4-pin JST-XH connector specs and staggered HDD spinup with LSI SAS 9211-4i

[Gian]

Hello.

I would like to know what is the maximum amperage of the 4-pin JST-XH connector since I am planning on powering 4 HDDs by means of it as well as whether it is possible to set up a staggered spinup configuration with the LSI SAS 9211-4i host bus adapter.

If the 4-pin JST-XH connector output current allows it, the project would entail splicing together two Pine64 power splitters somewhere between the cable input connector and the (seeming) buck converters.

Any advice on a suitable 230V 50Hz AC/DC PSU would also be appreciated.

Thank you.

As an alternative to the above-mentioned HBA I have just discovered the ServeRAID H1110 which has a better form factor, so the same staggered spinup question applies to it.
