JETFLASH600 The key is scheduled for transfer 18MB / s write and 32MB / s read (see picture product packaging). Upon receipt of the package, the packaging of the TRANSCEND key does already announced that more than 16MB / s for writing! The product is however well in line with other images. For cons, the tests were somewhat disappointing for ULTRASPEED key as many utilities as RAW in Windows, Linux or Mac, demonstrate a write speed of 8.71MB / s (half the announced) and 29.10MB / s reading. The gap remains huge in writing so I, having checked the product via the serial number, contacted Trancend technical support in order to have explanations (manufacturing fault?). While awaiting an official response from TRANSCEND, this USB key is really 32GB Lifetime Warranty (Limited Warranty 100 years), and as such remains a bargain compared to products a warranty or years.
