Not the cheapest but comes with a fan that you can modify the grille to allow more airflow as mechanical hard drives should not get too hot (see Amazon reviews on modifications)
I have this... accidentally upgraded the firmware with drive connected and it swapped the fan to turn on when not connected (instead of fan ON with drive connected)
I submitted a support ticket with Sabrent and they were quick to respond with custom firmware upgrade and application to remedy the problem... contrary to what the Amazon reviews say (bad support)

Sorry have to retract that recommendation.

a review says it doesn't support pwdis so you'd have to use the kapton solution.
I didn't realize support was that spotty, it does work with my orico.

In a NAS with proper support or a rack enclosure in a Data center where these drives are intended to be used the enclosure would have labeled drive bays and the ability to control the power to this pin individually for each bay so you could go into some sort of management software and turn off bay 1 and then turn it back on to restart the drive. At power on, start with them all off and then turn them on individually or a couple at a time to spread out the start up power spike of dozens of drives powering on at the same time. What ever other scenarios you can come up with where controlling the power to a drive via software would be useful.
The problem is a power supply that uses the old standard that said 3.3v power is provided on this pin is used with a newer drive that uses the power disable feature that says when voltage is applied to this pin turn the drive off. If you have that combination you end up with a drive that never turns on. Consumer drives basically never support the power disable feature so you don't run into that with them. It's primarily an issue in this specific situation. People buying used enterprise drives which have the power disable feature, because it is useful in enterprise settings, using them in standard PCs or consumer enclosures/NASes that aren't setup to use the power disable feature and have a power supply that is providing the 3.3v of power. It can show up in a data center if they have old hardware that was based on the old standard and doesn't support power disable but I also expect most places to be cycling that old hardware out so not likely to run into it. We also obviously wouldn't hear about it and if they know it's an issue they can order versions of the drive without the power disable feature too.

They probably should have implemented it in the reverse fashion though, so that consumers wouldn't have to worry about it.
Use any tape (doesn't have to be kapton, I used blue painter's tape for years), snip the pin on the drive itself, or use a crimped (NOT molded) SATA-Molex power adapter and you'll never have to worry about drives vs your PSU again.
