Specifically Which model m.2 ship with precision 7000 series?

What are model and part #s of the M.2 PCIe NVMe SSDs that are shipping with the new precision 7000 series?

For that matter, if you have one of the new precision laptops that shipped with any drive, I am nterested in seeing what those brand and part numbers are. But in particular the SSDs, and even more so the M.2 that are shipped with the system

Thank you

 

M.2 1TB option (DP/N 0W53CK) came as PM951 NVMe Samsung 1024GB P/N MZVLV1T0HCJH-000D1 Model MZ-VLV1T0D

 

I have seen Samsung PM951 and SM951 drives.

 

which is the difference between PM and SM ?

in DELL customization you can choose two "kind" of M.2 PCIe drive: one of the two choice is named like "high performance" one. One side is "951" and the "high" is "950 pro"? or any other drive?

Thanks

My guess is, that the difference is PCIe vs. SATA connection. m.2 SATA is limited to ~550mb/s reads, while PCIe x4 goes beyond 2000mb/s

 

No, they are both 2000x. I mean this difference:

 

The only specific model I have seen anyone mention is PM951.

Dell will not commit to a specific model. They have set up performance "thresholds" for which drives may be used in the Precision and which ones qualify as "high performance" (we don't know what these thresholds are) and will ship any drive they have on hand that meets the criteria.

If you are looking for a specific model drive, you should plan on buying it separately and then sell off whatever comes with the system.

 

In a german price comparison machine you see both PM951 and SM951:

The specs look identical except for the speed, although both are listed as PCIe 3.0 x4

 

Thank you @SvenC , it seems there is not trascurable difference between PM and SM...

Thank you @Aaron44126 , understand. The model you heard mentioned (PM) was about under "high performance" in DeLL customizatin or not ?

 

Thank you all for your replies.

*edit: Seems that the Samsung SM951 is the "High Performance" M.2 PCIe 3.0 x4 NVMe
