128 GB USB 2.0 drive for everyday files

The SanDisk Cruzer Blade provides 128 GB of storage in a compact black and red housing. It connects via a standard USB Type A plug and uses the USB 2.0 interface. The drive includes 128-bit AES encryption for basic data protection and supports Windows ReadyBoost for system caching.

Sustained write speed tops at 31 MB/s

Large transfers run at the USB 2.0 bus limit rather than the advertised burst figure. Expect consistent throughput around the rated maximum during long copies, with no thermal throttling in the small form factor. The controller maintains steady performance across the full capacity.

Plug into any USB Type A port and go

No drivers are required on modern operating systems. The tiny dimensions of 0.29 by 0.69 by 1.63 inches leave the drive protruding very little, reducing the risk of accidental knocks. A lanyard loop is moulded into the casing for a strap, though the loop is narrow and may not accept thick cords.

Questions about this item

Does the USB 2.0 interface on the Cruzer Blade generate noticeable heat when I leave it plugged in all day?

The drive uses a low-power USB 2.0 connection and has no moving parts, so it stays cool during continuous use.

What type of USB port must my computer have for the Type A connector on this 128GB drive to work?

Any standard USB Type A port — USB 2.0, 3.0 or later — will recognise the drive immediately.

Will the 31MB/s write speed of this USB 2.0 stick slow down file transfers on an older laptop that only has USB 2.0 ports?

No, the drive is designed for USB 2.0 and will deliver its rated up to 31MB/s write speed on those ports.
