Things to Consider Before Buying a New External Hard Drive

External Hard Drive

There comes a time when your trusted and long-running storage device, the hard drive, reaches the end of its life. Now you have to bid your old friend goodbye and start looking for a new one. It is a sad moment, but do not fret; we’ve got you covered.

In this article, you will find a list of things to consider before shopping for a new hard drive.

Shopping for a hard drive doesn’t have to be challenging. Don’t worry; there is actually a lot of room for error. You won’t have to stress about selecting the incorrect hard disk if you simply adhere to these recommendations.

Hard Disk Drives or Solid-State Drives?

Whether you require a solid-state drive is the first factor to be taken into account when choosing a data storage device. While SSDs perform essentially the same tasks as conventional hard disk drives (HDDs), they also offer some advantages and disadvantages.

An SSD is a form of data drive that substitutes flash memory for the standard HDDs’ spinning metal discs. An SSD can be compared to a large SD card or USB flash drive.

But How Significant Is That Difference?

SSDs have faster read and write speeds. They use less power, which saves energy and prolongs the life of laptop batteries. SSDs last longer and produce no noise because they don’t contain any moving parts. Since SSDs are more expensive per gigabyte than HDDs at any given price point, they have a lesser data capacity.

Choose a conventional HDD if money is an issue and you require the most storage space possible. Choose a standard HDD if you’re purchasing the drive primarily for data backups and long-term data storage. A good example is HP 687982-001.

Choose an SSD if the drive will house a lot of regularly used files and programs or be used to run an operating system. An SSD has several advantages over an HDD, but speed and performance stand out among all of them.

If you’re looking for suggestions, we have a few. The Seagate BarraCuda H307 3.5-inch internal HDD or the Samsung 870 QVO MZ-77Q8T0B 8TB 2.5-inch internal SSD are both excellent choices. For most scenarios, both are wise choices.

Size and System Consideration

After choosing between HDD and SSD, you must select a form factor. Fortunately, there are only two “actual” options, and the best one depends largely on your configuration.

The 3.5-inch drive and the 2.5-inch drive are two different sizes of data drives.

Data is kept on rotating metal discs in HDDs, hence, more platters are required for a larger amount of data storage. Due to this, desktop HDDs typically have a maximum capacity of 10–20TB and laptop HDDs often have a maximum capacity of 5–10TB.

SSDs are smaller in size than HDDs because they lack moving parts. As a result, the majority of SSDs use a 2.5-inch form factor. What if a 3.5-inch enclosure is too small to accommodate an SSD? You can convert 2.5-inch drives into 3.5-inch drives with some adapters.

The majority of contemporary internal drives (HDD and SSD) use SATA ports for connections. Instead of SATA connectors, earlier internal HDDs that were created before the IDE standard use IDE connectors. However, external drives can connect to your PC via a USB port, no matter if they are HDDs or SSDs.

Some Important Terminologies 

  • Capacity: The quantity of storage required will, of course, influence the solution you choose; generally speaking, hard disk-based devices offer the best value for money in terms of price and storage capacity. The general rule is to buy a hard drive that is twice as large as what you currently require; this should provide for long term goals, especially when you consider that updating an external storage device is more difficult than upgrading a desktop PC.
  • Speed of Transfer: Revolutions per minute (RPM) is a significant component in determining a consumer-grade HDD’s performance. Faster data transfer to and from the drive is made possible by higher RPM. The SATA speed of the drive is unimportant. A contemporary drive might be labelled as having a 3.0GB/s and 7200RPM speed, for instance. The potential maximum speed of a SATA connection is indicated by the first parameter, the SATA speed. This level of speed is unattainable for HDDs. A 7200RPM drive, on the other hand, will always be quicker than a 5400RPM drive.
  • Cache: A hard disc uses a special region of integrated memory labelled as the cache when it needs to transmit data from one part of the drive to the other part of memory. Cache memory is also known as buffer memory. Because more data can be stored at once in a larger cache, data transfers more quickly. Cache sizes on contemporary HDDs can range from 8MB to 256MB.
  • Read and Write Speed: The duration it takes for the device to arrange itself to read data from or write data to a typical Hard drive is one of a few additional elements that affect performance. There isn’t a consistent way to compare access times, even while two 7200RPM drives might behave differently (for instance, one of them might be slower at moving the disc reader). Additionally, most hard drives now operate similarly, so you shouldn’t worry too much about this specific feature.
  • Rate of Failure: As moving parts, HDDs are subject to wear and tear over time, albeit not all HDDs deteriorate at the same rate. While certain models tend to fail within a year, others have an estimated longevity of more than six years. It is your duty to conduct model-specific research before committing to a purchase.

The Cost of Hard Drive

You’ll find a broad range of hard drive prices for products that all appear to be fairly comparable when you shop. You must choose the features and specifications that are most important to your requirements before choosing a hard disk that meets them.

To calculate the price per gigabyte, you can, however, divide the drive’s cost by the amount of storage it can hold. A cheap option is HP 687982-001.

The Security of Storage 

Traditional hard disks drive-based storage devices are naturally brittle, but some are more so than others, especially the larger ones that are more vulnerable to harm when dropped.

Better grab a flash drive than a spinning hard disc if you anticipate it taking a beating, as well as the occasional drop.

Manufacturers pair up two hard drives to increase the redundancy of external storage devices if one of the drives fails. Moreover, Seagate offers a powerful encryption option that keeps your data secure and hidden from cyber threats.

Final Words

Hard Drives are the first choice for consumers who want a large storage capacity. Hard drives resolve all of the storage issues and give you reliability and safety to ensure your important work data, retain your games’ last checkpoints, and capture memorable pictures of your trip.  Buy HP 687982-001 from
