NAS drives and DAS drives. You may well have heard these terms bandied around when you have been choosing your computer storage. But what is the difference between these two systems and what do you actually need for your PC?
Whether you need additional storage (for a growing movie library or so that you have a secure place to store important documents) both NAS and DAS offer great solutions. In this article we’re going to give you a basic guide as to why. Let’s start with simple explanations of what DAS and NAS are…

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 or flash drives.
NAS (Network Attached Storage)
NAS means storage devices which connect to a network. They allow multiple computers / devices in a network to share the same storage space at once.
Why choose DAS?
DAS is the most basic level of storage. 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. This is correct whether talking about simple flash drives for small amounts of easily portable data right up 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 a location without internet access, on transport or for keeping secure and sensitive data.
DAS drives can be used to work with single devices as a back-up 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. The user doesn’t need to access information via a network so there is less chance of data being accessed when it shouldn’t be. 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 physically connected. In effect this 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 physically tied 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 means that users can easily upgrade storage without having to transfer everything across to a new and larger drive. Simply 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.
