Compatibility of larger NVME M.2 device?

[Boomer561]

Hi, I'm inquiring here about the compatibility of the larger NVMe M.2 SSD.

I am mostly interested in the 1 TB internal SSD.

My device:
- HP EliteDesk 800 35W G3 Desktop Mini PC
- Product 2WV58EC
- Serial [Personal Information Removed]

Processor Intel Core i5-6500T. So it is a 35 watt version, equipped with a 65W voltage source.

I'm asking about this because I'm not an expert with this type of computer.

Based on the search results I gathered, here are the HP EliteDesk 800 G3 DM mini 35W M.2 slot specifications:

Form factor: M.2 2280 M key (PCIe x4)
Interface: PCIe 3.0 x4
Key: M key (supports NVMe SSDs)
Capacity: Supports up to 1 TB SSDs
Speed: Up to 32 Gb/s (PCIe 3.0 x4)
Power: Supports up to 12 W power consumption

In addition, the M.2 slot is designed for NVMe SSDs and supports:

SATA III (6 Gb/s) compatibility with older SSDs PCIe 3.0 x4 for faster NVMe SSDs.

Note ! This information is based on the search results I found and may not be exhaustive or up-to-date.

I have already received an answer from some different sellers that there is no chance
to install  this type of memory.

On the other hand, the sellers have also told me that there is a place for an SSD in my machine, but there is no information about the compatibility of a larger memory.

A 256 GB internal SSD is currently installed.

Information about the installed and used SSD:

HP P/N: 862996-003
Samsung Electronics CO., LTD.
Model: UGLHQ0129BB0HB
MSIP-REM-SEC-MZ-VLW1T00
pm961 nvmE

It works perfectly.

Located under the hard drive caddy for 2.5" hard drives.

Does this device support use of  larger, 1 TB,  NVMe M.2 based SSD?

Greetings @Boomer561 

Welcome back to the Forum.

Thanks for all of the provided details.

I don't see any reason why you can't swap in a higher capacity (1TB, 2TB, or 4TB) Key M, 2280 M.2 PCIe NVME drive.

Windows 10, 64 bit, supports high capacity system drives when using GPT. MBR would limit the system partition to 2TB, but you could do a 4TB drive with two partitions.
