HDD: Any quality difference between portable and plugged in external HDD? (lemmy.org)

I am debating between those Western Digital portable drives that go up to 5tb that function with USB only (WD my passport) and the bigger ones (eg my book) that are bigger and need power outlet besides the USB connection.

Is there any difference in quality or durability to store media?

SMR in those. Also typically 5200RPM vs 7200RPM speed.

From experience I can say you can’t reliably play back high bitrate content from those. Read and write speeds get bad after you’ve used 1/3-1/2 the drive. Oh 8-14MB/s should be fine. But forget playing a 4K encode at 20MB/s with a 2MB/s audio track.

As backup drives they’re acceptable as long as you can accept much longer write times to refresh data.

Bigger drives with power supplies generally are 7200RPM. Many of the lower capacity ones (under 14TB) are still SMR but you should be able to play back higher bitrate content and get a bit better read/write performance.
