning to boot a lite OS like Lubuntu or XFCE from microSD (on the internal reader) on my Baytrail tablet. Though I have been able to boot, it's really slow. I ran benchmark on my current microSD card (Class 10) on the tablet with Linux and it gives me avg write speed of 12MB/s and avg read speed of 23.1MB/s with a sample size of 50MB.
To run the OS better, I am planning to get a microSD. These are the shortlisted ones:-
HP mSDXC U3 A1 64GB: https://www.amazon.in/HP-MicroSD-GB-High-Speed-Records/dp/B07TZ3XBXR/
Samsung Evo mSDXC U3 64GB: https://www.amazon.in/Samsung-MicroSDXC-Memory-Adapter-MB-MP64GA/dp/B06Y643ZC1/

Which one should I get for the purpose?

I would highly doubt that a Bay Trail Atom tablet, would even possess the hardware to talk to an SD (microSD) card at U3 speeds. Chances are, the card reader is an SDIO or USB2.0 device, and pretty limited. These weren't high-end machines.

Hey thanks for the reply. Is there any way to check without actually having the U3 memory card?

Modern PC hardware seldom offers latest SD card standards(or even at all). The reason Bay Trail has SDIO is because its mobile-oriented. Even the 300 series chipset has a passion mention of SDXC only in datasheets.

Bay Trail hardware can support SDIO 3.0/SD 3.0/eMMC 4.51 and USB Superspeed 3.0.

Looks like SD 3.0 is a term for which includes SD Class 10 speed and UHS-I. Another document says Bay Trail supports UHS-I with DDR50.

But some are saying Bay Trail has a bug with UHS-I so it would be wise for you to check what your device actually supports. Manufacturers are also known to not fully implement all the features available in the hardware.

I don't know Linux but in Windows you can use HWInfo to check supported features. The best would be to ask the manufacturer to in the forums? I know its not ideal but the device is old and outdated.

You also want to remember implementation is almost as important as the interface. I have a "USB 3.0" usb drive and it does not transfer at anywhere near the theoretical transfer rate. And I don't mean its at 50%, it probably gets something like 10% of the speeds and not much faster than USB 2.0 device I have.
