The Best External Drive

An external drive is one of those purchases you don’t think about until you absolutely need it.

Whether you’re backing up years of family photos, transferring large video projects between computers, or simply freeing up space on a laptop with limited storage, the right external drive can save you hours of frustration.

But with so many options on the market, ranging from budget-friendly portable HDDs to high-speed SSDs, it’s easy to feel overwhelmed. That’s where this guide comes in.

At BestProducts, we evaluate each external drive against consistent criteria: specifications, expert review consensus, verified buyer feedback, and published data. Every product receives a BP Score on a 0, 10 scale, so you can compare at a glance.

After analyzing the top contenders, we’ve curated a list of the best external drives worth your attention. Below are our top picks, followed by a detailed buying guide to help you choose the right one for your needs.

External Drive Buying Guide

Capacity and Storage Type

The first decision is capacity. For everyday document backups and light media storage, 500GB to 1TB is often sufficient. If you work with 4K video, large photo libraries, or multiple game installations, consider 2TB to 5TB.

Most portable HDDs top out at 5TB, while SSDs are available in smaller capacities but offer faster speeds.

Storage type matters just as much. Traditional hard drives (HDDs) are cheaper per gigabyte and ideal for bulk storage. Solid-state drives (SSDs) are faster, more durable, and completely silent, making them a better fit for active use and travel.

If you need a balance of speed and capacity, a hybrid approach (using both an HDD for archives and an SSD for active projects) is worth considering.

Speed and Interface

Interface directly affects transfer speeds. USB 3.0 (now USB 3.2 Gen 1) offers up to 5 Gbps, which is fine for most HDDs. USB 3.2 Gen 2 doubles that to 10 Gbps and is common on SSDs.

Thunderbolt 3 and 4 provide even higher throughput but are typically found on premium external SSDs for professionals.

For everyday use, USB 3.0 or USB-C (with USB 3.2 Gen 2 support) is more than adequate. If you frequently transfer large files, an SSD with a USB 3.2 Gen 2 interface can cut wait times dramatically.

Check your computer’s ports before buying, some older laptops lack USB-C, so a drive with a detachable cable or included adapter is handy.

Portability and Durability

If you plan to carry your drive daily, size and weight matter. Portable HDDs are typically 2.5-inch drives weighing under 200 grams, while SSDs are even lighter and more compact. Rugged models add rubber bumpers and water/dust resistance (IP ratings) for outdoor or job-site use.

For occasional travel between home and office, a standard portable HDD is fine. For frequent commuters or photographers in the field, an SSD with shock resistance and an IP65 rating (like the Sandisk Extreme) offers peace of mind.

Also consider cable management: some drives have integrated USB-C cables, reducing clutter.

Security and Software

Many external drives come with built-in encryption or backup software. Hardware encryption (AES-256) protects data if the drive is lost, while password protection adds a layer of security. Some brands, like WD with My Passport, offer automatic backup and ransomware defense.

If you handle sensitive information, look for drives with hardware encryption and software that works across Windows and macOS. For simple drag-and-drop storage, a plug-and-play drive without extra software is perfectly fine.

Seagate’s Rescue Service (one-year data recovery) is a valuable bonus for critical backups.

Frequently Asked Questions

What is the difference between an external HDD and an external SSD?

HDDs use spinning magnetic platters and are cheaper per gigabyte, making them ideal for large backups. SSDs use flash memory, offering faster read/write speeds, greater durability (no moving parts), and silent operation.

SSDs are better for active use and portability, while HDDs are still the best value for bulk storage.

How much storage capacity do I need?

For document backups and light media, 500GB to 1TB is usually enough. For photo libraries, game installations, or video projects, 2TB to 5TB is recommended. If you need massive archives, consider a desktop external drive with 8TB or more, though those are less portable.

Can I use an external drive with both Windows and Mac?

Most external drives are formatted for Windows (NTFS) out of the box. Macs can read NTFS but not write without third-party software. For cross-platform use, reformat the drive to exFAT, which works on both systems.

Some drives come pre-formatted for Mac or include a utility to switch formats.

Is USB 3.0 fast enough for video editing?

USB 3.0 (5 Gbps) is sufficient for editing 1080p video from an HDD. For 4K or higher, an SSD with USB 3.2 Gen 2 (10 Gbps) or Thunderbolt is recommended to avoid lag. If you work directly from the drive, choose an SSD for the best experience.

Do external drives come with backup software?

Many brands include basic backup software. WD offers WD Backup and password protection with hardware encryption on My Passport drives. Seagate provides Toolkit for backup and sync, plus a one-year Rescue Service for data recovery.

Some users prefer to use built-in OS tools (Time Machine for Mac, File History for Windows) instead.

How durable are portable external drives?

Standard portable HDDs can survive minor drops if kept in a padded case. SSDs are more shock-resistant and often have IP ratings for water and dust.

Rugged models (like the LaCie Rugged series or Sandisk Extreme) are designed for outdoor use. Always handle drives carefully and consider a protective sleeve.
