A:Answer It is not an answer, but specific question, based on your unfortunate experience - I also failed to find specific information about the exact characteristics of the drives inside. I want to upgrade, but don't know what to buy.
One option is to upgrade with normal SATA drives on both places. Are both drive slots identical? Is there physical place to install normal SATA SSD on the 128Gb place?
Other option is to try to upgrade with M2 on both places - But, can I install NVMe M2 SSD in both drive 1 and drive 2?
Thanks a lot!
