[SOLVED] Is it worth to add a PCIe adapter to M2 NVME disk?

[diegoalejo15]

Hi,

I have an WD M2 NVME disk connected to M2 port. Crystaldiskmark shows: read=2500, write=1000, which was surprising to me as my secondary SSD disk shows: read=500, write=500 and I was expecting them to by similar.
The question is is it worth to move the M2 to PCIe x4 slot? will I notice a speed increase? how much should I expect?
I have a gigabyte a320m mother with Ryzen 7 4750, DDR4 16GB

Regards

I think if you use an adapter on a different slot you won’t be able to boot from the drive anymore. The nvme drive needs to go in the proper slot that it was made for

added info: in the mother´s manual I see:
1 x M.2 connector (Socket 3, M key, type 2242/2260/2280/22110 SATA and PCIe x4/x2 SSD support)

This means that the M2 slot is equal to a PCIe x4 slot? I mean in speed

ok, good point, I guess it can boot from that port but how to be sure? tha manual doesn´t say it

You have this:

1. 1 x M.2 connector (Socket 3, M key, type 2242/2260/2280/22110 SATA and PCIe x4/x2(Note) SSD support)
   * Actual support may vary by CPU.
2. 4 x SATA 6Gb/s connectors
3. Support for RAID 0, RAID 1, and RAID 10
   * Refer to "1-7 Internal Connectors," for the installation notices for the M.2 connector.

(Note) Supports only M.2 SATA SSDs when using an AMD Athlon™-series/ 7th Gen. A-series or Athlon™ X4 APU.

Your WD ssd, what is the exact model?

if you use a pcie adapter in the mobo slot you won't be able to boot. period. try it and see. Just use the 1xM.2 port and get a faster SSD

it´s a WD250 nvme, it´s fast, I´m not complaining about it, just trying to get more speed, as everyone

I don't think using an adapter from a PCIe slot vs M.2 slot makes a difference with regards to booting. Especially when this guide is using an adapter.

However at the end of the day, I don't think it's worth it. The real benefit of going to an SSD over from say a hard drive isn't so much the bandwidth, it's the IOPS (or 4K random bandwidth in some benchmarks). Most things that get pulled from storage tend to be small in size.

Gigabyte technical support´s reply:
If you add it to the first x16 and it´s a raiser/ adapter, it will work without problem.

And what benefit might you gain, over where it is now?

before asking in this forum I thought that it would speed up disk opeations.

Your motherboard M.2 port is a PCIe 3.0 x4.
Unless your drive were a PCIe 4.0 (it isn't)...the port speed controls the connection.

What specific WD drive is this?
Model num, please.

And even if it were a PCIe 4.0 drive and port....the actual user facing difference is about zip.
