Corsair Padlock 2

Apr 4th, 2010 | By Simon


In order to test the Corsair Padlock 2, I will be subjecting it to a few benchmarks: IOMeter, ATTO Diskbenchmark and Crystal Disk Mark. I won’t cover any installation details because it is plug and play – no drivers or software required.


  • CPU: Intel C2D Q6600 (G0 SLACR L731B434) @ 2.71GHz
  • MB: Asus P5E3-Dlx Wifi-AP Edition
  • GPU: Sapphire HD 4850 X2 Catalyst
  • RAM: Aeneon 2×2GB XTune DDR3-1600 (AXH860UD20-16H) @ 1800MHz 10-10-10-30 1T
  • PSU: Cooler Master Real Power Pro 850W
  • CPU Cooling: Thermalright HR-01 w/ 120mm Antec Tri-Cool Fan
  • PWM/NB/SB Cooling: Stock/Stock/Stock
  • HDD: Seagate Barracuda 7200.9 80GB 7200RPM 8MB Cache (ST3808110AS)
  • OS: Windows XP Pro SP3
    USB Flash Drives

  • Corsair Padlock 2
  • Corsair Flash Survivor GT
  • OCZ ATV Turbo

IOMeter is an I/O subsystem measurement and characteristic tool for single and clustered systems initially designed by Intel.

IOMeter is both a workload generator (that is, it performs I/O operations in order to stress the system) and a measurement tool (that is, it examines and records the performance of its I/O operations and their impact on the system). It can be configured to emulate the disk or network I/O load of any program or benchmark, or can be used to generate entirely synthetic I/O loads. It can generate and measure loads on single or multiple (networked) systems.

Iometer shows the Padlock 2 performing at about half the speed of the competition. However, one must keep in mind that this drive is intended for secure files. Most of these will be small documents where you really won’t notice the difference between a transfer time of 30 seconds and 32 seconds.

ATTO Diskbenchmark
ATTO Diskbenchmark is an old but popular benchmarking tool. It captures the read and write performance at different transfer sizes for a fixed file size.

The ATTO Diskbench shows the write speed to max out at 11MB/s and the read speed to max out at 18MB/s.

Crystal Disk Mark
Crystal Disk Mark tests the read and write speed for a user selected file size at three different transfer rates: sequential, 512K and 4K. I selected a 1000MB test file.

  1. Nice review. I bought the 16GB version and have to say I am very happy. I wish the drive was a little faster and smaller but it’s not terribly slow and it’s the best solution for me.

    I did quite a bit of research and tested other solutions. I had my heart set on the IronKey but I found out you cannot use that drive on just any computer. A lot of public and client computers do not allow portable executables to be run from external drives. The IronKey requires you to run its built-in login executable to gain access to the drive.

    Since the Padlock2 is now encased in epoxy, I think its security is more than sufficient. I even added software encryption so I also have an encrypted container for items I really want to secure.
