StorageReview posted a review on the Dell PowerEdge R760
A quote from the article:
The Dell PowerEdge R760 is 2U rackmount server supporting two 4th generation Intel Xeon processors and up to 24 NVMe drives, including platforms that support the new EDSFF E3.S SSDs. Incidentally, E3.S SSDs are the only Gen5 form factor Dell supports on this platform, the U.2 bays are Gen4 only. The new form factors are making the decision tree that much more critical when configuring a PowerEdge for specific use cases.Dell PowerEdge R760 Review
