Now take a look at the results of DataBase pattern from a bit different viewpoint:
Seagate doesn’t have any problems with scalability according to the workload, all the drives perform identically close.
As I have already said, the new HDD models are not very skillful in handling the mixed modes, unlike their predecessor. SerialATA Barracuda is over 20% faster than its Parallel ATA counterparts.
With 100% writes the picture turned completely different: Barracuda Serial ATA V is steadily ahead of its younger fellows.
Well, the first benchmarks results appeared pretty unexpected. Although the electronics of Barracuda 7200.7 is very similar to that of Barracuda ATA V, the latter outperforms the newcomer almost in all parameters. Having boosted up the linear speed (it is the first case lately when the read/write speed grew up as much as the data density) and improved the average access time, Seagate had to sacrifice other HDD features. It’s a great pity, by the way…
