VPCZ13M9E/B: Maximum sd size card slot?

The VPCZ13M9E/B has a built-in card reader, supporting the following formats: MS, MS PRO, SD, SDHC, SDXC. Also a microSD would fit with an adapter.

How much it's the maximum sd size, or it depends just on the operating system?

 

To warrant 'SDXC' label it has to conform to its specifications, so 2TB in theory. However, the largest card available today is 'only' 512GB.

OS support of the card itself is no concern, although all SDXCs are factory-formatted as exFAT, which isn't widely supported beyond Windows. For better compatibility on Mac, Linux, cameras, mp3 players, media centres et al (everything else, really) better format to FAT32; its support is mandatory on SDHC-capable devices (use FAT32 Format for this). Drawback is the 4GB/file limit, which exFAT doesn't have.

 

Thanks for the input. The idea of using a big sd is to increase the Sony Vaio Z1 capacity. Since it's only 128GB SSD internal memory, I need to remove the dvd reader to install another internal unit. Using an SD would suffice for standard usage (although not as fast as SSD, in case you use virtual machines, gaming, video editing or alike). It will perform the same but slower I guess. It may depend also on the speed which the sd port connects to the motherboard.

About filesystems, some modern smartphones already support exFAT out of the box, and being root you can use exfat and ntfs, either on external sd or via OTG.

You'll need to play around with drivers and settings etc. The SD card reader does not eject the card sometimes. I have had to shut down the laptop in order to safely remove the card.

There is a nice utility - Zentimo xStorage Manager - which might help. However, if you want this SD card to increase permanent storage capacity, this issue might not bother you at all.
