T480: Installation of M.2 SSD 512GB using WWAN port

2018-04-16, 19:24 PM

Will the T480 support installation of M.2 SSD 512GB using the WWAN port which in my case isn't being used and is currently empty?

As I pointed out in that linked thread, it doesn't help you.  Repeating here for other readers:

 

The P51s m.2 WWAN/SSD slot is SATA.  The T480 m.2 slot is PCIe.  The Transcend TMS400 is SATA.  It won't work in the the T480's m.2 slot.

However, the T480 base spec does indicate that a PCIe SSD should work:

 

Some: 128GB M.2 SSD / PCIe NVMe, PCIe 3.0 x 2, 16Gb/s,
in WWAN slot as 2nd Storage, mutually exclusive with WWAN

 

The 128GB mentioned is the size that Lenovo will supply in that slot, not the maximum supported.  I'd expect higher-capacity drives to work, but haven't personally tested.

Would you know what brand of SSD PCIe-NVMe M.2 2242 is being used by Lenovo? Asking since looking around it's not that easy to find 2242 formats. Asking since I'm realizing that the WWAN slot only accepts x2 versions of SSD PCIe-NVMe M.2 2242 when looking what the differens are for x2, x4, etc (https://www.ramcity.com.au/blog/m.2-ssd-guide-compatibility-list).

Hello: Here is my issue: 

 

1. I have a T520 in which i plugged in an mSata SSD into the WWAN port  under the keyboard.  It appears like this MSata (thought SATA 3) is plugged into a WWAN which supports only upto to SATA II (i.e. 3GBPS) as it is showing now.  Not SATA III (6 GBPS which the disk is capable of - Samsung 860 EVO mSATA).  So, it is slow but faster than regular rotational disk.

 

2. I am planning to buy T480 or T580.  It appears like these two machines support one ssd disk connected to PCIe and a WWAN slot for M-2 SSD which support SATA also.  Is this understanding correct? If so, is the WWAN port giving me SATA 2 or SATA 3 speeds when I plug in a M-2 ssd into it?  Or is the WWAN giving me PCIe speed?

No.  As I indicated in the post you quoted, and as shown in the base spec:  The main bay can take a 2.5" SATA 6GB/s HDD or SSD. It can also take a 2280 m.2 PCIe/NVMe SSD.  Those are purchase-time options that can be changed after-the-fact with appropriate brackets and cables.

 

The WWAN slot can take a PCIe/NVMe m.2 2242 SSD. That slot does not support SATA.

Thank you for the reminder about PCIe/NVMe. 

 

Does anyone have experience with the MyDigitalSSD 42mm SBXe in the WWAN slot of the T480?  It's available both at NewEgg and Amazon, but there are no reviews.  I don't mind that it's Gen3 x2 and not Gen3 x4.  It would just be nice to be able to expand the storage in my T480.
