Capacity and purpose
The MemoStone ZS301-2TB is a 2TB portable SSD built for users who need fast external storage in a compact form. It suits creative professionals and everyday users moving large media libraries between Windows, Mac and Android devices. Buyers who need more than 2TB of capacity or who rely on iPhone connectivity should look elsewhere.
Speed envelope and headroom
Sequential reads reach up to 2000 MBps and writes up to 1800 MBps, while 4KB random performance hits 32000 IOPS read and 210000 IOPS write. That throughput handles 4K video editing, game libraries and bulk backups comfortably; sustained heavy workloads will eventually hit the thermal ceiling of the zinc-alloy casing and the 2.6W active power draw.
USB 3.2 Gen 2x2 practical limits
The drive uses a USB 3.2 Gen 2x2 Type-C connection rated at 20Gbps, so real-world speed depends on the host port supporting that exact standard. On MacBook models the transfer rate may drop below the advertised ceiling, and the interface cannot exceed its 20Gbps electrical limit regardless of the controller.

Questions about this item
Will the USB 3.2 Gen 2x2 interface work with my older USB 3.0 ports?
Yes, the drive is backward compatible and will operate at the speed of the older port.
How can I verify the drive is delivering the rated 2000 MBps read speed after setup?
Run a benchmark tool such as CrystalDiskMark to confirm sequential read performance approaches the 2000 MBps figure.
Does the package include a USB-C cable or must I purchase one separately?
A USB-C cable is included in the box for immediate plug-and-play use.
