One of the most impressive aspects of the SAMSUNG T7 Portable SSD is its build quality and durability. Encased in a solid aluminum unibody, the drive is designed to withstand the rigors of travel, work, and adventure. It’s rated for shock resistance up to 6 feet (1.8 meters), making it ideal for photographers, videographers, and digital nomads who work in unpredictable environments. The compact design—measuring just 2.95 x 2.28 x 0.35 inches and weighing only 2.08 ounces—makes it easy to slip into a pocket, camera bag, or laptop sleeve. Despite its small size, the T7 packs a massive 4TB capacity, offering enough space to store thousands of photos, hours of 4K video, or entire game libraries.
Security is another area where the SAMSUNG T7 Portable SSD shines. It features hardware-based AES 256-bit encryption, which protects your data even if the drive is lost or stolen. Users can set a password via the Samsung Magician software (available for Windows and macOS), and the drive will remain inaccessible without the correct credentials. This makes it an excellent choice for professionals handling sensitive data, such as legal documents, financial records, or medical files. The drive also supports automatic backup and firmware updates through the same software, ensuring optimal performance and security over time.
Versatility is a hallmark of the SAMSUNG T7 Portable SSD. It’s compatible with a wide range of devices, including PCs, Macs, Android phones, iPhones (via USB-C), PlayStation, Xbox, and even cameras that support external recording. This cross-platform support makes it a true all-rounder. Samsung highlights its ability to record Ultra High Resolution (4K 60fps) video directly to the drive, which is a game-changer for filmmakers and content creators using high-end cameras or smartphones like the iPhone 15 Pro. The drive can handle ProRes 4K at 60fps recording, eliminating the need for large internal storage on the device and enabling longer shooting sessions.
The SAMSUNG T7 Portable SSD also excels in power efficiency and thermal management. It draws power directly from the USB-C connection, requiring no external power adapter. The aluminum body acts as a natural heatsink, helping to dissipate heat during extended use and preventing throttling during large file transfers. Samsung’s Dynamic Thermal Guard technology monitors temperature and adjusts performance to maintain stability. The drive comes with both USB-C to USB-C and USB-C to USB-A cables, ensuring compatibility with older systems. It’s also backed by a 3-year limited warranty, which is standard for portable SSDs but slightly shorter than the WD_BLACK’s 5-year coverage.
Pros of the SAMSUNG T7 Portable SSD:
- Excellent portable performance: Up to 1,050 MB/s read and 1,000 MB/s write—blazing fast for an external drive.
- Rugged and compact design: Aluminum unibody with 6-foot drop protection; easy to carry.
- Advanced security: AES 256-bit encryption and password protection via Samsung Magician.

Head-to-Head Comparison
Performance: Raw Speed vs. Portable Efficiency
When it comes to raw performance, the WD_BLACK 4TB SN7100 NVMe is in a league of its own. With read speeds up to 7,250 MB/s and write speeds near 7,000 MB/s, it leverages the full bandwidth of the PCIe Gen4 x4 interface—something the SAMSUNG T7 Portable SSD simply cannot match due to its USB 3.2 Gen 2 limitation (capped at ~1,200 MB/s theoretical, ~1,050 MB/s real-world). The WD_BLACK drive is 7 times faster in sequential reads and 6 times faster in writes. This difference is most noticeable in gaming, where load times are drastically reduced, and in creative workflows, where large files (e.g., 4K video, 3D models) are processed, rendered, or exported in a fraction of the time.

However, the SAMSUNG T7 Portable SSD delivers exceptional performance for a portable drive. At 1,050 MB/s, it’s significantly faster than older USB 3.0 drives (typically 400–500 MB/s) and even many internal SATA SSDs. For everyday tasks like file transfers, photo backups, or streaming media, the T7 feels lightning-fast. Its real-world performance is further enhanced by low latency and consistent throughput, thanks to Samsung’s optimized firmware and DRAM cache. While it can’t compete with the WD_BLACK in speed, it excels in efficiency and responsiveness under typical portable use cases.
Design and Build Quality: Internal Minimalism vs. Rugged Portability
The WD_BLACK 4TB SN7100 NVMe is a minimalist M.2 2280 drive—just a circuit board with NAND chips and a controller, designed to be installed inside a device. There are no moving parts, no casing, and no cables. Its design is purely functional: compact, lightweight, and thermally efficient. However, it lacks physical protection—any damage during handling or installation could be catastrophic. It’s not meant to be handled frequently; once installed, it’s out of sight and out of mind.
In contrast, the SAMSUNG T7 Portable SSD is built like a tank. The aluminum unibody provides structural rigidity, heat dissipation, and a premium feel. The compact size and lightweight design make it perfect for on-the-go use. The shock resistance (up to 6 feet) and solid construction mean it can survive drops, bumps, and the chaos of travel. The inclusion of both USB-C to C and USB-C to A cables adds convenience, eliminating the need for adapters. For users who value durability and portability, the T7’s design is unmatched.
Use Cases: Who Should Choose Which?
The WD_BLACK 4TB SN7100 NVMe is the clear choice for gaming PCs, high-performance laptops, and handheld gaming devices. Gamers will appreciate the ultra-fast load times, seamless gameplay, and ability to store dozens of modern AAA titles. Content creators working on large projects (e.g., video editing, 3D rendering) will benefit from the high throughput, reducing render times and improving workflow efficiency. It’s also ideal for users who want to future-proof their system with PCIe Gen4 support and massive storage.
The SAMSUNG T7 Portable SSD is perfect for content creators on the move, students, professionals, and travelers. Videographers can record 4K video directly to the drive. Photographers can back up RAW files instantly. Students can carry entire lecture libraries. Business users can securely transfer sensitive data. Its universal compatibility means it works with almost any device, making it a true all-purpose external storage solution. It’s also great for backing up internal drives, expanding storage on older laptops, or using as a portable boot drive.
Value and Price: Premium Performance vs. Affordable Versatility
At first glance, the WD_BLACK 4TB SN7100 NVMe appears more expensive per GB than the SAMSUNG T7 Portable SSD, but this reflects its premium internal performance. You’re paying for the PCIe Gen4 interface, higher endurance (2,400 TBW), and the ability to integrate seamlessly into high-end systems. For users who need the absolute fastest internal storage, the price is justified.
The SAMSUNG T7 Portable SSD offers better value for portable use. It’s competitively priced for its speed, durability, and features. The inclusion of encryption, cross-platform support, and video recording capabilities adds significant value. For users who don’t need internal speeds or are upgrading older systems, the T7 provides excellent performance at a more accessible price point.
Durability and Longevity: Endurance vs. Physical Protection
The WD_BLACK 4TB SN7100 NVMe wins in endurance with a 2,400 TBW rating—ideal for heavy write workloads like gaming or video editing. The 5-year warranty also reflects long-term reliability. However, it has no physical protection and is vulnerable during installation.
The SAMSUNG T7 Portable SSD wins in physical durability with shock resistance and a rugged build. The 3-year warranty is shorter, but Samsung’s reputation for quality and the drive’s robust design suggest it will last well beyond that. The aluminum body also helps with thermal management, preventing overheating during extended use.
Software and Ecosystem: Control vs. Security
The WD_BLACK Dashboard offers deep control over the WD_BLACK 4TB SN7100 NVMe, with tools for monitoring, optimization, and firmware updates. However, it’s limited to Windows.
The Samsung Magician software for the SAMSUNG T7 Portable SSD provides encryption, password protection, and backup tools, with support for both Windows and macOS. While less granular than the WD_BLACK Dashboard, it excels in security and user-friendliness.
Frequently Asked Questions
