It won't.Get this to consumer drives (and prices) ASAP! (Folks bottlenecked by storage speeds might pay $400 or even $500-$600 for a 1 TB drive that fast, but, most consumers are not going to pay the ridiculous $2k-$3k that some of the 'DataCenter'-intended cards go for...
This makes sense. Current 3D Xpoint requires lots of power to reach high bandwidth. It's probably the reason Intel's Optane SSDs are relatively low for sequential specs, so it doesn't use so much power.it has an'8 pin power' input? as in a PCI-e 8 pin like that typically connected to a GPU?
SSDs can only pull up to 25W from a PCIe slot. It needs that 8-pin to supplement anything draw more than that.it has an'8 pin power' input? as in a PCI-e 8 pin like that typically connected to a GPU?
Hard to imagine the 75 watts available from a PCI-e slot not being sufficient, but,..I guess we hope to know in 4 years when this hits desktop at a decent price point.
Don't hold your breath. Intel Optane SSDs are over $4/GB for datacenter (P4800X) and over $1/GB for consumer (905P). I would expect the higher-performing Micron drive to be even more expensive. It could be well over 5 years before you see a consumer version anything close to $0.50/GB.Get this to consumer drives (and prices) ASAP!

Well, it was a given that NVMe would come down, because the only real difference between that and SATA is the controller. Plus, M.2 drives avoid the added cost of a case. Yet, the fastest NAND-based NVMe drives will continue to command a premium, since they'll use lower-density NAND to get better performance.Similar prices to what SATA SSD's were originally.
This too will come down eventually.
Probably because the chips they used can only run up to a certain speed, and the controller can support only so many chips? Just a guess.The only thing I am wondering is why they stopped at 9 gigabytes per second?
Low-QD IOPS is actually where 3D XPoint is unparalleled.Looks good on paper but hardly matters for most users.....The problem is never with sequential read/write. Its nature of I/O.... Because most of our daily I/O consist of numerous small files at very low queue depths (hardly more than 5).
Apps that will benefit use I/O Completion Ports or other means of asynchronous I/O (Linux has its own flavor - Posix AIO is poorly designed and the Linux implementation is even worse).Another is windows itself. How I/O is performed. Windows reads file by file (serial form).... So transfer rate becomes very low when you have numerous small files. This needs to change before we can see big improvement.
Using conventional benchmarks, but has anyone ever managed to quantify "responsiveness" in a real-world benchmark?We have already seen performance with 905P....... In real life usage, performance boost over normal NVMe SSD is very small.
It's even worse in real-world load testing. Optane loads minimally faster.Using conventional benchmarks, but has anyone ever managed to quantify "responsiveness" in a real-world benchmark?
It has to be heat. If you look at the M.2 version of P4801X datacenter Optane drives, the lower capacity version lowers power but has significantly lower speeds too.The only thing I am wondering is why they stopped at 9 gigabytes per second?
Yes, it is full length, but a company rep at the event stated it could only pull 25W from the slot, that is why the additional connector was added in. "An Enterprise PCIe SSD(s) shall get all its power from the 12V pins" and the max power limit is 25W. It is part of Enterprise SSD spec. See page 37 here: http://www.ssdformfactor.org/docs/SSD_Form_Factor_Version1_a.pdfThat applies only to M.2 slots. The article is obviously concerning a full-sized x16 PCIe card, so it can get up to 75 W from that slot.
Thank you for the clarification. I did try to see what the limit was on the M.2 slot, but the info wasn't very easy to find. In the end, I saw another forum poster (on another site) claiming it was 25 W and concluded that's probably what you were talking about. However, perhaps they were actually confusing the spec you cited with M.2.Yes, it is full length, but a company rep at the event stated it could only pull 25W from the slot
A big selling point of NVMe is that you can create a large number of deep queues, specifically to get lots of transactions in flight and decouple I/O from different applications.Patrick Kennedy asked a good question in his newsletter: how does this AIC present itself to an operating system? e.g. can it be "bifurcated" like other "4x4" AICs? and, if so, would there be any performance advantage to doing so?
If the driver is so bone-headed as to be single-threaded, then they should just lean on MS to fix that. I doubt it, though.Theoretically, then, a "4x4" option may compute driver overhead faster than a default option that computes driver overhead in a single CPU core.
Please think about the whole sentence, not focus on a single word.Worse? What are you talking about? I don't know about this product, but the 905P is the most responsive NVMe drive you can buy!
