Things You Must Know before Purchasing a New Hard Drive

Data consumption is skyrocketing and our dependency on data storage has never been this high, be it computers, laptops, or gaming devices. External storage devices have become the ideal solution for your back up needs. Not only do you need it for the storage requirements but it also affects the performance of your computing devices to a great extent. When it comes to buying a hard drive, there are a number of options available. how do you know what’s right for you? Here are some of the things to consider when purchasing the new hard drive.

(1).  Solid State Drive (SSD) vs Hard Disk Drive (HDD)

One of the very first things you must consider is whether to buy SSD or HDD.  Fundamentally, their purpose is the same but both of them have their own advantages and disadvantages.
A hard disk drive (HDD) is an old-school non-volatile storage device that uses a series of platters covered by a ferromagnetic coating and a moving read/write head to access data. A solid-state drive (SSD) is a newer, faster type of device that stores data on interconnected flash memory chips. So, it does not have the disks that spin like in the traditional HDD.
SSD is faster and requires less power. They are almost noiseless and more durable. HDD on the other hand offers larger data capacities and is cheaper. If the price is your concern and you need lots of storage, HDD would be your option.

(2). External or Internal?

The foremost thing to keep in mind is whether you need an internal hard drive or external drive?
If you simply want an external drive for data storage and backup solution then External drives are perfect. They are easy to connect, detach, and supports direct media playback. In addition, external drives are portable and can be used for multiple devices.
If you need only speed and not looking for portability and reliability, then go for an internal drive. External Hard drives are more prone to data loss thus requiring data recovery.

Hence, you can decide whether you need an HDD or portable drive based on your requirement.

(3). HARD DRIVE STORAGE CAPACITY

Storage capacity is one of the essential specifications to consider when buying an external drive. It’s no good buying a hard drive with other functionalities if it’s not big enough to store your information. however, If you are confused about the storage capacities of each type of drive, let me tell you there are no differences in storage capacity. You can get HDDs and SSDs in similar sizes. hard drives range in capacity from 250 gigabytes to several terabytes.

However, larger SSDs are more expensive than HDDs when measured by cost per Gigabyte of storage,. so let’s talk about…(4). Pricing

The market for hard drives is volatile, and it varies based on supply and demand.SSD’s are slightly more expensive than HDD’s, While the price for SSDs has decreased a lot, there is still a significant price difference. A 500 GB HDD comes within a range of $25 – $50 (for faster, higher-end models), whereas a 500 GB SSD ranges around $60 – $150. Naturally, these numbers will change over time.

The price of the hard drives is determined by the above factors, as well as other factors include transfer speed, access time, cache space, and a few more. All in all, the Two hard disks offering the same storage capacity can be priced differently depending upon the brand and quality.

(5). Which hard drive is better for gaming?

An average High-end graphic game consumes huge amounts of data, your hard drive choice can significantly impact the performance of games. which is why we always recommend SSDs for gaming. an SSD help games load and run faster. You’ll also experience less stutter when playing games, you don’t need to wait for game data to load on your devices – which can give a nice gaming experience.
wherein, HDD can affect waiting times and game responsiveness.
Gamers should look for auto-backup features and universal compatibility which may fit your requirements.

(6). The physical size and form factor

Once you have chosen between SSD and HDD, you will need to consider the form factor. The good thing is there isn’t much to choose from and this spares you from a great deal of confusion. There are only two form-factors available today, 2.5 – 3.5 inches.
The traditional hard drives use the spinning disks made of metal platters and thus for more storage capacity, there is a necessity for more space. This is the reason why most of the HDDs for desktop have a form factor of 3.5 and offer storage capacity up to 4TB. The HDDs for laptops have a maximum storage capacity of 2TB with a form factor of 2.5. On the other hand, higher capacity SSDs can fit in a 2.5-inch form factor.

(7). The performance

Here are some factors that decide the performance of your hard drive

Transfer speed:

It’s no surprise that people evaluate the expected performance of the hard drives, they look at the RPM specification.

The transfer speed can vary a lot depending on the drive model, even if it’s the same type of drive, so it’s always a good idea to check the specifications on the first-hand and if possible, try to do a manual test with that particular drive. In addition, there are certain limitations depending on the type of drive and its interface.today’s The most common RPM rates, in both laptop and Pc desktops, are between 5,400 and 7,200 RPM. a 7,200 RPM drive can deliver data about 33% faster than the prior. Consequently, this specification is important when evaluating and comparing the expected performance of different hard drives.

Cache:

A cache is like a virtual memory chip in hard drive. When accessing data, the data will be exchanged between drive and memory. Therefore, if a hard drive has a large cache, the system load can be reduced and data transmission speed will be increased greatly. Thus, more cache space means faster data transfer. So, It better to check the cache capacity of the drive before-hand

Power consumption:

Power consumption has become increasingly important, not only in mobile devices, laptops but also in server and desktop markets.  over usage and heat dissipation has led to problems delivering sufficient power to devices (especially for spin-up), and getting rid of the waste heat subsequently produced. Heat dissipation is tied directly to power consumption, and as drives get older, disk failure rates increase at higher drive temperatures. Many of the hard drive companies are now producing Green Drives that require much less power and cooling. Many of these Green Drives spin slower (<5,400 rpm compared to 7,200, 10,000 or 15,000 rpm) thereby generating less heat.
