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.

incredibly SLOW

Peter E., Newegg
30 April 2014
  • Summary: Now I don't have to worry when I give someone a set of files on a thumbdrive if I'll get the drive back. In this case I hope it doesn't come back.
  • Pros: Cheap, they were on sale ($5each) and I should have known better. Every time such a sale happens it's because someone is dumping something already judged useless by the general world.
  • Cons: CrystalDiskMark took so long to set up the test file for diagnostics that I thought it had crashed. I haven't seen a drive this SLOW in years. 15MB/s read, 5 MB/s write. It is quickly recognized by the Windows7 system (seconds), that is why I gave it two eggs instead of one.

The speed is unbearable slow!

  • 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.
