Doing a short Lunch and Learn presentation on NVMe over fabrics tomorrow and set up a demo system, it's pretty neat Initiator: Raptor POWER9 with Mellanox ConnectX 5 RDMA (gen4) capable 2x100GbE NIC Target: Raptor POWER9 with Mellanox ConnectX 5, PCIe gen4 fanout switch to a bunch of x8 gen3 NVRAM cards Too easy to saturate a 100GbE link though, I have never done bonded links otherwise I would try that out..

ilkhan posted:My current setup is a WD Black 250 (windows boot and whatever games I'm currently playing drive), samsung 850 pro 256 (dedicated linux drive), and a 1TB spinner (dedicated storage drive and rest of the steam library). When I build my Ryzen 3700 rig I want to go all m.2, trading the 850 pro and the spinner for a 1TB m.2 as a windows drive and using the black for the linux drive. Besides the inland premium, what should I be looking at? Or is the Inland just that good? A 2TB option wouldn't be horrible either. The Inland Premium isn't that special, it's just significantly cheaper than any other quality TLC NVMe drive. Other drives that provide good value at somewhat similar prices are the HP EX920/EX950, ADATA SX8200 Pro, and any of the Phison E12 drives (Sabrent Rocker, Corsair MP510, etc.). Edit: I should probably add that the general opinion of almost everyone in this thread is that we've reached a point where you're not going to notice the difference between the speed of TLC NVMe drives like the ones listed above. You might see it in benchmarks, but in practice just buy whatever the best value is from a trusted brand and save your money for other spec bumps. With the exception of QLC drives like the Intel 660P there seems to be a price premium for 2TB NVMe drives at this point. IE, you pay more than double the cost of a 1TB to get a 2TB.

I was looking up prices of 2TB drives in response to the previous post, and I found a poo poo-hot deal on a 2TB E12 drive: https://www.amazon.com/Silicon-Power-Gen3x4-000MB-SU002TBP34A80M28AB/dp/B07QR8LD7Y/ ($229.99 as of the time I'm posting this) Only slightly more than double the price of 1TB E12, cheapest I've ever seen for any TLC 2TB drive. (That being said, there are a lot of them in the upper-mid-200s, whereas the last time I checked it was over $300 starting.) Kairos fucked around with this message at 11:26 on Jun 27, 2019 |

Maybe if you're doing some kind of fancy MPIO iSCSI config you'd be able to aggregate traffic over both links but that's more work beyond the LACP setup.

I've wanted to do that for my daughter since her S is only 500gb It's not designed to be hot-swappable, but it isn't all that hard if you know how to handle a screwdriver and electronics. You do need a SATA USB adapter (or an empty UBS drive enclosure) to partition the drive from a PC as well as a thumb drive to reinstall the Xbox OS from. To partition the drive, the script by Xfix comes in handy (xboxonehdd-master): https://drive.google.com/drive/folders/0B1dVghgrDEb7d0FieWdBeVh5VWM Just select the option to partition without a preexisting drive, reinstall the drive, start the Xbox and do a full reset, then reinstall the Xbox OS from the thumb drive (downloadable from Microsoft's website).

I wonder how this will effect the price of SSDs: https://www.anandtech.com/show/14596/toshiba-western-digital-nand-production-partially-halted-by-power-outage quote:Considering that the Yokkaichi Operations produces at least 1/3 of the global NAND flash output (let’s assume that dollar share more or less corresponds to bit share) and half of its production for the quarter was lost because of the incident, this means that the industry will miss approximately 1/6 (or 16.5%) of the global NAND supply in Q3. Whether or not this will create a deficit on the market that will cause significant price hikes depends on multiple factors and is something that remains to be seen.

USB NVMe enclosures are pretty expensive and I would expect that a QLC drive would run into bit rot issues sooner than a TLC drive. USB NVMe enclosures are $50 or so. 1 year retention is fine. Anything needing longer storage time is on a cloud host, so this is purely for time machine level backups

One additional tidbit: The boot animation will be missing after a fresh partitioning until the next system update happens. If you don't want to wait and want it back immediately you need to download the bootanim-File for your system from that Google Drive, power down your Xbox & disconnect the drive, connect it to your PC again and copy it inside the System Update partition's A and B folders (bootanim.dat in both). After that, should be smooth sailing: I've had a modded drive in my Xbox for more than a year now and never experienced any problems, works just like stock (but way faster). And this is where you can download the Xbox OS ("I need to update my console offline"): https://support.xbox.com/en-US/xbox-one/console/system-updates-solution Lambert fucked around with this message at 07:58 on Jun 29, 2019 |

Most factories use way to much power to have generator backups to be viable and you can't pause the process in a low power mode. The batteries were probably more there so it would fail safe rather than somehow scramble to find another power source or connection which wouldn't matter if it was a general power outage.

Back when some important components in our main cabin at work blew and Schneider Electric quoted like 14 weeks for the part to arrive, we had a several megawatts in diesel generators on site. We still had a backup supply line feeding into the plant. But a few departments with higher requirements had to still schedule the capacity between each other.

Because NAND cells need to be refreshed eventually. The more bits you're storing in a cell, the sooner it has to happen. Four bits means you need to be able to discern between 16 charge levels.

You would not carry your backup drive around with you! You would, ideally, have a backup drive at home and then a remote backup so you could, gasp, restore from the remote backup if necessary! Imagine not having to even carry around an expensive "gumstick" in an overpriced enclosure!  And no, an HDD will not "die if you look at it funny." As long as the drive isn't flawed and fails prematurely, you'll most likely get years of reliable use out of it as long as you don't loving drop it or something.

How do the Adata XPG drives hold up against drives like the Inland Pro (Premium? I forget which is better) or the HP 920? A lot of sales have pushed those drives to $100/1TB and I was wondering if $20 for the XPG would be worth it or if the difference is even noticable. Added question: I'm upgrading to a Ryzen system and I wanted to have two NVMe drives-a 1TB boot and then a 2TB storage (Intel 660p). The MSI Carbon mobo has two m.2 slots but I was thinking I may go with the Tomahawk and use a PCI to m2 adapter, since I don't need other PCI slots (and they'd be disabled on the Carbon anyway). Is there a pitfall there I'm not seeing? Humerus fucked around with this message at 13:41 on Jul 1, 2019 |

A lot of sales have pushed those drives to $100/1TB and I was wondering if $20 for the XPG would be worth it or if the difference is even noticable. The ADATA 8200 Pro and HP EX950 are essentially the same drive. IIRC they perform slightly better on paper than the E12 drives like the Inland Premium, but you'll never notice in real life and probably not even in benchmarks. I'd save the money. I'm assuming you meant PCIe instead of the way old PCI standard? I'm not sure what advantage you'd get by freeing up a M.2 port you're not using anyway, but other than possibly not being able to boot off the drive using the adapter (motherboard dependent) I don't see any issue with that. Seamonster posted:Sabrent Rocket; JAPE12C (just another phison e12 controller) on sale: Interesting to see that MicroCenter and Sabrent, who both sell drives under their own names, are continuing to drop prices even after the announcement of the power outage last week.

Yeah PCIe, and on the Tomahawk board there's only one m2 slot (that would have a TLC drive in it), hence using a PCIe adapter for a storage drive. Mainly I want to get rid of extra cables in the case.
