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.

Take a look at backblaze data stats. Consumer drives are just as durable, if not more so than enterprise drives. The biggest thing you're getting with enterprise drives is a longer warranty.

If you're buying them from the second hand market, you don't likely get the warranty (and is likely why they're on the second hand market)

There isn’t a significant difference between “enterprise” and “consumer” in terms of fundamental characteristics. They have different firmware and warranties, usually disks are tested more methodically.

Max operating range is ~60C for spinning disks and ~70C for SSD. Optimal is <40-45C. The larger agents facilties afaik tend to run as hot as they can.

> drive has like millions of hours left of it's life.

It doesn't apply for the single drive, only for a large number of drives. E.g. if you have 100000 drives (2.4 million hours MTTF) in a server building with the required environmental conditions and maximum workload, be prepared to replace a drive once a day in average.
