trying to find info on the internal slots of my hp elitebook

nanaki · July 23, 2018

Alright so im trying to find out if both of the slots in my hp elitebook 840 g1 are ssd compat i know one is because it is uh marked ssd but the other is not.

Don't have a camera handy so just found this on the web noye the ssd slot and the 1 directly above it

As you can see the one above the ssd is meant for mobile broadband and is a exact (seems to be exact) mirror image of the ssd. Queton is can a dual slot m.2 ssd fit in both of these slots and work? If ths is the case im thinking of grabbing up 2x 32 gb m.2 ssds and using raid 0 on them then installing my linux to this (minus home dir which would go on a mechanical 1tb hdd) as my boot drive. Basically i want to just put every thing that is basically static data on the ssd raid array and all else on the 1tb hd. If the answer is no ill just buy the fasted m.2 32 gb ssd i can find and run the same set up with out raid. Raid 0 is more me wantign to fool around and see how stupid fast i can get my boot times. Right now im running 8 seconds or less to the desktop so uh yeh quite speedy already and that is with my intel pro sata 180 gb ssd. As this is a used ssd in a used machine i obviously do not want to rely on it for the long term so am looking at replacements for its likely sooner rather than later failure. Current reading on life of drive as seen by linux is 91%

Why would you do that? It's impractical and you wouldn't have wifi. Just get either a bigger 2.5" SSD or a single M.2 SSD.

I rarely if ever use wifi and the laptop actually has 3 slots one with the wifi card one for wwan and one for m.2 ssd. In my case it is more a why the heck not just for fun. How ever even as cheap as i can get these ssd it would be a bit of wasted money to buy 2 and not have em work. Though i suppose with the easy of access to this systems internals i could put 1 os on 1 and another on the other so not a waste i suppose. As for bigger ssd in the sata im looking to make my ssd last basically for ever or as close to as is possible. After all with basically 90% of all data on the ssd being just stuff that never changes my life expectancy of the ssd will be just nuts.

My goals with this little machine is large mechanical drive for videos and stuff that changes often os data that never changes on the ssd a ram drive where movies or what ever get copied to on load (looking to get as high of battery life as is possible going to get the slice battery that adds about 12 hours to battery life). Because the price of ssds of this type in the smaller sizes have come down the fact the slice battery is so cheap etc this is a why not experiment more than a oh god i must have this and only this need . I just want to see what is possible to pull off. This machine is already a very very capable machine even though slightly older.

As configured with ssd only its internal battery and setting screen brightness to 30% i can already get a bit over 6 hours battery life and 8 second boots. My end goal is something close to half the boot time and 2x battery life. 2x battery life with the slice battery is a absolute given half the time to boot is a pipe dream but say 90% faster should be doable if i can raid 0 2x 32 gb m.2 ssd drives.
