Enterprise drives with "power disable" in a synology? (alien.top)

Hi friends. I am looking to up my 8TB drives to 10TB drives in my 2 bay synology? Looking at Amazon they have refurbed enterprise drives for $75 but they list a "power disable" drive. I am not sure what that means. Does it have an adapter that attaches to the drive between the sata power connection and the MB sata power connection? Does this rule out working in my synology or drive enclosures that have a backplane for the connection?

Power disable enables the host to power cycle the drive without power cycling itself or you pulling and re-seating the drive.

The downside is that when plugged into "legacy hardware" that does not support this feature you cant give it 3.3v.

Thats why you often see people taping a few pins on the drives power connector or using molex->sata adapter cables that does not power these pins.
Since you often get ultrastar enterprise drives with this feature when you shuck.

It depends on your specific model of Syno, but many backplanes are Molex-powered and also do not provide power on the 3.3v pin to the drive, thus avoiding the PWDIS issue.
