IP ratings and drop ratings explained
An IP code contains two digits. As the IEC's IP rating overview explains, the first digit indicates protection against dust and solids. The second indicates protection against water. Higher numbers mean greater protection.
Here is what the ratings mentioned on this page mean:
- IP54: dust-protected and resistant to splashes. Reviewers cite this class for the LaCie Rugged line.
- IP55: better water protection, covering jets rather than just splashes. Commonly used in SanDisk Extreme Portable marketing.
- IP65: dust-tight with protection against water jets. Samsung's T7 Shield title claims this rating.
- IP67: dust-tight and protected against temporary immersion.
- IP68: dust-tight and protected against longer immersion. Depth and time limits are set by the maker, so check the individual product page.
For example, PCMag UK reports that the SD820 is waterproof to about 3 feet for 30 minutes, provided its port cover is fitted.
Drop ratings are less straightforward because there is no single standard. Figures can come from makers or reviewers, so only claims backed by a named source are quoted here.

The picks
ADATA SD820: best rugged SSD for most
PCMag UK rates the SD820 as the best ruggedised external drive for most people. It has an IP68 rating when the port cover is fitted and connects through USB 3.2 Gen 2x2. Speeds reach up to 2,000 MB/s with a compatible host. PCMag also lists capacities up to 4TB.
Who it suits: surveyors, photographers and travellers looking for a compact, sealed SSD with fast transfer speeds.
Who should skip it: anyone who needs built-in AES encryption. PCMag confirms that the SD820 lacks this feature. Use your operating system's encryption instead, or see our encrypted drive guide.
Amazon UK listed this 2TB model as usually dispatched within 2 to 3 days when checked on 6 November 2026. The listing title calls it an SD820, but the model-number field says SD810. Confirm the exact model with the seller or the maker before you buy.
ADATA HD710 Pro: best IP68 hard drive
The HD710 Pro's listing claims IP68 waterproofing alongside shockproof and dustproof protection. It uses USB 3.1 and is listed on Amazon UK in 1TB, 2TB and 4TB versions.
Who it suits: tradespeople and site teams who need plenty of storage for the money, with a protective shell suited to wet and dusty conditions.
Who should skip it: people transferring large video files every day. Being an HDD, it favours capacity over speed. Its spinning disks are also generally less resistant to knocks than an SSD.
Stock was low for several capacities when checked. The 4TB listing, linked above, showed only 1 left on the main offer on 6 November 2026.
Stock was limited and varied when checked on 6 November 2026. Confirm current stock and seller before ordering.
LaCie Rugged Mini: best classic rugged HDD
The LaCie Rugged Mini is easy to recognise by its orange rubber bumper. This particular listing uses USB 3.0.
A vividrepairs.co.uk review of the LaCie Rugged hard drive line reports IP54 protection against dust and splashes, along with about 1.2 m drop resistance when the rubber bumper is fitted. Check that these specifications apply to the exact SKU before buying.
Who it suits: anyone who wants an established, bumpered hard drive to carry around every day.
Who should skip it: anyone needing waterproof storage. IP54 protects against splashes, not immersion.
Stock and offers varied when checked on 6 November 2026. Confirm that your selected offer is new rather than Amazon Resale, its condition, stock and seller before ordering.
Samsung T7 Shield: IP65 SSD with password features
The Amazon title for the T7 Shield claims IP65 water resistance. The drive connects through USB 3.2 Gen 2, and password encryption is available across the T7 Shield family. It also appears in PCMag UK's coverage of rugged drives.
Who it suits: travellers after a lightweight SSD with password protection and reasonable resistance to water.
Who should skip it: anyone who needs protection against immersion. An IP68 drive is the better option for that requirement. For more detail on encryption, see our encrypted drive page.
G-DRIVE ArmorATD: best high-capacity field HDD
The SanDisk Professional G-DRIVE ArmorATD features among TechRadar's recommended rugged drives. Western Digital describes it as a portable rugged external hard drive, with a 5TB USB-C version available.
Who it suits: field teams and content creators who need substantial storage for footage and archives in a single rugged enclosure.
Who should skip it: buyers who need to know the precise IP rating before ordering. Check the Western Digital or SanDisk Professional product page to confirm the rating.
Stock and offers varied when checked on 6 November 2026. Confirm that your selected offer is new rather than Amazon Resale, its condition, stock and seller before ordering.
SanDisk Extreme Portable: best fast portable SSD
The newer SanDisk Extreme Portable 1TB is listed with speeds of up to 2000MB/s over USB-C. SanDisk commonly advertises its Extreme Portable range as IP55-class for dust and water resistance, but the exact rating should be checked against the SKU on the maker's website.
An older model rated at 1050MB/s remains on sale, so check the version carefully before buying.
Who it suits: people who want a compact, fast SSD for everyday travel.
Who should skip it: anyone who requires a published drop rating or protection against immersion.
Stock and offers varied when checked on 6 November 2026. Confirm that your selected offer is new rather than Amazon Resale, its condition, stock and seller before ordering.
High-end option: PCMag also includes the LaCie Rugged SSD Pro5 in its coverage of Thunderbolt drives for creators. UK stock could not be confirmed when this page was checked.
Which drive suits which job?
- Site survey: choose the ADATA SD820 for quick file transfers and a sealed design that protects against rain and dust.
- Photographer: the SD820 or SanDisk Extreme Portable offers speed, while a G-DRIVE ArmorATD back at base provides archive storage.
- Van and trades: the ADATA HD710 Pro offers capacity. For tighter budgets, consider the Transcend StoreJet 25M3 or Silicon Power Armor A60.
- Lab and industrial: an IP68 drive is worth considering around dust or liquids. Check the maker's operating temperature limits too.
Field practice: protect the data, not just the drive
A rugged enclosure helps reduce the chance of physical damage. It is not a substitute for keeping backups.
- Keep a second copy. Transfer each day's work to another drive before leaving site.
- Follow 3-2-1. Keep three copies of your data on two different types of media, with one copy stored off-site.
- Label every drive. Include the project, date and owner so it is clear what belongs where.
- Close port covers. IP protection claims generally depend on the covers being properly sealed.
- Check temperature limits on the maker's website before leaving a drive inside a hot van.
For storage back at the office, see our guides to the best external hard drive for business backup, the best NAS for small business and the best UPS for small office.
A rugged drive helps protect the hardware, but does not make a business compliant on its own.
FAQ
What does IP68 mean for a hard drive?
Under the IEC IP code, the 6 means the drive is dust-tight, while the 8 indicates protection against continuous immersion. The maker specifies the depth and duration.
For the SD820, PCMag reports protection to about 3 feet for 30 minutes, with the port cover fitted.
Are rugged drives worth it?
Generally, yes, for site, field and travel work. Both PCMag and TechRadar cover rugged drives suited to these uses. If a drive rarely leaves your desk, a standard model is usually sufficient.
SSD or HDD for field work?
SSDs are faster and have no moving parts, making them better at coping with knocks. HDDs offer more storage for the money, so they make sense for archives.
Which external drive survives drops?
Stick to drop resistance figures published by the maker or a reviewer. For example, vividrepairs.co.uk reports about 1.2 m drop resistance for the LaCie Rugged line it reviewed.
Is LaCie Rugged waterproof?
No. The reviewed LaCie Rugged hard drive line is rated IP54, providing protection against dust and splashes. It does not offer the immersion protection associated with IP68.
