Why the fuck z97 mobos manufacturers impose such a retarded limitation in the M.2 socket? Realistically, how hard it could have been for the M.2 socket to use x4 PCI-e 2.0 lanes instead of x2 or make it share lanes with the 16x PCI-e 3.0 slot? (and at the same time making it compatible with new 4x PCI-e 3.0 NVMe M.2s, two birds one stone)
There is literally a 1% performance hit when running a GPU on 8x PCI-e 3.0 lanes instead of 16x.
I just can't find any reasons to justify such a stupid decision, specially when the z97 has plenty of lanes that could have been used by the M.2 socket.
This so much, damn.
I searched the manual and online resources to find out if any other internal component, wifi or bluetooth modules use the 6x remaining pci-e 2.0 lanes. Nothing. By the way things are, it seems those 2.0 lanes just sit in the mobo doing jack shit.
How extra retarded you can get illiterate snowflake?

We are talking about the maximum speed the bandwidth cap allows, holy kek /g/ really is full of idiots like you pretending to know their shit
Good idea, sadly the m.2 slot is in the rear of the mobo
It because most Z97 boards use the other PCIe 2.0 lanes for other peripherals (NIC, SATA controller etc).
It doesn't matter anyway because M.2 Express is bloody overkill for non-professional-tier workloads.
SATA-600 SSD devices are more than enough for majority of the users out there.
Protip: NVe is the spiritual successor to SCSI.
Originally I thought this and searched in vain the manual and e-resources to find out what peripherals use the remaining x6 Pci-e 2.0 .
Could you share a link detailing what you just posted? If this truly is the case, the decision seems less retarded although the ideal choice was making the m.2 socket share bandwidth with the 16x Pci-e 3.0 slot.
The only M.2 SSD that uses 2x Pci-e 2.0 is the m6e from a pleb tier brand "plextor"
A PCIe SSD and a M.2 SSD that uses PCIe lanes are two different things.
Also if you have the free socket and the money, why not? Unlike Sata III, PCIe SSDs (and M.2 PCIe SSDs) are not limited to 600MB/s and the one in OP's picture has triple the speed of a 2.5" Sata III SSD.
Pic. related is a PCIe SSD compared to two M.2 SSDs that uses PCIe lanes.
Forgot to mention M.2 SSDs that use Sata III also exist.
>overpriced chipset directed to goodgoy "enthusiast" sheepie
>used in overpriced mobos employing overpriced cpus with useless extra cores
I have the same 'issue'.
I have a Samsung SM951 M.2, which can run upto 4x.
But my Asus Hero VII Z97 motherboard only supports up to 2x.
I still get 750MB/s read and write though, which is enough.
m.2 is shit and should stay in laptop/tablets only
workstations mobos should use u.2 ports instead, which let you use 2.5" drives that don't get thermally throttles at the earliest opportunity.
yes, m.2 -> u.2 adapter exist, but they're not very mechanically robust and look like shit.
For that mobo a wiser choice was the Kingston M.2 in OP since the 951 is OEM and has no official support from Samsung, also using a M.2 4x PCIe 3.0 SSD (4GB/s max) in a M.2 2x PCIe 2.0 socket (1GB/s max) is a massive bottleneck compared to a M.2 4x PCIe 2.0 SSD (2GB/s max) used in a 2x PCIe 2.0 socket, 1/4 vs 1/2 speed.
Still 750MB is blazing fast and I am sure it covers most of your needs.
>m.2 is shit
>workstations mobos should use u.2 ports instead
You got it backwards
Not a single u.2 peripheral under a recognized quality brand is being produced and M.2 is becoming a desktop standard. The fact that z170 mobos bring support for x4 Pci express gen3 only cements this.
U.2 is shit and went through a quick, painless death. RIP U.2 nobody is gonna miss you.
entire enterprise sector is moving from PCIe card to u.2 for higher capacities.
