Seagate has launched three new 12 TB helium-filled hard disk drives containing eight perpendicular magnetic recording (PMR) platters:

These are not the first 12TB drives in the market, as enterprise versions from both Seagate and Western Digital have been around for some time. However, Seagate is the first vendor to bring down the prices and ship 12TB drives in the consumer market.

From a hardware viewpoint, the three drives are similar to the Seagate Enterprise Capacity v7 drives launched in March 2017. All of them features eight PMR platters with a 923 Gb/in2 areal density in a sealed enclosure filled with helium. That said, the Barracuda Pro Compute, meant for desktop use, doesn't come with rotational vibration (RV) sensors or dual-plane motor balancing hardware. The RV sensors and the dual-plane balance / AgileArray features enable reliable performance in multi-drive enclosures. The other important differentiation aspects include firmware features, warranty / workload ratings, and value-added services like the Seagate Rescue Data Recovery.

Two of the drives come with 5 year warranties.

    10G switches might be expensive, but 10G ports are cheap.

    A colleague pointed out the intel D class that has 2 of them....

    I agree you can get Supermicro E200 with two 10G ports for just a couple hundred bucks, plus all the other server stuff. My basement kinda resembles that in fact. And I know you can buy full size desktop cards with immense heatsinks for like $50.

    The cost seems to be the bus. The biggest PCI-Express MB I can think of had 8 slots. Speed doesn't matter because even the oldest PCI-E had way more bandwidth than a card can generate. I "need" 12 ports aka 12 cards aka 12 slots on a motherboard running linux and some bridge software to emulate a switch.

    Home labs are kinda like ham radio where there's a zillion levels and people laugh at the layers beneath them and think one level up is insane and where they are is just right.

    Given the above line, I've been thinking about skipping 10G and being the most alpha-tech I know by installing used 40G infiniband gear from ebay. No one I know IRL has infiniband in their basement so I guess it would be bragging rights. Even if half of what I buy is DOA it would still be cheaper than buying into 10G. I mean $600 gets me 36 managed (admittedly, used) ports of 40G QDR infiniband. Its just mindblowing that even if I have to buy two because one is broken, its still cheaper than the new 16 port 10G switch I was looking into.

    Hardware compatibility is likely the killer. My 10G ports came up with one line installation of a VIB and "just work" on vmware esx but I can only do pt-pt links I don't have a $1700 switch. On the other hand infiniband would be vastly cheaper and faster, but the headache of getting that stuff working, I donno.

    Also my cute little server cases have risers that would hold an infiniband card but I'd have to rip out some guts and go full on SAN / NAS whereas kinda the point of faster networking is better vsan. Still imagine FT-logging or vmotion running over 40G infiniband instead of 1G ethernet.... I think there's CPU sockets that don't have 40G bandwidth, crazy stuff. FT performance is probably pretty good when your network is faster than your CPU socket LOL.

    Of course if I'm willing to put up with used equiment BS, I could get a used 10G 16 port switch for less than $1700 new... Lots of decisions to make...

      My FPGA eval board can easily run 100G as 25G x 4.
      My biggest problem is I don't have enough HD cameras in my house to justify that much bandwidth. Maybe I should register for AirBnB

        justify that much bandwidth

        Get into virtualization and nothing is too much. FT essentially uses the network to keep two images sync'd over the network so if one host fails the other takes over basically instantly. vmotion moves a snapshot of the entire memory and processor state of an image from one hardware machine to another ideally instantly in practice it would be nice to reduce the slowdown/stop from dozen seconds to one or so. My media server talks to its SAN over ethernet, in theory 100meg FE is fast enough to stream, but tasks like indexing benefit from "network is faster than most local storage" type speeds.
