I admire the courage to store data on refurbished Seagate hard drives. I prefer SSD storage with some backups using cloud cold storage, because I’m not the one replacing the failing hard drives.

Every drive is "used" the moment you turn it on.

There's a big difference between used as in I just bought this hard drive and have used it for a week in my home server, and used as in refurbished drive after years of hard labor in someone else's server farm

Drive failure rate versus age is a U-shaped curve. I wouldn't distrust a used drive with healthy performance and SMART parameters.

And you should use some form of redundancy/backups anyway. It's also a good idea to not use all disks from the same batch to avoid correlated failures.

datablocks.dev has a page explaining what white label and recertified disks are [1]. Those are not disks used for years under heavy load.

RAID. Preferably RAID 6. Much, much better to build a system to survive failure than to prevent failure.

Enterprise drives are way different than anything consumer based. I wouldn't trust a consumer drive used for 2 years, but a true enteprise drive has like millions of hours left of it's life.

Quote from Toshiba's paper on this. [1]

Hard disk drives for enterprise server and storage usage (Enterprise Performance and Enterprise Capacity Drives) have MTTF of up to 2 million hours, at 5 years warranty, 24/7 operation. Operational temperature range is limited, as the temperature in datacenters is carefully controlled. These drives are rated for a workload of 550TB/year, which translates into a continuous data transfer rate of 17.5 Mbyte/s[3]. In contrast, desktop HDDs are designed for lower workloads and are not rated or qualified for 24/7 continuous operation.

From Synology

With support for 550 TB/year workloads1 and rated for a 2.5 million hours mean time to failure (MTTF), HAS5300 SAS drives are built to deliver consistent and class-leading performance in the most intense environments. Persistent write cache technology further helps ensure data integrity for your mission-critical applications.

Hello, author here! It's a nice surprise to notice my own post here, but the timing is unfortunate as I'm shuffling things around on my home server and will accidentally/intentionally take it offline for a bit.

Here's a Wayback Machine copy of the page when that does happen: https://web.archive.org/web/20251006052340/https://ounapuu.e...

OT > Half of tech YouTube has been sponsored by companies like... It just struck me that the product reviews are a part of the social realm that is barely explored. Imagine a video website like TikTok or YouTube etc where all videos are organized under products. Priority to those who purchased the product and a category ranked by how many similar products you've purchased. The thing sort of exists currently in some h…

The reason you don’t see videos arranged by product is because everyone knows not to trust unknown creators telling you how great a product is. Viewers want to see opinions from specific people they’ve come to trust, not the first video that comes up for a product.

Coincidentally or not, those folks who have more subscribers usually charge more for their consideration. That’s why I generally trust Steve of Gamers Nexus more than other folks, because they don’t do ads except for promoting their own products, so there’s no conflict of interest. On the one hand, Gamers Nexus doesn’t manufacture their own hard drives, but on the other, they publish their methodology and have a reputation to uphold, so I would trust their judgement regarding testing computer hardware more than folks who do engage in outside advertising.
