The Ultimate Buyer’s Guide: How to Choose The Right Product for You

Key Factors to Consider

• Interface (SATA vs. NVMe): This is the most crucial factor. SATA 2.5-inch drives (like the Samsung 870 QVO/EVO) are compatible with almost all desktops and older laptops and offer speeds around 550 MB/s. NVMe M.2 drives (like the Samsung 980 Pro or WD_BLACK SN850X) are small sticks that plug directly into the motherboard, offering speeds from 3,500 MB/s (PCIe 3.0) to over 7,000 MB/s (PCIe 4.0). Always check your motherboard or laptop specs to see what it supports.
• Capacity: How much space do you need? 500GB is a decent starting point for an operating system and key applications. 1TB is the sweet spot for most users, offering room for the OS, apps, and a good number of games. 2TB and above are ideal for hardcore gamers, content creators, or those who want to store a large media library.
• Read/Write Speeds: Higher speeds mean faster boot times, quicker application loading, and speedier file transfers. While top-end NVMe drives boast the highest numbers, even a basic SATA SSD provides a monumental real-world improvement over a mechanical hard drive (HDD).
• Endurance (TBW): Terabytes Written (TBW) is a rating of how much data can be written to the drive over its lifetime. For most users, even budget SSDs have a TBW rating that will last for many, many years of normal use.

Understanding NVMe vs. SATA: What’s the Real-World Difference?

On paper, the difference between a SATA SSD (max ~560 MB/s) and a top-tier PCIe 4.0 NVMe SSD (~7,300 MB/s) is enormous—over 12 times faster. For certain tasks, this difference is transformative. If you frequently move massive files (e.g., editing 4K video or working with large datasets), the time saved with an NVMe drive is substantial. However, for everyday tasks like booting up your computer, opening a web browser, or loading most games, the difference is much less dramatic. The initial leap from a slow HDD to any SSD is the biggest performance jump you’ll experience. The move from a SATA SSD to an NVMe SSD is a smaller, though still noticeable, improvement for general responsiveness. The bottom line: if your system supports it and your budget allows, NVMe is the faster choice, but a quality SATA SSD is still an excellent and highly effective upgrade.

Common Mistakes to Avoid

• Ignoring Compatibility: Buying an M.2 NVMe drive for a laptop that only has a 2.5-inch SATA bay. Always double-check your device’s specifications before purchasing.
• Forgetting the Screw: M.2 drives require a tiny screw to hold them down on the motherboard. Most motherboards include this, but they are easy to lose. The drives themselves almost never come with one.
• Skipping the Heatsink: High-performance PCIe 4.0 NVMe drives can get very hot under sustained load, causing them to “throttle” or slow down to protect themselves. Using a heatsink (either one that comes with your motherboard or an aftermarket one) is essential to get the performance you paid for.

Frequently Asked Questions

What is the most durable and rugged external SSD for travel and work?

While this list focuses on internal drives, many users place them in external enclosures for portable use. SSDs are inherently more durable than traditional HDDs because they have no moving parts, making them highly resistant to shocks and drops. A standard 2.5-inch SSD like the Samsung 870 EVO 1TB Internal SSD inside a quality, padded external enclosure creates a very reliable and rugged portable drive suitable for travel and work.

What connection do I need for the fastest external SSD speeds (e.g., USB 3.2 Gen 2, Thunderbolt 4)?

To get the maximum speed from an external SSD, the connection type is critical. For an external SATA SSD, a USB 3.2 Gen 1 (5Gbps) port is sufficient. For a high-speed external NVMe drive, you’ll need a USB 3.2 Gen 2 (10Gbps), USB 3.2 Gen 2×2 (20Gbps), or ideally a Thunderbolt 3/4 (40Gbps) port and a compatible enclosure to unlock its full potential.

Are external SSDs fast enough to edit 4K video from directly?

Yes, absolutely. A SATA SSD in a USB 3.2 Gen 2 enclosure is fast enough for most 4K editing workflows. For more demanding, multi-layer 4K or 8K projects, using a fast NVMe drive like the WD_BLACK SN850X 2TB NVMe SSD in a Thunderbolt 4 enclosure provides exceptional performance, allowing you to edit directly from the drive without lag or stuttering.

How can I password protect and encrypt the data on my external SSD?

Most modern operating systems have built-in encryption tools. Windows has BitLocker, and macOS has FileVault. When you format your external SSD, you can choose to enable these tools, which will encrypt the entire drive and require a password for access. For an extra layer of security, some brands like Samsung offer their own software that supports hardware-based AES 256-bit encryption on select models.

What is the practical difference between a portable SSD and a portable HDD?

The difference is night and day. A portable SSD is significantly faster (5-20x faster), much smaller and lighter, more durable as it has no moving parts, and silent. A portable HDD is much slower, bulkier, fragile, and makes audible spinning and clicking noises. The only advantage of an HDD is its lower cost per gigabyte, making it suitable for cheap, high-capacity backups where speed is not a priority.

Can I use an external SSD to expand my Xbox Series X/S storage?

You can use a standard external USB SSD to store Xbox Series X|S games, but you cannot play them directly from it; you must transfer them to the internal drive first. The only way to play Series X|S games from an external drive is by using the officially licensed Seagate 1TB Storage Expansion Card for Xbox Series X|S, which plugs into a special port and perfectly matches the speed of the internal SSD.

Which brands offer the best warranty for external SSDs in the UK?

Premium brands like Samsung and WD_BLACK typically offer the best warranties, with many of their high-performance drives, such as the Samsung 980 PRO and WD_BLACK SN770, coming with a 5-year limited warranty. Crucial also offers strong warranties. Always check the specific product page, as warranty length can vary between different models from the same brand.
