How We Decided

When researching and testing the best internal hard-drives, we looked at a variety of different models from different brands while reviewing features like performance, ease of installation and overall storage capacity. Most of the drives we picked list a single storage capacity but you can typically purchase them in any size you want.

Overall speed and performance are among the most important features to consider when purchasing, so the drives we included on our list are among the fastest and most reliable internal hard drives you can buy today. When it comes to speed, you can only choose between 5400 RPM (100 MB/s) or 7200 RPM (120 MB/s) on HDDs, and we of course favored drives with higher speeds..

We included both solid-state drives and hard-disk drives on our list, without favoring one over the other. Solid-state drives are typically much faster than HDDs, which is why they’ll always win in the speed department, but they are also more expensive and offer lower capacity on average than HDDs. More important than SSD vs. HDD was the overall build quality and durability of the drives we included on our list. We only included options that are built from high-quality components.

As a final note, we didn’t rate drives with more storage higher since most options come in a variety of different storage capacities based on your needs.

Best Internal Hard-Drive Buyer’s Guide

The Most Important Features to Consider

  1. SSD vs HDD
    The first question you should ask yourself before purchasing a new internal hard-drive for your PC is whether you want a solid-state drive (SSD) or hard-disk drive (HDD). Both hardware components have their own pros and cons, but what you choose can have a huge impact in how your system runs certain applications. If you’re looking for more storage at a better price, HDDs are typically the way to go. HDDs are also typically better for storing larger individual files than SSDs. However, if you’re looking for speed and longer lifespan, SSDs are the way to go.
  2. Speed
    Since HDDs are literally just spinning disks, their speed is measured in RPMs. The higher the RPM, the faster you can expect the HDD to work. The best internal hard-drives will feature a speed of at least 7,200 RPM, while you can expect budget options to perform at 5,400 RPM and premium options to perform at 10,000 RPM or higher. Speed is also measured in megabytes per second of data written to or read from the hard-drive. A 7,200 RPM HDD will typically have a read/write speed of around 150MB/s. The speed of SSDs can also be measured in MB/s, with typical speeds sitting around 550MB/s.
  3. Storage Capacity
    You can’t forget about storage capacity when purchasing a new internal hard-drive. While a good bulk of customers purchase a new hard-drive because their old one went bad, there are just as many customers (if not more) who are simply looking to increase the amount of storage they have on their computer. You can purchase hard-drives in almost any size you want, but be aware that price goes up the more storage capacity you purchase.
  4. Cache
    The amount of cache, or high-speed RAM, that your hard-drive features directly affects the unit’s overall performance. Drives with more cache perform faster than those with less. Most hard-drives feature a 64 MB cache, but you can purchase options with up to 256 MB of cache, if you need the extra buffer.
  5. Interface
    There are a variety of different interfaces, or connection types, that hard-drives use to connect to your PC’s motherboard. While older drives used IDE ports, most modern drives use SATA III for their interface type. SATA III is good for personal usage and if you’re buying a new drive for your home computer, we recommend finding a drive with this interface. You may also see interface types like SCSI or SAS, which are better for enterprise storage options.

Internal Hard-Drive FAQs

What is the most reliable hard drive?

The most reliable hard drive on our list is the SeaGate BarraCuda ST4000DM004. This best-of-class internalSeaGate hard-drive is built with premium components and the brand reliability of one of the biggest names in storage: SeaGate.

What are the fastest internal hard drives?

Solid-state drives are usually the fastest hard drives you can buy today. Since they rely on flash storage technology instead of moving components, SSDs can read and write data much faster than traditional HDDs.

Which internal hard drive is best for PC?

The internal hard drive that’s best for PC based on our testing is the Toshiba HDWE140XZSTA because of its high storage, fast read/write speeds and built-in protection features.

Are hard drives universal?

For the most part, internal hard-drives are compatible with any computer. However, you need to make sure the hard-drive you purchase shares the same interface as your PC’s motherboard. If you buy a unit that doesn’t share a connection type, then it won’t work. SATA is the current standard, so if you purchase a drive with a SATA interface, you’ll likely be alright. You should also consider drive height, especially when buying a drive for a laptop. If you get a drive that’s too big, you’ll need to find something smaller.

Can hard drives be repaired?

Yes, most hard drives can be repaired, but the type of repair depends on the amount of damage done to the drive. In some cases, repair simply means recovering data from the drive. However, you should never try to repair an internal hard-drive yourself unless you have experience with hard-drive repair. It’s incredibly easy to damage your drive even further if you try to fix it yourself. We always recommend taking your PC to a reliable and trustworthy repair shop for hard-drive repairs.

Are hard drives plug and play?

For the most part, internal hard drives are plug and play, as long as you have the correct interface. Once you plug the drive in and turn your computer on, the operating system should detect the new drive and automatically install the appropriate drivers, if necessary.
