Will this SSD Work properly in my Motherboard

[GabrielFerrazTPU]

Hey guys, it's me again.

 

I'm using right now a X99 Gaming G1 Wifi motherboard with a 6950X overclock, and a Samsung EVO 860 1TB SSD, but i wanted to buy a M.2 SSD, i understand the use for these types of SSD, the loading times of games for example doesn't really change, but i still want it. I want the best performance.

The problem is this, my motherboard has an M.2 slot as you can see here: 

1. 1 x M.2 PCIe connector
   (Socket 3, M key, type 2260/2280 SATA & PCIe x2/x1 SSD support)

But according to it's manual the M.2 has a "top speed" of 10Gbit/s (a Byte is 8 bits so its about 1250MB/s top speed right?), as you can see here:

 

And the model that i was aiming for is the Samsung MZ-V6P2T0BW, an M2. 2280 2TB SSD with Max Sequential Read Up to 3500 MBps and Max Sequential Write Up to 2100 MBps. And by my calculation if you convert for exemplo theses 3500MB into Megabits its about 28Gbit/s(8x3500MB/s) right. So i migh bottleneck?

If i get this SSD it will bottleneck and i wont get the maximus speed of these SSD's?

Are you using this drive for boot?

Id just get a pcie to m.2 adapter and put it in a pcie slot. That way you can get the full speed as the ssd will work over the cpu pcie lanes instead of going over the chipset with pcie2 and only 2 lanes.

 

This adapter will work fine and is pretty cheap https://www.newegg.com/Product/Product.aspx?Item=9SIAC5C89G2624&Description=pcie to m.2&cm_re=pcie_to_m.2-_-15-124-167-_-Product

Yep that Samsung drive will be bottlenecked. I agree with @Electronics Wizardy that the best performance can be had by going with an add-in card as you can leverage PCIe 3.0 that way. Otherwise, get a cheaper NVMe drive, like a WD Black, Intel 600p/760p or similar.

[LukeSavenije]

yep, but you probebly don't even notice it in daily workloads, as the difference between sata and NVME is only about a second or two. if you really want full speed, the best suggestion is to do what @Electronics Wizardy said. Or just get a sata ssd...

Yes i'd be using this 2TB drive for boot and lefting my 1TB drive for backup, movies and games.

I though these adapters would only come with a few motherboard like thoses ROG ASUS models.

But let's say for an instance, that it doesn't work, what should i do, i would try updating the BIOS to see if works but lets say it didn't.

That was my fear about the bottleneck

Honestly i'd rather pay more for Samsung or even a Hyper X model than a WD entry level.

Thanks, and what about RAID 0? Do you think it's worth? 

PS: I know about the beneffits and de disadvantagens

The 10 Gb/s speed represents a PCIe 2.0 x2 connection. That uses 8b/10b encoding, so the theoretical usable bandwidth is only 8 Gb/s = 1 GB/s. Fast NVMe SSDs routinely break 2 GB/s in sequential transfers, so they definitely get bottlenecked by your slot.

 

However, transfer speeds are much lower for random access to smaller files, and those kinds of use are more common and more noticeable to the user. So the bottlenecking may not really affect the user experience much.

Problem with raid is your can't boot from it here(easily)

I editied my comment above with a link to a adapter. It Should be bootable, but otherwise boot from your 1tb and put games on the new 2tb pcie drive. The speed difference won't matter anyways. If you want the fastest possible get a optane drive.

Yeah i knew about that, and what about the latency. Does it have a great diference to an SSD SATA?

Its a bit better but your still limited by nand, but what are you doing that the latency matters? If you need super low latency get optane.

i wont spent any money buying a optane module, if i had a HD ok, thats an option if you dont want an SSD and want to spend money.

You mean because the RAID mode must be enable in the BIOS otherwise it wont be recognized?

It was just a curiosity, it doesn't matter to me.

Optane drives are just normal nvme ssds. You can use them like any other drive. You don't need to cache a hdd with them.

THe raid mode is your bios is for sata only. If you want to do raid of pcie drives, you need a newer board or software raid(not supported in windows for boot drives(easily)

for the value I would just get a single one on each channel. you can still get multiple ssd's, but you use them for different tasks. let's say a smaller one for your os and a bigger one for games for example.

They're basically cache memory...

I mentioned RAID as SATA, and also M.2 Raid would be bottleneck either even with a newer motherboard, because of the limitation of the M.2 slot itselft

Thanks but instead of having a lot of SSD's i'd rather have only 2, one for backup and one for OS with games in it.

Optane drives are nvme drives and will work like any otther drives. There aren't cache drives, all the caching is done in software. They have much lower latency and write endurance and are much faster for many uses than a nand ssd, probably way overkill here, but they would be faster.

 

How would the m.2 slot be a limit for nvme raid? You can use multiple slots and raid those slots together.

 

Really, get a sata ssd, fast enough and you won't notice the speed difference.

well, for backups I wouldn't even recommend a ssd, just 2 hdds in raid (not 0 of course...)

Well, the choise is yours then I guess...

Since i already have an 1TB SSD why would i buy an HD?

I understand your point but, i have this one already

then I just wouldn't get another one...

but that's my opinion, they may vary

because ssd's aren't meant for backing up. as simple as that

I have around 450GB used in this SSD.

But i usuallly download a lot of TV Series and movies.

but for backups ssd are much more expensive with basically no benfit, and ssds may die sooner with no power. If your just storing backups just get hdds.

The problem of HD is the Slow readings and writes.

 

Which HD would you recommend? If it's not much expensive i'll get both
