SATA

Mon Jul 16, 2018 11:24 pm

Hi all,

I have a Pi 3B+. I am thinking of setting up a NAS server, and was just curious, is there really any benefit to buying an external drive? For example, I am looking at a NAS enclosure on amazon, comes with fans, and is for SATA drives of course. My setup would be;
3.5' in NAS enclosure, going into a USB 3 Hub which is plugged into a USB 2 port, of course.

So is there any benefit to buying SATA drives rather than an external drive?

Thanks

An external USB drive consists of a USB-SATA interface and a SATA drive.

To connect a SATA drive to a RPi you would need a USB-SATA interface.

Why do you need a USB 3.x Hub etc ?? just buy a 2.5" External USB Drive, the RPi 1200mA total USB current should be sufficient to power the drive if the official PSU is used:

Most external drives, for example

https://www.amazon.ca/Seagate-STEB80001 ... 01HAPGEIE/

are not designed for continuous duty 24 hours a day 7 days a week. While the drives in a NAS may or may not be different, the power supply and thermal management definitely are.

If you build your own NAS using a Raspberry Pi you will need some sort of USB to SATA converter as well as 12V and 5V power. I've had reasonable luck recently with Western Digital Red NAS drives, but any similar drive should work as well.
