How to Choose an External SSD
When shopping for an external SSD, focus on these three things.
1. Transfer Speed The most impactful spec is read speed. Models with USB 3.2 Gen 2 support can reach up to 1,050MB/s, making large file transfers quick and painless. If you regularly move big files – video footage, photo libraries, game installs – speed will be the difference you feel most.
2. Durability and Weather Resistance If you carry your SSD in a bag or use it outdoors, look for IP65 or higher dust and water resistance. Drop protection (rated in meters) is also worth checking. A rugged SSD gives you peace of mind whether you are on a film set, a hiking trail, or just commuting.
3. Capacity and Price Balance The 1TB tier is the current sweet spot, offering the best price per gigabyte. If you handle large video projects or need to archive a lot of data, consider 2TB or 4TB. Smaller capacities exist, but the per-GB cost is usually less favorable.

It works with both USB-C and USB-A devices, covering virtually every computer you own.

2. SanDisk Extreme V2 – Ultralight and Hugely Popular

It has long been a favorite among photographers and content creators. AES 256-bit hardware encryption is included for data security.
3. Crucial X9 – Best Value for Money
The Crucial X9 delivers the same 1,050MB/s read speed as the pricier competition at a noticeably lower price. At just 39g, it is the lightest SSD in this roundup – small enough to forget it is in your pocket. If you are buying your first external SSD and do not want to overspend, this is the model to get.
4. Samsung T7 – Trusted Classic with Fingerprint Security
The Samsung T7 is the standard (non-rugged) sibling of the T7 Shield. It trades water resistance for a fingerprint reader, making it a great choice for professionals carrying sensitive business data. The slim aluminum body looks and feels premium, and Samsung’s track record for reliability speaks for itself.
5. BUFFALO SSD-PHP – Rugged with Japanese Support
BUFFALO is a leading Japanese peripherals brand known for excellent domestic customer support. The SSD-PHP offers IP55 water and dust protection plus MIL-STD shock resistance. It also comes with easy backup software, which is helpful if you prefer a guided setup. A solid choice for anyone who values after-sales support.
6. KIOXIA EXCERIA PLUS G2 – Quality Flash Memory from Japan
KIOXIA (formerly Toshiba Memory) manufactures its own flash memory, giving this SSD a strong pedigree. The EXCERIA PLUS G2 matches the 1,050MB/s read speed of the top-tier models in a compact body. It includes a free data recovery software download as a bonus. For buyers who appreciate Japanese engineering and vertically integrated quality, this is a compelling option.
Summary
For most people, the Samsung T7 Shield is the best external SSD to buy. It combines fast transfers, serious durability (IP65 + 3m drop resistance), and broad compatibility into one well-rounded package. If budget is your main concern, the Crucial X9 offers the same speed at a lower price point. Whatever your needs, start by deciding whether you need rugged protection or can save money with a standard model, then choose accordingly.
