Please stop putting desktop hard drives in your NAS


Are you ready to buy your first NAS? Before you click purchase, there’s one major thing you need to think of first—do you have the right hard drives for a NAS? Not all hard drives are created equal, and you need to make sure your NAS has storage that’s up to the task.

Wait, aren’t all hard drives created equal?

You might think a hard drive is a hard drive, right? You’re mostly right, but also somewhat wrong. While all hard drives work as hard drives, they’re not all designed to work in every application.

Let’s take one of the most well-known desktop hard drives as an example, with the WD Blue. Western Digital’s Blue hard drive comes in multiple speeds and a handful of sizes. The problem is, this drive is designed for use in a desktop, not a NAS.

Hard drives designed for desktops are built with normal desktop usage in mind—being on most of the day, light-duty data transfers, and relatively decent airflow and temperature regulation. Chances are, you’re not going to be moving tens or hundreds of terabytes of data per day (or even year) with a normal desktop, and drives like the WD Blue are built with that in mind.

However, drives like the WD Red are designed differently. With enumerated workload ratings, hard drive manufacturers let you know how much work you can expect a NAS HDD to stand up to per year. On top of that, NAS-focused drives also typically have better quality parts, longer warranties, and special firmware designed for RAID usage. Conversely, desktop drives often use Shingled Magnetic Recording (SMR) technology, which can crash a RAID rebuild.

There are also specialty drives, like the WD Purple, which are built for 24×7 video surveillance. While a NAS might have times of heavy reads and writes, video surveillance systems are writing all day, every day, nonstop.

Curious what “Surveillance” and “NAS” hard drives are? Do you need one? Let’s find out!

Most non-NAS HDD warranties don’t cover being used in a NAS

Not only will your HDD die faster, but you won’t get to cash in on the warranty

Your hard drive comes with a warranty when you purchase it. These warranties are designed to cover manufacturer defects and early breakdowns of the drive within the coverage period.

Drives like the WD Blue are covered for two years, while the WD Red Plus is covered for three years and the WD Red Pro is covered for five years. The coverage length isn’t the only difference, however. Since Western Digital (and other hard drive manufacturers) are expecting you to use desktop hard drives in desktops, there’s a chance that they could deny warranty coverage if it’s discovered you’re using the drive in a NAS.

Why would a company deny coverage if you use the drive in a NAS? Well, network attached storage servers put a much heavier workload on a drive than a desktop. Since desktop-class hard drives are only designed for a desktop workload, putting them under the extra stress of a NAS could fall under “improper use” or “misuse,” though it will be up to the manufacturer to decide that.

NAS HDDs are designed to withstand 24/7/365 runtimes

In other words, they last a long time

Since a NAS hard drive is built specifically for use in a NAS, they’re designed to take much more abuse.

While desktop hard drives aren’t given any type of workload or endurance rating, the WD Red Plus has a defined 180TB/year endurance rating. The higher-end WD Red Pro is rated for a massive 550TB/year workload. These workload ratings are designed to give you an idea of how much data the drive can withstand moving in a given time (how many terabytes of data transfer per year).

Not only are NAS-designed hard drives built for high-endurance applications, they’re also built to withstand the harsher environment of a NAS. While you might only have two or four drives in your NAS, hard drive manufacturers build these drives to withstand hotter temperatures and much more vibration than a traditional hard drive. For example, my NAS is actually a retired rack-mount server with 12 drive bays—and temperatures can definitely get toasty in it in the summer.

NAS hard drives are also designed to be powered on and used 24 hours a day, 7 days a week, 365 days a year. My NAS right now has an uptime of three months since its last reboot, but, at my peak, I had an uptime of over a year without ever rebooting or powering down. Having a drive constantly on all day, every day, for many days in a row is pretty taxing on the platters and other hardware.

Add to that how often these drives are accessed (I run a media server, homelab services, photo backup server, and much more on my NAS), and you have a recipe for hard drive abuse—and your drive better be rated for it if you want any type of solid uptime.

So, if you’re looking to purchase a NAS, make sure your hard drives are rated for the task at hand. Do your research ahead of time, and you’ll thank yourself later.

The WD Red Plus hard drive line is designed specifically for NAS usage. This means the drive is build to withstand 24/7/365 usage, with up to a 180 TB per year workload rate. You’ll also get a 3-year warranty with the purchase of WD’s Red Plus drive lineup.



Invest in good HDDs, you won’t regret it

If you’re not quite ready to drop brand-new hard drive money for your NAS builds, don’t panic. There are ways to save some cash while building out your storage server. I’m personally a big fan of recertified hard drives. Almost all the drives in my NAS are recertified or refurbished, and I’ll continue to go that route to save money on storage upgrades.

Also, don’t think you have to buy a brand-new NAS, either. As I mentioned, I bought an old rack-mount server to use as my NAS, but there are plenty of other devices that you can build a NAS with. Whether shopping new or looking on the used market, here’s everything that you’ll need to build your own NAS.

macOS has a built-in screenshot tool that gets the basics right. You can take a screenshot, record your screen, and even annotate your captures. But the moment you want something more, like scrolling capture, advanced annotation tools, or a quick way to share your screenshots via a link, it starts to fall apart.

