Re: W540 -- mSATA as boot disk?

Not sure how I can measure that,  I just have a plain ruler and a empty slot.

 

Heck, even the 42mm is an educated guess, the slot is about 40 mm long and since the standards are 30mm, 42mm and 80mm, it has to be a 42mm slot.

 

But right now it's a moot point as I don't even see any m.2 drives for sale.

Re: W540 -- mSATA as boot disk?

Here's one of the Intel models for you from NewEgg but length is not specified -- probably too long.

 

http://www.newegg.com/Product/Product.aspx?Item=N82E16820167170

 

Intel does seem to offer some of its models in the correct length but I suspect you have already searched the web to find one:

 

http://ark.intel.com/m/products/78066/Intel-SSD-Pro-1500-Series-120GB-M_2-42mm-SATA-6Gbs-20nm-MLC

 

Leave it to Lenovo to screw us again with idiotic design compromises -- if it was an 80mm slot, we would be able to have many more options.  As of now, it seems that we will be capacity limited to 120 or perhaps 180 GB.

Re: W540 -- mSATA as boot disk?

You are correct. 

 

We are stuck moving up to the Intel 1500 series Pro models -- much harder to locate and probably more costly with little incremental benefits.

 

Other than that, Mrs. Lincoln, how did you like the play?

Re: W540 -- mSATA as boot disk?

Looks like MydigitalSSD SC2 has a 128GB version that's readily avialiable.

 

BTW, I found a Intel 1500 series 2.5" SSD in my W540.

Re: W540 -- mSATA as boot disk?

It seems the only M.2 SSD with 42mm is 120GB only Smiley Sad Smiley Sad

Are we certain about the length? I would love to use a 512/480GB model

Re: W540 -- mSATA as boot disk?

99.9% sure it's a 42mm slot, I'd post a picture but I don't think I can do it.

The standards are 30, 42 or 80. I think I can tell the difference.

 

Sir, are you questioning my skill with a ruler? Prepare to defend yourself! Robot Mad

Re: W540 -- mSATA as boot disk?

Hey,

I'm sure you know how to use a ruler - no offence Smiley Very Happy
All I'm sayin is thats it a little weird because it seems there are almost no 42mm M.2 SSDs out their. Which makes it kinda useless...

Maybe you can get an 80mm in their a little tilted Smiley Wink

Re: W540 -- mSATA as boot disk?

PS: I just checked my W520 about a mSATA card. It seems the mSATA and WWAN card uses the same slot. I have & use WWAN so I cant install mSATA...

Is it the same on the W540?

Re: W540 -- mSATA as boot disk?

No, the Wifi is M.2 as well

from the PSREF Sheet.

11ac, M.2 Card, Intel Dual Band Wireless-AC 7260, 2x2, Wi-Fi + BT combo adapter.

 

So the other free M.2 slot can be used by either WWAN or a M.2 SSD.
