Performance of the drive turned out to be pretty much as specified by the manufacture. We used the following test system to measure the drive's performance.

 

Processor Athlon XP 1.8GHz
Motherboard SOYO KT333 Dragon Ultra
Memory 256MB Crucial PC 2700 DDR SDRAM
Hard Drive IBM 75GXP 60GB - ATA 100
Operating System Windows XP Professional
Motherboard USB Drivers SOYO USB 2.0 Driverv2.0.2

The TapeWare XE provides a graphical view of the operating speed of the drive. Once you turn on the ADR2 60USB drive, it takes around 10-15 seconds to initialize. Thereafter you're ready for action. In some instances if you have specified to format the cartridge it'll take a bit longer before the actual data backing up process starts. The following table shows the tests we carried out and the time taken.

File size
Time Taken
Speed (MB/sec)
3GB of various utility programs downloaded from the web
24 min
2.1MB/sec
20GB of Program files
2hrs 42 min
2.31MB/sec

Below is a screen capture of another test where we were backing up some program files. As you can see, in both instances the drive performs close to 2MB/sec or over.

Performance of the drive is without doubt very impressive indeed. Most tape drives out there hardly go beyond the 1MB/sec mark and if you want to go higher, the cost is heartbreaking. I do not know how Onstream does it, but the price they offer these tape drives are simply amazing. Most other tape drives with similar functionality are priced well over US$1000, so these drives are unquestionably a great bargain.

With data compression we were able to get the speed up to around 4.1MB/sec but in all of the tests we did, we weren't able to reach 5MB/sec. Nevertheless it's still extremely impressive.
