Tianken Ultra Slim 750GB
Score: 70/100
Aocesk 2TB Portable SSD
Score: 80/100Rankings

The Aocesk Portable Mobile SSD is an aluminum enclosure for M.2 SATA SSDs, offering up to 2 TB (or user-installed up to 4 TB) of storage with USB 3.1 connectivity and smart hibernation. While its build quality and flexibility are strong points, the lack of NVMe support and modest USB-3.0 speeds limit its appeal for high-performance users.

The Tianken 750 GB Ultra Slim Portable HDD offers a thin, lightweight design with broad OS and console compatibility at a budget price. Performance is limited to typical 5400 RPM HDD speeds and it lacks advanced security or rugged features.

Professional reviewers would categorize the Tianken drive as a budget-tier external HDD, praising its low cost, thin profile and long warranty, but criticizing its lack of SSD performance, plastic construction and absence of security features, making it suitable for casual storage rather than demanding professional workflows.
Everyday users generally appreciate the drive's portability, ease of use and price, especially for gaming consoles and photo backups, while recurring frustrations revolve around the reduced usable capacity, the need to reformat for Mac, modest transfer speeds and concerns over the cheap plastic housing.

Professional reviewers view the Aocesk enclosure as a niche, DIY-focused product; its aluminum construction and smart hibernation are modest strengths, but the USB 3.0/3.1 interface and lack of NVMe support are major drawbacks compared to modern portable SSDs.
Everyday users praise the slim metal design, plug-and-play ease, and ability to reuse existing M.2 SATA SSDs, while complaining about confusion over it being an enclosure only and the slower-than-expected transfer rates.
“Works perfectly with my PS4 and laptop.”

“Very thin and light - fits in my pocket.”

“Great value for the price.”
