Nice!Yes there will be.
In 2020, as part of the U.3 transition, we discussed here https://www.servethehome.com/toshiba-aggressively-pushes-pcie-gen4-nvme-ssds/ one of the big benefits is that backplanes work across different types of drives. Usually, the storage guys are a bit behind the platform guys. Ice Lake Xeons in 2020 is when all of the current systems get re-designed.
4k Random Read IO performance numbers on 24 SAS SSD drives for above three
permormance modes. Performance data is from Intel Skylake and HGST SS300
(drive model SDLL1DLR400GCCA1).

The new interesting features are pcie 4.0, u.3 and for the raid controllers ddr4 2666MHz supportBroadcom 95xx cards are PCIe 4.0 and have been available for some time now.
if 6w is true that’s a nice saving for sure.Has anyone actually got their hands on one of the 9500 HBAs yet?
I saw that the 9500-8i was specced to use an anaemic 6W rather than the 10-15W I'm used to for my other 8i's and I wondered if anyone could verify. That combined with the single-port x8 SFF-8654 would make it a good fit for the sort of compact NAS box that I do a fair few of.
I think the only surprise I have here is that broadcom didn't try and ruin all of this much sooner...!You are absolutely right. Broadcom is seemingly going out of their way to stop this crossflashing business we so much like :.)
Firstly, thanks for the read. The cable situation does indeed seem to be even more bizarre than my preliminary research had suggested; luckily I'd be well served for my current desires by the regular 05-60003-00 8654 -> 2*8643 SAS/SATA breakout but glad to see an 8654 -> 8*8784 is technically possible.Ok my friends, here is my tech blog where I did a long write-up of all that I know and found out. Will make a direct thread post about it as well.
