New ssd Pcie vs Sata ll for old system and upgrade for new help!

[Floplox]

Right so I wanna buy a new ssd thats better than my hdd (7200rpm sata ll) Not only to feel a bit of boost now, but also to be carried over to my new system for full speeds with no bottleneck which I plan to build soonish..

First I thought I'd get an 850 evo, but I'll be stuck with the sata, then I was thinking M.2 950, but my old mobo doesn't support M.2 ha ha so it will jsut lay around. So now I wanna know if this makes sense. To buy a pcie ssd instead of the 850 evo put it into my Pcie 2.0 x 16. Which will still be improvement from my HDD, and when I bring it over to the new system with Pcie 3.0 it wouldn't interfere with a sli config etc. Maybe intel 750? pcie 3.0 x4 NVMe (will Nvme even work on my old crap, possible to run AHCI?)

Old system: BIOS version says 1302 if that matters for NVMe (running Win10)
Cpu Q6700 (lol)
Mobo: Maximus Extreme
Info from asus website
3 x PCIe x16 support dual PCIe2.0 x16 or 1x PCIe2.0 x16, dual x8 speed
2 x PCIe x1 , PCIex1_1 (black) is compatible with audio slot
2 x PCI 2.2

New system (plan to build)
Cpu i7 6700K
Maximus vlll Hero
2 x PCIe 3.0/2.0 x16 (x16 or dual x8, +gray)
1 x PCIe 3.0/2.0 x16 (x4 mode, +black)
3 x PCIe 3.0/2.0 x1
(No Sli at the beginning, but I wanna be able to upgrade to Sli whenever without problems for the ssd or gpu's)

I'm very confused with the compability and speeds of the various options.
If the Pcie option (Intel 750 etc. NVMe) Is even an option for my old system, will it be a lot faster than the 850 evo That I prob would have to resort to if it's indeed not an option.
I guess the speeds will be similar in the old system, but in the new maybe I will be glad I went Pcie over sata?
I just wanna "Futureproof" a bit and not buy the 850 and then when new rig is done buy a 950 etc,

Thanks in advance for all help on this matter, and feel free to ask for more info about old/new rig if thats needed.

I'd buy that 850 EVO. Those are really great SSD, for a decent price. They're over 10 times faster than your 7200RPM HDD, and aren't as pricy as a PCIe one. That "bottleneck" you're talking about isn't really one, SATA will still be a thing for the coming years, you only need something faster than that if you have to do large file transfers every single day. For gaming, you will barely see any speed improvements.

The price isn't really the issue as much, I know pretty much everything will make my HDD eat dirt. Well I'd imagine Pcie is the way forward as sata pretty much is at it limits.
I've read people see a couple of seconds reduction in load times Pcie vs sata. So I definitely fancy that. If thats true or not I'm not sure as I haven't tested it.
I'd assume the Pcie way is the more "futureproof" solution if it works on my old system as well as do more than crunch benchmarks compared to the 850 on the new rig.

 

[Mr Hat]

It's your choice 😉. Those intel PCIe SSDs look pretty nice

 

[Floplox]

Yea they do, just not sure if they will work in my old rig though :b

Hoping for some clearance about that from you guys great minds!

I read it uses PCIe 3.0 4x, but PCIe is backwards compatible, right? It might not give you the full speed on that old PC, but when you put in in your new PC, you'll discover the true power of this beast. I'm talking about those Intel ones, forgot to mention that

Yea I got 1 slot used 2.0 x16 - Then if I put it in the second slot it will be dual 2.0 x8 right? but then again only 2.0 x4 cause thats what the ssd says it runs at I guess. How are the numbers 2.0 x4 compared to sata ll with the 850? will both GPU and ssd then run at dual 2.0 x4 affect GPU?
I guess it's backwards compatible, at least on the mobo but the ssd is 3.0 but not 100% as why I post. As well as the NVMe will that even work with my old mobo / bios, or can it simply not boot/find the drive. Is it possible to run it ACHI, will it affect speeds?

In the new rig I see I can run a sli config and got the 1 x PCIe 3.0/2.0 x16 (x4 mode, +black) left free. Which then will be great but the (x4 mode), is it optimized for that? what makes the "black" differ from the "Grey" They seem identical to me.

I'm really sorry, but your message is really chaotic, I cannot get what you're trying to say. Sorry again :/

Ha ha I'm sorry, I figured it world be a bit, thoughts to keyboard kinda thing. I'll try and clear it up if I can.
Though I do not fully comprehend all of this, so it might still be jibberish for all I know.

So In my old/current rig (pcie specs listed above) I run a gpu in the first slot. Now if I put the ssd in the next slot, it says above it will run dual x8 instead. Though the SSD is x4. Will that make both gpu and ssd run x4?
Or will it be x8 for gpu and x4 for ssd? Either way will it affect my gpu?
Next if above works, what will the numbers be with a 2.0 x4 ssd. 850 evo sata ll vs Intel 2.0 x4 etc.
If the intel 750 3.0 is even backwards compatible at all, dunno if it needs that Gen 3 slot.
Then the probably biggest concern of mine is wether I can even use the intel 750 as a boot drive, due to the NVMe.
Intel said that only x99 and 79 systems (I belive, don't hang me up on this) are able to use it as a boot drive. However other people with some tweaking in bios had made it work.
Can this be done for my mobo? I suspect not, just wanted to make sure wether it could be done or not.

The second bit was just some confussion I had about the pcie slots on the new rig with the vlll Hero (See main post) as I understand it, I can run sli config with one pcie slot left free (black one) and use the black for the ssd.
"1 x PCIe 3.0/2.0 x16 (x4 mode, +black)" I just dont understand the "x4 mode" is it optimized for this`? As I see them the black and grey are identical?

I hope it cleared it up a little

 

[Mr Hat]

Yea you did, thanks

I think the board will run or GPU at 16x, SSD at 4x, or GPU at 8x, SSD at 4x. As far as I know, no issues at all.

2.0 4x is half as fast as 3.0 4x. You'll not get the full potential out of your device.

For the whole NVMe thing, I think it's the best to create a new thread, you'll get way more answers, since I don't know what to do about that one.

No idea what that black thing is, as long as it is PCIe 3.0 4x on your new mobo, it should work fine, black *or* grey

 

[Floplox]

Right well thats good, one check on that then ha ha.

I know 2.0 is slower than 3.0. The comparison was 850 evo vs intel 750. So a Sata Gen 2 VS Pcie gen 2.0 x4

Yea you might be right, I'll leave this open for a bit if others might have something to add on Nvme or the speeds above.

There are 2 grey and 1 black pcie slot on the motherboard. I guess the grey are "meant" for gpu's in sli. and the black is just the same but an extra expansion slot? Since both grey and black run at x16. Just messed with my head Asus put the x4 in parenthesis.

 

[Mr Hat]

Yea, I think the mobo prefers to have SLI there, in the grey PCIe's, probably like some mobos have RAM spot preferences....

I hope I helped you out a bit, and that other people can answer you other questionss, good luck
