Hi Gictimes! USB Type-C, about which already have written in detail on GT has not yet become the most common, but manufacturers are starting to build the infrastructure.Most recently at Computex 2015, the flash drive was introduced Kingston microDuo 3C. and it’s time to evaluate its real features and performance. Here’s more details about one of the first drives USB 3.1 Type-C
I’ll start with the price. Yandex.Market says that you can buy such a drive for a little more than one thousand rubles. The price starts at from 1009 rubles If we draw analogies with "classic" flash drives, it’s easy to see that microDuo 3C will be more expensive than regular 2.0 drives and lower in price than high-speed 3.0 devices.
Traditionally a couple of words about the packaging. Transparent plastic blister, absolutely standard type of USB drives delivery. Inside, except the flash drive itself there is a small strap for fixation on the key ring or key chain.
Dual-interface flash drives are nothing new, Kingston has options with microUSB, and both support USB 2.0 as well as USB 3.0 Now it’s the turn of the new USB 3.1 Type C interface.
The positioning of the USB Type C standard itself assumes the use of drives with mobile devices and the transfer of data to conventional computers. The new Apple MacBook is not yet widespread, many manufacturers are in no hurry to release updated devices (although there are already devices from Google and Nokia).
The following specifications are claimed for the Kingston microDuo 3C :
- Storage capacity : 16, 32 or 64 gigabytes
- Standards Support : USB 2.0, 3.0, 3.1
- Reading Speed : up to 100MB/s
- Write Speed : up to 10 MB/s (for 16 GB), up to 15 MB/s (for 32 GB and 64 GB)
- Warranty Period : 5 years
For testing I had to specially rearrange the test bench, which now is a bit different from the one I usually use. The thing is that the new interface has not yet received the proper distribution, and the only available motherboard in Russia was MSI Z97A Gaming 6 The ASMedia ASM1142 controller is unsoldered on it, which provides support for USB 3.1 Gen 2 interface (up to 10Gb/s)
- Processor : Intel Core i7-4790S
- Motherboard : MSi Z97A Gaming6
- RAM : Kingston HyperX Predator DDR3-2800 2*4 Gb
- System SSD drive : HyperX Predator PCI-E SSD 480 Gb
- VideoCard : ASUS Radeon R9 290X Matrix
- Power Unit : Corsair AX1200i, 1200W
- Operating System : Windows 8.1 Professional (64-bit)
The drive’s true capacity is 31, 466, 323, 968 bytes, which when recalculated gives about 29.3 gigabytes. The drive uses Toshiba’s TLC memory and a Phison PS2307 controller, which is used in many USB flash drives manufactured by Kingston.
You can plug the stick in either side, because the USB Type C connector is symmetrical. The USB drive sits very tightly in the connector, it requires a small amount of force to pull it out.
A set of test applications :
- ATTO disk benchmark 2.4.7
- Crystal Disk Mark 4.0.3
ATTO disk benchmark 2.4.7
Synthetic test for estimating correctness of manufacturer’s declared speeds. Actually most of the data on the boxes of flash drives and SSDs from different manufacturers were obtained with ATTO Disk Benchmark.
Crystal Disk Mark 4.0.3
This test evaluates the drive in four modes: linear read/write, read/write blocks of 4K, linear read/write at 32 command queue depth, read/write blocks of 4K at 32 command queue depth.
To estimate the most real-world performance, I burned a BDRemux of The Hobbit. Battle Of Five Armies (file size 28, 851, 025 kilobytes) and recorded the time it took for the movie to copy to the drive.
The first swallow was quite fast and beautiful. The flash drive was not an overpriced solution for the segment of select MacBook owners, in a very compact body it was possible to combine two large connectors with support for high enough reading speed. The metal enclosure, like previous models with two interfaces, increases the reliability and security of the drive.
The only unpleasant thing is the write speed, it’s not high, but again you need to consider the size of the device, a faster controller would just overheat in such a case size.
