A well respected streamer builder ( Innuos) use Western Digital Red drives, and have done for years.
Says something for reliability. You can buy any drive and stick it in any kind of case you want, from a NAS system, to a portable USB case.
I have a couple of 2TB Seagate USB HDDs that are just over a year old. I’ve had so many failures with USB drives over the years that I do not trust anything. I’ll replace the Seagates before too long. Stuff isn’t backed up unless you have at least two copies of the original IMHO.
This. I back everything on my Inuos up to a NAS and also to a pair of 2 TB portable HDDs. The NAS backup happens automatically. I do the USB drive backups on a Thursday and keep one in the office as a means to minimise my paranoia about re-ripping everything…
3000 CDs would fit onto 1TB, and that becomes more affordable for an SSD - less than half the price. But I would go for HDs in a NAS system, especially if there’s a freebie going! Bung that next to the wifi router.
Personally I’d go for a cheap(ish) NAS so that you don’t always have to have computer on.
In future you may want to use something other than your laptop as a source.
I use a Synology DS118 (one of the cheapest). Since I bought this there is now also a 119J and 120J. They don’t vary wildly. I think mine has a 2Tb WD “red” disk in it.
I have a Synology single bay NAS with a 3TB WD Red.
Mine has been perfect over the last four years my model is DS115 which was the latest incarnation at the time I bought it. There are regular updates released from Synology.
Don’t need the computer on and is more or less silent
I bought a 1TB Seagate SSD recently for £115. Very happy with it so far. The main reason being that my Lumin streamer was struggling to power a standard external drive via the USB. (I don’t use a NAS)
