Analysts say the NAS market is on an upward trajectory, with businesses, in particular, asking for scalable solutions to ever-growing data storage needs.
Western Digital’s stock rose amid investor interest in AI.
Synology launched new all-flash storage solutions for the enterprise market.

It depends on how much data you have to store, how much access you want to it, and how precious that data is to you.

External drives are great for a few gigabytes of data, but if your needs are closer to terabytes, or you have data that needs to be accessible across multiple systems, or you want to protect your data from loss or corruption, this is where a NAS comes into its own.

Well, on the face of it, yes, but once you dig deeper, not really. NAS units need a network to connect to , ao unless you have this in place, a NAS isn’t going to be suitable.

Also, USB external drives are very much a plug-in-and-go experience, while NAS units require a fair bit of setup and some technical expertise (networking and RAID considerations) to get going.

You can repurpose an old PC or even build a very custom NAS solution to meet your exact needs.

ZDNET author and resident hardware expert David Gewirtz has built his own NAS boxes for years, including some that were highly customized. But as the NAS offerings from vendors like Synology, QNAP, and Drobo improved, the need to build his own diminished.

If you’re comfortable with the prospect of sourcing PC parts and building PCs, you’ll probably want to go it on your own. But if you’re new to PC building, buying an appliance NAS is probably the way to go.

RAID, which stands for Redundant Array of Independent Disks, is a data storage technology that combines multiple physical disk drives into a single logical unit for improved performance, redundancy, or both. The primary purpose of RAID is to enhance data protection and improve storage efficiency by distributing data across several disks in various configurations known as RAID levels.

Here’s a breakdown of three of the most common RAID levels:

RAID 0 (Striping)

RAID 0 splits, or stripes, data evenly across two or more disks. This configuration offers improved performance because multiple disks can be read or written simultaneously. However, be aware that this provides no redundancy. If one disk fails, all data in the array is lost.

RAID 1 (Mirroring)

RAID 1 duplicates, or mirrors, data across two or more disks. This setup offers high data redundancy because each disk in the array contains an exact copy of the data. If one disk fails, the data can be recovered from the other disk(s). However, note that RAID 1 does not improve performance and effectively reduces usable storage capacity by half.

RAID 5 (Striping with Parity)

RAID 5 combines striping with parity, distributing data and parity information across three or more disks. Parity provides fault tolerance, allowing the array to withstand the failure of a single disk without data loss. RAID 5 offers a good balance of performance, redundancy, and storage efficiency.

The primary difference between Network Attached Storage (NAS) and Direct Attached Storage (DAS) lies in how they are connected to and accessed by devices in a network.

NAS devices connect to a network, typically through Ethernet, providing storage that can be accessed by multiple devices on that network. This setup allows multiple users and devices to access and share data simultaneously over the network, making NAS ideal for collaborative environments. NAS units often come with their own operating systems and can support a variety of applications, including file sharing, media streaming, and even server functions like web hosting. These devices are managed via a web-based interface, allowing for remote administration and configuration. Additionally, NAS solutions are generally more scalable, allowing for easy expansion by adding more drives or connecting additional NAS units to the network.

In contrast, DAS devices connect directly to a computer via USB, Thunderbolt, or another direct interface, making them accessible only to that specific computer. DAS systems are typically single-user devices, meaning only the connected computer can access the stored data. For other devices to access this data, it must be shared through the computer to which the DAS is connected. DAS units are simpler and usually do not come with their own operating systems or support for additional applications beyond basic storage. These devices are managed directly through the operating system of the connected computer, without the need for web-based interfaces. Because they connect directly to a computer, DAS devices can offer faster data transfer rates compared to NAS, which relies on network speeds.

The choice between NAS and DAS depends on specific requirements for accessibility, scalability, and performance. NAS is best suited for environments where multiple devices need to access and share data, such as in homes with multiple users, small businesses, or professional settings requiring collaborative access to large files. On the other hand, DAS is ideal for single-user scenarios where fast data transfer rates are critical, such as video editing, graphic design, or personal data storage needs.

Vendors typically estimate the lifespan of a NAS device to be between three to five years. However, it’s possible for a NAS to exceed this range, potentially lasting up to a decade. Despite this, the risk of failure escalates over time.

Be on the lookout for signs of hardware deterioration, like sluggish performance and connectivity problems, which may indicate impending failure.

You can potentially improve a NAS device’s lifespan by allowing it to hibernate while not in use. For example, if you are away from home for several months, you may want to consider giving it a rest. However, NAS devices can be left on permanently, as many NAS devices have been specifically built to allow this.

The costs of setting up a NAS system can quickly spiral, but that depends on how many drives you intend to use. For a single drive setup, it might only be a few hundred dollars. As you need more bays and if performance is a priority, you may end up spending thousands of dollars.
