Transcend StoreJet 25 Mobile review:

Transcend StoreJet 25 Mobile

Cost per gigabyte
The cost per gigabyte for external storage is falling so quickly that it seems to reduce with each portable drive that comes through our labs. The Transcend StoreJet 25 Mobile is indicative of this trend--the current retail price of our 320GB model is $95, which comes out to $0.30 per gigabyte--by far the cheapest external drive we've tested. In a comparison lineup with four other external drives, the next cheapest, the Seagate FreeAgent Go, is a full $0.17 per gigabyte more than the Transcend. We expect to continue to see prices falling on portable storage devices like these, but right now, you won't find a better offer than this one.

Luckily, the StoreJet 25 Mobile didn't falter in our performance tests at all, delivering a solid 28.49 megabytes per second to read and 23.43 megabytes per second to write across our 10GB data folder. The gap in favor of Transcend between for the speed test benchmarks isn't quite as wide as the cost per gigabyte, but that extra 2MB per second faster than the Clickfree Portable Backup Drive is enough to secure our full recommendation for the Transcend StoreJet 25 Mobile for traveling professionals who need constant and protected access to their sensitive data.

Service and support
Transcend backs all of its external hard drives with a two-year warranty that covers parts and labor, so long as the damage is not a result of "accident, abuse, misuse, natural or personal disaster, or any unauthorized disassembly, repair, or modification." A two-year warranty is acceptable for an external hard drive, but we always prefer three years to ensure the physical integrity of a portable device made to withstand the abuse of daily transport.
