To explain network attached storage adequately would require a lot of technical jargon. In a nutshell, an NAS unit is a small networking computer designed to store mass amounts of data that can then be easily shared between numerous computers all tied in to a single network. They are often organized into what are called redundant storage containers.
Still with me?
Basically, NAS is used in places where many computers work together, such as an office, for easy data transfer and server access, making the transfer of large batches of multimedia files fluid and rapid.

After reviewing the available NAS on the market, we decided that the WD Diskless My Cloud Pro Series PR4100 is one of the best options for pro home use and small businesses.
The problem is, different network attached storage can vary tremendously in speed, memory and ability. If you’re not sure what things to look for, this guide will come in handy.
Things to Consider
Picking the right NAS can be a challenge for anyone, even those who know what they’re looking for, because there are so many different competitive choices. But if you aren’t really familiar with network attached storage, the following points can help point you in the right direction.
1. Diskless Drives
The first thing you need to know is that most network attached storage are sold diskless, meaning you will have to purchase hard drive disks (HDD) separately. The cost of an HDD varies dramatically, but you can expect to pay between $50 and $100. Bear this in mind when shopping.
2. Processing Power
NAS are like personal computers in a lot of ways. Not only do they require dedicated hard drives, they also have dedicated CPUs, or computer processors. As you may know, quad-core is better than dual-core and 3.0 GHz is better than 2.2 GHz. NAS also utilize RAM (random-access memory) the way a computer does, and more RAM is always a good thing.
3. Connectivity
You wouldn’t buy a wireless router or a cable modem with poor networking capabilities for your office. Don’t make that mistake with your network attached storage. Different NAS are rated for different levels of internet connectivity. Just bear in mind that if you’re looking for incredible performance ratings, it’s going to cost you.
4. Bay Count
No matter how great your external connectivity and internal specifications may be, data storage is finite. If you run out of bays, you’ve got nowhere to go. You should have a good idea of your data storage needs before you purchase an NAS.
Pay attention to how many bays your network attached storage allows. You don’t have to fill up all those bays right away, but like any other business endeavor, it’s always a good idea to have room to expand.
5. Price
This is a whopper of a consideration. A run-of-the-mill NAS prices around $400-$500. You can get one for around $100 or less, or you can go big and spend $1000 or more. Price is an interesting consideration as far as NAS goes, because you really have to analyze your data and business needs very closely.
Spend too little and you can shoot yourself in the foot with an NAS that doesn’t meet your requirements. Spend too much and you can blow hundreds of dollars on features you don’t really need.
An NAS is just like a computer. You need to evaluate your individual and company needs before you commit to any sort of purchase. Anything else and you’re asking for a headache. Trust me; I’ve been there!

TerraMaster D5-300 5-bay DAS
Features
- Supports up to 40 TB of storage
- Utilizes RAID technology to secure your data
- Compatible for both PC and Mac
With the Noontec-TerraMaster, we enter the realm of serious network attached storage capability. This 5-bay can support an individual hard drive up to 10 TB in size, or up to 40 TB in combined hard disk storage, equal to five 8 TB HDD.
Not only does this network attached storage support standard hard drives, it can also equip solid-state drives (SSD), which offer significantly improved speed and data retrieval. Constructed with an aluminum alloy and with excellent built-in heat dissipation, this NAS is durable, quiet and offers great performance.
The DR-3500 is also outfitted with the latest USB type-C interface, allowing for new ways to establish connectivity. Utilizing advanced USB 3.0 technology, this NAS is capable of data transfer speeds up to 5GBs. Using SSD over standard drives will boost the performance even more.This NAS also utilizes a redundant array of independent disks (RAID).
I’m not going to go into detail about how RAID works (this isn’t a tech blog), but it offers superior support and protection for your data than a standard disk drive can provide, especially at high RAID levels.
Bear in mind that this is a diskless NAS unit, and you will have to purchase disk drives separately. It’s best if you purchase all your drives from the same manufacturer, and you should make sure your disks are RAID compatible as well.
This drive is well-suited for any advanced multimedia storage where large amounts of data are being stored. Unless you work from home, this is probably more than you would need, but it is a great budget choice for a professional setting.
Apple Time Capsule – 2TB
Features
- 2 TB of storage capacity
- Functions as a WiFi stationary
- Only compatible with Apple operating systems
Apple is known for creatively and effectively bridging the gap between all kinds of software and network solutions, and their Time Capsule is no exception. As you might expect from an Apple product, this is more than just a simple network attached storage, as it bridges the gap between several different technologies.
On the one hand, it functions just as you’d expect, acting as a backup data network for your Apple computers and devices. It can also function as a separate external hard drive, able to connect to your Mac through a USB connection.
Finally, it functions as a WiFi station, turning your home into a protected ISP WiFi hotspot with both direct ethernet connectivity and wireless capacity.
At the same time, this Time Capsule does not function exactly the way online cloud storage does, and it does not offer the same array of connectivity that you will find in other network attached storage. This Time Capsule is pretty great for Apple users, but if you don’t have a Mac, you’re out of luck.

Advanced syncing software maintains constant updates between all of your devices. It is compatible with both PC and Mac computers.
Although it contains a self-contained hard drive, the cloud drive can be accessed remotely, regardless if you are in the network or not.In other words, you will still be able to access your music files while sitting in the library so long as you have internet access.
This NAS has a couple of base settings, that I didn’t like, but with a little know-how it’s possible to maneuver around them. This is a budget NAS, after all. The model I checked out was a 2TB drive, but they also sell this item with up to 8 TB of storage.
Unlike some network attached storage, this does include a hard drive, but there is no expansion bay, so once the drive is full, the only solution is ‘to transfer and delete files. With 2 TB of storage, however, this shouldn’t be a problem for a long time.
