Using a solid state drive (SSD) as an external drive can be a great option for many users. SSDs have advantages over traditional hard disk drives (HDDs) in terms of speed, durability, and size. However, there are also some potential downsides to consider. In this comprehensive guide, we’ll look at the pros and cons of using an SSD as an external drive to help you decide if it’s the right choice for your needs.
The Benefits of Using an External SSD
Here are some of the biggest advantages of using an external SSD:
- Faster transfer speeds – SSDs have much faster read/write speeds compared to HDDs, thanks to flash memory and the lack of moving parts. This makes them better for transferring large files quickly.
- Better durability – With no moving parts, SSDs are less susceptible to damage or wear and tear if you drop or bump them while plugged in. HDDs have fragile platters and heads.
- Compact size – 2.5″ SSDs are much smaller than most portable HDDs. This allows for easy portability.
- Low power consumption – SSDs use less energy than HDDs, which means longer battery life if you’re using a laptop.
- Makes older laptops feel faster – Upgrading an old laptop to use an external SSD can provide a big speed boost for programs and files.
- Ideal for frequent unplugging – The lack of moving parts also makes SSDs better able to withstand frequent unplugging/re-plugging.
For many users, the biggest motivator for using an external SSD is the potential for much faster file transfers. If you frequently move large files like videos, photos, games, etc., the speed advantage of SSDs makes a noticeable difference over HDDs. Portability is another major factor, since external SSDs are compact and smooth.
Drawbacks of Using an External SSD
However, there are some downsides or compromises to consider as well:
- Higher cost per gigabyte – SSDs are more expensive than HDDs in terms of cost per gigabyte. Paying extra for an SSD may not be worth it if you just need massive amounts of external storage.
- Risk of failure – Though rare, SSDs can fail unexpectedly, while HDDs usually show warning signs. Always keep backups.
- Shorter lifespan – SSDs can wear out after a number of write cycles. HDDs have longer operational lifespans.
- Susceptibility to damage from drops – If an SSD suffers a hard physical jolt while powered on, there is a risk of data corruption.
- Overheating risks – Compact SSD designs can sometimes lead to overheating, especially if airflow is restricted.
For users who just need tons of external storage space for backups or media libraries, HDDs provide much more cost-effective gigabytes. And though their failure rates are low, SSDs carry more catastrophic risks if they fail unexpectedly or are damaged while powered on. Proper backups are essential to minimize data loss.
Factors to Consider When Choosing an External SSD
If you decide an external SSD meets your performance and portability needs, there are several factors to look at when choosing a specific model:
- Storage capacity – External SSDs are available in sizes from 120GB to 8TB. Consider your needs in the short and long term.
- Physical size – Common external SSD sizes are 2.5″ and M.2/NVMe. 2.5″ drives use USB while M.2 use Thunderbolt or USB-C.
- Read and write speeds – Faster SSDs can reach up to 1000+ MB/s. Pay for performance you need.
- Connection type – Common ports are USB 3.2, USB-C and Thunderbolt 3. This affects speed capabilities.
- Ruggedness rating – Some external SSDs come with rugged ratings like IP68 for dust/water resistance.
- Security features – Encryption like AES-256 and added security layers can help protect sensitive data.
- Warranty length – Longer warranties (3-5 years) provide more coverage in case of failure.
- Brand reputation – Stick with major brands like Samsung, WD, SanDisk for proven reliability.
Also consider software factors like compatible operating systems, transfer utilities for faster throughput, and backup/recovery tools. The right external SSD can provide a major portability and performance upgrade over HDDs.

Using an External SSD on Consoles like PS5
Using an external SSD provides several benefits when connected to game consoles like PS5 and Xbox Series X/S:
- Games load much faster due to higher read speeds from the SSD.
- Faster transfer of games between storage and console.
- No slowdown as internal storage fills up.
- Take your games and settings to another console easily.
- Store more games than limited internal SSD space allows.
For optimal performance, choose an external SSD with high sequential read/write speeds above 500MB/s. Many SSD models designed for gaming and consoles are available. USB 3.2 Gen 2×2 provides faster transfer speeds up to 2000MB/s. Some tips for using an external SSD on PS5 and Xbox:

- Handle SSD carefully as jolts and drops can damage components while powered on.
- Keep the SSD in a protective case if taking it on the go to reduce physical stresses.
- Avoid exposing external SSD to liquids, dust and debris which can damage circuitry.
- Do not place heavy objects on top of external SSD which can pressurize and deform the drive.
- Maintain backups of your most important data in case an SSD fails unexpectedly.
- Use the SSD manufacturer’s disk utility software for performance testing, firmware updates and drive monitoring.
- Enabling encryption adds an extra layer of security for sensitive personal data stored on the SSD.
- Register the external SSD’s unique ID on the manufacturer’s site for warranty purposes.
Following best practices like these will help ensure your external SSD enjoys a long lifespan of fast and reliable service.
External SSD vs Portable HDD
How does an external SSD compare to a portable external hard disk drive (HDD)? Here’s a quick rundown of the key differences:
| External SSD | Portable HDD | |
|---|---|---|
| Cost per GB | Higher | Lower |
| Transfer speed | Faster | Slower |
| Durability | Better – no moving parts | Sensitive moving platters |
| Power usage | Lower | Higher |
| Capacity | Up to 8TB | Up to 10TB+ |
| Size/portability | More compact | Larger and heavier |
In summary, external SSDs excel in transfer speed, durability, power efficiency and portability. But portable HDDs offer far more storage capacity for the price. For users who value speed and mobility, external SSDs are a great choice despite the higher cost per gigabyte.
Conclusion
Using an external SSD comes with many benefits thanks to solid state flash memory inside these compact drives. Faster transfer speeds, improved durability and smaller size make them a better choice than external HDDs for some users. However, the higher cost per gigabyte means HDDs are far better for affordable high capacity external storage.
When shopping for an external SSD, factors like connection type, read/write speed, ruggedness and security are important to consider based on your specific needs and budget. Leading external SSD manufacturers include Samsung, WD, SanDisk, ADATA and others.
For console gamers, upgrading to an external SSD can massively improve game load times and performance. Just be sure to choose an SSD with excellent sequential read speed. With proper care and maintenance, an external SSD can retain its fast performance for years before reaching its write cycle limit.
