If you have a NAS server, you should definitely install the correct hard drive. The long term can save you a lot of nerves, time and money. We reveal what you need to look for in NAS hard drives.
What used to be the Picture, music and video collection in the photo album on MC-cassette, CD and DVD was, today is the own network attached storage (NAS). More than ever now gathering many digital data in households to. Then who buys a NAS, now the question arises: &# 8220; And what disks do I need?&# 8221;721794network Tips
Hard drives for NAS: desktop hard drives are unsuitableFor a NAS their so-called NAS hard drives should be used. Source: Amazon*
In principle, you can each hard drive in a NAS servers use Depending on the selected RAID type you have then a subset of the available storage capacity.
BUT: Desktop hard drives are not suitable for long-term use NAS. You can get a defect very soon. Moreover, not all have the necessary holes for mounting in a NAS. Also of SSDs is not recommended. Better it accesses so-called NAS hard drives:
- NAS hard drives are designed for continuous use.
- NAS hard drives have a special firmware that is designed to minimize the vibration of the plates.
There are now only three hard drive manufacturers in the world: Western Digital, Seagate and Toshiba. All other names are trademarks of just three manufacturers. These are the rows of the available NAS disks (beginner to semi professional):
- Western Digital Red *
- Seagate Iron Wolf * (Formerly NAS HDD)
- HGST Deskstar NAS *
Our tip: Seagate can be found often larger capacities at relatively cheap prices. From our own experience we can turn the hard disks recommend Western Digital RED, as they now already three years do their job without any problems. The variant WD Red just fine with us. Otherwise, there's WD Red Pro.

What size and storage capacity is to have the NAS hard drive?
In today's NAS systems you can indeed install the smaller 2.5-inch hard drives per adapter, but we recommend the usual 3.5-inch hard drives, as the bigger versions usually have more capacity, are cheaper and in NAS themselves are not much louder.
When the storage capacity you need to consider: If you want to be future-proof, it should be today, for example in a NAS with two hard drive slots have at least 2 x 4 TB hard drives. Because if you activate the fail-safe RAID 1, you remain as 4 TB at leisure.
Who has a very large collection of data or produces very large files daily or receives should choose equal a 4-bay NAS may. This can you upgrade and expand your space so gradually with more hard drives. Therefore, you must there not choose to large hard drives. You can use, for example 4 x 3 TB hard drives. Then you have with RAID 5 still 9 TB available. That should be enough for a while.
Cheap and reliable (own experience) NAS-level models are:
- Synology DS216j (2-bay NAS) *
- Synology DS416j (4-bay NAS) *
Is the rotational speed at NAS hard drives important?
NAS hard drives usually have a rotation speed of 5400 revolutions per minute / transferred as in Windows with a maximum of 120 MB s. For desktop hard drives are often 7200 rpm. but the difference is hardly noticeable because you would notice a speed advantage only when copying large files, and then only if your network would be faster than 1 Gbit / s (which it but probably is not). When streaming video to the increased rotational speed does not matter.
Conclusion to NAS hard drives
- Searches for NAS hard drives for your server.
- how much memory you will need in the future and also note that you have less available space with activated RAID estimates.
- The rotational speed of NAS hard drives can be neglected especially in the private sector.
- SSDs bring almost no advantages in a NAS and are quite expensive.
