HP cn2953nd in RAID1 mode or mirror

[Shurlock]

The laptop has an M.2 256Gb NVMe onboard.

I would like to replace that for a 1Tb  and  add a 1Tb SSD and set these to RAID1.

Or, if that is not possible in BIOS, set the SSD as mirror within Wondows 11.

(Of course I realize that the M.2 NVMe would probably be slower because of the SSD)

The BIOS are not going to allow for a RAID array. You could set it up as you describe. Then in Windows 11 disk management you can create a new mirrored volume on the SSD:

Creating a real time mirrored volume will not slow the system down much if at all. You will automatically have an exact backup of what is on the NVME M.2 SSD.

Thank you so much for your answer. Fact is that I was told that I could NOT place a (new) 1Tb M.2 AND a 1Tb SSD.

"The system will not support more than 1Tb".  My thought however, was that an SSD  mirror-drive  would not exceed  that maximum.

Of course I am eager to order these parts (including the SSD cable), but I would like to be sure before spending the money.

Thanks in advance for your response. 🙂

Not sure who told you that. May have been HP Support. They often mistakenly believe that one can't install storage larger than HP offered from the factory as shown in the Servide Manual.Not so. The M.2 and SATA storage slots can handle any sized storage devices on the market. There is no practical capacity limit. You could install 4 TB devices should you choose and if you can find them. 2 TBs are commonly available and would work.
