Magnetic Portable SSD
The DATO ARES Q4 is a 2 TB external solid-state drive that attaches magnetically to iPhone 15 Pro and newer models. Its MagSafe-compatible connection removes the need for cables during mobile recording or file offload. The drive weighs 40 grams and measures 64 by 64.3 by 12 millimetres, making it pocketable for field work.
Speed and Capacity Headroom
Sequential reads reach 4000 MBps and writes reach 3600 MBps over the USB 3.2 Gen 2x2 interface, so large ProRes libraries move in seconds. The 2 TB capacity holds hours of 4K HDR footage before a transfer is required. Sustained write performance can become the limiting factor during very long, high-bitrate takes.
Direct 4K ProRes Recording
The decisive specification is the ability to record 4K ProRes HDR video straight to the drive from a compatible iPhone. This eliminates an intermediate copy step and keeps internal phone storage free. Buyers who do not shoot ProRes on a supported iPhone will not use this core capability.

Questions about this item
Will the USB 3.2 Gen 2x2 interface on the ARES Q4 run at full speed when plugged into an older USB 3.2 Gen 2x1 port?
The drive will work but speeds drop to the older port's 10 Gbps limit, so you lose the 4000 MB/s read and 3600 MB/s write potential.
How can I confirm the ARES Q4 is delivering its rated 4000 MB/s read and 3600 MB/s write after setup?
Run a benchmark tool such as CrystalDiskMark or Blackmagic Disk Speed Test over the USB-C cable; sequential results should approach the stated figures on a USB4 or USB 3.2 Gen 2x2 host.
What comes in the box with the 2 TB ARES Q4 and do I need to buy any extra cables for USB-A hosts?
The package includes a 40 Gbps USB-C to C cable and a 10 Gbps USB-C to A adapter, so no extra purchase is required for either port type.