Intel's DC P3xxx series and high-end consumer 750 series are both offered in u.2 and not m.2 for obvious reasons.
m.2 cards can't dissipate more than a few watts of heat, and high-end SSDs can easily sustain 20-25W (at 100s of kIOPS) if adequately cooled.
>Samsung SM951 M.2 on a M.2 PCI-E Generation 2 x2
Sweet jesus you are a special kind of retard
The prime example of a consumer whore who buys the newest and shiniest shit promoted by marketeers without doing any kind of research beforehand
>I just can't find any reasons to justify such a stupid decision
Most manufacturers did an horrible job labeling m.2 slots, using explanations that only generated confusion, approaching marketing deception territory. Take Asus for example: to this day I have yet to see a M.2 SSD using PCI Express x2 (Gen 2.0??) reaching speeds near 10Gb/s. Isn't 8Gb/s the speed limit of PCI Express x2 (2.0)? Where does the extra 2Gb/s come from?
Why are you even worried about a Z97? That's old fucking shit bro. We are on Z170. Get your shit right and stop bitching about your Gen1 tech. Also, your faggot porn will save just fine on that old shit you've got.
Also note that there is no single M.2 PCI Express x2 Gen 2.0 SSD that reaches the full 8Gb/s or 1GB/s. The 512 GB Plextor m6e (priciest model) only reaches up to 770 MB/s read and 625 MB/s write, also it is the only M.2 brand that uses PCI Express x2 Gen 2.0 as >>52971675 said. IMHO not worth it.
Yeah, I am sure the millions of Z97 mobos that got sold completely dropped of earth after the arrival of Z170, and that none of the z97 are considering upgrading to a M.2 SSD.
It's thanks to enabling morons like you that companies fuck us in the ass whenever they want. At least the thread creates awareness about the issue for potential buyers so they don't waste their money.
>>52972519 Intel's 750 has u.2. It will become a standard. u2 just has a tiny board to plug into m.2 slots.
>become a standard
A standard meme of course
Here, this should explain things a bit more
reading is for idiots too dumb to win at video games.
Isn't it time to finally implement 10GBit Ethernet?
I just recently started wondering why I'm not using a NAS yet and why NASs are so slow since fucking 15 years. Because that's like the timespan we've got Giggerbit nearly everywhere.
Why am I the only one wanting a NAS that's equally fast as S-ATA?
Or is S-ATA already able to be maxed out via Gigabit Ethernet?
Why? Because these new pcie x4 cards are quite new. There was not anything like it when z97 came along. The blazing fast m.2 drives came out right at the end of z97. x99 has a few x4 m.2 slots, however.
I always thought NAS was slow because of the HDD's. I wouldn't mind really if my NAS had a 3.1 or 3.0 usb that's alot of speed potential, but I would imagine it wouldn't be any faster than the storage medium.
The graph shows the Pci Express lanes from the chipset and CPU operate independently from each other, as already stated. Also it shows 8 x PCI Express 2.0 lanes coming from chipset.
Take this mobo for example: its the Asus z97 mini-itx. It comes with integrated wifi and bluetooth that nowhere in the manual or official site list as using PCI Express lanes. We already know the M.2 uses 2 x PCI Express 2.0 lanes, so my question is: What peripherals or internals use the remaining 6 x?
I see.. so the faster tech is pretty new. Makes a lot of sense, also puts the whole issue into perspective.
>he didn't do research
I specifically bought a motherboard with m.2 x4 support.
Why didn't you?
I wasn't going for a full ATX mobo at the time anon. The only mobo that supported m.2 x4 in my form factor was the ASUS MAXIMUS VII IMPACT and it trades too many features for the m.2 support.
This is one of the things that prevented me from buying a mITX build when I built my current machine.
It was disappointing, but there's no way I was going to invest in skyshit.
I have given serious thought to designing my own case and having a fab shop make it. Why aren't there any "Small" ATX cases.
skyshit has more lanes available to keep shit like this from occurring. Its one of the many upgrades from the limited z97. But keep on memeing it up.
