Flash and solid-state drives have been around for a while, and they’re constantly evolving. In this article, we’ll take a look at some of these developments and explain what they mean for your hard drive, computer, or other devices.

Moving parts

The first major difference between HDDs and SSDs is how they store data. HDDs have mechanical parts, which makes them less reliable than SSDs. An HDD’s head moves across a disk to read and write data, but that moving head can get stuck or produce errors in some circumstances. The magnetic platter inside an HDD also has moving parts that can fail after a while.


On the other hand, SSDs don’t use any mechanical parts at all—all they need to function properly is power from a computer’s USB port (or SATA cable). This makes them more stable than HDDs over time because there are no moving parts that could cause physical damage as well as degradation of performance due to wear and tear over time.

SMR (Shingled Magnetic Recording)

SMR (Shingled Magnetic Recording) is a type of recording technology used in hard drives. It’s a method of writing data to a disk that involves overlapping the tracks, which allows more data to be written on each track.

This is because SMR increases the density of data tracks and therefore increases the storage capacity of HDDs by allowing for more information to be stored on each inch or square inch of the drive’s platter surface area.

Solid State Hybrid Drives

Solid State Hybrid Drives (SSHDs) are a combination of both HDD and SSD that may increase the performance of your computer. They have a small amount of NAND flash memory, which allows them to read and write data faster than an HDD. However, they have a large spinning disk inside that stores most of your files and programs, so you can still access them quickly when necessary. Whereas, most of the prebuilt gaming PCs under 2000 are using SSDs like we see some of them on PC253.

SSDs are made from solid-state chips

SSDs are made from solid-state chips, while HDDs use spinning platters. These differences mean that an SSD is much less likely to fail than an HDD and it also performs better.

SSD vs HDD: Which One Is Better?

The days of moving parts are long over. You can get an SSD or HDD to do almost anything you need, but each has its own strengths and weaknesses. If you’re looking for a way to improve your computer’s performance then there’s no question about which one will be best for you!

HDDs have slower read/write speeds than SSDs

If you’re looking for speed, then an SSD is the way to go. An HDD has a slow seek time, rotational speed, latency, and bandwidth. This means it’ll take longer for your computer to find the file you need to open or save. If you have multiple files open at once, this can be even more frustrating because your computer won’t be able to keep up with all the requests coming in at once. If you enjoy watching videos online or streaming video games live over Twitch—an online platform where gamers can stream their gameplay while they play—then an SSD is also faster than HDDs because of its higher random access time and sequential access time speeds

HDDs are affected by physical shock and vibration more than SSDs

The biggest difference between HDDs and SSDs is their physical design. HDDs are built much like traditional hard drives, with a spindle that spins around at high speeds while an arm reads and writes data to the platter. This means they’re more susceptible to shock and vibration than SSDs, which are generally more stable because they don’t rely on moving parts.

That’s not to say you can drop an HDD without it breaking—it just means that if you do drop an HDD, there’s a greater chance of it failing than if you were using an SSD instead. And while magnets aren’t likely to affect your SSD in any way (as long as they’re not extremely powerful), they could cause a catastrophic failure in your HDD if used incorrectly. Magnetic interference can even cause problems for other electronic devices such as speakers or monitors; so keep all of these things in mind when deciding whether or not which type would be best for whatever application needs one!

SSDs are not affected by magnetic fields and are therefore less likely to lose data if near magnets or exposed to magnetic fields.

While HDDs use moving parts and magnetic fields to operate, SSDs do not have a read/write head, nor do they use magnetic storage. Instead, SSDs are made from solid-state chips that store data in binary code. Because of this difference, an exposed magnet can destroy your HDD (and all the data it contains) instantly. On the other hand, if you’re holding a magnet near an SSD—even at close range—there’s no way you’ll be able to tell if there’s any damage done until it fails months later or even years later!

The reason why magnets have such devastating effects on HDDs is that they disrupt the delicate alignment of atoms in the memory cells on the platters inside hard drives. When these particles become disoriented or out-of-place like this, they simply don’t work anymore!

HDD uses a different method for writing data to the disk

You may have noticed that when you save a file on your computer, it tends to write data in a continuous spiral. That’s because hard disk drives (HDDs) use a different method for writing data to their disks than SSDs do.

  • In an HDD, the magnetic oxide layer is coated with ferromagnetic material—it’s this combination of iron oxide and ferromagnetism that allows the head to be attracted by it and read data from it.
  • On top of this layer is another thin protective film called an overcoat or lubricant that prevents both forces from damaging data as they’re written onto the platter/disk.

SSDs do not have a dedicated read/write head

The first thing to know about SSDs is that they are much different from HDDs. Flash memory chips are used in an SSD, while magnetic disks are used in an HDD.

  • A flash memory chip does not have any moving parts, so it can store data even if there’s no power (e.g., when you turn off your laptop). You might think of this as the difference between a pen and a pencil: The former requires batteries or another source of power to function, while the latter doesn’t need anything other than what’s already present in your hand.
  • Magnetic disks use spinning platters and read/write heads that move across them to read information; they use more energy than flash-based storage devices because they have moving parts.

Know the difference between HDD and SDD

Let’s start with a basic explanation of how each device works. HDD stands for “hard disk drive,” while SSD stands for “solid-state drive.” A hard disk drive is a magnetic disk drive that has moving parts in it. This means that you can use your computer to access files and data on the hard drive easily. On the other hand, an SSD does not have any moving parts at all—it stores data digitally instead of magnetically as HDDs do.

In addition to having different physical structures, HDD and SSD also differ in speed and reliability:

  • In general, HDDs are slower than SDDs because they have spinning disks inside them that must rotate to read data from them; this happens hundreds of times per second! On the other hand, an SSD only needs ohms (electrical current) or nanoseconds (1 billionth of a second) to read data from its memory chips onto its circuits—so much faster!
  • Because there are no moving parts inside an SDD, it can withstand more shocks than an HDD without any damage whatsoever; this makes them ideal in situations where there might be vibrations such as those caused by heavy machinery or vehicles driving nearby using machinery outdoors during work hours!


You should now have a better understanding of how SSDs and HDDs work. You also know that they’re both great options for storing data, but each has its own strengths and weaknesses. If you want something that’s faster, more reliable, and less likely to fail, then an SSD may be right for you. But if cost is a concern or you don’t need as much speed in your laptop/desktop computer (it takes longer than five seconds to access any file from memory anyway), then go ahead with an HDD instead!
