Getting Linus to test something

[joe1234555]

Hello!

 

I have gigabyte Z68x-ud4-b3 motherboard and committed myself to have it serve me for 10 years.

 

I am looking into m.2 PCIe SSDs such as Samsung SM951 M.2 PCIe SSD (512GB). However, my motherboard only has PCIe 2.1 and not m.2 connectors.

 

Therefore the only solution for me would be to get a PCIe to M.2 adaptor and connect it to my PCIe mini slots.

 

Would be great to see Linus perform a benchmark on such adaptor on a PCIe 2 or 2.1 slot and compare it to an m.2 slot on a newer motherboard.

 

Will such adaptor and an older PCIe slot slow down the drive? Or considering PCIe 2 could still handle many latest graphics cards without reaching its speed limit, the speed will actually be un-affected..?

Can no other person do so? Can you not do it and return the product if it isn't to your liking?

Tech reviews are someones opinions on a product. Opinions vary person to person. Linus likes his Dell XPS 12. I fucking hate them with a passion. In the end, it's you that has to be happy with it, not Linus. So at the end of the day, your opinion matters, and his is shit.

In order for Linus to test something there needs to be a great demand for that product to be reviewed. I don't think you will have any luck with him other than users answering your question.

It looks like most PCIe-M.2 Adapter use a 4x connection.

a SSD like the Samsung SSD SM951-NVMe would therefore be bottlenecked, but not by much.

also I am pretty sure, that you won't be able to boot from such a drive.

I don't think that's an NVME drive.

since that is not a GEN3 carry-over mobo (PCIe Gen 2.0) the x4 GEN3 requirements
would not be satisfied and the performance would be half rated speed using an adapter
and SM-951 NVME drive. lots o'money for half of what it is supposed to do.

you'll have to use the x16 slots to get full GEN2.0 (short slots are x1)

 

 

I don't think that's an NVME drive.

 

there are actually 2 sm-951 drives
sm-941 ahci retail
sm-951 ahci retail
sm-951 nvme OEM

PCIe 2.0 4x max data rate is 2000 MByte/s

SM951 max read rate is 2150 MByte/s

I doubt it would actually half the performance ...

I don't know why someone would buy an extremely expensive SSD and cheap out on their motherboard/CPU

SM951 max read rate is 2150 MByte/s

well, i am basing the rate reduction on pcper testing on a GEN2 using an

intel 750 (PCIe) and overall speeds were reduced to 1.5GB/s (2.6GB/s GEN3)

on reads (using x16 slot). a 44% reduction in read speeds. pretty dern close to 50%.

 

 

With PCIe 2.0 the SSD 750 is capped at 1.5GB/s in both direction, fitting inside the expected write performance, but with reads potentially around 1GB/s slower.
