I have a *Synology DS418j* NAS and have 2 of the hard drives installed at 2x https://www.digitec.ch/de/s1/product/seagate-ironwolf-10tb-35-festplatte-5961183 and since I installed the last one and my data is now on all 4ren it spacks around, I don't know why, can it be that the two hard drives are not compatible with my NAS ? or with the other two hard drives ? So it loads slowly, opens the folder slowly and before I could watch a movie over the NAS without any problems, now it hangs all the time and reloads, but when I go into the NAS settings it says "Ram 45% and CPU 14%" utilization in the resource monitor, can something be wrong ...?
Yes
**The HDD is recognised as compatible according to the manufacturer, as others in the series have passed the compatibility test.
Please note that the firmware of HDD/SSD may be updated or changed by the manufacturers without prior notice. Synology can therefore only guarantee compatibility with Synology products for the firmware versions listed here.
This drive is only compatible with Synology servers with the hard drive carriers shipped since June 2014.** that's what it says with the hard drive, see screenshot:

I read through the list and some hard disks do not tolerate the sleep mode, I turned it off and now it runs quite stable .... don't know if that was the reason ...?
