Libra 2 I changed the sdcard of my Kobo Libra 2 - Page 3

The Sage has eMMC storage not a removable µSD card so you would need a surface mount rework station to even think about removing/replacing the internal storage. The original N905 Touch, N514 Aura, N709 Aura One & N782 Forma also have fixed internal storage.

Makes sense. I'm too lazy to do all that and I'm only messing with smd if it's already broken lol.

Not that it was needed but I went ahead and recorded the process from the original post.

Used a laminated card (cut to fit)

sim card pin thing, worked easy once I bent it.

I now have 128gb!

Thanks for the info. It does seem strange that an older device is harder to modify than a later one.

From your second video, looks like the Libra 2 comes with a 32GB A2 MicroSD Card. Being that it's already an A2 card, would swapping it out for another card even help with performance?

IT would not help with performance. The only thing swapping the microSD card would do is give you a backup and more storage.

The only reason to upgrade would be if you've had a super extensive ebook library and want to take it with you all the time. I checked my Calibre library, and it's 7.2 GB in total, which includes some manga from HumbleBundle.

Sideloading audiobooks on the Kobo is a pretty shit experience. So if you only take Kobo native audiobooks into consideration, you probably still don't need more storage. Unless you're preparing for some sort of end of the civilization scenario, in which case an audiobook library would probably be your least concern.

From experience over the years, using a µSD card with better small block performance does help. You may remember the discussions a few years back where SanDisk and Samsung were my recommendations since they seemed to have the best overall small block performance. Too many of the high speed SD cards are optimized for video streaming and small block performance sucks.

A2 is current the fastest type of microSD card. So replacing one A2 card for another A2 card won't make any noticeable speed difference.

A2 can mean a lot though. E.g. Sandisk Extreme Pro V30 (UHS-I class) has a read speed of 170 MB/s. Delkin Devices Power V90 UHS-II has read speeds of 300 MB/s.

And once again, it's the small block read/write speeds that matter most in my testing. Oddly, that specification never seems to be mentioned by the manufacturer.

This is a message from 10 years back where I included test results from 3 different cards. Note especially the differences in the small block write results.

But what's the difference with these two microSD cards with small files? Those speeds are nowt what I'd expect to get in a Libra 2.

I don't know if TS is still around here, but I just wanted to thank you for posting these instructions back in 2022

This was obviously three years ago, so I don't know if you'll even see this, but: thanks for this very useful guide - which I thought I should let you know was used by someone I paid to do this for me (local tech guy). All went very smoothly, apparently.

I have one problem, though, which I wondered if you encountered, and if so maybe have a fix for.

Basically, the more books I've loaded onto the device (not far of 20,000 in total - I know, I know... therapy is being sought!), the slower and more temperamental it has become, even though it now has bags of extra storage ("198.6 GB of 237.0 GB available").

Obviously, it makes sense for it to take a bit (a lot) longer for Calibre to detect books on the device when I plug it into my laptop, and I'm fine with that. But it just seems to struggle in various ways that I thought might be cured by expanding the storage. For example, when I add a book or two now, it quite often spontaneously reboots before waking up properly, and then fails to import the books that are added (I have to just plug it back in, let Calibre do its thing, and then unplug again, and just hope that this time it imports the books rather than rebooting).

In my very non-techy way, I'm assuming that Kobo's "operating system" on the device isn't designed to deal with so much data, even though there's still bags of room on the microSD card - and I still haven't got anywhere near the "24,000 books" advertised as being feasible with the original 32 GB storage... ? If so, is there any way of tweaking/recalibrating something within the Kobo system files so that it would stop grumbling?

Anyway, either way, thanks again for the very useful guide!

Charlotte-B · 06-17-2025, 10:28 PM

Of course, I realise it might just be that my device is somehow faulty...

PeterT · 06-17-2025, 11:54 PM

I can think of some possible issues.

I presume you're using calibre to manage the books on your device. What are you using as the save template in the Kobo driver configuration? I'd be concerned if this template placed a large number of files / directories in any one directory.

What is the size of the KoboReader.sqlite database?
