Question about Red Plus - 510142

Hello. I'm a bit lost. My HD (10 TB, WD100EFAX-68LHPN0, S/N 7JJR5SGC, bought 2018 at Galaxus) from the WDEx2Ultra (2x10TB, Raid) hung up the day before yesterday. Message 1: Disk 2 faulty, error code 208 / Message 2: Drive in bay 2 failed, error code 201. Since then, strangely, I can't access any jpg, mp3, mp4, mov, etc. -files any more. I am now trying to buy a replacement HD and hope to fix the problem with the replacement. Now there are two products with 10TB: "WD Red Plus" and "WD Red Pro". Do I have to pay attention to anything? Are both compatible? The differences are in direct comparison (what I can see at least) only in the transfer rate, weight and standby power consumption. I would be grateful for any expert advice! :-) Thanks in advance! Martin
