Well, I guess there is no getting around the inevitable. If I choose to stay with Lenovo to replace my beloved W700 (which thankfully still works well after 5 years of service), there seems to be no alternative to the W540, clearly inferior in many respects to earlier machines. I echo the sentiments of all those who have decried Lenovo's apparent lack of insight into the needs of profession users who used to be the bread-and-butter customers of ThinkPads and who would gladly pay any necessary premium to obtain the best tools for their work.
Enough venting -- given that this new machine is of the two-spindle variety (I'm used to 3 in the W700), I could use some guidance:
Would it be possible to put a large Intel 530 or better M.2 SSD in this machine (360 GB or larger) and set it up as a boot drive, with the main HDD dedicated for storage? With a configuration like this, effectively a 3-spindle machine would be created. How might this be accomplished, both from a physical configuration perspective as well as an OS installation, etc?
I viewed the online Lenovo service training videos for this machine and found nearly no information on the mSATA slot or even where it might be located & accessed on this machine.
Your assistance would be gratefully accepted, fellow ThinkPad users.
Solved! Go to Solution.

Ditto what Biznatch says. I too am doing this on the W520. The mSATA slot on the W540 is supposedly SATA 3 - so much the better.
Crucial and Mushkin offer 480GB mSATA SSDs, Samsung has a 512GB (not over provisioned) you can get through Amazon.
On the other hand, Crucial has a 960GB SSD for $530 (street price). So perhaps three drives are no longer required.

There are multiple m.2 formats. I'd like to find out whether the interface is SATA or PCIE. The SATA interface has two notches, and the PCIE has a single notch. The difference in performance is dramatic; so I'm hoping for the PCIE version.

Note: from Page137 of User's Guide:
General tips for preventing problems
• If your computer is equipped with both a hard disk drive and an M.2 solid-state drive, you are not
recommended to use the M.2 solid-state drive as a bootable device. The M.2 solid-state drive is designed
and developed for “cache” function purpose only. If you use the M.2 solid-state drive as a bootable
device, its reliability is not guaranteed.
No information that I could find in either of these documents which answers the question of mSATA or PCIe -- or describes card length specs.
....Do you ever get the feeling that Lenovo doesn't have a clue about how serious users would like to use their products?
