3 Best Hard Drive for Security DVR in 2021

The importance of a good hard drive for your security DVR can not be understated. The comfort, peace of mind, and... security... that comes with knowing your hard drive will reliably do its job for years to come is very freeing. There are a lot of options out there, and you might be asking yourself "what is the best hard drive for my security DVR?"

That is why I have put together this list of my top 3.

#1 Seagate SkyHawk Surveillance

The Seagate SkyHawk Surveillance is at the top of my list for a reason. It was specifically designed for use in security systems and is equipped with enhanced ImagePerfect to cut down on those dropped frames. This hard drive offers a 180TB/year workload rating which is 3x the workload rating of most desktop drives, which means it gives you reliable performance in your surveillance system. 

The Seagate SkyHawk has models ranging from 1TB of storage all the way up to 10TB of storage that can hold up to 10,000 hours of HD security footage. 

#2 Seagate BarraCuda

The Seagate BarraCuda is slightly less premium than its sister product, the SkyHawk, but it is certainly no slouch. This hard drive has a similar range of storage capacities as the SkyHawk while offering a better bang for your buck.

The BarraCuda is not specifically made for use in security DVRs so it does not include any of the nifty security specific features that the SkyHawk offers but it does offer similar storage capacity and reliability at a lower price. 

#3 Western Digital Purple Surveillance

Similar to the SkyHawk, in terms of being created for the use in security systems, is the WD Purple Surveillance. With both of them being more premium products, they are also in the same price tier. The WD Purple has a slightly lower disk RPM (i.e slower read/write speeds) than the SkyHawk but it does offer an even larger range of storage sizes with the largest one having a whopping 18TB of storage. This drive also boasts the ability to survive and perform in high temperature environments, so if it will be operating in a place without A/C or poor ventilation it would likely be a good option. 

The best thing about the WD Purple Surveillance is that it comes with a 3 year manufacturer warranty.


Ultimately you can't go wrong with any of these drives. They are three of the best drives on the market and should be able to handle the needs of 95% of people reading this page. If you just want something basic, go with the BarraCuda, if you need something with fast write speeds and smooth frames go with the SkyHawk, and if you need something durable as all-get-out go with the WD Purple. 

Thanks for reading and leave a comment and let me know what drive you ended up going with,
