BEST SSDs! Samsung T7 vs SanDisk vs Crucial X8


In the quest for the perfect portable storage solution, solid-state drives (SSDs) have become the preferred choice for many due to their speed, durability, and form factor. With an abundance of options in the market, it’s tough to determine which SSD will best suit your needs. To make your decision easier, I’ve undertaken the task of testing five of the most popular SSDs: the Samsung T7, SanDisk Extreme and Portable, Crucial X8, and the Acasis hub with a high-performance Sabrent card. In this article, we’ll delve into technical comparisons and real-world performance tests to help you choose the best SSD for your requirements.

Technical Comparison

The SSDs were put through a series of tests using various devices and operating systems to evaluate their performance in real-world scenarios. These tests included sequential and random read and write operations with larger files. Below is a table summarizing the key features and performance metrics of each drive:

SSD Model Capacity Advertised Speed (Max) Real-world Performance
SanDisk Extreme 2TB 1050MB/s Varies by device, overall solid performance
SanDisk Portable 1TB 520MB/s Lower than advertised in large file transfers
Samsung T7 1TB 1050MB/s Highly variable, but excellent with Tab S8 Ultra
Samsung T7 Shield 1TB 1050MB/s Twice as fast as some, with good durability
Crucial X8 1TB 1050MB/s Best overall performance in tests
Acasis Hub w/ Sabrent card Customizable Dependent on card Top-notch, upgradeable, and flexible

Real-world Performance and Observations

During testing, it was noted that the performance of these SSDs could vary significantly between different devices. For instance, the SanDisk Extreme and Samsung T7 Shield performed differently on the M2 iPad Pro compared to the M1 iPad Pro and the Tab S8 Ultra. It was also interesting to see that the speeds advertised by manufacturers did not always align with the real-world transfer speeds, emphasizing the importance of independent testing.

The Crucial X8 stood out with its impressive performance in sustained transfers and its ability to remain cool during operations, likely due to its aluminum body and potential internal cooling mechanisms. Meanwhile, the Samsung T7 Shield offered rugged durability with drop protection and an IP65 rating.

Bonus Options: High-Performance Solutions

For those looking for more than just a portable SSD, I also tested some “nuclear” options. The Acasis hub, in particular, is not just an external SSD enclosure but also a versatile hub with HDMI and other ports, allowing for easy upgrades and swaps of the SSD card. These high-performance solutions are excellent for intensive work such as graphic design, photo editing, and video editing directly from the SSD.


Choosing the right SSD depends on your specific needs, whether it’s for general storage, rugged outdoor use, or high-performance work. The Crucial X8 emerged as a top performer in this roundup, providing excellent speed and value. However, if durability and extra features are a priority, the Samsung T7 Shield is a compelling option.

Always remember to go beyond the advertised speeds and consider real-world performance when selecting an SSD. And for those needing more from their external storage, the Acasis hub with a high-quality SSD card provides a potent and flexible solution.
