[SOLVED] ADATA XPG SX200 Pro 512GB running a half speed

[paddybliss]

I’ve just built my first PC and have been running some tests to check everything is working as it should be. All seems good apart from my my 512GB ADATA XPG SX200 Pro NVMe drive, which is running at nealy half the advertised speed (and perhps 60% compared to real life benchmarks):

CrystalDiskMark Default Profile (similar results with other profiles):
[Read]
Sequential 1MiB (Q= 8, T= 1): 1724.685 MB/s [ 1644.8 IOPS] < 4858.56 us>

Random 4KiB (Q= 1, T= 1): 174.943 MB/s [ 42710.7 IOPS] < 23.27 us>

I've run this over and over agaIin with different profiles and swettings and the results are nevery very different. I have seen a few other threads on here regarding this device, but this is a slightly different set of results to others. The write speed isn’t a low as some have reported, but still slow, and the read speed is way slower than others.

My system is:
Asrock B450M Pro
Ryzen 5 3600
GEIL EVO II 16GB
HP NVDIA Geforce GTX 1060

The ADATA drive is my primary boot drive with a fresh installation of Win 10 Pro. It’s installed in slot M.2_1, which is PCI Gen3x4 and should give speeds up to 32Gb/s. Windows reports that the drivers are up to date.

I’ve also:
Ran System optimization (TRIM) in the ADATA SSD Toolbox
Checked that write caching of device was enabled

As this is my first PC build, so hopefully there's just something obvious that I've missed?

Solved it!

I sent these benchmarks to WD, who asked me to send event viewer and msinfo reports. They got back to me with:

“Based on the information you provided, it does appear that the partition is not 4K aligned. This kind of issue can be caused by bad cloning or OS installation and can affect the drive's performance. Unfortunately, we are not able to assist with correcting this issue. But there are third party utilities that you can look into that should be able to correct this issue without needing to re-partition the drive”

A quick google and I was able to fix it following this guide:

How to Speed Up Your Solid-State Drive by Re-Aligning Its Partitions

If you've migrated your operating system from a mechanical hard drive to a solid-state drive, the partitions may not be properly aligned.

Thanks everyone for your help with this.
