SSD vs. HDD: 5 Differences and How to Transfer Data (Feb. 2024)

Ssd Vs Hdd

When it comes to SSD vs. HDD comparisons, most articles focus on the speed at which the storage devices can read or write data. But did you know there are differences in power consumption, lifespan, and other facets?

As with driving a car, hard disk drives (HDDs) are the more established devices, even though they’re slower and tend to break on occasion. Travelers or site owners who opt for air travel or solid-state drives (SSDs) may spend more money upfront, but the gained speed and reliability make the journey plenty worthwhile.

The HostingAdvice team constantly touts the prowess of SSDs, but we decided to dive into the differences between the two storage devices in terms of read/write speed, capacity, power consumption, and durability. Read on for a guide to help you seamlessly switch from HDDs to SSDs, along with our top picks for best hosting plans with SSDs.

Best SSD Hosting Options

As SSD prices drop and capacities increase, more and more hosts are incorporating the storage drives into their infrastructure. The mantras in web hosting are alliteratively amazing and accurate: Speed sells, performance is pivotal, and milliseconds matter. Google has begun penalizing slow sites in search rankings, and one in four visitors will give up on a site if it takes more than four seconds to load.

High-performance SSDs are available at all levels of hosting, but SSD plans do tend to be slightly more expensive and have stricter storage limits than hosting packages powered by HDDs. As with personal computing, however, the benefits are well worth the investment to most users and site owners.

Shared SSD Web Hosting

SSDs gained initial hosting popularity in the more luxurious VPS and dedicated server realms, but we’d argue they make even more of an impact in shared hosting. Notoriously the most sluggish of the three services, shared hosting attracts the most customers.

Aside from first-time site owners who might not understand or even need faster performance, SSDs will provide a critical boost to mom-and-pop small businesses and individual developers looking to stand out from the crowd. Below, we’ve highlighted our favorite choice for SSD-powered shared hosting:

What’s the Difference Between HDD and SSD?

Whether you’re buying a new laptop or shopping for a web server, you’ll want to know how your files will be stored and accessed. Hard disk drives store large amounts of data very cheaply, but the mechanical nature of a spinning disk and read/write head hampers performance and makes the units more susceptible to failure.

Solid-state drives are more expensive but provide a noticeable boost to performance. By storing information on interconnected flash-memory chips, SSDs have no moving parts. The newer technology means that storage capacity of SSDs tends to be lower, but hosting providers often tout how the upgraded hardware can make page loads up to 20 times faster.

5 Comparisons Measuring SSD and HDD Performance

As the price-per-gigabyte chasm between SSDs and HDDs continues to shrink (experts expect the gap will close between 2018 and 2020), more and more people are flocking to SSDs in a variety of uses. In 2014, SSDs powered 21% of all laptops; researchers forecast that number would double by 2017. Conversely, HDD implementation was expected to fall from 79% in 2014 to 59% in 2017.

Hard disk drives (left) typically come in standard sizes, while the appearance of solid-state drives can vary slightly.

With SSD pricing quickly becoming a non-issue, here are five other ways to compare HDDs and SSDs to see which option might be best for you.

1. SSD vs. HDD: Speed

When comparing the two storage drives, the speed at which data is written and read is the distinguishing factor between HDDs and SSDs. The former uses magnetism to store data on a rotating platter; the faster the platter spins determines how quickly information can be stored. SSDs, however, use flash memory and an embedded processor to store data.

SSDs provide noticeable performance upgrades, both for consumer-grade computers and web hosting servers. Many of our favorite hosts that operate all-SSD infrastructure, including InMotion, A2 Hosting, and DreamHost, say the configuration leads to page loads that are up to 20 times faster.

2. SSD vs. HDD: Reliability

Because there are no moving parts, SSDs tend to be more durable and can better withstand the various bumps or jolts your computer experiences. The read/write process doesn’t degrade, and SSDs will maintain data integrity for more than 200 years.

With platters that spin at 7,200 rotations (or more) per minute, the mechanisms inside HDDs are not only subject to more wear and tear, but they are more susceptible to damage if dropped or bumped.

