More to the point, doesn't it also use 4xPCIe/NVMe?

Yea I think the 900 series is NVMe only while the 800 series is their SATA drives.

When you add the RD-400 to the OP, I would definitely make a note that it runs REALLY hot if used in a M.2 slot.. I experienced this on 2 different mobos and the previous owner had the same issue. The thermal pad on the included PCI Ex. adapter is really needed IMHO. Any sustained activity of more than 10 seconds or so without the thermal pad setup on the adapter will see it hitting temps in excess of 75 C. With the pad/adapter it never exceeded 55 in my tests. It may possibly be designed for that, but I'm not comfortable with it.

Found something interesting from Microsoft about using NVDIMM-N: https://channel9.msdn.com/events/Build/2016/P470 It's a bit old (back from April), but I don't believe I saw discussion about it.

Potato Salad posted:You should see the monstrosities on the DC enterprise cards. They get pretty flippin warm too even with the giant HS and expect something like 200LFM airflow going over them constantly. Most enterprise NVMe drives I've seen are in the 15-25W power consumption range which is quite a bit more than SAS/SATA (more like 8-10W). I should get a screenshot of the system I have with 10 NVRAM x8 drives running IOMeter over a x16 link via a switch, throughput hitting 14GB/sec. ~zoom~

What are y'all using to perform maintenance / imaging on m.2 NVMe drives? You'd have to have some kind of USB 3.1 device to actually use a four-lane NVMe device at full speed, but if all you're doing is maintenance / troubleshooting, 3.0 ought to be fine...

This one says it supports PCIe m.2 drives and is usb 3.1: https://www.amazon.ca/USB3-1-Adapter-Converter-External-Enclosure/dp/B00W76CTAY I've never heard of the brand, not sure if it's any good or not. It's also an enclosure so if you're doing a bunch of drives in a row it's not exactly the best option. However the only thing I could find by a brand I'm familiar with (which was StarTech) specifically said SATA only.

It does NOT support PCI-E based B key & any M key SSD. It's far too cheap to be anything but a USB to SATA converter, tbh. USB to pcie is not currently high enough volume for the whole thing to sell for $20. In general I kinda wonder how useful an enclosure which bridges NVME to USB mass storage class will be. It should be able to copy data fine, but it's probably safe to assume that any out of band commands like NVME SMART are going to be even less well supported than the SATA equivalents are on random USB SATA bridges. (Which is not very well supported at all.)

An external NVMe adapter would have to be one of those Thunderbolt or USB type C PCIe bridges and those are still in the "expensive and buggy" phase.

Not an 850 EVO, but a similar comparison. There's a stark bottleneck in sequential read/write: ...but you'll still get a huge improvement in random read/write over a HDD: In particular, I believe 4K random reads are the most important metric for general Windows application performance, and that's where the 3 GB/s limits you the least. Besides, you're presumably going to upgrade your 5 year old computer before you replace the SSD anyway, so you might as well pick up an 850 EVO.

Never buy based on the fact that your computer can't take advantage of the speed boost *now*. Sooner or later you'll end up with a laptop you can drop the SSD into or a new desktop. The standard SATA interface isn't going anywhere anytime soon.

I was going to ask the exact same thing, so thank you HMS Boromir. My hard drive is old and slow so definitely needs replacing as a priority, but if I can put off replacing the motherboard for a while that'd be great because I think I'll have to replace the CPU at the same time for compatibility. But my current CPU is perfectly fine so I'd rather put that off. Also, the release of these new Samsung 9XX SSDs doesn't change the 850 Evo being the go to for the average consumer right?

I am also guessing even with the throttling, the SSD will still be faster than my current HHD? If that is the case, then I may as well take the plunge.

Even with small legacy bandwidth restriction, the SSD eliminates seek time and rotational latency. Each storage operation request is fulfilled faster. Yes.

# ? Sep 25, 2016 01:15 |

And yeah, so far there are only NVMe 960 EVO and PROs...unless I missed something. If you're on SATA, stick to the SATA consumer list (and buy an 850 evo).

Unlucky7 posted:I am also guessing even with the throttling, the SSD will still be faster than my current HHD? SATA 3 will provide like 550MB/s maximum speed on an SSD, SATA 2 is going to be like 260 MB/s. I believe the only hard drives that can do anywhere close to 200 MB/s are going to be of a large capacity that will cost a lot of money. $300 will get you a WD Black 6TB that can do 220+ MB/s sequential, but it has <1 MB/s random 4k speeds. For $300 you can get an 850 Evo 1TB that will do 480 MB/s sequential and ~37/112 Read/Write MB/s 4k random.

I noticed that there were PCI Express cards that could provide Sata 3 slots. Is it not a bad idea to take advantage of that?

I've used several brands of Sata III add-in card, (Marvell, Jmicron, Asmedia) and none of them run anywhere near as quickly as a native Intel Sata III port. Some of them are buggy, too. Better to use the chipset's native ports, even if they're slower on paper. I use a cheapie BX100 drive in my media box that's only SATA II, and it's amazingly quicker than a spinning HD, even slightly bottlenecked.

The thing is that the random 4k performance is by far the most important metric and as you can see in the charts posted earlier a SSD will be 40-100 times faster in that type of work so yeah, even with the bottleneck a SSD will be vastly faster than any HDD.

HMS Boromir posted:So how has the 600p been shaking out? Reviews seem sparse and nobody's talking about it. Did anyone here buy one? I have one on a test setup at my work, it is no 950 (or one of the enterprise drive) but it is decent. I can run a benchmark on it if there is interest. Can't recall the numbers off the top of my head but they were the lowest of any gen3 nvme device I've tested, unsurprisingly.

I have had success booting off an Asmedia one in a 2008 Mac Pro, if you do use such a card, make sure it has two lanes of PCIe 2.0. The exact card I am using is this: https://eshop.macsales.com/item/OWC/SSDACL6G.S/ Many PCIe AHCI controllers I have seen have multiple SATA ports on a PCIe 1x card, this cannot supply enough bandwidth for even one SATA 3 device. With one drive, it seems to limit the read speed to a bit over 400MB/s, I have not tried with multiple drives at once. Avoid Marvel AHCI controllers, they don't work correctly with NCQ at SATA 3 speeds, at least in Linux. Turning NCQ off may fix this, but why would you deliberately use a buggy AHCI controller?

Finally got an 850 EVO. Once I got everything set up and turned on AHCI, starting up windows now works like a dream. Can't determine game speed loadup though: Most of my (Steam) games are off on a partition on my HDD, and the one game I had that was on my main disk partition (Witcher 3) stopped working after I copied it over to the SSD, and hasn't been working even though I redownloaded it. I am using GOG Galaxy though, and I am suspecting it is just that program being a piece of poo poo. I will get a copy of the game from GOG itself sometime today. I can say that WoW felt a bit snappier loading though. I know everyone says to ignore the OS optimizations in Magician, but what is this RAPID mode thing? I can't use it since I am on Windows 10, and apparently they do not offer support for it, yet. Is it actually useful? EDIT: Moved my Overwatch install to the SSD. Before, when I start up the game, maps take a while to load, and even when they did, character models are not loaded in yet. Now I load up before everyone else.
