updated compatability list
Any m.2 sata card
Helix 2 ships with a range of cards, for those who are unlucky like me and got a sierra em7345 card which is a buggy extremely unreliable card that only worked 40% of the time. Lucky unlike past lenovo products, the helix 2 isn't locked down to a specific card. I installed the sierra em7455 card and haven't had a problem since, had to make a gps antenna though. Please note, after installing any card, even if windows recognizes it from the start, it won't work till you install official driver package and/or your carriers firmware. till then it'll claim there's no sim installed.
known wwan cards to work well;
Known not working devices
Sierra EM7345 works 40% of the time, and what's pathetic is this is the primary card they ship in the helix 2. in fact avoid any wwan card that's based on intel chipsets, none of them work reliably at this point. qualcom based devices work great.
Samsung nvme and pro. recently the pro was tested and found not to work. thanks elmsleigh for reporting the results of your test.

Just for completeness' sake I found a 950 Pro 256GB retail SSD and found that it works as advised. And yes it does seem to be much quicker than the original LiteOn 128GB SSD. Thank you all!

I have run across a lot of sites with bad information, makes me wonder about the motivations of the author.
Lenovo does use whitelists but the mini PCI Express slot and hard disk bay are not blocked so you can install as much sorages as you can afford

I know, the thread is very old.
I have the chance to buy one with a PCIe disk; though I found quite a number of posts elsewhere warning, that battery life would suffer from PCIe disks.
Can anyone please comment on this aspect?

Well your question kinda makes no sense, because that's what the device uses for a hard drive when it ships from factory is a pcie drive and there's no room inside for a standard hard drive of any sort. It'll run on any pcie drive you install as long as it's not an nvme drive. [and is the right length to fit in the slot ]
Swapping it for a larger one does not effect battery life.

I gave mine to my brother, but prior to giving it to him I had upgraded it with a 1tb drive. originally shipped with a 128. No change in battery life. So even if it did effect the battery life in some way it's not enough to worry with because even after the upgrade I still averaged 6-10 hours depending on my usage. Do keep in mind I also had the pro keyboard which has an additional battery built in to expand your battery life, without it battery life is typically 4 hours or less, but again I had no noticable effect on the device.

bumping this...so it seems like NO M.2 NVME drives work w/ helix 2? Seems like ONLY the Samsung 950 Pro NVMe PCIe will work (as far as NVME drives go)? In addition to ANY SATA based M.2?
That sound right?
I'm confused by this statement:
"So based on everyones testing so far and my own research, the helix 2 does not support nvme devices for booting, only sata which means the nvme evo devices won't work. However it appears retail pro devices do work."
So bstone108 is saying in the first sentence that the helix 2 does not support NVME devices for booting...but then in the second sentence, he appears to contradict this and say that "retail pro devices do work..." What is the case? NO NVME devices work? Or only the Samsung 950 Pro NVME???
