SSD on Acer Aspire Z24-880 Do you know the steps to open the PC and install the SSD?

These are the specs for the Z24-880 AIO hard drives that are - 1x SATA-3 B&M end key type M.2 2280mm SSD drives and the 1x 2.5" SATA-3 type drive mechanical HDD or it can be also upgraded to a quicker 2.5" SSD SATA 3 drives. For best performance also run adequate ram as this Z24-880 AIO can have a max total of 32GB (2x 16GB DDR4-2400MHz DDR4 1.2V SODIMMs type ram) into its 2x ram slots

Make sure that you update windows updates and all Intel drivers and if you have an NVidia gpu then update the gpu’s driver to its latest driver version, and also update to the last bios Version: R01-B2, be careful with the bios update, as and if you don’t know how to update a bios, get an experienced technician to this for you, as making a mistake with a bios update can brick your AIO PC, as and by doing all the above, it will make your AIO Z24-880 perform to its ultimate and best performance.

See below how to open the case of your AIO computer and where the M.2 2280 SSD drive is and the 2.5"HDD is, follow the instructions to open especially the DVD drive pre removal components from the Z24-880s case pre-opening.

Note: the capacities of the listed M.2 SATA drives at 128GB or 256GB capacities drives is only listed as a suggestion for this old AIO PC, as the SATA-3 drives capacity are only limited by their formats and the Z24-880 bios is a GUID Partition Table (GPT) UEFI partion this AIOs drive capacity can be from a range and to a greater capacity of 8 Petabyte plus (1 Petabyte = 1000TB) while the MBR/Legacy format is limited to 2,2TB max and that is the difference.

To disassemble do this:

1. Remove the four screws securing the computer stand to the main chassis assembly.
2. Detach the computer stand from the main chassis assembly, unscrew the .
3. Force eject the ODD tray by inserting a thin metal object or a flattened paper clip into the ODD emergency eject hole and push until the door opens
4. Disengage the latch securing the ODD bezel to the ODD tray, then detach the ODD bezel
5. Push back the ODD tray until it latches into place.
6. Remove the three screws securing the main cover assembly to the main chassis assembly.
7. Disengage the latches securing the main cover assembly to the main chassis assembly.

7. Detach the main cover assembly from the main chassis assembly

No, there is no maximum size, the 128 and 256GB sizes are just the options shipped originally with the models.

The drive interface is an M.2 PCIe x1 slot with support for SATA SSDs. Windows has a limit to drive size of 18 exabytes, which is much larger than any drive available. I expect manufacturers will stop releasing SATA versions of the M.2 form factor drives at some point. I believe that 2TB drives are available and that 4TB drives aren't in that form factor. The newer NVMe drives do have 4TB and 8TB drives in the M.2 form factor, but that's not compaible with your Z24-880.

That doesn't seem to be an M.2 drive, but I don't read Italian, so take my info with that in mind. :)

I'm happy. SSD improves computer performance.

You likely only need the HDD cable.
