I invested fairly a sum in a pc with high specs, and acquired 4 14TB Toshiba MG07ACA14TE drives to make a Raid 5 array with a complete of round 40TB.

Now, the initialization course of takes 4 hours pr %.   That is proper.   A whopping 400 hours to finish.  This cannot be proper. 20 days!!

I’ve newest drivers from yesterday, newest OS, newest every little thing. 

Laptop is a I9-14900F with 192 GB ram, with quick M2-drives for system.

The whole lot is meant to be tremendous quick, however the RAID is so sluggish, even my 2017-computer operating the identical Intel raid is means sooner.

What could be the problem right here?
