2+ GBps storage that doesn't require its own desk space and power supply and RAID card! Exciting times for us in film and video. Now all we need is more space and a price drop! ~4TB would be enough for 2k mastering. 16TB for 4k.

16TB SSD is coming from Samsung next year:

Can't wait! Time for dotHill-like performance to trickle down to affordable range. Last two things then are affordable 10-bit monitors and gfx cards with 10-bit output and alternative to infiniband.

Whats wrong with Infiniband? Cost is typically less than dealing with Ethernet NICs that can do RoCE.

Intel is also moving ahead with their Infiniband implementation as the "supercomputing" cross-chassis bus (QPI is a clone of Hypertransport, but Intel decided not to use it for supercomputing bus fabrics like AMD does with their externally switched Hypertransport implementation), so future Xeons and future Phis will have on-die True Scale controllers.

Nothing's wrong with infiniband, of course! Except for prices compared to average SoHo network infrastructure. Video mastering and editing networks usually aren't large. You need a fast SAN with fast network and up you go. Everything around it is so expensive though. In recent years there have been a massive price drop in fast storage, fast graphics cards and now we wait for cheap fast networks and 10-bit through and through.

[DiabloD3]

Exactly how fast are we talking? Dual 10gbit nics are now often for $150 + cost of optical modules or DACs.

We're talking mastering here. For editing it doesn't matter since it can and is done in proxies. Depending on the bit-depth and fps we're talking anywhere between ~127 MBps to ~253MBps (1+ - 2+ Gbps) per workstation. Usually there are several and a one heavy NAS or several smaller ones. That's for 2K (and HD - but then it's a bit smaller bandwidth). For 4K it's four times that.

Cabling I'd suspect. The copper cables are thick, the fiber QSFPs are expensive.

[DiabloD3]

The fiber QSFP modules are the same ones used for Ethernet, ergo, 40gbit Ethernet and 56gbit Infiniband are going to have the same issue with QSFP modules being expensive.

There are companies out there shipping NVMe SSD's in much larger capacities. Novachips is one that we've started testing with, and so far the performance is great.

Their 4TB models are around $1/gb mark; the higher capacity models are much lower $/gb. So far we've only tested the 2.5" models and haven't had a chance to play with the 8/16TB PCIe add-in cards.

GB/Gb damn

Your figure was correct per my reading of the specs.
