Need advice on M.2 with PCIe

Hello, please advice on upgrade from SSD SATA to m.2 PCIe.
Goal: the get meaningful speed increase from SATA 250G Samsung EVO
to some m.2 500G

hardware:
CPU i7-2600 , 1155
MB: ASUS P8B75-M with no M.2. There are
1 x PCIe 3.0/2.0 x16
1 x PCIe 2.0 x4
2 x PCI

I am thinking about:

StarTech.com M.2 Adapter – x4 PCIe 3.0 NVMe
https://www.amazon.ca/StarTech-com-M-2- ... B01FU9JS94

and 207$ WD-Blue (m.2, 2280 whatever it means), can not find speed
https://www.amazon.ca/WD-BLUE-CSSD-M-2- ... B073SBX6TY

or 250$ Plexator, NVMe 2,000/1,400 MB/s
https://www.amazon.ca/Plextor-PX-512M8P ... 01JCXXYMQ/

or 283$ Samsung ,m.2, 2280 Up to 540MB/s and 520MB ??? really ????
https://www.amazon.ca/Samsung-850-EVO-I ... 00TGIW1XG/

Questions:
Q1: what is the difference between m.2 2880 and M.2 PCIe as in the link:
https://www.wdc.com/products/internal-s ... DS512G1X0C

Q2: m.2, 2280 often reported as having 540 read/write. But it is
ordinary speed of SATA-III-SSD. Where is 2.5/1.5G speed?

Q3: is selected adapter good for given MB? Adapter is PCIe3x4, MB has PCIe3x16, it is OK?
Also: Is oldish i7-2600 good for targeted high-speed?

Q4: is "NVMe" necessary to get high speed > 540M/s ? Plexator is reported as NVMe but Samsung -- not.

Q5: any related advises are welcome. another adapter? another ssd?

Thanks in advance.

Alex.

1) M.2 is the form factor 2280 is the size (80mm length), there is also 2260 (60mm length), and 2242 (42mm length).
2) M.2 is the connector format it is available in SATA and PCIe, those drives are using the SATA connection
3) x4 will get you the full speed
4) Yes it means it is a PCIe drive
5) Depending on what you are doing you may not see a dramatic difference so temper your expectations (it won't be like going from HDD to SSD). Generally people don't do large sequential reads/write so the huge 2.5GB/sec ratings don't mean much (4K Random is a better metric). Having said that most of the high end drives of today are all NVMe.

Thanks tkyoshi! from you explanations I got the following:

1. i7-2600 + P8B75 + selected adapter are OK to get >540 M/s
2. For >540M/s I need NVMe that also called m.2-PCIe

It is my "new technology testing" computer with
latest Oracle, SQL Server, Visual Studio, BI tools, database tools,
Office, virtual machines, etc. Of course, SSD from HD was
huge improvement. It would be interesting to see an effect of
next speed range of storage.

Thanks,
A.

1) Yup!
2) Yes!

Also for best performance don't forget to download the latest NVMe driver from your SSD Manufacturer.

You won't be able to boot with a NVMe SSD on a motherboard that old unless you are able to modify the BIOS to include the proper boot ROM.

This. Big advantage of NVMe is that you'll have speedier boot but on a board that old you probably won't be able to boot from it.

This.

B75 doesn't have proper NVMe support. You'll need to add the NVMe modules into your BIOS with some UEFI editors.

If you don't even know what NVMe is, then I doubt you'd be comfortable modding your BIOS.

Doh, Yeah sorry my bad forgot to mention this. Thanks!

But yeah you can still use it as a secondary drive for your work and keep your existing Samsung as the OS drive.

However there is 1 drive I know, the Samsung 950 Pro actually has a Legacy nVME Option ROM on board. If you put your boot mode into Legacy it will pull this off the drive and allow you to boot on a system that doesn't natively support NVMe. Unfortunately the 960 Pro/Evo do NOT have the Legacy Option ROM on board anymore.

burnt69, board123 -- thanks!

Yes, I am not comfortable to play with BIOS.
So, for this computer I wait Black Friday special on Samsung
SATA EVO/PRO 500G

Still, NVMe idea is already in my head, so, probably it will
happen with my another comp : i7-4700 H97M-E.
ASUS reports there is M.2 SATA/PCIe slot and
people say ASUS 9-series are supposed to support PCIe boot.

Have a great day!
Alex.

Keep in mind 950 Pros run hot and are prone to thermal throttling If hammered continuously. Being that yours is a desktop you can probably find a decent way to keep it cool.

The new models still thermal throttle but you can push a lot more data through them before they start to pull back.

Better idea. Trying to retrofit an NVMe drive onto an old sandy bridge platform is a waste of time IMHO.

Nah, its a good learning experience, the B75 isn't "Sandy Bridge", but rather is Ivy Bridge, and the extra performance can be useful since the CPU's themselves aren't really any faster.

I guess he was referring to the CPU OP has Installed which is Sandy Bridge. But the 2600 is still a solid CPU.
