Hello WD community,
I’m having the problem that loading some Samples into RAM is done at a “whopping” speed of about 10-20 MB/s.
After trying a few solutions from this forum and other internet sources (full list at the end), I ran my own tests to further isolate the problem.
So I tested copying some files and found the following:
copying proprietary .nki files (Native Instruments Midi Sample files) from the Western Digital SSD (WDC WDS500G2B0A-00SM50) to a Crucial SSD (Crucial CT525MX300SSD1) matched the problematic 10-20 MB/s reading speed
copying equivalent big .iso files with the same SSD configuration is done with average ~450 MB/s
These measurements were taken using Western Digital’s Dashboard software. In addition, I roughly double checked the read/write speeds by also measuring the time.
So I do believe, that the type of Data is the root to this problem.
Is this a known problem I have to live with, or is something wrong with my SSD?
Is this odd behaviour due to SSD and data architecture?
Is there any way to solve this issue?
I am quite confused and lack the knowledge to understand more deeply why this is happening. Also, I don’t find very much on forums about this specific problem, so I hope someone here can give me some insight.
Thanks so far for reading, I am looking forward to your ideas!
List of checks and changes:
- The Dashboard software from WD states, that the SSD Health is in normal condition and the firmware is up-to-date. There seems to have been no firmware update ever, because no firmware change was done by myself. I don’t know if an automatic system did a firmware update by itself, but I am doubting it.
- both SSDs are formatted in NTFS
- both SSDs are connected internally to the southbridge SATA 6 GB/s connectors
- both SSDs have more than 25% free space (SSD1: 28%, SSD2: 39%)
- Trim is enabled
- I changed from native IDE to AHCI. That did improve the measured value for the disk sequential read from 120 MB/s to about 231 MB/s. (measured with the “winsat disk -seq -read -drive X” command in the powershell)
- implemented exceptions in Avast Antivirus for the folders
- disabled “Windows write-cache buffer flushing”
- disabled “Windows write caching”
- OS: Windows 10 Education, Version 20H2
