Any ol' HDD will do. If you don't have any lying around, then all that matters is what you're willing to pay, and what drives the price is size. All brands are equally excellent, so get the cheapest that meets your size need.Stone Man wrote:That's very nice to know. Can you suggest any cheap HDDs that will get the job done? Price is more of a matter than size. I only have 25GB worth of data.Swiftek wrote:I use this to save wear on the SD card - which doesn't like lots of writes - and to prevent corruptions that seemed accompany that. Since I moved to a HDD, I've had no more long-term system problems. My server runs 24/7, and the SD cards didn't seem to like that.
If the price is too high for my taste, I don't mind finding or writing a script to reboot the system every night at midnight.
I use my Pi as a central file server, torrent seedbox, and a public facing web server, so I have two 2-TB HDDs with one running the system and both housing our vast media collection of movies, music and software archives for network access. I run Raspbian with Samba for local file sharing, and a LAMP stack for web serving.
I mostly use NewEgg.com when I'm bargain hunting, and below is a good example of a cheap drive that will likely do all you need, and the enclosure that I'm actually using on an older B model Pi. Generally, any SATA HDD will work with any SATA enclosure, but the Pi can be finicky about the enclosure. Another important requirement - beyond compatibility - is that the HDD enclosure have its own power supply. You can't rely on the power coming from the Pi's USB ports (a common mistake/failure in the Pi universe).
