The U365 uses BiCS FLASH™, stacked 3D flash memory with higher areal density than conventional 2D NAND flash memory.
 
There are four options available, with 32, 64, 128, and 256 GB of storage [3] The 256GB model can store approximately 5 hours of 4K video [4] Alternatively, the 256GB model can store 715 five-minute songs of 192kHz/24-bit high-resolution audio [5].
 
Sandrine Aubert, Senior Marketing Manager at Toshiba Memory Europe GmbH, states: "BiCS FLASH™ technology allows us to increase capacity to 256 GB, and the U365 boasts a maximum read speed of 150 MB/s. Therefore, with the U365, we can offer both speed and capacity in a stylishly designed flash drive.".
 
The U365's sleek design features a matte black finish with no embellishments for a subtle and sophisticated feel. Its capless design utilizes an intuitive retractable USB Type-A interface, compatible with USB 2.0 (High Speed) and USB 3.0 (Super Speed). It measures approximately 55 x 21.4 x 8.5 mm, excluding its sliding tab, and weighs approximately 9 g.
 
Supported operating systems include Windows 7, 8.1, and 10, and OS X v10.9–10.11, macOS v10.12–10.13. The U365 will be available starting in April 2018.
 
Grades:
 
[1] Capacity is based on installed flash memory and not user-available memory, as some memory is used for management functions. Usable capacity (available user area) is approximately 230.4 GB (1 GB = 1,073,741,824 bytes).
 
[2] 1 MB/s is calculated as 1,000,000 bytes/s. This value is the best value obtained in a specific test environment at Toshiba Memory Corporation, and Toshiba Memory Corporation does not guarantee the read speed used on individual devices. Read speed may vary depending on user specifications, such as the devices used and the size of the file being read. Write speed is lower than read speed.
 
[3] Part of the memory is used for management functions, and therefore the capacity is based on the installed flash memory and not the memory available to the user. The usable capacity (available user area) is approximately 230.4 GB (256 GB device), 115.2 GB (128 GB device), 57.6 GB (64 GB device), and 28.8 GB (32 GB device). (1 GB = 1,073,741,824 bytes).
 
[4] Calculated assuming the single video file is recorded at 100Mbps (Approximate playback time that can be stored). Actual playback time depends on the video device, resolution, and compression rate. 1 Mbps = 1,000,000 bps.
 
[5] Calculated assuming each song is five minutes long and recorded as an uncompressed 192 kHz/24-bit stream. Since the file size depends on the high-resolution audio format, the number of songs that can be stored on a USB flash drive depends on the audio format used.
