SSD vs HDD for External Storage: Which One Should You Buy?

When it comes to external storage, you have two main options: traditional hard disk drives (HDDs) and solid-state drives (SSDs). Each has distinct advantages and drawbacks that make them suitable for different uses.

In this guide, we’ll help you understand the key differences between external SSDs and HDDs and decide which is best for your specific needs.

Now let’s break down each type in detail.

External HDD

External HDDs use traditional spinning disks packaged in a portable enclosure. They offer large capacity at an affordable price but have limitations in speed and durability.

Pros:

  • Budget-Friendly: Typically $20-25 per TB, much cheaper than SSDs.
  • High Capacity Options: Available in sizes up to 18TB or more.
  • Universal Compatibility: Works with virtually any computer with a USB port.

Cons:

  • Slow Performance: Transfer speeds typically 80-130MB/s at best.
  • Mechanically Vulnerable: Can be damaged by drops, bumps, or shocks.
  • Larger and Heavier: Requires more space in your bag or desk.

Ideal For:

  • Backing up large media collections
  • Storing files you don’t access frequently
  • Budget-conscious users who need lots of space
  • Stationary use only: HDDs contain mechanical parts (spinning platters and moving read/write heads) that can be damaged if moved while operating. Even slight vibrations during operation can cause head crashes, potentially resulting in permanent data loss. Avoid using HDDs for on-the-go access or in environments with frequent movement.

External SSD

External SSDs use flash memory with no moving parts and are packaged in smaller, more durable enclosures. They offer dramatic speed improvements and better reliability.

Pros:

  • Much Faster: Transfer speeds from 400MB/s to 1,000MB/s+.
  • Highly Durable: Can withstand drops, vibrations, and temperature changes.
  • Compact and Lightweight: Often pocket-sized and weighing just a few ounces.
  • Lower Power Consumption: Uses less battery when connected to laptops.

Cons:

  • Higher Cost: Typically $80-120 per TB, about 4x the price of HDDs.
  • Lower Maximum Capacities: Most affordable options top out at 2-4TB.

Ideal For:

  • Photographers and videographers needing fast file transfers
  • Gamers storing and playing games directly from external storage
  • Travelers who need durable, reliable storage on the go

Connection Types Matter

The speed of your external drive is limited by its connection type:

  • USB 3.0/3.1 Gen 1 (5Gbps): Supports up to ~500MB/s
  • USB 3.1/3.2 Gen 2 (10Gbps): Supports up to ~1,000MB/s
  • USB 3.2 Gen 2x2 (20Gbps): Supports up to ~2,000MB/s
  • Thunderbolt 3/4 (40Gbps): Supports up to ~3,000MB/s

An external SSD can only reach its maximum speed if:

  1. The drive itself supports high speeds
  2. It uses a fast enough connection type
  3. Your computer has a compatible high-speed port

Important note: Using a fast SSD with an older USB 2.0 port will limit your speeds dramatically to around 40MB/s!

Special Considerations for External Drives

Portability and Durability:

  • SSDs have no moving parts and can withstand drops up to 6 feet
  • HDDs can be damaged by even small bumps while operating
  • For frequent travelers, an SSD is strongly recommended

Gaming from External Drives:

  • Modern games load much faster from SSDs
  • Some games may stutter when run from slower HDDs
  • For PlayStation or Xbox external storage, SSDs provide a much better experience

Backup Considerations:

  • HDDs are cost-effective for backups that run overnight
  • For quick, frequent backups during the day, an SSD’s speed is valuable
  • Consider multiple HDD backups rather than a single SSD for critical data

Which External Drive Should You Buy?

  • If you’re on a budget and need lots of space → Get an External HDD.
  • If you need speed, durability, or portability → Get an External SSD.
  • If you’re a creative professional → Definitely get an External SSD.

For most users, we recommend:

  • A 500GB-1TB External SSD for frequent use, travel, and working files.
  • A 4TB+ External HDD for comprehensive backups and media libraries.
