Need to order a replacement hard drive for HP Envy 27

This just uses a normal 3.5” drive in both the 2-3TB HD configurations, so anything will fit in place of the original drive. Refer to this guide to change the drive out. If you want to match the original drive, a replacement can be found here. You can also install an SSD, but you’ll need a 2.5>3.5” adapter since the caddy doesn’t look like it was designed with SSDs in mind on this machine. As far as the SSD goes, 256GB+ will suffice - pick the drive you want based on your budget.

If you want to install 2 drives and install your OS on an SSD, you will need to put a SSD in place of the optical drive, and then put the hard drive in the internal caddy - this computer doesn’t have the headroom in the form of a second internal SATA port dedicated to HD use, so you’ll need to choose between a large expensive SSD, or losing the optical drive and having large storage. You will need to transfer the OEM faceplate over unless the machine uses a “generic” one, or it won’t look right. With HP, it’s a wildcard situation with some doing it another way, or doing it externally where you have to move it.
