I'm checking this mini pc https://www.acemagic.com/products/acemagic-ad08-intel-core-i9-11900h-mini-pc

It says the M2 and SATA ports are limited to 2TB, but I can't imagine why that's the case.
Could there be a limit on the motherboard? On the CPU?
If most likely this is done in software (windows) probably it won't matter since I'm planning to switch to linux.

What I want to avoid is buying it and being unable to use an 8TB drive.

This undercover warranty investigation is a one-year follow-up from our series that investigated ASUS for motherboards incinerating AMD CPUs, at the end of which ASUS promised a number of improvements to its then-anti-consumer warranty processes. Spoiler alert: They're still anti-consumer. We sent our ASUS ROG Ally Z1 Extreme in for warranty repair for issues with the left joystick ("drift"). The device also had a broken microSD card. ASUS then pointed to the world's tiniest scratch and tried to charge us $200 for it under threat of sending back a disassembled device if we didn't pay within 5 days. It felt like extortion. If you're wondering whether ASUS is worth buying, the answer for anyone who values support should be "no."

We have now tested ASUS' motherboard and ROG Ally warranty and RMA processes. Both have been anti-consumer experiences.
