Effective Speed: Very poor (13th percentile)

The Emtec C650 is not particularly well made, the retractable mechanism feels cheap and the drive does not perform particularly well either. At this time there are far better deals to be had. [Aug '12 USBFlashPro]

Packaging & Contents

The Emtec C650 ships on a small piece of card with a plastic bubble housing the drive. On the front of the package we found the capacity of the drive, a claimed read speed of 50 MB/s and details of the five year warranty. No write speed ratings were indicated on the box.

Dimensions & Weight

The Emtec measures 5.4cm long, 2.1cm wide and 1.0cm high. Due to its shape the Emtec looks a lot smaller in the hand than its dimensions would indicate, that's because the dimensions quoted for the drive are at its widest point. In terms of weight at 10 grams the Emtec is amongst the lighter drives.

Build Quality

The Emtec has below average build quality. The retractable mechanism feels a little cheap and the drive is a little hollow. At the back of the drive there is a hole where a keychain can be attached. The back of the drive also has is a permanently on red LED which flashes when the drive is in use.

Test System

The test rig was a high end Core-i7 workstation kitted out with a 256GB Solid State drive and 16GB of RAM. The system was designed to be overclocked to 5GHZ but for the benchmarks, only the stock frequencies of 1.6GHz idle, 3.4GHz active and 3.8GHz turbo boost were used.

CrystalDiskMark Speed Test[FAQ]

CrystalDiskMark is a free disk benchmarking utility that is very simple to use. It takes eight measurements: the read and write speeds in megabytes per second (MBps) for sequential, 512KB, random 4KB and 4KB parallel disk operations. There are more screenshots from this benchmark posted on the web than any other, probably due to its clean and simple display. There is further information, including instructions on how to benchmark your own drives, on the CrystalDiskMark wiki page.

CrystalDiskMark Score

The Emtec C650 scored 44/24 MB/s in the sequential read/write tests. This read speed is well below average and just a little over the maximum achievable on a USB 2.0 device which is disappointing. The write speed is about average for a USB 3.0 drive. The strongest relative area of performance for this drive is its 4K read speed which clocked in at 8.2 MB/s and is amongst the higher readings we have seen. Overall the Emtec has below average performance.

ATTO Disk Benchmark[FAQ]

The Atto Disk Benchmark has probably been around for longer than any other disk benchmarking software, and you can tell from its dated interface! The utility was designed to measure regular disk drive performance but it's more than up to the task of measuring both USB flash drive and SSD speeds as well. The utility measures disk performance rates for various sizes of file and displays the results in a bar chart showing read and write speeds at each file size. The results are displayed in megabytes per second (MBps). There is further information, including instructions on how to benchmark your own drive, on the Atto wiki page.

ATTO Score

The ATTO results for the Emtec C650 are broadly in line with the CrystalDiskMark scores and at 45/25 MB/s come in a little under Emtecs claimed read/write speeds of 50/30 MB/s.

AS SSD Real World Copy Speed[FAQ]

The AS SSD benchmarking program was recently developed specifically for benchmarking SSD's. The utility is able to take several measurements that are well suited to solid state drives. One of the tests, ISO copy, is also relevant to slower storage devices including flash drives. The ISO copy test places two large 500MB files in a folder on the drive and then times how long it takes to copy the folder to another location on the same drive. The result is reported in both MBps and time taken. It's a real-world test that gauges a drives ability to read and write at the same time. Drives that have a good balance between their read and write speed fare relatively well on this test. There is further information, including instructions on how to use it to benchmark your own drive, on the AS SSD wiki page.

Real World Copy Speed Score

This test shows that the Emtec C650 would take 75 seconds to create a copy of a large 1GB video file. Generally flash drives complete this test at roughly half their sequential write rates. The Emtec performed as expected in this test.

Conclusion

The Emtec C650 is not particularly well made, the retractable mechanism feels cheap and the drive does not perform particularly well either. At this time there are far better deals to be had.
