T450 & T550 M2 SSD Compatibility

Looking at a laptop for personal use but not sure what to get between T550 and T450....to replace my X220

 

Just wanted to get information on M2 SSD compatibiltiy for these laptop...

 

I am guessing they both should be compatible with 2240 M2 SSD but just wanted to confirm to make sure that I can have 2 HDD

 

Currently on my X220 I have mPCI SSD to boot OS and using 2.5" SSD for data storage and wanted to do the same on one of these...

 

also if anyone want to put some input comparing T450 or T550 that would be great....

 

Still tossing between these 2 laptop, T450 or T550, T550 still seems to be still portable but never had 15" laptop so not sure how massive that would be....

 

Current work laptop is T440 so I should get used to T450 more so then T550.... i might get good use of extra screen estate......

 

Thanks for your input.

Re: T450 & T550 M2 SSD Compatibility

Officially Lenovo does not support M.2 SSD as a boot device.  M.2 SSD is only supported as a cache device, and then, only when it is configured that way as an option from Lenovo factory.  This is the official Lenovo support position.

 

I can tell you about my personal experience.  I have T550 and I ordered an aftermarket 256GB Transcend M.2 SSD to put in it.  There was no problem for BIOS to detect it, and I could easily install Win7 on it.  As long as I was actively using the system, there was no problem.  But whenever I left the system idle it would eventually BSOD with code F4, usually after 30-45 minutes.  My conclusion is that there must be some incompatibility between this SSD and T550.  There was not any firmware update on transcend's website that I could find, and I'm using the latest T550 BIOS already.  So I really have no idea what the problem could be.

 

Now I'm using the T550 with a single 2.5" 512GB samsung SSD and it is rock-solid reliable.  So definitely, my problem had something to do with the Transcend M.2 SSD.

Re: T450 & T550 M2 SSD Compatibility

Did the BSOD seem to line up with one of the idle timers?


This isn't great news - I can see a combo like this in my future Smiley Sad

 

Thanks for the info,

Not that I could tell.  The timing of the BSOD seemed somewhat random.  Sometimes it would happen after ~20 minutes, sometimes after ~2 hours, but usually between 30-45 minutes.  If I changed the idle timers (or even disabled them), it did not seem to change anything.

 

One other detail I forgot to mention.  After the BSOD and automatic reboot, POST would throw an error like "2100 M.2 detection error".  Warm boot would not fix that issue.  I had to cold boot to get BIOS to detect the M.2 SSD again.  So, it seemed the SSD controller was just dead until a power cycle.

Re: T450 & T550 M2 SSD Compatibility

Sure sounds like an SSD issue.  Some kind of idle-time trim or garbage collection mishap, maybe?

 

Were you able to try other units of the same model, or other manufacturer's M.2 SSDs?

Re: T450 & T550 M2 SSD Compatibility

Actually I ordered 2 of these Transcend M.2 SSDs (MTS400) and they both have the same problem.  And I tried multiple T550/W550s systems (which use same planar/BIOS).  When one of these drives is installed, the T550/W550s system has BSOD during idle.

 

Now I'm trying one of these SSDs in T450.

 

I don't have any other manufacturer's M.2 SSD to try...

Re: T450 & T550 M2 SSD Compatibility

I am using a ADATA M.2 SSD (128 GB, Premier Pro SP900), this one: http://www.amazon.com/ADATA-USA-Premier-0-85-Inch-ASP900NS34-128GM-C/dp/B00LBDJZBA No problems so far with it in combination with my W550s. Might be only the Transcend SSD thats problematic.

As you seem to have both T450 and T550,.... how much thicker is T550 ? Spec seems to be about 2mm thicker but just wanted to Know how it feels when you carry it lid closed......

The T550 is indeed about 1-2mm thicker than the T450.  However I don't really notice much difference in thickness or weight when carrying it around.  The biggest difference will come from which removable battery you chose (68 or 68+).  The 68+ is the extended battery which nearly doubles the thickness at the rear of the laptop.  But the battery life is incredible!
