The Best & Fastest Internal Hard Disk Drive (HDD) | 2015


best hard driveThere’s a consensus among IT professionals that the main culprit for the slowness modern computers undergo is the primary storage device, represented often by a mechanical hard drive. As a computer technician myself, I’ve found that most of the sufferings computer users experience come from their slow hard drive, and seeking the fastest internal hard drive as a replacement for your current drive is a very wise step to take. Because usually there is not complaints against processor speed, and the graphics card performance is impressive, and the only thing that gets on nerves is the slow responsiveness of the computer systems, especially when you try to store/transfer huge files, load resource-demanding games, launch heavy applications, or even to just try to bootup a machine with an operating system stuffed with many applications. These all justify finding a speedy solution to cut down on the time wasted in waiting.

Why To Go For The Fastest Internal Hard Drive

I have written this article assuming that you are already aware of the existence of the flash-based solid state drive (SSD), which is undoubtedly a much faster and a more reliable solution than any spinning platter-based hard drive out there. [Check out our fastest SSD list] Yes, there are still strong and valid reasons for picking up a traditional hard drive instead of an SSD, but I have been always recommending obtaining them both in a combination where the SSD takes care of the operating system and user’s favorite files and applications, while the hard drive is dedicated to backup and file transfer and storage. [Read if you wish: “The Best To Do: Get an SSD and Keep Your HDD“]. That’s if you want to build a new rig and can afford the expenses of both, otherwise you can still find in premium hard drives what meets most of your requirements.

That being said, obtaining the fastest internal hard drive can be a good idea if your budget is limited and you only want a single drive for your machine for all purposes.

Our recommendations

There are many hard drive brands in the market, and without testing each of them you cannot distinguish the good from the bad. To be honest, I have only tested Western Digital Raptor 160GB SATA/300 10,000RPM 16MB Hard Drive and I can say without doubt it is the best hard drive in terms of speed, price and reliability you can get for your SATA-II computer. It runs at 10k spindle speed, with 160 GB capacity, and for what? for just $30 [At the time I bought it. Just note that this drive is so on-demand, and there is literally a HUGE SALE on it. So the more time passes the higher the price becomes], can you imagine? I have placed this hard drive in the “fastest SATA-II hard drive for older computers” section below.

As for the rest of drives listed below, I relied primarily on the IT professionals’ reviews, like Tom’s Hardware, Anand Tech, StorageReview, and others. I also benefited from the many users’ experiences stated in their reviews on for the particular products, and therefore I have made this unique list that gathers the best & fastest traditional hard drives in one place.

The drives listed below are deemed the best and fastest SATA III hard drives of today. We will keep updating this list whenever necessary.
