Stable-state drives are sooner, quieter, and extra power-efficient than onerous disk drives.
In most conditions, selecting an SSD is the apparent name. However there are nonetheless a handful of circumstances the place HDDs make extra sense — not due to nostalgia, or as a result of they’re “ok,” however as a result of they’re the higher instrument for the job.
You want a variety of storage, and you do not wish to spend some huge cash
Storage price effectivity
Storage pricing has shifted dramatically in favor of SSDs over the previous few years. However HDDs nonetheless maintain a major cost-per-gigabyte benefit at excessive capacities, and that hole issues while you’re shopping for in bulk.
A 4TB HDD will set you again round $80-120. A 4TB SSD will price you not less than 4 occasions that on the time of writing, if no more. Should you’re constructing a house NAS or media middle and also you want greater than a single drive, your total price will rapidly climb into the a number of hundreds with SSDs.
The kind of information you are storing does want consideration; long-term information storage backups usually do not want the blazing-fast information speeds related to SSDs. This implies you may get away with a a lot bigger array of HDDs with respectable information speeds whereas saving your self a small fortune within the course of.

The Seagate SkyHawk 4TB is a surveillance-optimized 3.5-inch HDD constructed for twenty-four/7 video recording programs. Utilizing ImagePerfect firmware, it helps a number of HD digital camera streams with decreased body loss. That includes SATA 6Gb/s, 64MB cache, and enhanced sturdiness, it’s perfect for DVR and NVR setups requiring dependable, high-capacity storage.
You are constructing a devoted up drive for long-term storage
Does it should be as quick as your major?

Now, following on from that time, there’s a false impression about backup drives, which is that they should be as quick as all of your different drives. However the actuality is that if it is a drive you are utilizing for long-term storage, you merely do not want the identical speeds.
HDDs make glorious devoted backup drives for a number of causes. First, the cost-per-GB benefit means you possibly can afford to maintain extra backup historical past — a number of full system pictures, versioned file backups, or redundant copies.
Second, HDDs are well-understood. Their failure modes are predictable, their SMART diagnostics are mature, and restoration choices when one thing does go unsuitable are sometimes extra established than with failed flash storage.
There are additionally some concerns to bodily, spinning drives versus SSDs, which may encounter information retention points once they’re left unpowered for lengthy durations. That is to not say that HDDs haven’t got points: disk platters, mechanical arms, and bearings can seize, and unintentional impacts may cause enormous issues.
But when your purpose is long-term information backup, an HDD is what you want.
You are working a NAS with a number of drives
HDDs nonetheless win right here

Community-attached storage (NAS) gadgets are one space the place HDDs nonetheless dominate — and for good purpose. NAS setups are usually used for media streaming, centralized file storage, or dwelling server purposes the place sequential learn efficiency issues greater than random entry velocity, and the place whole capability is the first metric.
NAS-specific HDDs like Western Digital’s Crimson Plus or Seagate’s IronWolf traces are constructed for twenty-four/7 operation, deal with the vibration that comes from being housed alongside a number of different spinning drives, and assist options like rotational vibration compensation. They’re purpose-built for precisely this setting.
Filling a four-bay NAS with SSDs would price considerably greater than filling it with NAS HDDs, and in most dwelling or prosumer use circumstances, you’d by no means discover the velocity distinction. Streaming 4K video, accessing a Plex library, or syncing information throughout an area community does not require SSD learn speeds. It requires dependable, always-on storage at an affordable value.

HDDs are removed from lifeless. I exploit a combination of SSDs and HDDs on my dwelling pc for precisely this purpose. My working system and regularly accessed media like video games and so forth are on super-fast PCIe 4.0 SSDs, whereas my long-term backups and media servers use onerous drives.
However for many dwelling customers constructing information backups and media servers at scale, HDDs are the best way to go. You will find yourself with a lot higher capability at a decrease price, and doubtlessly with higher information restoration choices, too.
