The A-DATA S701 and SDHC Eee PC edition are essentially identical to the normal variants of these flash memory devices. A-DATA has only colored and branded the parts to go well with the Eee PC. Considering this, the only reason you would go for this edition is the fact, that you would want to use it with the ASUS subnotebook. The USB drive does attain very good read speeds, while the SDHC card manages to be quite fast for such a format as well.
The write speeds on the other hand are certainly nothing you would want to see on any device used as a hard drive, but the fault seems to lie with the ASUS Eee PC, which does not manage to squeeze out the most out of the Flash drive and not even half the write speed on the SDHC card. The latter performance drop stems from the internal SDHC card reader. But considering that both the S701 and the SDHC card are meant to be used as a secondary drive, not a primary booting one, they should work fine in such a scenario.

Overall, even if the performance numbers seem low, when compared to the internal SSD drive of the Eee PC, each of the two units we reviewed here perform well in respect to their interface and format. It is hard to say which one of the two would be the better choice. The SDHC card has a slightly better write performance and can be inserted permanently into the Eee PC, while the S701 offers great read performance but is a bit loose when connected and needs to be removed every time you wish to move around with the subnotebook.

Marketing their durable, portable and fast flash memory devices for the Eee PC is a great idea from A-DATA and luckily the company is not asking for a price premium over the normal variant of both parts. It would be good to see further difference between the two series, like NTFS formatting on the Eee PC parts for example.
