Slow Raid 0 with Windows 10

[Phillip_Sam]

Hi guys

I have 4x WD Black 2TB in Raid 0 for my media storage.

Normally, when I transfer movies from the raid to my Samsung T1 1TB external SSD, it writes with +/- 350MB/s.

Since Windows 10 it only writes with +/- 100MB/s. But only if I copy the movies from my raid 0.

It's the same if I copy movies from my Raid 0 to any other SSD in my PC (Samsung 840 evo 500gb, 850 evo 500gb, 850 pro 250gb). I always get only +/-100MB/s.

But programms like AS SSD tell me, everything is fine with my raid and I get the usual 300-400MB/s read/write speeds.

Does anyone know the solution to my problem or has similar problems with his/her raid 0 since upgrading to Windows 10?

Cheers,

Phil

You might check chipset drivers for Windows 10 if there are any. What are you using to run the RAID array? On board Intel RAID?

Already checked. Nothing new found.

It seemed to work for a while (went to 330MB/s) and then back again to 80-90MB/s after about 5min.

Maybe my specs will help:

- i7 4770

- Asrock Z97 Extreme 9

- 4x WD Black 2TB

- Samsung 840 evo 500gb, 850evo 500gb, 850 pro 250gb

- Superflower 1000W

- 2x r9 290 Crossfire