Also I guess to add to that, I just got my m.2 drive just the other day. Turns out it's AHCI though.
Seems to me like NVME vs AHCI makes a bigger difference than x2 vs x4. Wrong? Probably going to keep this until they fix the heat issue though.
>Seems to me like NVME vs AHCI makes a bigger difference than x2 vs x4. Wrong?
Yes and no.
In theory, and in the future, NVMe is much faster.
Especially with many small files (the stated speeds are best case scenario, they drop dramatically on random read/writes).
But software needs to be specifically written to take full advantage.
And hardly anything is yet.
The z97I-Plus reaches slightly higher stable overclocks overall, also at the moment of purchase the price difference was 80 bucks and I needed the DVI port.
You have an excellent mobo anon, if I could go back in time no doubt I would buy the VII Impact.
Yeah, I guess with reduced size come reduced features. But I could not resist the portability the Mini-Itx cases offered
>Why aren't there any "Small" ATX cases.
Have you looked at micro-atx? Maybe there is a mobo that could fit your needs.
If only mobo manufacturers introduced mainstream support for the Mini-DTX format. What are they waiting for? It would be a dream come true.
>Mini-itx sized mobo with TWO, yes, TWO 16x PCI Express 3 for a small form factor sli-build or double PCI Express peripheral
I would pay premium price for this.
Good to know. Thanks for explaining
>z97I-Plus reaches slightly higher stable overclocks overall
Really? That makes no sense to me as the Impact is an RoG board advertised for it. I thought I remember looking up it has better chokes, mosfets, etc
The irony is OC is the reason I got it over the Plus and the Z87. I think it's overpriced for what it is, still not a bad board though. Only reason why I bought a m.2. drive for it is so I can justify the price difference.
>falling for the M.2 meme
It's for laptops and tablets, not for desktops.
Desktop motherboards only carry them in case you want to re-use your old laptop drives.
>Mini-itx with two PCIe3 slots
Fuck me I would pay mad cash for a mobo like that. Why the fags at Asus, Asrock or Gigabyte haven't produced one of this yet?
We need to contact one of them or at least make a petition in change dot org maybe if it gathers enough firms something could happen
What is there to explain?
AHCI was never designed for SSD's.
Of course it was going to cause a bottleneck.
Currently the fastest SSD on the market uses the M.2 slot (950 pro). M.2 SSDs that use PCI-e aren't bottlenecked by Sata III speed.
Also if your board only supports 4 sata ports the extra storage could be useful, otherwise its just for fags to showoff.
If you aren't doing crazy video editing and heavy productivity tasks, even a Sata III M.2 suffices most needs.
He means instead of a normal PCIe card.
Sure, like >>52975093 pointed out on mITX board you might not have a free PCIe slot.
But other than that there is no reason to use pick M.2 over a normal PCIe card.
The real pros are showcased when using a mini itx board, where space is very limited.
As >>52975533 said: less bulk and cables, more space for a decent-high-enthusiast graphics card. Using M.2 in full atx where Sata III have comparable speed is questionable... at best.
TL;DR extra speed less space used
It's just stupid to not get 1TB of already fast storage, vs 500gbs of slightly faster storage, unless you're of the 1% of the 1% that needs storage that fast for your workload
I don't understand why anyone would want a 1TB SSD. I have literally only 130GB used on my SSD. What are you going to do with 1TB? Watch chinese cartoons? Kek HDDs are pretty good at sequential reading. I'm getting 150MB/s from my 3TB HDD.
My reaction image folder takes 9 minutes to fully load in a HDD.
And is 290GB big.
I want to stuff load quickly as possible.
I could organize it but why do it when i can just pay for faster loading times?
do what i did and get the Asrock z97 extreme6/9
dual m.2 ultra which are uncapped.
but just a FYI. the performance benefin compared to sata6 is no existant in day to day usage, even game load time isnt increased.
i traded my intel 750 pcie for a 850pro sata6 disk, which btw was faster in normal use.
