When is the next Prime Day?

Although it's technically called "Prime Big Deals Day", the next huge Amazon sale is expected to launch on October 10th and run through the 11th. This 48-hour Prime Day-esque sale will feature deep discounts on a ton of great tech, from phones and smartwatches to laptops and yes, NAS servers. 

Historically, Prime Day has been one of the best times to buy a NAS outside of Black Friday, so make sure you check this page again when the sale goes live, as we'll be collecting all of the biggest deals here. Keep in mind that you'll need to sign up for Prime to gain access to most of the exclusive deals during the shopping event, but there's also a 30-day free trial if you don't want to pay. 

Which NAS should I buy? 

The first question you have to ask yourself is how much storage you're going to need. That sets the basis for whether you should get a two-bay, four-bay, or a larger NAS server.

Synology is the largest manufacturer of NAS servers, and it sells dozens of products across various categories. Synology is known for its high-quality offerings, and its products are built to last. But the defining feature of Synology's NAS models is the software, with the web-based DiskStation Manager setting the standard for this category.

If this is the first time you're buying a NAS and you don't want to invest a lot of money into an enclosure, the Synology DiskStation DS220j is our top pick for the best cheap NAS. You're still getting all the best software features that Synology has to offer, and while you don't get as many drive bays as some devices, it is a great choice for those making their foray into this segment. If you don't mind spending a little extra cash, the Synology DiskStation DS723+ is an excellent choice for most people. 

How do I choose a hard drive for my NAS? 

Choosing the right hard drive for your NAS is just as vital as selecting the right enclosure. Because NAS enclosures are designed to run 24/7, there are NAS-focused hard drives available in the market. These models feature vibration resistance and are designed to handle the stresses of a 24/7 environment, and differ from your regular hard drives.

Another factor to consider when choosing a NAS hard drive is the speed. HDDs are usually available in either 5400rpm or 7200rpm, and the latter delivers better performance because the spindle moves at 7,200 rounds per minute. I've used 5400rpm drives in NAS enclosures tailored for media streaming for years without any issues, but if you're building a more enthusiast-focused NAS and are looking for better performance, pick a model with a 7200rpm. 

There are several NAS-focused hard drive product lines, with WD Red Plus and Seagate IronWolf dominating the sales charts. With drives starting out at 1TB and going all the way to 20TB, there's no shortage of options available across either product line.