That’s where CleanShot X comes in. It’s a powerful screenshot and screen recording app for Mac that replaces the built-in screenshot tool. It feels as if the developers looked at the screenshot features in macOS and added everything that was missing.

Over the past few years, the app has added several new features I didn’t know I needed until it offered them. It has become one of my favorite Mac utilities, and in this article, I will show you its features that will convince you to buy the app instantly. 

Scrolling capture saves you from stitching screenshots together

One of the most frustrating limitations of macOS’s screenshot tool is that it can only capture what’s visible on your screen. If I need to capture a long webpage or a full chat history, I am stuck taking multiple screenshots and stitching them together. That wastes an unbelievable amount of time. 

CleanShot X solves this with its scrolling capture feature. I can trigger the scrolling capture, and CleanShot X automatically scrolls through the content and delivers a single image. I don’t even have to manually scroll the page if I don’t want to.

This feature alone saves me hours of time every month. If you have to deal with long screenshots, you should definitely try it out. 

Time delay capture lets you screenshot the impossible

Some screenshots are tricky to take because they require you to trigger something before capturing. For example, sometimes the on-screen feature you want to capture disappears as soon as you use a keyboard shortcut or click anywhere with your mouse. 

Sometimes, the on-screen elements appear for a short time, and by the time you hit the screenshot shortcut, they disappear. CleanShot X’s time delay capture gives me a few seconds to set things up before the screenshot is taken. I trigger the capture, put everything in place, and CleanShot X does the rest. 

It’s a small feature that solves a genuinely annoying problem.

Capture text from images with OCR

I love that CleanShot X has a built-in OCR function. It lets me capture text directly from any image or video on my screen. Although it happens rarely, I have come across websites that don’t let me copy content. With CleanShot X’s OCR function, that’s not an issue. 

I use this constantly when reviewing PDF documents with restricted permissions or watching a video on YouTube. It is far faster than typing things out manually, and it works surprisingly well. There are many apps that let you capture text with OCR, but since CleanShot X has this feature built in, I don’t need to install an extra app. 

Add beautiful backgrounds to your screenshots

If you share screenshots for work, tutorials, or social media, you know how plain a raw screenshot looks. CleanShot X lets me add beautiful backgrounds to my screenshots, turning a flat capture into something that looks polished and share-ready.

For backgrounds, I can choose from solid colors, gradients, or even my current desktop wallpaper. I can also adjust the padding and shadow, align the screenshot to the edges, and adjust the corner radius. It takes a few seconds and makes a huge difference in how professional your screenshots look.

Annotation tools that get the job done

While macOS’s screenshot tool lets you annotate your screenshots, the annotation tools inside CleanShot X are, in my opinion, the best available on the Mac. 

I can add arrows, text labels, shapes, highlights, and more. I can also change the weight and color of annotations. There are also multiple arrow styles I can choose from. I especially like the curved arrow style that lets me curve the arrows and make them pop. 

One of my favorite new additions is the “Highlighter” tool. It snaps to the text in a screenshot, which makes it really easy to highlight it before sharing. 

Then there’s the “Spotlight” tool that highlights your selection by darkening the rest of the screenshot. It’s perfect for drawing someone’s attention to a specific part of a screenshot. 

No matter what annotation tools you need, you can find them and more in CleanShot X. 

Hide sensitive information before you share

You can find hundreds of instances in the news where a prominent figure shared a screenshot and inadvertently revealed private information. Thankfully, CleanShot X has a dedicated tool to blur or black out sensitive information, so such accidents never happen.

I can choose to pixelate, blur, or completely black out the information. The best part is that I can also adjust the strength of these effects. It lets me blend in the hidden information so the blur doesn’t stand out from the rest of the screenshot. 

Video and GIF recording built right in

CleanShot X also lets you record your screen as a video or export directly as an optimized GIF. The GIF export is particularly useful for sharing quick demos or showing someone how to do something without creating a large video file. 

It can record the entire screen, a specific window, or a custom region. It can also show my mouse clicks and keyboard shortcuts. I can record my computer audio, my microphone, and webcam video. 

I love that it automatically adds the webcam video in the corner, so it doesn’t interfere with the rest of the recording. I can also change the video size and shape. All these features make it really easy to create video tutorials. 

Quick share with cloud links

Once you take a screenshot or finish a recording, you need to share it. Of course, you can easily share screenshots via messages or emails. But CleanShot X gives me a better way. 

Whenever I capture something, it opens a quick share overlay. I can use it to instantly upload my screenshots to CleanShot Cloud and grab a shareable link with a single click.

I no longer have to drag files into cloud storage, attach images to emails, or upload to third-party services. I capture it, click share, and paste the link. It is one of those workflow improvements that sounds minor until you use it every single day.

Capture beautiful screenshots with CleanShot X

CleanShot X has become one of my most dependable apps on Mac. In fact, all the screenshots you see in this article or any of my articles have been captured using CleanShot X. Yes, it’s a paid app, but it has paid its cost multiple times over with the time it has saved me. 

CleanShot X is available as a one-time purchase or through a SetApp subscription. If you want unlimited cloud storage, you have to pay for a monthly subscription. That will also get you advanced features like a custom domain and branding, password-protected link sharing, and more. 

For most users, the one-time purchase is more than enough, and it’s what I use. If you spend any time taking screenshots or recording your screen on a Mac, it is absolutely worth every penny.
