We used following test setup during our tests:
Lenovo Thinkpad T61
Core 2 Duo T7700
2x2GB DDR2 800MHz
Seagate 7200rpm 2.5″ HDD
Nvidia Quadro NVS 140M
We used CrystalDiskMark to test the performance of our drives. We used the 500MB template with three loops to give us somewhat accurate results.
Let’s first take a look at our reference drive. The 7200RPM 2.5″ internal drive made by Seagate should give us a rough reference what a typical 2.5″ SATA2 drive is capable of. Our drive was semi-full and had an operating system in it. That will affect the test results a bit but the drive should nevertheless give us a good estimate. Seagate 7200rpm drive manages to push about 73MB/s results in sequental read/write while the results with 512k chunk sizes are about the half of it. With 4k and 4kQD32 sizes the results are less than 1MB/s in both read and write.
We can only be suprised by the performance of the Verbatim Store ‘n’ Go Traveller: USB 3.0 drive. Despite being only 5400rpm drive, it manages to push about 20MB/s higher results than the internal drive did in the sequental test. When we look at the 512k chunk sizes, the read performance is about the same as with the internal drive, but the write performance is only half of it. Also the internal 7200rpm manages to get better results with 4k and 4kQD32 tests thanks to its faster seek speed due the faster rpm.
As comparison we also tested the drive in an USB2.0 slot. Drive manages to easily saturate the full capacity of the USB2.0 bus. While, in theory, USB2.0 can push up to 60MB/s (480Mbps) speeds – in reality we often see it capping at around 30-35MB/s (240Mbps-320Mbps). In sequential test Verbatim Store ‘n’ Go Traveller: USB3.0 gives us 30MB/s speed in read test and 15MB/s speed in write test.
Clearly the performance is not the issue with USB3.0 hard disks. Verbatim Store ‘n’ Go Traveller: USB3.0 performs better in most sections than our 7200rpm drive inside the test laptop. It gets only beaten in small random data as the seek speeds on 5400rpm drive are slower than what our test laptops internal HDD had. Verbatim Store ‘n’ Go Traveller USB 3.0 750GB is priced around 100€ and should be available as we speak. It seems that the prices of USB3.0 hard disks are similar to USB2.0 drives and I don’t see any reason why not to go with one if you get to choose. The only thing I didn’t like with the drive was the enclosure. Plastic is not the strongest material to make your enclosures from, they get cracked quite easily. Other than that, Verbatim has made marvellous job with their drive. Check Amazon and Newegg for good prices on this unit.
