    Ordering a T440p soon, but wanted to suss out what my options were for (bootable) m.2 SSDs.

    The maintenance manual doesn't specify what size the m.2 slots are, but the drawings seem to indicate that there are two sizes; presumably, one is 42mm and the other is 80mm? If the latter is indeed there, then this would presumably work:

    Intel Solid-State Drive 530 Series - Solid state drive - 180 GB - internal - PCI Express M.2 Card at TigerDirect.com

    ???

    Anyone have luck with installing and booting from an m.2 SSD in the T440p, and can confirm the dimensions, etc?

    I believe it's 42mm, which severely limits your M.2 SSD options. I'm not sure any Thinkpads come with an 80mm slot, which annoyed me no end and made me decide to use the ultrabay for a dual-drive setup on my T440p

    m,2 max length is 42. max size for now is 128gb.
    Intel plans on a 180gb version later this year.
    I wanted a triple-drive system so imagine how annoyed I am.
    I don't understand some divisions from lenovo. m.2 is new I get it, but why limit it to 42? They never considered either the msata or the m.2 as a proper drive only as a speed boost.. Their designers are getting confused.

    Agree... even the new W540 only has a 42mm slot as far as I know, and if any machine is deserving of a real card-based SSD then surely it's that one. Many other manufacturers seems to have stuck with mSATA, which at SATA3 speeds makes far more sense IMO

    So this can slot right into the WWAN slot, right?

    I'm considering picking up the 128GB SSD from Amazon and putting my Linux install on that... How are the speeds on these things?

    I have the mydigitalssd msata m.2 128 gb in and it is getting 500+ mbs read and 400 mbits+ write. It is blazing fast, and easy to install.

    How does it perform over time and under load? I've only ever seen basic test figures for initial speed, not a full review looking at all-round performance. I ended up opting for a dual-drive system using the ultrabay because the MyDigitalSSD was a relatively unknown entity (and the only option for an M.2 SSD over 100GB). I currently have a 240GB Intel 530 SSD I got for $100 (after rebate) in the main bay and a Travelstar 7K1000 in the ultrabay.

    Pretty decent -- ATO hasn't seen much loss it has the PHISON controller in it pretty decent.

    Looking at this review of the 128GB MyDigitalSSD, I'm concerned about the throughput:

    MyDigitalSSD 128GB 6G M.2 NGFF SSD (Mini Review) | TechPowerUp Forums

    Based on the numbers there, it's half as fast as the Samgsung 2.5" SSD. Perhaps it'd be best to use it as a backup destination, and continue using a 2.5" for the boot and primary partitions.

    I use it for storing my dropbox and box files so no real thrashing of it. But I am quite happy for the price, etc.
