T450s m.2 SSD

2015-03-13, 17:03 PM

According to this website: http://www.pugetsystems.com/labs/articles/Overview-of-M-2-SSDs-586/

m.2 slot comes in different flavors (SATA III, PCI-E 2.0 x2, PCI-E 2.0 x4 and PCI-E 3.0 x4)

 

I would like to know what is the supported protocols for the T450s laptop.

 

I'm asking this questions becauce I would like to buy a m.2 SSD disk to replace the "too small" 16GB that I have and I would like to know if it's worthwhile buying the Samsung SM951 that supports PCI-E 3.0 x4.

 

Thank you.

Good day and welcome to the community.

 

Apologies that I can't answer the SATA vs PCI-E portion of your question with any certainty. I can say, though, that the SM951 won't fit physically in your machine. That SSD is a 22x80mm form factor (2280) while your machine takes the 22x42 form factor (2242).

 

Please have a look at your hardware manual:

http://download.lenovo.com/pccbbs/mobiles_pdf/t450s_hmm_en_sp40g54937.pdf

where manual page 66 describes removal / installation.

 

Then, have a look at the FRU BOM:

http://download.lenovo.com/parts/ThinkPad/t450s_frubom_20150126.pdf

and on the last page you'll see the only factory part listed is the 16GB M.2 2242 SSD normally used for caching (I believe).

 

You should still be able to install a higher capacity 2242 M.2 SSD in that slot, though. The largest M.2 2242 SSD I've seen is also 256GB, but I haven't searched exhaustively.

 

Hope this helps a bit.

Regards.

Re: T450s m.2 SSD

I don't have an answer to the PCI-e vs SATA question either :(  Some Lenovo machines support both protocols, but IIRC they use an 80mm card, and are intended as the main drive, not a cache.  (Not to say that you can't use the 42mm slot for a main drive, just that a slot intended for main drive use is more likely to support both, if that makes any sense...)

 

To further add to the (my) confusion, the T450s Base Specification says "Single-sided M.2 SSD, via M.2 card slot".  I haven't  been able to chase down information on whether the available 256GB drives are single- or double-sided.  It may or may not be an issue.

 

Apologies for not having clear answers.  I'm tossing this out there to indicate that there may be other issues to check into - and hoping someone who's actually done the swap will join the conversation.

 

Regards,

Z.

Thanks for the clarification on the 'single-sided' 2242 M.2 SSD, Z.

I missed that. :|

There's some positive discussion of T450s vs M.2 SSDs here:  http://www.mydigitaldiscount.com/m.2-ngff-ssd-compatibility-list.html

 

I have't used their products - and don't have a T450s :( - so I can't speak to the accuracy of the information.

Re: T450s m.2 SSD

I realized that the user guide specifies that OS should not be installed on the m.2 SSD....

 

"If your computer is equipped with bot hahard disk drive and an M.2 solid-state drive, do not use the M.2 solid-state drive asa bootable device. The M.2 solid-state drive is used for “cache” function and to support the Intel Rapid Start Technology."

http://download.lenovo.com/pccbbs/mobiles_pdf/t450s_ug_en.pdf

 

Well, I think I will go with a good "old" 2.5 inch SSD and stop bothering with this not so clear M.2 ssd.

 

Thank all for your help.

It's entirely your call, but I (and most others) read that Lenovo warning to apply to the factory M.2 SSD - which is too small to reasonably host the OS.

 

That warning has been in place going back to the mSATA cache drive days, and many users have swapped in a larger SSD for the OS.  That's how I run my T420 and it works very well.  I really like having a fast OS SSD and a 500GB spinner (set to spin down when idle).

And I wholeheartedly concur with Z!

 

My X220 sports a 256GB Crucial m4 mSATA under the keyboard, hosting the OS, temp, minimal swap and apps. Data was originally all on a fast (relatively speaking) 500GB Travelstar in the main bay. Now the main bay sports a very fast Samsung 840Pro. The machine has proven to be bullet proof for almost 3 years now.

 

Cheers.

Re: T450s m.2 SSD

2015-03-23, 20:13 PM
So, no one has been able to find any specifications from Lenovo about the possible interfaces, the m.2 keys or the sizes possible in the T450s chassi. As far as I could see, deductions from the bom, sprefs indicate:
* current fru in bom is a 2242, sata
* in the spref it mentions "Single-sided M.2 SSD", whatever that means.

Hmm, I'm just realising another deduction, based on http://www.pugetsystems.com/labs/articles/Overview-of-M-2-SSDs-586/#M_2logicalinterfaces - reading "In truth, the only time a M.2 drive won't work even through the keying matches is if you try to use a M.2 SATA drive in a M.2 to PCI-E adapter since it doesn't have a connection to the SATA controller." This would mean that as the FRU is a SATA drive, the T450s must use an M.2 SATA interface. Correct??
