I'm looking to upgrade the Hard Drive to a larger SSD

Please can you advise me on the Hard Drive upgrade options for this computer? Thank you.

@Chris2317,

Welcome to our HP user Forum!

Your HP Pavilion All-in-One - 27-a275na PC (Z7B90EA), according to: https://support.hp.com/us-en/document/c05360665, is fitted with a Palau-UF motherboard (SSID: 82DC) and has one M.2 2242 SATA SSD slot fitted with a 128GB Sandisk SD8SMAT-128G-1006 drive, and a 1TB 3.5-inch SATA 7200 rpm HDD drive.

I don't see any reason* why the M.2 2242 SATA drive couldn't be swappable with a larger capacity drive, such as this 1TB M.2 2242 SATA SSD purchase option: Amazon.com: SSD 1TB M.2 2242 NGFF SSHARKSPEED SATA 3 42mm 6Gb/s 3D NAND Internal Solid State Drive f....

The 1TB 3.5" SATA HDD could be upgraded with either a larger capacity 3.5" SATA HDD (2TB, 4TB) or with a larger capacity 2.5" SSD (need  a converter like this one: Amazon.com: Fenlink 6GB 2.5in to 3.5in Internal SSD Hard Drive SATA Drive Converter : Electronics).

* Some claim the M.2 2242 SATA drive's max capacity is 128GB.  Couldn't find any information online that would confirm this.

Hope this was helpful.

Kind Regards,
