Test Results
Our storage benchmark involves moving a lot of big files, but also over 10,000 files smaller than 50 kB. This mix should give us a good idea of the drives’ real-world performance.
No big surprises here - performance is pretty close to the advertised native specifications.
The Tandberg 420LTO advertised native transfer rates of 24 MB/s, and it managed to hit 20.8 MB/s in our tests. While that’s very close to the claimed figures, we wonder why it’s so far from the LTO-2 standard, which should be 40 MB/s. Once again, we can only assume that the reduced performance is part of the trade-off that Tandberg made to get the drive small and power-miserly.
The external 220LTO is based on the older LTO-1 standard, but managed 14.6 MB/s, which is very close to its advertised 16 MB/s specification, and acceptably close to the LTO-1 standard’s 20 MB/s specification. Of course, as an LTO-1 drive it also only has half the capacity of the 420LTO.
