NAS drives and DAS drives, you may have heard these terms bandied around when it comes to choosing your computer storage, but what is the difference between these two storage systems and what do you actually need for your PC?
Whether you need additional storage for a growing movie library or you need a secure place to store important document both NAS and DAS can offer great solutions.
Let’s start out with a simple explanation of what is DAS and NAS…
DAS- Direct-Attached Storage– DAS is computer storage that is directly linked to one computer or server, usually via a cable. This includes internal and external hard drives, SSDs flash drives.
NAS- Network Attached Storage– NAS are storage devices which connect to a network. They allow multiple computers/devices in a network to share the same storage space at once.
Why chose DAS?
DAS, is the most basic level of storage as your files are physically connected to the host computer. This gives the user a lot of advantages as the content and device is easily accessible.
The cost of DAS also tends to be much lower in comparison to NAS, whether this is from simple flash drives for small amounts of easily portable data, to much larger terabyte hard drives.
Users of DAS drives do not require a network connection meaning all the files and data can be accessed directly from the drive. This can be helpful if you’re in location without the internet, on transport or for keeping secure and sensitive data.
DAS drives can be used to work with single devices like as backup for a computer, as video storage for a TV or as a quick file transfer option for secure data.
Although DAS is technically a more basic format of storage, it can be inherently more secure as a user doesn’t need to access information via a network. This can be very important for companies storing critical data or professionals with access to personal information.
Why chose NAS
NAS drives are designed to give the user more freedom to update, access and transfer files.
As the NAS is connected to a network a user can access the NAS drive without needing to be connected. This effectively means wireless freedom, and in the generations of smartphones, tables and wireless media, the popularity of NAS is growing.
If you are a multi-user household or don’t want to be tied (physically) to a device, NAS drives allow for wireless connectivity over multiple devices at the same time.
Expandable NAS drives give you the option to add more hard drives to the NAS unit. This allows the users to easily upgrade storage without having to transfer everything across to a new and larger drive. Simple add more storage space if you run out.
NAS drives are a great option as a media archive, especially if you have a household full of wireless devices like tablet smart TVs and phones. You can simply stream movies, music and pictures direct from the storage onto your device with the need for messy wires and cables
