Need help comparing two microSD cards...

[r00tb33r]

64GB models...

Versus this:

I have both, but I seem to be hitting the speed limit of my USB adapter, I'm getting similar read and write speeds on both.

 

What are some other easy/accessible ways for me to benchmark these cards?  Something with minimum setup to run tests.

 

I intend to use them in a DAP, and possibly a Raspberry Pi (model 3B+).

Get a higer speed SD reader?
 

If your planning on testing it on the Pi? If its limited by the bus speed on there it doesn't really mater which one is faster?

What about the endurance of the flash memory cells?  SBCs can wear out microSD cards.

 

I have difficulty finding complete info to compare these as Elite is newer than the (original) Superior, but the Superior is theoretically positioned higher in terms of market segment (and price).

 

Probably not going to get more USB SD adapters, I have a few but none of them are performant as far as I know.  You are welcome to suggest other devices like built-in SD readers in laptops, or smartphones?  Are those more performant?

Seems the easiest way out here will be to trust the A2 rating for IOPS, which should be favorable for SBCs.

 

In the past I never really had to compare these because I just used what I had without the luxury of choice.

Yes A2 is good for Rpi

If this is for a Raspberry Pi boot drive, you want endurance over raw speed. (Especially if you're leaving default behavior in place, so system logs etc are getting written to it.)
