Hands on Dell Precision 7710

The Dell 4K OLED USB Type C monitor costs $5,000... FYI

 

This is absolutely crazy. How in the world would an interposer card increase the maximum bandwidth of a SATA interface?

 

I never said get OLED. But wow. Wonder if they still have burn in issues. For the chuck of Dinero, I wouldn't risk it.

My understanding is that this is not a normal SATA connector, there are extra pins/hookups to allow the PCIe interface to pass through if you use it with the interposer. I believe this is true for 7510/7710 only (not 5510). This was discussed early on with Dell-Mano_G (Precision product manager) in the press release thread.

 

http://forum.notebookreview.com/thr...ns-press-release.782179/page-14#post-10122540 by Dell-Mano_G: “The 2.5" bay is able to support both 2.5" SATA 3 and via an interposer a M.2 PCIe NVMeconnected to PCIe lanes. Dual mode slot

This means that I can have 3 x Samsung 950 Pro, which is great.

If someone could confirm it would be helpful.

 

If I knew. I'll go back and find my question to him. Maybe I misunderstood his reply

 

If there are additional pins / connectors there, this could work. It means there are effectively three PCIe ports in the 7710.

*I'm slow this morning, I didn't see asalcedo's post above mine who posted the same. I think Bokeh has three PCIe drives in a 7710 and should be able to confirm or deny if this is true about the 2.5" bay.

 

Yep. There is an interposer card that allows the use of the M.2 card in the 2.5" bay. I had to borrow a PM951 from another system to add to the pair of SM951s that came with the 7710. It did work with 3 M.2 drives in RAID0, but in the end, I needed to put the PM951 back in the other system.

In response to the speed question on pair of SM951 drives in RAID0 - I set the stripe size at the recommended size, which I think was 4k. That may be the reason I am not seeing 2X the speed from the drives. It may be faster with 128K stripes. I am seeing ~3150MB/s reads, so I am not complaining.

 

Thank you Bokeh for the confirmation. Most helpful.

Concerning the stripe size, I have worked on this issue in the past.

It seems it does not matter much and lower are better:

One question, do you have performance figures for the 3 x PM951 in Raid 0?
