Different Types of hard drive: SATA vs. SSD vs. NVMe

When you talk about pc storage, you’re talking about hard drives. These devices are wherever all the information on your computer exists, from the package files that govern your device to the necessary work document that you just absolutely can’t lose to the sport you begin up at the tip of the day to relax. All of those are keep on your onerous drive, therefore you would like to create positive that you get the proper kind of hard drive for no matter you’re making an attempt to do. There are three completely different kinds of hard drives: SATA, SSD and NVMe. During this article, you’ll find out about every kind and what their strengths and weaknesses are. Whether or not you’re considering shopping for or building a replacement pc or upgrading your current one, this could help you select one over the others.

What is a hard drive, and why do I need it?

The hard drive is that the part that stores your data. You’ll typically see the term “hard drive” abbreviated to “HDD.” There are many reasons you may want to buy one: you’re out of house on your current HDD and want a much bigger one you’re noticing that it takes a protracted time to open documents or export giant files like videos you’re building a replacement pc from scratch regardless of the situation, understanding why you would like or need a new drive can help you know what you want and need. Once you’ve got that patterned out, it’s time to understand more about the various sorts of hard drives and therefore the trade-offs between them.

SATA drives

Introduced in 2003, SATA (or Serial Advanced Technology Attachment) is that the default interface for many desktop and laptop hard drives. They’re spoken as SATA hard drives, however they are truly rotary hard drives with spinning platters and a moving needle that writes knowledge to consecutive sectors on every platter. SATA hard drives are incredibly quick compared to their predecessor, the PATA hard drive, and might write to the disk with an interface rate of half dozen Gb/s with a turnout of 600 MB/s. a single drive can vary from 500 GB to 16 TB and are available at a lower value than any of the opposite drive sorts mentioned here. They’re good drives if you would like a great deal of low cost storage and don’t need extraordinarily high reads or writes. Since knowledge is physically written to a disk, it also can become fragmented, which means that completely different sectors may be spread across different areas of the disk, deceleration down the drive. They are also liable to shock and abrupt movement since there are moving components in every drive, that makes them a poor choice for laptops

SSD hard drives

SSD stands for Solid State Drive. These disks don’t have any moving parts. Instead, all of the information is stored on non-volatile flash memory. Meaning that there isn’t a needle that needs to move to scan or write data which they’re considerably faster than SATA drives. It’ difficult to seek out a certain speed as a result of it varies by manufacturer and type factor, however even the lower-performing drives are akin to SATA drives. The drawback is that these drives are significantly dearer and don’t are available in as several sizes. SSD drives vary from concerning 120 GB to a pair of TB, and are concerning 2-4 times the price of a SATA hard drive of an equivalent size. Since there are not any moving parts, these drives also are tons a lot of durable, and there are type factors built specifically for laptops, creating them ideal for storage on the go.


Released in 2013, Non-Volatile Memory categorical, or NVMe, may be a form of SSD that’ connected to a PCI Express (PCIe) slot on a main board. These slots were originally designed for graphics cards, in order that they are implausibly quick. Speeds on NVMe drives can reach an interface rate of 32 Gb/s with a turnout of 3.9 GB/s. that may be terribly helpful if you’re doing one thing that wants loads of disk throughput, like diversion or high-resolution video editing. For as fast because it is, there are some drawbacks to NVMes. For starters, they’re solely out there on desktop PCs and are very expensive. Also, whereas they will be used as secondary drives, to use it to its full potential, you’ll need to put in your operating system on it. Most BIOS don’t support booting from NVMe at this time. It’ still potential to induce one that does, however it’d mean exchange your entire main board.

When to choose SATA, SSD or NVMe

There are loads of issues once deciding between different components. You’ve got to decide on what works your technical, capability and budget requirements. Below are some guidelines which will help, and whereas they won’t fit each situation, you will realize them helpful when coming up with your next pc build.

You may want to consider a SATA drive if you:

  • Need a large quantity of storage
  • Are on a good budget
  • Want a general purpose hard disk

You might want to consider an SSD drive if you:

  • Are upgrading a laptop
  • Want quick storage under 2TB

You might be better served by an NVMe drive if you:

  • Are building a high-end workstation or gaming pc
  • Don’t have a budget constraint
  • Are building a server that’s about to host a storage-intensive application

It’ also price mentioning that you’re not restricted to buying only one hard drive; PCs will generally support many at a time. And whether or not you get the performance you wish from it’ll rely on wherever you save files. For example, a common configuration for PCs that render video is to use a quicker drive like an SSD or NVMe to run video rendering software (Camtasia, Adobe Premier, etc.) then transfer the finished product to a cheaper, larger SATA drive.

Continue building your knowledge and skills

Now that you’ve had a crash course on the common styles of hard drives and their features, you ought to feel assured creating an informed decision. Take an honest look at the explanations behind exchange your drive, the quantity of space you would like and the way abundant you’ll be able to spend. By doing that and applying what you’ve learned here, your arduous drive buying expertise are going to be much easier.
