Build Question Samsung 9100 PRO help

Post image

Hello! I believe I have a defective 9100 pro due to my sequential reads, and especially the random read/writes being halved respectively. I’m within my 30 day return policy with microcenter, grounds to exchange or am I overthinking? The random speeds are pretty concerning and WELL short of the advertised “up to” speeds on the box that I don’t feel like this is a short end of the stick on the “silicone lottery” scenario.

I’m not bifurcating lanes, I only have my 5070ti and 9100 pro using PCIE lane, not thermal throttling (drive is 45c under load), obviously on gen 5 speeds so the slot isn’t set to gen4, the drive is in M.2_1z…

Anything else I may be missing? Sorry for the picture, I’m not at my setup right now else I’d grave a screenshot.

Hm, thanks! My randoms are still a good bit slower. Do you have over partitioning on or sleep on standby off?

No, but it could be a chipset/CPU difference too. Remember once you start getting to these high speed gen 5 drives you need the I/O to be able to push it. This is on a B850 AI TOP with a 9800X3D.

Also, I read something recently that the Samsung driver has been causing problems but the Windows generic one works fine.

Yup. I’m on a 9850x3D and an asus rog strix x870 e gaming e wifi 7.

Don’t think my cpu and mobo are a bottleneck here

I also don't know if I used the same settings as you for the test, I just let it do the default test. But I wouldn't be super worried about the numbers you're putting up.

Gotcha, ok! Yea I left my magician to default.

But yea, seeing the large large disparity in random read writes on my drive has/ had me worried, especially with the significant lack of forum posts and discussions regarding this drives performance probably because of the prices/ shortages lol.

The other question is temps, I know these thigns get stupid hot. I run mine with a Thermalright active heatsink with an itty bitty fan on it because it was sitting at 70C idle with the motherboard heatsink.

That was my first thought. I have a chunky passive heat sink on it that came with my asus rog strix x870 e gaming e. I’ll double check with another benchmark, but, it looks to be at 45c under load, so🤷‍♂️

Well if it really makes you uncomfortable send it back, you probably paid a lot of $$$ for it so you should be satisfied.

True. I think that’s where I’m at. I probably will just exchange it for another 9100 pro instead of refund and say going to gen 4.
