What's the difference between a $50 HDD and a $200 HDD? (lemmy.world)

Beginner question: Searching for my first dedicated server setup, and I have no idea what to look for in a hard drive. I see a huge difference between drives of the same capacity, so what makes the difference? I am looking to eventually have a media server that can run "-arr" programs, Jellyfin, Immich, sync music, books, etc.

What are the factors I should be paying attention to other than capacity? Is it a lot of branding and smoke and mirrors, or will I see a significant change in performance/reliability with different drives?

$150.

(Also usually speed and/or capacity along with higher quality components)

150$, sorry

Some hard drives are built for 24/7 operation. They have higher MTBF ratings and longer guarantees.

Hard drives are very different. Many of them waste energy, lie in the SMART log or just are weird (spin up and down, lose speed, get incredibly hot etc.)

Acronyms, initialisms, abbreviations, contractions, and other phrases which expand to something larger, that I've seen in this thread:

Fewer Letters	More Letters
NAS	Network-Attached Storage
RAID	Redundant Array of Independent Disks for mass storage
SATA	Serial AT Attachment interface for mass storage
SSD	Solid State Drive mass storage

4 acronyms in this thread; the most compressed thread commented on today has 9 acronyms.

Rpm is a thing to look at. A 7,200 drive is faster than a 4,200, but slower than a 10,000.

10,000 and 15,000 rpm drives were made obsolete by SSDs and were discontinued several years ago. They are slower than many modern 7,200 rpm drives.

As someone that works at a storage devices company - we do still manufacture 10K HDDs. They are faster than the 7200s of the same spec, by nature. All 2.5” drives for enterprise systems. And will actually continue selling them until ~2030. That said, they’re all but obsolete at this point, and aren’t really being developed on any more.
