How Will You Use Your HDD?

Manufacturers build hard drive models for different use cases. In general, there are five categories: consumer, NAS (network-attached storage), archiving/video recording, enterprise, and more recently, data center. a consumer drive may spin slower to save energy and provides little if any access to tools that can adjust the firmware settings on the drive. An enterprise-class drive, on the other hand, is typically much faster and provides the user with access to the features they can tweak to adjust performance and/or power usage. So, it is essential to look for drives as per your needs.

Cost vs Quality

Most lower-priced hard drives do not offer the exclusive features of its upgraded versions. If you are seeking improved reliability, longer warranty period, and faster performance, you might be better off purchasing the enterprise version of a drive.

Recording Technology

There are different types of recording technology which each have their trade-offs. The most common type of recording technology is Perpendicular Magnetic Recording (PMR), which writes and reads data from circular tracks on a spinning platter. There is another technology named Shingled Magnetic Recording (SMR), which overlaps recording tracks to store data at a lower cost. This means that SMR drives can cost less than their PMR counterparts, but will experience more write delays and lower peak average performance.

Storage Capacity

When it comes to capacity, it is generally better to get a bigger drive than necessary, as long as you don’t compromise performance and reliability. HDDs come in a wide range of capacities, capping out at 16TB per drive due to physical limitations.

Transfer Speed

The performance of a HDD is measured by many factors, but RPM [Revolution per Minute] is an important one. Higher RPM means the faster transfer of data to and from the drive. You can ignore the SATA speed, which describes the theoretical maximum speed of a SATA connection. But a 7200 RPM drive will certainly be faster than a 5400 RPM drive.
