If you have been a frequent computer user, you might be aware of the terms like a head crash. Sadly, you might even have experienced it too if you had been using the traditional hard drives. This is one of the unhappy circumstances that are associated with hard disks. But these days, people are diverting towards solid-state drives or SSDs to overcome the situations which used to occur in case of hard disk drives or HDDs.
Since all the work these days is handled digitally, there’s no way one would deny the importance of storing the data and maintaining the data records digitally. But for that, the basic thing is to have a drive which is reliable enough to save all the important information on it. HDD and SSD are the two options that have been used today as a medium of the storage device. But which one should be preferred to use? Let’s go into a little depth on the concept and discover which drive should actually be the one to count on with data storage.
What is a hard disk drive (HDD)?
Those who have been using a desktop PC would have definitely worked on traditional hard disk drives, on which you tend to install your operating systems and applications and store your files on it. These drives have a circular disc, which is called a platter and is responsible for storing your data. As the disc spins, it allows the read-write arms to perform the actions of read and write on the disc while it keeps spinning.
The older version of hard drives has an IDE port to connect to the motherboard, but nowadays, the modern hard drives have a SATA connection for connecting with the motherboard. The latest version of SATA used in the hard disk drives is the SATA III, which can be found in the modern motherboards and helps in making the fastest data transfer possible for an HDD.
What is a solid-state drive (SSD)?
After the hard disk drives, came the newer technology of solid-state drive or SSD, which has been adopted in the modern laptops. As the name suggests, this kind of drive does not possess any movable parts. It makes use of NAND flash memory. The NAND memory chips the SSD has, the more will be its storage capacity. With modern technologies, more and more NAND chips have been installed on SSDs, bringing solid-state drives with much more storage capacities.
These days it can be found that the SSDs are coming with SATA III ports, which allow them to be easily installed in the place of an HDD. Also, there are SSDs which comes in the 2.5-inch format, the same format in which the hard drives used to come. But the SATA III connection allows the maximum data throughput of 600MB/s, which can be fine for HDDs but the SSDs are capable of more than this. Thus we can say that the performance of solid-state drives is held back because of the SATA connection.
For the purpose of avoiding the bottleneck, one can have the SSD with PCIe connection. Such kind of drive is connected with the PCIe lane of the motherboard that helps in offering much faster speeds. Another common connection port for solid-state drives is the M.2. If you are using a laptop or any mother desktop with SSDs, it is possible that they would have the M.2 connection. The SSDs that support M.2 connection are usually smaller than the other SSDs, which make them easier to be installed. NVMe or the Non-Volatile Memory Express is the newest SSD technology that is known to offer incredibly fast data transfer speeds.
SSD vs. HDD – A Thorough Comparison
When it comes to storing the files simply, SSDs and HDDs can be seen as the two types of storage media. But leaving this fact, there are numerous ways in which the solid-state drives and hard disk drives are different from each other. Let’s go deep into a thorough comparison between SSDs and HDDs, and then find out which option is better to choose.
SDD vs. HDD: Price
For any normal person, the price is always the main concern and the basis of comparison while buying anything. While choosing between SSD and HDD, the major difference the user will notice is in terms of the prices. It is known that the solid-state drives tend to be more expensive than the hard disk drives per gigabyte.
Not only this, there even are SSDs that are more expensive than others. The older versions of SSDs with SATA III port are cheaper than M2 and PCIe SSDs. But we can’t deny the fact that whether it is in terms of reliability or performance, SSDs are always superior to HDDs. But for those for whom price is a major concern, the HDDs are the cost-efficient option to go with. You can acquire a variety of options in storage spaces and prices of HDDs. You can acquire the hold of some larger HDDs at very low prices, but that might not be a suitable storage device for your confidential and sensitive information.
SSD vs. HDD: Speed
The people who take the performance of the drive as the major concern would definitely find their answer here. It has been found that the performance of the solid-state drives is faster than the traditional hard disk drives. Initially, the SATA III connection bothered the people a lot, but with the upgrading technologies, the SATA III bottleneck in the SDDs has been removed successfully.
The speed of SSD and HDD are measured in megabytes per second or MB/s for both the functions of read and write. In determining the speed of an HDD, there are different factors like capacity. In general, SATA III hard drive at 5,400 RPM will give the speed of around 100MB/s, while the SATA III drive rotating at 7,200 RPM will have a speed of 150MB/s. Because of the fact that the SSDs do not have any moving part, its speed won’t be dependent on the RPMs but will depend on the technology and the data connection.
A solid-state drive with a SATA III connection will achieve 550MB/s read and 520MB/s write speed, which can even be faster in some SSDs to around 600MB/s. On the other hand, the SSDs with PCIe or M.2 port connection can give a speed of the range from 1.2GB/s to 1.4GB/s, and if you have a better budget, there are even SSDs which can offer the speed of 2.2GB/s.
SSD vs. HDD: Capacity
We have already gone through the price and speed as the basis of comparison, now comes the other feature of capacity. Clearly, if your goal is to get a lot of storage space, then HDDs should be your pick. The range of your HDD capacities can go from 40GB to 12TB for the commercial HDDs, and for the enterprise use, it can go further to larger capacities. The 2TB hard disk drives are even available at affordable prices that have got ample storage space to offer.
Earlier SSDs don’t hold up to this much storage space, but nowadays, due to the advanced technologies, the storage spaces have now been taken to terabytes. Though the storage space in SSDs has increased, these options with large spaces come with higher price tags, making it highly expensive to go for.
SSD vs. HDD: Data Safety
Along with the price, speed, and capacity, there’s another constraint that you need to focus on before choosing between SSD and HDD. This one is data security. Whichever drive you pick, you need to be sure that your data on it is safe. Usually, people using hard disk drives might end up losing their data at some point, when they have to seek help from the professionals at hard disk data recovery in Singapore. This is where the SSDs take a step ahead. Because of the fact that SSDs don’t have any moving parts, they can be considered to be more robust than HDD, making it a better choice for laptops.
SSD vs. HDD: Battery Life
Now you have to worry about which kind of storage drive is going to stay more with you. Because of the fact that SSDs use less power in comparison to the HDDs, this would mean that your laptop will be benefitting a lot from the longer battery life when you use an SSD. This is where SSDs can be considered to be more power-efficient than hard disk drives and would also stay alive for a longer time.
When your need is to store the important information on the system, which drive to consider is surely a major decision. You can’t simply pick an option which knowing about it completely. Knowing that there are two options to focus on – SSD and HDD – when your concern is to find something faster, power-efficient, and more robust, solid-state drives should be your option to consider. Though HDDs are available at a lower price, in terms of performance and data safety, there’s no way you can skip giving focus to the SSDs, which are arguably a reliable option to go for.
