Why an external SSD beats an external HDD
Traditional 2.5" external HDDs are limited to about 100-130 MB/s in real-world transfers and are vulnerable to drops. An M.2 NVMe enclosure has no moving parts, runs at 800-1,000 MB/s on USB-C 10 Gbps, and survives the kind of bag-rummaging that kills mechanical drives. The price gap is shrinking every year — and this enclosure makes it affordable to go SSD.
How to assemble
Slide off the aluminium cover. Insert your M.2 SSD into the slot at 30° and lock with the included screw or rubber clip. Apply the included thermal pad over the controller. Replace the cover, plug in via USB-C, and format the drive in Windows Disk Management or macOS Disk Utility. Browse matching RAM upgrades for matching SSDs.
Pro tip — apply the thermal pad
Some enclosures ship with a small thermal pad inside the cover. Peel the protective film off both sides and place it directly over the SSD's controller chip before closing the cover. Skipping this step means your enclosure will throttle within 5-10 minutes of sustained transfer; with the pad in place, you can sustain 850-900 MB/s for hours.

Frequently asked questions
What's the actual speed I'll see?
On a USB-C 10 Gbps port with an NVMe SSD, expect 850-1,000 MB/s real-world sustained read/write. On older 5 Gbps USB-A ports it tops out around 420 MB/s — still 4x a traditional external HDD.
Does it work with my Android phone or iPad?
Yes — modern Android phones (USB-C, Android 12+) and iPad Pro (USB-C, M-series) recognise the drive as external storage. You can even record 4K video directly to it.
Does it overheat under sustained writes?
The aluminium body acts as a heatsink. Large writes (50+ GB sustained) may warm to 60-65°C but the enclosure throttles before any damage occurs. For best thermals, use the included thermal pad.
Will my existing M.2 SSD fit?
Most 2280 NVMe or SATA SSDs fit. If in doubt, WhatsApp 0314 4000131 with the model number and we'll confirm before you order.
Does it support Time Machine or Windows Backup?
Yes — formatted as APFS (Mac) or exFAT (cross-platform) it works with all major backup tools.
Can I use it with a PS5 or Xbox?
PS5 will recognise it for PS4 games and media storage. Xbox Series X/S supports it for game storage. Not for high-speed PS5 games.
Is it compatible with USB 2.0 ports?
Yes, but speed drops to ~35 MB/s. Works fine for everyday file transfers.
