X250 M.2 Slot for Boot Device?

Good afternoon - 

 

I have seen some other posts that nearly address my question, but none directly.

 

On the x250 - there is the option for what Lenovo calls a "Micro Hard Drive".  It appears this is intended for caching data to improve general system performance - especially for those that have non-SSD drives.  The default size from Lenovo is 16Gb.

 

My question is the number, type and size of those slots.  Will a standard M.2 drive fit in those slots?  I saw another thread that talked about only using an M.2 size 2242.  My idea is to install a 128Gb M.2 SSD (if that capacity is available in that form factor) as the bootable OS disk.  I would then use the 500Gb HDD as a data drive, so to speak.

 

Is it possible to designate an SSD in one of those M.2 slots as the "boot" device?

 

Thanks in advance!

First, I don't have an x250 to test with. Starting with the "40" machines, there is an m2 slot that appears in the BIOS startup list as "disk 3". I use a W540 that also has an M2 size 2242 (22mm X 42mm). It came with nothing in the slot, and I put in a 256GB SSD and I boot from it. The one I bought, costs about $110 from Amazon.

Please note, I am not recommending a particular seller, but my drive works well for me, and Amazon has a good return policy.

That is good to know. I hope the same concept applies to the x250.

Thank you for the information.

I have the Transcend 2242 256GB M.2 SSD running as the boot device in my brand new X250.  Works great.

I too have it installed as my OS/application drive - works great.

 

Coming from a W520, I was skeptical of whether this X250 would do the job for me - but other than some speedbumps working with Lenovo support, the heardware itself has exceeded my expectations.

Re: X250 M.2 Slot for Boot Device?

Sir, I have Thinkpad x250 & recently install the Sierra EM7345 4G LTE WWAN card in the M.2 SSD slot by removing the SanDisk 16GB M.2 NGFF SATA card that came pre-installed. Then I purchased an external SSD case & inserted SanDisk 16GB & connected it via USB to improve caching performance, now I'm considering upgrading by replacing the 1TB HDD drive with M.2 SSD PCIe NVMe card (128GB or 256GB). Please advise me if PCIe/NVMe is compatible/supported by the system or only M.2 NGFF can be install in it's place for OS bootup? Thx.

Hello,

 

You can use any M.2 2242 SATA III SSD in the ThinkPad X250's WWAN M.2 slot.
