Slow NVME reads with Gigabyte Aero 15 XB

[Vonny232]

Hi Folks,

I purchased an Aero 15 XB (10th Gen/2070 super) laptop from Overclockers a few weeks ago.

I then bought an Adata SX8200 Pro 1TB NVME drive which I connected into NVME Slot 2.

If I perform Atto or CrystalDiskMark benchmarks, the read speed is < 50% of its advertised speed at 1300-1400MB/s while the write speed is a more acceptable 2300-2400MB/s.

If I look at the Atto results, it seems pretty clear the speeds are hitting some kind of ceiling for some reason.

CrystalDiskInfo tells me NVME 1.3 @ 4x so the speeds seem unusually slow.

Its worth noting the default Samsung C:\ drive which was supplied with the laptop works within specs at 3000 MB/s read and 2500MB/s write.

This is the 2nd drive, as Adata reccomended I return the 1st one as it may be faulty. Since the 2nd drive has exactly the same issue I think its something else causing this.

Please see screenshots for more info.

Any ideas?

No I haven't. Im aware of the different driver chip though (if that's the thrust of the video) though I cant see how that can cause < 50% read speeds.

Do you have a link to the video?

Im inclined to return the SSD for a full refund anyway, and try another brand as I am annoyed the Primary SSD works at the correct speed while the 2nd SSD doesn't (even though all lanes are active).

Surely folk on this forum have purchased a 2nd SSD for the Aero 15, and if so would know which ones work the best?

Yeah, I did all that. I know the SSD is correctly recognised as NVME 1.3 and that all 4x lanes are in use.

I swapped places with the two SSDs and the "problem" followed the Adata SSD whilst the stock SSD worked at full speed whatever slot.

I also removed the stock SSD altogether and did a fresh install with the Adata SSD and the speed tests were the same (less than 50% rated speed).

I think there's acompatibility issue, maybe a BIOS tweak will fix it but im done with Adata now and am returning the device via Amazon.

I am looking at the Crucial P5 or the WD Black NVME SSD instead as they are similar prices.

But ultimately, there *surely* must be someone who also bought an Aero15 who has been through this before and can recommend one which is known to work at full (or near-full) NVME speeds.
