For just $99.99, down from its list price of $119.99, this USB4 enclosure hits its lowest price on record. The 30-day average sits at $115.44, and the 90-day average is $116.60, so the $20 discount is a genuine cut, not a fake Prime Day markup.

If you have been waiting on an external SSD enclosure, the timing is right.

What You're Getting

The ProArt PA40SU delivers USB4 speeds up to 40 Gbps over USB-C, making it one of the faster enclosures you can pair with an NVMe SSD. It supports both 2230 and 2280 drive sizes with a tool-free push-to-open mechanism, so swapping drives takes seconds.

ASUS also includes a four-level smart cooling fan that keeps noise low during sustained transfers, plus the ProArt SSD Dashboard for real-time drive monitoring.

Who This Is For

Best for: video editors, photographers, and anyone moving large files regularly who needs USB4 transfer speeds without paying a premium. The tool-free design also makes it a solid pick for creative pros who swap SSDs between projects frequently.

Skip it if you only need a basic USB 3.2 enclosure and want to spend under $50.

Final Verdict

At $99.99. This is the cheapest the ProArt PA40SU has been, and USB4 enclosures at this price point rarely include smart cooling and a monitoring dashboard. If you need fast external storage this Prime Day. This is the price to pull the trigger on.
