Copy or Moving starts at 300MB/s for a couple seconds and then goes to 30MB/s. Sometimes even 1.xx GB/s. And goes to to 20 - 30MB/s.

I get 544MB/s read, random is 85907 IOPS and 520MB/s write, random 68581 IOPS.
The HDD I'm copying does 59MB/s, random is 159 IOPS, and 60MB/s, random 448 IOPS.

Is the HDD I'm copying throttling the transfer speeds?

If so can someone recommend the best HDD 1-3TB under $150. Like don't recommend based on internet searches, but on real world experience please. Where you own the drive and know 100% that it is reliable and fast.

I was copying to the HDD from the SSD. About 20GB file to test the speed over a period of time. ETA was approx. 10 min.

I'm considering a external drive but don't know if the speed is good enough vs an internal. All the reviews, comparisons I see contradict themselves. I rally don't want a moving HDD because my brand new HDD that was like 11 months old stop working out of nowhere. Checked warranty and it was expired so I opened it up and the needles where a bit crooked. So I'm guessing it was scratching the plates.

I don't ever want to experience something stupid like that so I'm really gearing towards a drive with no moving parts. Main reason I got a SSD in the first place.

Anyways sorry for the rambling I just want something that is reliable and wont mess up. Thanks.
