10000 Rpm HDD vs SSD – Comparison

For many years, computers have been slowed down by their storage. As RAM is fast memory and processors have been getting better, storage was always left behind.

RAM stepped up to help with this as it was faster to access data from it than reading from a slow disk each time the processor needed a resource.

All that changed when storage started getting much better in terms of speed and latency, to be more specific.

And, concerning an increase in speed, hard drives and SSDs were created and improved upon for the users’ sake.

Let’s take a closer look at 10000 rpm HDD vs SSD. What are they and how do they compare?

A 10,000 Rpm HDD has a spinning platter that does 10000 full 360-degree rotation every single minute. On the other hand, an SSD uses chips with memory cells.

SSDs have been around for quite a while but they have always been too expensive. That changed over the last decade and fortunately we now have access to some fast SSDs for only a fraction of the cost that they once were.

SSDs have proven to be a great way to store non-volatile information on computers. They have many advantages that stem from how they are implemented in the exact way they work.

SSDs make use of flash cells to store the single bits of data, either a 0 or a 1, as the bits are represented in binary notation.

Data can be accessed faster on SSDs because there are no moving parts and there’s no seeking arm that needs to wait for a platter to move before it can get to a particular memory segment.

When they first joined the mainstream market in personal computers, solid-state drives carried a hefty price tag, but this has reduced significantly and you can now pick a basic SATA SSD at an affordable price and improve the performance of your computer.

The 10000 RPM HDD

RPM or Revolutions per minute is a unit that describes the speed at which the spindle of a hard drive rotates and moves the platter.

The most common hard drives that come in laptops and some desktops are usually 5400 or 7200 rpm drives. However, some enterprise drives can hit up to 15000 RPMs

We know that hard drives operate by causing a metallic disk called a platter to rotate around a spindle while an arm moves across it to segments where particular data is stored.

With a 10000 rpm drive, access to data is pretty fast because you have to wait for much less time to get to a particular segment and sector than you would in a slower drive.

As a result, a 10000 rpm drive is quite fast at both read and write speeds and costs a little more than conventional HDDs.

Now that we have a basic understanding of both storage devices, let’s get to seeing exactly how well each performs compared to the other.

We’ll look at some common metrics that are used to compare hard drives and SSDs to get a clearer picture of this.

Energy Usage

When it comes to hard drives, an important point to note is that higher RPMs results in more energy consumption.

The motor in the hard drive uses a lot more energy to rotate the disks at the high speeds it moves at and while this can be negligible with a single hard drive, in large data centers, this can be a potential cause of some significant energy usage, and bills!

SSDs, on the other hand, don’t use moving parts and their data can be read electrically. They use significantly lower energy and hence over time, buying an affordable SSD can have energy savings that warrant their slightly higher prices.

Storage Capacity

The faster a hard drive spins, the less the maximum capacity it can have. There’s a good deal of physics behind this but the simple version is that it has to do with the fact that at high spinning velocities, the platters encounter a lot of air resistance.

This can cause some problems with reading speeds and can even make the drive unstable for use. So, to counter this, the platter needs to be made smaller.

Now, we already know that the information gets written onto the platter. So, a smaller platter means a smaller area on which data can be written to, hence, smaller disk capacities.

Hence, 10000 RPM hard drives are generally found in 500 GB and 1 TB capacities. SSD, on the other hand, can be found ranging from 256 GB all the way to 4 TB for common users.

Performance

A 10000 RPM hard drive is considerably slower than even the SATA SSD.

On top of that, due to the high revolutions it does, the drive ends up generating a lot of heat if not properly ventilated. For this reason, some of the drives come with a heat sink that helps dissipate the excess thermal energy.

The heat sink helps maintain optimum performance by cooling the drive if it gets too hot.

An SSD, on the other hand, doesn’t generate much heat during regular usage and it will also run more quietly compared to a 10000 rpm HDD which will generate some noise.

A Western Digital Velociraptor 10000 RPM SSD displays performance that in some metrics comes close to that of some SATA SSDs.

Here is a speed comparison

  • 7200 RPM HDD – 800 Mb/s
  • 10,000 RPM HDD – 1.6 Gb/s
  • SATA SSD – approx 4.8 Gb/s

So Why Go For a 10,000 RPM HDD?

They aren’t cheap, and they aren’t as fast. These hard drives had an edge for enterprises when SSDs were still in their infancy. They have lost their charm as even databases are moving more toward SSD as compared to HDD. [1][2]

Cost

In a storage amount comparison, a 10000 RPM HDD comes close to a SATA SSD in terms of the purchase price.

Furthermore, it uses a lot of power. So, that can be added to the overall cost too.

However, as mentioned, the power can be a little negligible at times unless you are running more than a few of them for long periods.

If you are looking for a reasonably priced storage device with fast speeds then you will be better off if you went with an SSD instead of the 10000 RPM Hard Drive.

Considering that they are almost priced the same, some of the features and capabilities of the SSD that the 10,000 HDD lack should seem appealing.

For one, with an SSD, you have reduced points of failure because the drive doesn’t have any moving parts.

Additionally, an SSD has tolerances against magnetism, the same cannot be said for an HDD because it relies on magnetism to store data, and a little exposure can cause disk errors.

Other factors like low power requirements and less noise generated are also a plus point for SSD.

Conclusion

A 10000 RPM HDD is a high-performance drive that is used for mass storage in enterprise level solutions like data centers.

They are significantly faster than conventional hard drives like the 5400 RPM and 7200 RPM since they have better latency during data reads.

However, compared to SSDs, they still fall a short significantly because even some Lower-end NAND SATA SSDs still give them a huge run for their money, let alone the PCIe NVME SSDs.

Despite this, the hard drives still cost almost as much as some SSDs. So, given the choice, 10000 RPM HDD vs SSD, it may be prudent to go for the SSDs for personal use.
