How each alternative compares
iStorage diskAshur PRO2 256GB Secure SSD
The iStorage diskAshur PRO2 256GB Secure SSD offers FIPS Level 3 validation, which is a higher security standard than the Apricorn’s Level 2. It provides slightly more storage capacity at 256GB compared to the Apricorn’s 240GB. However, it is significantly larger and heavier. The iStorage unit measures 4.88 inches long and weighs 7.9 ounces, whereas the Apricorn is compact at 3.25 inches and 1.6 ounces. You should choose the iStorage if you need stricter certification and do not mind the extra bulk. The Apricorn remains better for users who prioritize a lighter, more portable form factor while still needing ruggedized encrypted storage.
Apricorn Aegis Fortress L3 8TB Encrypted SSD
The Apricorn Aegis Fortress L3 8TB Encrypted SSD is designed for high-capacity needs, offering 8TB of storage compared to the original’s 240GB. It also features FIPS validation for secure data protection. This drive is much larger, measuring 4.75 inches long and weighing 1 pound, making it less portable than the 1.6-ounce Apricorn Aegis Padlock. You should pick this alternative if you need substantial space for large files and can accommodate a heavier device. The original Apricorn is the better choice if you require a compact, lightweight drive for on-the-go use where carrying a one-pound unit is impractical.
iStorage diskAshur M2 240GB Encrypted Portable SSD
The iStorage diskAshur M2 240GB Encrypted Portable SSD matches the original’s 240GB capacity but differs in physical design. It is wider at 1.77 inches and longer at 4.37 inches, weighing 9.52 ounces. This makes it considerably heavier than the 1.6-ounce Apricorn Aegis Padlock. Both drives offer FIPS validation and hardware encryption. You should consider the iStorage if you prefer its specific ruggedized form factor or brand preference. The Apricorn remains the superior option for users who need a drive that is virtually shock-resistant, silent, and highly portable due to its significantly lower weight and compact dimensions.
iStorage diskAshur PRO3 512GB Hardware-Encrypted SSD
The iStorage diskAshur PRO3 512GB Hardware-Encrypted SSD provides double the storage capacity of the original Apricorn drive, offering 512GB versus 240GB. It also features FIPS Level 3 validation, which is a higher security tier than the Apricorn’s Level 2. However, it is much larger and heavier, measuring 5.16 inches long and weighing 1.21 pounds. The Apricorn is only 1.6 ounces. You should choose the iStorage if you need more space and stricter certification standards. The original Apricorn is better for those who prioritize extreme portability and a rugged, lightweight design over maximum capacity or higher security validation levels.
