How alternatives compare to Apricorn
iStorage diskAshur PRO2 8TB Encrypted SSD
The iStorage diskAshur PRO2 offers similar FIPS certification and 8TB capacity in a slightly lighter package. It weighs 7.94 ounces, which is less than the Apricorn drive. This model uses a graphite finish and measures 0.79 inches thick. You get hardware encryption and password protection alongside FIPS validation. The main difference is the interface and specific certification level. While the Apricorn drive uses USB 3.0, this iStorage unit provides a rugged portable solution for sensitive data. It is a strong alternative if you prefer a lighter form factor without sacrificing security standards. The slightly smaller dimensions may fit better in compact bags. You should choose this if you need certified security with a more portable design.
iStorage diskAshur PRO3 8TB Encrypted SSD
The iStorage diskAshur PRO3 updates the security standards to FIPS 140-3 Level 3. This newer certification may be required for specific modern compliance needs. It retains the 8TB capacity and hardware encryption found in the Apricorn drive. The design is similar, measuring 5.16 inches in length. It uses PIN-based access control for authentication. You lose the separate admin and user modes present in the Apricorn model. Instead, you get a streamlined PIN entry system. This drive is ideal if your organization mandates FIPS 140-3 compliance. The Emerald Green color option adds visual distinction. It is a direct competitor for users who need the latest security validation in a portable SSD format.
iStorage diskAshur2 8TB Secure Portable SSD
The iStorage diskAshur2 provides rugged durability with a fiery red exterior. It maintains the 8TB capacity and hardware encryption but lacks FIPS validation. This makes it a budget-friendly option for those who do not need government-level certification. The drive uses PIN authentication for security. It is slightly lighter than the Apricorn drive at 7.62 ounces. The form factor is similar, making it easy to carry. You give up the FIPS 140-2 Level 3 validation found in the original. This is a practical choice for professionals who prioritize physical toughness and simple PIN access over strict compliance standards. It is suitable for general secure storage needs without the premium cost of certified drives.
iStorage diskAshur M2 240GB Encrypted Portable SSD
The iStorage diskAshur M2 is a compact 240GB drive, significantly smaller than the 8TB Apricorn model. It is designed for users with small data volumes who need portability. The drive features hardware encryption and FIPS validation. It measures 1.77 inches wide and 0.47 inches thick. This makes it much easier to carry than the larger 8TB units. You sacrifice capacity and the rugged external casing of the Apricorn drive. This model is ideal for carrying sensitive documents or small datasets. It is not suitable if you need to store large media files or extensive databases. Choose this if you prioritize extreme portability and compliance over storage space.
Mushkin Gamma 8TB PCIe 4.0 NVMe SSD
The Mushkin Gamma 8TB is an internal NVMe SSD, not a portable drive. It uses a PCIe 4.0 interface and M.2 2280 form factor. This drive is designed for PS5 and PC internal storage expansion. It offers high-speed performance for gaming and computing tasks. You lose the portable form factor and USB connectivity of the Apricorn drive. There is no external hardware encryption or FIPS validation. This is a raw storage solution for internal system upgrades. It is best for users who need fast internal storage for gaming or professional workloads. It does not replace the secure, portable nature of the Apricorn drive. Choose this if you are building a PC or upgrading a console.
iStorage diskAshur3 8TB Encrypted SSD
The iStorage diskAshur3 offers FIPS 140-3 Level 3 compliance with 8TB capacity. It features hardware encryption and password protection. The drive is available in an Emerald Green color. It measures 5.16 inches in length and 0.82 inches thick. This model provides robust security for users needing the latest compliance standards. You get a PIN-based access system for authentication. The drive is similar in size to other iStorage 8TB models. It is a strong alternative if your organization requires FIPS 140-3 certification.
