I was able to see read speeds north of 200 megabytes a second. By far the fastest flash drive that I have ever used. I was getting a constant write speed of 125 megabytes a second. It took me no time to copy 10 HD movies over to this drive. It shows virtually no signs of wear and tear after spending almost two months on my keychain. While able to get run over it was on the large side. Previously I was using a corsair survivor. Pros: I've been using this flash drive for nearly two months now. I went back to exFAT and saw consistent 100 MB/s writes again. Interestingly enough, when I reformatted it as NTFS, large file writes would always start at around 100 MB/s and slowly decrease to 60 MB/s. I reformatted it from FAT32 to exFAT and the read/write speeds remained about the same. Overall Review: It does get a little warm during extensive use but this did not cause any problems in my testing. It feels rugged when closed, although the connector remains exposed. The slider is a little stiff to operate and it makes the already wide case a little wider. This flash drive is wider than most and on some computers that does restrict what you can use in the neighboring port. WDC My Passport 1 TB: 4 minutes, 45 seconds. Kingston DataTraveler 3.0 32 GB: 38 minutes, 50 seconds.
Write times were as follows:Ĭorsair Voyager 64 GB Slider X2: 37 minutes, 25 seconds. This Cygwin installation is 4.05 GB spread among 32,905 files in 1,811 subdirectories. I copied a Cygwin installation onto each of these USB drives to get a sense of small file write performance. I've used this on four different computers so far with no problems to report.Ĭons: The improved write performance with large files does not extend to smaller files. When I write to the drive using Linux the copy operation reports that it's complete long before the system is finished writing, so I appreciate being able to tell at a glance that the write is still taking place. My 32 GB flash drives don't have one and I was starting to think activity LEDs on flash drives were a thing of the past. The activity LED is clearly visible without being too bright. It ships formatted as FAT32 and with no unwanted bloatware. WDC My Passport 1 TB: 129.6 MB/s burst, 16.5 ms access time. Kingston DataTraveler 3.0 32 GB: 24.2 MB/s burst, 0.8 ms access time. PQI U822V 32 GB: 31.6 MB/s burst, 0.7 ms access time. WDC My Passport 1 TB: 90 MB/s write, 104 MB/s read.Ĭorsair Voyager 64 GB Slider X2 (using USB 2.0): 36 MB/s write, 41 MB/s read.Īs you can see the write performance is remarkably fast.īenchmarking the write burst rate and random access time gives the following:Ĭorsair Voyager 64 GB Slider X2: 135.8 MB/s burst, 0.8 ms access time. Kingston DataTraveler 3.0 32 GB: 11 MB/s write, 36 MB/s read.
PQI U822V 32 GB: 19 MB/s write, 80 MB/s read. Comparing this with other USB 3.0 drives using a 3.4 GB test file:Ĭorsair Voyager 64 GB Slider X2: 101 MB/s write, 104 MB/s read.
Pros: Read and write performance is excellent when used with large files.
