Fast reads, slow writes

Terran M., Newegg
22 August 2014
  • Summary: One of the lowest prices on 64GB USB drives, at least at the time I got it. Overall good value for low-write, high-read workloads. I would not recommend for a write-heavy workload.
  • Pros: 15 MB/sec reads. Physically robust. It's the slide kind with no cover to lose. Read performance from iostat: Device: rrqm/s wrqm/s r/s w/s rkB/s wkB/s avgrq-sz avgqu-sz await r_await w_await svctm %util sdh 3591.10 0.00 226.40 0.00 15258.40 0.00 134.79 3.62 15.98 15.98 0.00 4.42 100.00 sdh 3588.60 0.00 229.00 0.00 15270.40 0.00 133.37 3.67 16.03 16.03 0.00 4.37 100.00 sdh 3605.30 0.00 231.50 0.00 15347.20 0.00 132.59 3.68 15.91 15.91 0.00 4.32 100.00
  • Cons: Actual capacity only 57 GB. Very slow writes. Less than 1 MB/sec sustained write throughput. Here's some sar results from copying files to it with rsync; ext4 fs with journal disabled: 12:00:01 AM DEV tps rd_sec/s wr_sec/s avgrq-sz avgqu-sz await svctm %util 11:20:01 AM sdh 6.56 1.07 1477.03 225.18 139.03 20815.65 150.52 98.80 11:30:01 AM sdh 5.37 0.00 1236.49 230.08 143.46 26831.27 186.08 100.00 At this rate, writing 60 GB would take about a day.

  • Summary: Works well. I'd only get USB 3.0 from now on due to greater speed (only if you have 3.0 port).

Looks great, works great.

  • Summary: When i opened this i tested it right away by dragging a 5GB file into it, and the transferring time was relatively quick. The drive looks very nice and has a nice design, and the price for it was definitely worth it. Relatively quick flash drive with a great price.

  • Summary: The speed is too slow for a usb2.0 thumb drive. The average speed is around 4MB/s. Way below the standard usb2.0 speed. Very disappointed.

5 MB/sec write, 15 MB/sec read

Terran M., Newegg

  • Summary: Reasonable value overall. USB device IDs as Kingston - 13fe:4100.
  • Pros: Good price. 61.9 * 10^9 bytes.
  • Cons: Not particularly fast. Getting 5 MB/sec writes, which will take about 3 hours to fill the drive. Reads are 15 MB/sec.

  • Summary: Put a bunch of music on it and hooked it up in my car. Stereo reads it quickly and it hasn't let me down yet. Great little flash drive. Recommended.
