M.2 drive length for AiO HP EliteOne 800 G1 All-in-One PC

[pcTechs]

What is the m2 drive length of the m.2 m2 sata slot  in this AiO?  HP EliteOne 800 G1 All-in-One PC.

i have looked in the service manual and other manuals but it does not say the physical size of compatible drives?

this model AIO appears not to have had a official m.2 HP SSD option as the quickspec sheet only shows 1.8 ssd's  and 2.5in

however hp sometimes uses a motherboard in different models, and one of those models may have had a ssd option

this would explain why your board may have a m.2 for wireless and a ssd or the m.2 socket may be for a cache module, the HP quicspec sheet does mention a 32 cache module

hmmmm...........interesting the hp parts list for this model does list the interfaces as a MXM (video) wireless and mSATA

and if true you have a full sized mSATA and a Half Hight option  no other sizes exist the half option is aprox the same size as a half height wireless card

keep in mind that a m.2 connector is just that a connector, and it can be wired up as a hard drive (sata or nvme) or as a wireless only or as a cache module that speeds up a mech based HD (readyboost) and if used as a cache module may be wired up as a PCI interface

all of the above 3 examples can use the m.2 connector, but are not interchangeable between the different interfaces
