Four SSDs in one fast enclosure.
Before you order: how it fits, how to set it up and whether it works with your laptop.
-
Will it fit? Four M.2 NVMe SSDs, 2230 to 2280
More detail
Will my SSDs fit?
NVMe M.2 SSDs with M-key fit, in sizes 2230 to 2280 and up to 8 TB per SSD. You can fit up to four SSDs. NVMe is the fast type of M.2 SSD; your SSD's specifications tell you which type you have. A SATA M.2 SSD does not work.
-
Easy to set up? SSDs in, adapter and cable in
More detail
Can I set it up myself?
You slide the tray out of the enclosure, place your SSDs and secure them with the silicone plugs; you need a small screwdriver for that. Then you connect the power adapter first and then the USB-C cable. You don't need drivers. Each SSD appears as its own drive; you combine them with software RAID on your computer, further down you can see how.
-
Your laptop? Full speed on USB4
More detail
Will it work with my laptop?
It works on Windows, macOS, Linux and Android. You get full speed, up to about 3000 MB per second with several fast NVMe SSDs together in software RAID, on a 40 Gbps USB4 port. On a 10 Gbps port you get around 1050 MB per second.

Cooling

Heatsink and fan carry the heat away
More detail
How the heat gets out
The thermal pad sits between your M.2 SSD and the aluminium heatsink and passes the heat on. The cooling fins of the heatsink release that heat into the air, and the fan in the rear cap blows the warm air out.
Place the enclosure on a hard, flat surface and do not cover the ventilation openings.

Speed in practice
With several fast NVMe SSDs together in software RAID you reach up to about 3000 MB/s, on a USB4 port of 40 Gbps and with the cable that comes with it. One SSD reaches up to 16 Gbps. It also works on a USB 3.2 Gen 2 port of 10 Gbps, at around 1050 MB/s. What you actually get depends on your SSDs and your port.

Software RAID
You combine SSDs on your computer
The enclosure has no RAID chip: by default, each SSD appears as its own drive. With software RAID on your computer, you combine SSDs into one drive.
Up to about 3000 MB/s with several fast NVMe SSDs together in software RAID on a 40 Gbps USB4 port.
How to set it up
Windows 10 and 11
Storage Spaces
- Type Storage Spaces in the search box on the taskbar and open it.
- Create a new storage pool and select the SSDs you want to combine.
- Create a storage space in that pool and follow the steps. Windows shows it as one drive.
Mac
Disk Utility
- Open Disk Utility and choose RAID Assistant from the File menu.
- Select the SSDs you want to combine and follow the steps of the assistant.
- Give the set a name and create it. Your Mac shows it as one drive.
Or four separate drives (default)
If you set nothing up, each SSD appears as its own drive. You don't need any software for that.
- Creating software RAID erases all data on those SSDs. So do it before you store files.
- Software RAID is not a backup: keep important files somewhere else too.
- A software RAID set only works on the system you create it on: Windows and Mac cannot read each other's sets.
- Keep all SSDs of the set in the enclosure and keep the enclosure connected.
- Preferably use identical SSDs of the same size.

What do you use it for?
Edit video and photos
Work directly from the drive in your editing or photo software. Heatsink and fan keep the SSDs cool, even on long transfers.
Your archive in one place
Keep your photo and video archive together, on separate drives or combined with software RAID. Software RAID is not a backup: keep important files elsewhere too.

Frequently asked questions
Will my M.2 SSDs fit?
Every M.2 NVMe SSD with M-key fits, in the lengths 2230, 2242, 2260 and 2280, up to 8 TB per SSD. You can fit up to four SSDs; you do not need to fill all four bays. If the label says NVMe or PCIe, you have the right type. Not sure? Check “Which M.2 do I have?” above first.
Does a SATA M.2 SSD work?
No. This enclosure only works with M.2 NVMe SSDs with M-key. A SATA M.2 SSD has two notches in the gold edge and does not work, just like B-key, mSATA, 2.5 inch drives and SSDs longer than 80 mm.
How do I set up software RAID?
The enclosure has no RAID chip: by default, each SSD appears as its own drive. With software RAID on your computer you combine SSDs into one drive: on Windows 10 and 11 with Storage Spaces, on a Mac with Disk Utility. Creating it erases the data on those SSDs, and software RAID is not a backup.
Which port do I need?
A USB-C port that transfers data. On a 40 Gbps USB4 port, several fast NVMe SSDs together in software RAID reach up to about 3000 MB/s; one SSD reaches up to 16 Gbps. On a 10 Gbps port you get around 1050 MB/s. A port with only a battery symbol is for charging and does not transfer data. The enclosure always needs the included power adapter.
Does the enclosure get warm?
An aluminium heatsink with 28 cooling fins rests on your SSDs via thermal pads, and a fan in the rear cap blows the warm air out. That keeps the speed up, even on long transfers. Place the enclosure on a hard, flat surface and keep the ventilation openings clear.
Are SSDs included?
No. This is an empty enclosure: you fit up to four M.2 NVMe SSDs yourself (2230 to 2280) and secure them with the silicone plugs. You need a small screwdriver for that. For software RAID, preferably use identical SSDs. No SSDs yet? Check “Which M.2 do I have?” above first, so you are sure to order the right ones.
