Samsung vs iStorage SSD Specs
Interface type
The Samsung 860 EVO uses a SATA III interface, which connects internally via a 6 Gb/s link. This standard interface is designed for direct motherboard connection within a desktop or laptop chassis. In contrast, the iStorage diskAshur2 relies on USB 3.2 connectivity. This external interface allows for easy plug-and-play operation with any device featuring a USB port, including Windows, macOS, Linux, and Android systems. The Samsung drive requires internal mounting, while the iStorage unit offers flexible external connectivity for portable use cases.
Form factor
You must consider how each drive fits into your setup. The Samsung 860 EVO comes in a standard 2.5-inch form factor, measuring 3.94 inches in length, 2.76 inches in width, and 0.27 inches in height. This size is compatible with most internal drive bays and laptop slots. The iStorage diskAshur2 is a portable external drive, measuring 4.72 inches in length, 3.15 inches in width, and 0.59 inches in height. Its larger, ruggedized casing is built for transport rather than internal installation, making it unsuitable for standard internal drive bays but ideal for carrying data externally.
Transfer speed
Performance differs significantly between these two models. The Samsung 860 EVO delivers sequential read speeds up to 550MB/s and write speeds up to 520MB/s. These figures represent the theoretical maximums for SATA III connections. The iStorage diskAshur2 offers sequential read speeds up to 361MB/s and write speeds up to 358MB/s via USB 3.2. While the iStorage drive is fast for an external USB device, the Samsung internal drive provides higher raw throughput numbers due to the efficiency of the direct SATA connection over the USB bridge used by the portable unit.
Security features
Data protection is a key differentiator here. The iStorage diskAshur2 includes dedicated hardware security, featuring AES-XTS 256-bit hardware encryption and password protection via a 7-15 digit PIN. It also incorporates a Common Criteria EAL 5+ certified secure microprocessor, ensuring data remains encrypted even if the drive is lost or stolen. The Samsung 860 EVO offers AES 256-bit hardware encryption compliant with TCG Opal and IEEE 1670 standards. However, it lacks the dedicated PIN entry mechanism and the specific EAL 5+ certification found in the iStorage model, making the iStorage drive superior for physical security requirements.
Storage capacity
Capacity options vary between the two brands. The Samsung 860 EVO is available in sizes ranging from 250GB to 4TB, with the specific model listed being 500GB. This capacity is sufficient for many operating systems and application needs. The iStorage diskAshur2 is shown here as a 1TB model, with variations available up to 16TB. For users needing more than 500GB of portable storage, the iStorage option provides a higher baseline capacity in this comparison. The Samsung drive offers more granular lower-capacity choices, while the iStorage drive scales up to much larger sizes for extensive media libraries.
Choose based on speed and security needs
You need fast internal storage for desktop upgrades
The Samsung 860 EVO connects via SATA III for internal installation. It delivers sequential read speeds up to 550MB/s and write speeds up to 520MB/s. This interface suits users building or upgrading a desktop or laptop who prioritize raw performance and low latency over portability.
You require portable drives with hardware encryption
The iStorage diskAshur2 offers AES-XTS 256-bit hardware encryption without software. It features a password-protected microprocessor and IP56 dust and splash resistance. This model suits users who need to transport sensitive data securely across different devices while maintaining compliance with regulations like GDPR and HIPAA.
You need a rugged drive for field work
This portable SSD is built for durability with an IP56 certification against dust and water. It connects via USB 3.2 and includes a secure microprocessor. Users working in varied environments benefit from its rugged design and the ability to lock data with a PIN code.
