SP Silicon Power vs Apricorn Specs
Physical durability
The Silicon Power Armor A80 is built for physical resilience. It meets the US Military Drop Test Standard MIL-STD810F for transportation drops. It also holds an IPX7 waterproof rating, meaning it can survive immersion in water. This makes it suitable for outdoor or rugged environments. The Apricorn Aegis Padlock DT does not list specific drop or waterproof ratings in its published specifications. It focuses on security features rather than physical ruggedness. If you need a drive that withstands physical abuse, the Silicon Power model provides clear protective specifications that the Apricorn drive lacks.
Security features
Security is the primary focus of the Apricorn Aegis Padlock DT. It includes 256-bit encryption and separate admin and user modes. The drive supports forced enrollment and data recovery PINs. It also features programmable brute-force defense to protect against unauthorized access. The Silicon Power Armor A80 mentions a free downloadable widget for data encryption, but it does not specify the encryption standard or hardware-level security features. For users who need robust, built-in data protection and access control, the Apricorn drive offers superior, detailed security specifications.
Form factor
The two drives differ significantly in size and portability. The Silicon Power Armor A80 is a 2.5-inch drive. It measures 5.49 inches in length, 3.7 inches in width, and 0.71 inches in height. It weighs only 9.52 ounces. The Apricorn Aegis Padlock DT is much larger. It measures 7.25 inches in length, 4.5 inches in height, and 1.5 inches in width. It weighs 2.5 pounds. The Silicon Power drive is far more portable and easier to carry. The Apricorn drive is bulkier and likely intended for stationary use rather than travel.
Hardware interface
Both drives utilize USB connectivity for data transfer. The Silicon Power Armor A80 supports USB 3.1 Gen 1, which is backward compatible with USB 3.0 and USB 2.0. It is described as SuperSpeed. The Apricorn Aegis Padlock DT uses a USB 3.0 interface. In practice, USB 3.1 Gen 1 and USB 3.0 offer similar maximum theoretical transfer speeds. Both drives provide plug-and-use functionality without requiring an external adapter. You will experience comparable data transfer rates with either drive, as both rely on standard USB 3.0 class speeds.
Storage capacity
Both the Silicon Power Armor A80 and the Apricorn Aegis Padlock DT offer 2TB of storage capacity. This is the standard size for this comparison. The Silicon Power drive is available in variations including 1TB, 4TB, and 5TB options. The Apricorn drive is available in larger variations, including 4TB, 6TB, 8TB, 10TB, 12TB, and 16TB options. While the base comparison is equal at 2TB, the Apricorn brand offers a wider range of higher capacities if you need more space in the future.
