Pros

✓ Four physical connectors (USB-C, iPhone, Micro USB, USB-A) with no adapters to lose

Manufacturer description

The ZARMST 256GB flash drive solves the recurring "Storage Almost Full" problem on iPhone without forcing you into a cloud subscription. Its 4-in-1 body carries four physical connectors - USB-C, an iPhone port, Micro USB, and standard USB-A - so you can pull photos off a phone and drop them onto a laptop, TV, or car audio system without hunting for an adapter. The aluminum frosted housing keeps the connectors rigid where flexible dongle-style drives tend to work loose. ZARMST rates the drive at up to 80MB/s read and 30MB/s write, which is workable for offloading a camera roll or a batch of…

Frequently Asked Questions

Will this work with my iPhone without an adapter?

Yes. The drive has a built-in iPhone port as one of its four connectors, alongside USB-C, Micro USB, and standard USB-A, so no separate adapter is needed.

How fast does it transfer files?

ZARMST rates it at up to 80MB/s read and 30MB/s write. Actual speed varies based on your host device, the interface you plug into, and usage conditions.

Do I need to install an app to use it on iOS?

For iOS file management ZARMST provides the easyflash pro app from the App Store, which handles viewing, one-click album and contact backup, and encrypted files.

Why does my device show less than 256GB of space?

Storage brands calculate 1GB as 1000MB while computers read 1GB as 1024MB, so the reported capacity is lower than the labeled 256GB. This is normal for all flash drives.

Can I use it with Android phones and my laptop too?

Yes. It supports Type-C and older Micro USB Android phones, plus laptops, tablets, TVs, and car audio systems through the standard USB-A connector.
