Libra 2 Rev 3 Slow SD Card

Interesting about the Raspberry Pi SD card. I want to try it, but I only found it from one seller on Aliexpress ( ( Only a 64 GB card, he doesn't have 128.

It'll cost you more but you can purchase Raspberry Pi SD cards from places such as PiShop or Canakit (since I'm in Canada, I went with in-country suppliers). Currently, I'm using a 256GB SanDisk High Endurance card in a Pi 5 since I wanted the extra storage.

The seller on Aliexpress questionable to me, the reviews are good, but still... I'm looking at analogs, there are a lot of tests, which SD cards are recommended for Raspberry Pi. Based on the fact that they should be perfect for Kobo.
I'm currently using SanDisk Extreme Pro.

When I was doing more testing on µSD cards and their small block speeds, SanDisk and Samsung were consistently the best performers. One sad case was a class 10 32GB Patriot card where the small block write speeds were ~15KB per second compared to 32GB SanDisk and 32GB Samsung cards where the small block write speeds were in the 1-2MB per second range.

The two attached images are for two 32GB µSD cards. A SanDisk which shows as 29GB and a Samsung which shows as 30GB. Both cards are class U-1 (50MB/S).

I want to put 64 GB or 128 GB on Libra 2, I choose a card))
I would like to see the results of the Raspberry Pi SD card. It's difficult for me to order it, but if everything is absolutely wonderful there, then why not.

The Raspberry Pi SD cards as near as I can tell are high endurance cards. Linux is absolutely enthused with reading/writing small blocks of data so the high endurance makes sense. I understand that the Raspberry Pi branded µSD cards are manufactured by Longsys (also using the Lexar brand name) tested for compatibility, etc. but going by the specifications, any decent brand name A2 µSD card with CQ support will work. The high endurance cards will simply work longer.

Took a while to dig this link out of my collection mentioning SanDisk & Raspberry Pi but found this item:

One issue with putting a larger µSD card in a Kobo ereader is that when you start getting larger numbers of books on the ereader, the database size increases and can easily exceed the RAM size which does slow down some functions such as searching (I noticed this when I had >12,000 ePubs on my Clara HD).

In fact, this is a whim, there is practically no point in installing a card of this size to an e-reader.

Sounds like my reason for installing a 128GB card in my Clara HD. No worry about is it practical, just can I do this?
