Slow m.2 NVME Xpg Sx8200 Pro or normal speeds?

EspinalAndres

Greetings,

Need your help: I clone windows from an NVME kingston A1000 (480 GB) to a Xpg Sx8200 Pro (1TB) succesfully, i run CrystalDiskMark and get this:

Datasheet: I don´t know how to interpret this.

But this drive is capable of 3500MB and 3000 MB, is something wrong or is normal?

Datasheet is at QD32, not QD8. Higher QD (queue depth) means higher numbers. Notice that at QD1 (AS SSD) the numbers are significantly lower! You can test at higher QD, if the numbers are still a bit low there may be other factors involved. For one, Intel consumer motherboard (Z490) have storage all over the chipset unlike dedicated CPU lanes on AMD boards (e.g. X570) which adds a bit of latency (lower numbers) for example. A fuller drive will perform worse. Etc.

1-How can I test QD32?

2-By QD8, you mean SEG1M Q8T1 (the firts item) on diskMark?

3-This ssd is only 80% free of data.

You can change how CDM tests in its options somewhere, if not you can use an older version of the software that uses QD32. Alternatively there are other benchmarks that let you pick whatever you want depending on your skill level.

 

QD8 = queue depth or I/O depth of 8. More queue depth allows the controller to more optimally organize the I/O to maximize parallelism (interleaving) of the flash.

 

You tested the drive at 29% usage. Once a SSD has been formatted, used, written, etc., its performance will necessarily be lower than factory. This is especially true if it's the OS/primary/boot drive as there may be other processes leeching I/O. Keep in mind this is without regarding SLC caching which is fast but can be inconsistent depending.

is worst now.

My other NVME (kingston a1000) is running full speed, even more than expected speeds, I have windows on the XPG nvme, could windows hit so much its speeds?

Also be aware that everything over the chipset shares x4 PCIe 3.0 bandwidth I believe, so 3.5 GB/s is total for all devices. Not that it would necessarily impact a benchmark...just in general, sequentials aren't that important.

Hi, but how people can obtain those numbers (3500/3000)?

 

1- is it because of windows running on the same ssd? or because is not a clean windows install but a clone?

 

2- I'm mazed my old nvme Kingston A1000 is running faster than expected speeds (1500/900) on the other m.2 slot:

3-Should I exchange the slots between my two nvmes?

 

4-Should I perform a clean windows install?

 

I really bought this ssd for the espected speed 😂

Don't worry my dear child for the doctor has come to save you!

 

This is what I get with only Origin + NV control panel in tray.

Samsung EVO 860 - 500GB 2nd slot:

SATA is disabled in BIOS (because no SATA drives is installed)

Maybe try without SATA and let windows sit for some time 5-10 min before you test. You can try without network.
