Show more Factors to consider when choosing an external hard drive External hard drives may not be the most exciting pieces of technology, but it's amazing how quickly people become interested in them after experiencing data loss. The following are things to consider when trying to choose the right external hard drive for your needs, and what I considered in creating this guide:Reliability:I've selected external hard drives from top-name brands to ensure the highest reliability. Hard drives are inherently reliable, and the products chosen are expected to offer about 5 to 7 years of effective life, after which it is advisable to replace them.Features: The selection includes basic drives for those with modest requirements, as well as models equipped with advanced features such as hardware encryption, water and dust resistance, and drive redundancy for added data protection.Capacity: The products come in a variety of capacities, allowing users to select a size that meets their needs without paying for unused storage space.Desktop or portable: Some want an external hard drive for use on a desk, others will want to take it with them. Generally, those with a 2.5-inch form factor are portable units, while 3.5-inch units are best forstatic desktop use.Price:I've ensured there is a range of prices to accommodate all budgets. Everyone deserves the opportunity to back up their data securely and affordably. Show more How we test external hard drives Having worked with technology for nearly three decades, and been a pro-am photographer and videographer for much of that time (so I've been testing and using backup solutions for many years), I've handled and tested a wide array of external hard drives from various manufacturers. With the exception of the SanDisk Professional G-Drive ArmorATD -- which is new to me, though I've owned an earlier version -- I have personally used all the drives listed in this guide. This gives me a practical understanding of what they offer in terms of features, performance, and long-term reliability.Additionally, I've considered user reviews to identify and exclude products that may have design flaws or reliability issues. Show more What is the difference between an SSD and an HDD external hard drive? SSD (Solid State Drive) and HDD (Hard Disk Drive) are two types of storage technologies used in external hard drives. SSDs are faster, more durable, and use less power because they have no moving parts, making them ideal for frequent transport and high-speed data transfer.HDDs, on the other hand, offer larger storage capacities at a lower cost per gigabyte but are generally slower and more susceptible to damage from physical shocks due to their moving parts.Also: The best SSDs Show more How do I choose the right capacity for my external hard drive? The appropriate capacity for your external hard drive largely hinges on your individual storage requirements. It's important to consider the types of files you intend to store, such as documents, photos, videos, or software, and their respective sizes.As a general guideline, a drive ranging from 500GB to 2TB ought to suffice for most users. However, for those dealing with significant volumes of high-resolution media files or needing backups for multiple devices, opting for a drive with a capacity of 4TB or more may be necessary.To make an informed decision, assess both your current and future storage needs. My recommendation is to estimate your present data volume and then double that storage capacity; this approach should adequately serve you for at least the next year or so. Show more Can I use one external hard drive for both Windows and Mac computers? Yes, you can use one external hard drive with both Windows and Mac computers, but it will require formatting the drive in a file system that is compatible with both operating systems.The exFAT format is widely recommended for this purpose because it is supported by both Windows and Mac without the file size limitations of FAT32. However, formatting the drive will erase all data on it, so be sure to back up your files before proceeding, otherwise you could be in a world of hurt.Note that many external hard drives come pre-formatted for one operating system, but can be reformatted for use with another.
