Question Recommendation for a PCIe to M.2 Expansion Card for Asus B85M-G R2.0 Mobo

There are PCIE x1 slot to m.2 adapters such as this one. Can’t guarantee that your BIOS will support booting from it though - nor support it at all.

1x PCIE 3.0 channel supports a theoretical max of 985MB/s. SATA3 is 600MB/s. Not much of an upgrade. So I agree with the others, just stick with SATA for a motherboard of this age and feature set. It’s guaranteed to work.

Edit: just checked your mobo manual, the PCIE x1 slots are Gen 2. So actually slower than SATA3 ports at 500MB/s 🤔

Thanks for the information.
 
No I would have to buy one.
Ok.

Here M.2 PCIE x1 adapter - for installing in x1 slot.

Here M.2 PCIE x4 adapter - for installing in x16 slot.

Note #1 - You'll have to keep your sata drive for bootloader.
You can install windows on M.2 drive.

Note #2 - Windows 7 doesn't have native support for NVME. It needs several hotfixes and NVME drivers to be integrated into install media. Install windows 10 instead.
 
I agree going with Sata 3 SSD. It's the 'no moving parts' factor that make SSDs fast. Sata SSD and Pcie Nvme access times are instant, it doesn't matter how it's connected, Sata cable or M2, random access is the same. Throughput as in file transfers is faster with Pcie, that's true, but how often are you going to be copying large files where 3500MB/s is going to be the difference vs 600MB/s for you? If you want the snappy performance SSDs give for general use / loading Windows and programs then throughput isn't the answer, random access is.

Many thanks SkyNet. That's what I've got installed running off a SATA HDD is Windows 10 64 bit Home.
 
For a motherboard that old, I still recommend a 2.5" SATA III SSD
I'll give that a try but considering the age of this motherboard the SATA SSD should boot (detected by the BIOS) once I've installed Windows 10 Pro on it yes ? Also will the performance of the SATA SSD be marginal over a 5400RPM SATA HDD ?

Your motherboard will certainly be able to boot directly from a 2.5” SATA SSD. I used to boot an ancient i7-870 system from 2010 using a SATA SSD, as well as a Core Duo laptop.