3. SSD vs. HDD: Lifespan

You know the saying, “speed kills.” While that may be a little exaggerated when it comes to storage devices, it does hold a grain of truth. SSD cells can wear out over time, slowly losing performance before dying. According to many, though, SSD users are far more likely to replace their storage drive because of obsoleteness than for suffering from a shorter lifespan.

As for HDDs, the argument is much the same with durability: Moving parts leave more room for things to fail. With only a few nanometers separating the platter and read/write head, any accidental contact can lead to data loss or complete failure.

4. SSD vs. HDD: Power Consumption

This comparison can be illustrated pretty simply. Which takes more energy: running a marathon or tapping buttons on the remote while lying on the couch? HDDs need to spend extra electricity spinning up a stationary platter and moving the read/write head around, while the electricity SSDs use is solely devoted to storing data — no movement, friction, or extraneous noise.

For desktop computers and servers, SSDs equal lower energy bills. On laptops or tablets, users can typically squeeze out a few extra minutes or hours of battery life with SSDs.

5. SSD vs. HDD: Gaming

Resource-intensive computer games provide an excellent test of pushing both storage devices to the limit. However, SSDs make very little difference in gameplay performance. Framerate issues won’t be solved by a storage device; those require an upgraded graphics processing unit, or GPU. Some gamers have reported that SSDs can reduce hitching, or the brief pauses when the games can’t pull assets from the hard drive fast enough to keep up with the player.

Overall, SSDs and HDDs are effectively the same when it comes to the action on the battlefield. The SSD benefits to gamers, however, are the same experienced by other PC users: faster boot times and quicker game loading.

How to Transfer: Migrate or Clone HDD to SSD

Web hosting customers looking to switch to an SSD will have a much easier time of things, as many hosting providers will migrate your websites and domains for free. If you’re feeling brave and feel like tackling the transition yourself, we’ve compiled some information to help you transfer your files and databases to a new host.

Free software, such as EaseUS Todo Backup, can help users upgrade their personal hardware to SSDs.

However, Windows and PC users often struggle with fitting the operating system and personal files onto a smaller-capacity drive when upgrading their desktop or laptop storage. Typically, the easiest way to move an existing Windows installation without reinstalling the operating system is by cloning the drive. With the storage restrictions, though, everything might not fit. Here are the steps to fix that:

  1. When moving to an SSD, you’ll probably need to start by cleaning up your current HDD: Delete files you don’t need, uninstall programs you don’t use, and run the disk cleanup utility to remove any lingering clutter. You might need to offload personal files to an external hard drive, a second internal storage device, or cloud storage.
  2. Once your system is ready to move, you can use a backup and disaster recovery program to clone your information to the SSD. We’re partial to EaseUS Todo Backup, which is a free program that can optimize disk images specifically for SSDs. EaseUS provides instructions for both Windows 8 users and those on Windows 7.
  3. Now that the cloning is complete and you’ve verified that all your files made the move to your SSD, boot your computer from the new drive and reformat the HDD to remove your files. If you had to remove your documents, images, and videos in Step 1, you can restore personal files on the HDD. That way, you can deploy SSD speed for booting up the system and loading applications while still enjoying easy access to your data.

Although balancing the two hard drives can be tricky at first, PC users will certainly benefit from the noticeably upgraded SSD performance and stability. By sharing the work and being properly maintained, both drives stand to last much longer.

Best of Both Worlds? SSD and HDD Combo Hybrids

You’ll have to spend a lot of time reading the fine print to find a web hosting plan with both HDD and SSD storage, but they do exist — particularly at the VPS and dedicated server levels, which allow for much more flexibility when crafting your hosting architecture. For instance, SSDs are great at delivering websites and applications at speed, while the larger capacities of HDDs work well for storing archives and backups.

For personal computing, however, you don’t necessarily have to choose between storage capacity or speed. We’ve already shared how you can create your own hybrid desktop or laptop when upgrading your operating system to an SSD, but hardware vendors have begun manufacturing and selling combination drives, sometimes called SSHDs for solid-state hybrid drives, as individual components or as a feature on a full computer. With computer storage, hard disk drives and solid-state drives are a win-win situation — stronger together than apart.
