Where to buy cheap HDDs in EU? (infosec.pub)

I'm sketching the idea of building a NAS in my home, using a USB RAID enclosure (which may eventually turn into a proper NAS enclosure).

I haven't got the enclosure yet but that's not that big of a deal, right now I'm thinking whether to buy HDDs for the storage (currently have none) to setup RAID, but I cannot find good deals on HDDs.

I found on reddit that people were buying high capacity drives for as low as $15/TB, e.g. paying $100 for 10/12TB drives, but nowadays it's just impossible to find drives at a bargain price, thanks to AI datacenters, I guess.

In Europe I've heard of datablocks.dev where you can buy white-label or recertified Seagate disks, sometimes you can find refurbished drives in eBay, but I can't find these bargain deals everyone seemed to have up until last year?

For example, is 134 EUR for a 6TB refurbished Toshiba HDD a good price, considering the price hikes? What price per TB should I be looking for to consider the drives cheap? Where else can I search for these cheap drives?

Ok my 20 and your 20 are not the same.

I was saying the large numbers didn't make sense if you don't have a large fleet of drives. Say you have ten servers, each with ten drives, and the MTBF is 100 million hours (yay, easy math!). That means that half your drives will have failed after 100k hours, or 11 years of use.

Some of the sites I have been looking at are saying that this number will increase significantly because 8 hours of daily use would give you about 33 years of use.

I think I like the annualized failure rate better, but I don't think either really tell a great picture.

I would rather if the annualized rate were recalculated annually.

Regarding the controllers, that has been nagging at me this whole conversation. Most SATA peripheral cards do not have heat sinks, but most SAS cards do. The SAS cards at least have a more rugged appearance.
