ADATA SE920 Buyer’s Guide
Next-Gen USB4 Speed for Creators and Gamers
USB4 3800MB/s Speed | Active Fan Cooling | External Gaming Storage
Introduction
If you’ve been hunting for the absolute fastest external storage on the market, you’ve likely stumbled across the ADATA SE920. This isn't your average portable drive; it is one of the very first consumer SSDs to utilize the USB4 interface, promising speeds that leave traditional USB 3.2 drives in the dust.
This drive is built for a specific audience: creative professionals moving massive 4K video files, gamers who need a high-speed portable library, and tech enthusiasts who want to leverage the Thunderbolt 4 or USB4 ports on their high-end laptops. As a PCIe Gen 4.0 drive housed in a next-gen enclosure, the SE920 sits at the very top of the external storage hierarchy, bridging the gap between portable convenience and internal NVMe performance.
Product Overview: What is the SE920?
While most portable SSDs are simple sealed boxes, the ADATA SE920 is a piece of engineering. It functions as an external enclosure housing a high-performance M.2 2280 PCIe Gen 4.0 SSD.
The magic here lies in the bridge chip. The SE920 utilizes the ASMedia ASM2464PD controller, which enables the drive to communicate via the USB4 protocol (tunneling PCIe traffic). This allows it to bypass the traditional 10Gbps or 20Gbps bottlenecks of older USB standards. Internally, ADATA typically uses high-quality 3D TLC NAND, ensuring that the drive offers the durability and sustained performance needed for heavy write workloads, unlike cheaper QLC-based alternatives.
Performance & "Real World" Speed
The ADATA SE920’s primary selling point is raw throughput.
Sequential Read: Up to 3,800 MB/s
Sequential Write: Up to 3,700 MB/s
To put this in perspective, a standard SATA SSD tops out at 550 MB/s, and a typical portable NVMe drive (USB 3.2 Gen 2) hits around 1,000 MB/s. The SE920 is nearly 4x faster than the average portable SSD.
What does this mean for you?
For Gamers: You can move a 100GB game installation from your PC to the drive in under 30 seconds.
For Creators: If you edit video directly off the drive, scrubbing through 4K or 8K footage is buttery smooth. The bandwidth is high enough that it feels indistinguishable from an internal drive for most workflows.
File Transfers: Backing up a 1TB project file takes roughly 4–5 minutes, assuming your computer has a USB4 or Thunderbolt 4 port to support the speed.
Thermal Management: The "Breathing" Case
Heat is the enemy of performance, especially for Gen 4 NVMe drives running at these speeds. If a drive gets too hot, it throttles (slows down) to protect itself.
The SE920 features a unique patented active cooling system. The casing of the drive is extendable. When you push down on the housing, the chassis expands, opening air vents and activating a tiny built-in micro fan.
Closed Mode: Silent, passive cooling (fine for light tasks).
Open Mode: Active cooling with the fan engaged.
ADATA claims this reduces temperatures by up to 10°C compared to fanless designs. For sustained writes—like transferring a terabyte of footage—leaving the case "open" is highly recommended to maintain peak transfer rates.
Compatibility: PC, PS5 & Consoles
Crucial Clarification: While the SE920 is an NVMe drive internally, it is sold as an external USB unit.
PlayStation 5 Compatibility The ADATA SE920 IS compatible with the PS5, but with an important distinction: it functions as External USB Extended Storage.
You can play PS4 games directly from it.
You can store PS5 games on it (cold storage) to free up space on your console.
You cannot play PS5 games directly from this drive (PS5 games require an internal M.2 installation).
Note on Cooling: Because this is an external unit with its own fan, you do not need to buy a separate heatsink.
Xbox Series X/S The SE920 works as external media storage for playing older Xbox One titles or storing Series X/S games. However, like the PS5, it cannot play Series X/S optimized titles, which require the proprietary Seagate or WD expansion cards.
PC & Mac This is where the drive shines. To get the advertised 3800 MB/s, your PC must have a USB4 or Thunderbolt 4 port. It is backward compatible with USB 3.2 and USB 2.0, but speeds will drop to match the slower port (usually 1000 MB/s or 500 MB/s).
Strengths & Weaknesses
Pros:
Class-Leading Speed: One of the few drives capable of 3,800 MB/s over USB.
Innovative Cooling: The extendable case and micro-fan effectively manage heat during heavy loads.
Future-Proof: Ready for the USB4 ecosystem.
Build Quality: Solid metal construction feels premium and durable.
Cons:
Fan Noise: When the case is open and the fan is spinning, there is a slight audible whir (unlike silent passive drives).
Port Dependent: You pay a premium for speed you can't use if your laptop lacks USB4/Thunderbolt.
Bulkier: Due to the cooling mechanism, it is physically larger than competitors like the Samsung T7.
Verdict: Should You Buy It?
The ADATA SE920 is a niche product for users who refuse to compromise on speed.
Buy this if:
You are a video editor or content creator who needs to edit directly from an external drive on a laptop with Thunderbolt 4/USB4.
You frequently transfer massive files (100GB+) and want to minimize downtime.
You want the fastest possible external "cold storage" for your game library.
Skip this if:
You primarily need a drive for a PlayStation 5 internal upgrade (Buy the ADATA XPG GAMMIX S70 Blade instead).
Your computer only has standard USB 3.0 ports (You won't get the speed benefits you're paying for).
You prioritize silence over maximum sustained performance.
If you have the hardware to support it, the SE920 offers a glimpse into the future of external storage, delivering desktop-class performance in your pocket.
