Now that you've become somewhat accustomed to what PromoLocker has to offer, we're going to take a look at one of the firm's advanced custom flash drives; the U35-Metallic Drive. PromoLocker send over four samples with a capacity of 4GB, they were all housed in little plastic pockets which also included lanyards.
Below is a look at the custom U35-Metallic Drive from PromoLocker with the DV Hardware logo laser engraved. The drives has a polished chrome surface, which is hard to photograph. In real they look a lot better than on the picture.
Here's a closer look at the laser engraving. The flash drive was well made and I can't really find anything to complain about.
The back of the drive was engraved with DV Hardware's web address:
The drive has a removable cap and also a key ring attachment, below you can see it with the lanyard attached.
Besides the looks, we're also interested in the performance of the custom USB drives.
As usual, I first test the drives in HD Tach. This tool tests the average and burst read speeds of various sections of the drive. The drives I received had an average read speed of 17.6MB/s and burst read speed of 19.1MB/s.
Next up is the ATTO benchmark, this tool tests how fast the drive can read and write blocks of data, with sizes ranging from 1KB to 1MB. When transferring larger files, the drive achieved a read speed of 18.96MB/s and a write speed of up to 6.96MB/s.
The drives aren't as fast as the latest high-performance USB drives from firms like Corsair, OCZ and SanDisk, but they aren't slow either. For promotional drives the performance is definitely sufficient.
