Manufacturer LSI has presented a controller card which significantly improves data transfer speeds through the SAS/SATA interface.
LSI, a specialist in storage and network solutions, recently unveiled their LSISAS3008 expansion card.

To back up these claims, the manufacturer has conducted a small demonstration with 32 Seagate Savvio 15.3K hard drives, with the performance being measures by the IOMeter benchmarking tool. Data peaks of 3 106.84 MB/s and 1.013 million IOPS were recorded, with this being 65 and 58% better than with a standard 6 Gbit/s SATA controller. These are rather impressive results!
Pour appuyer ses dires, le fabricant a fait une petite démonstration à l’aide de 32 disques durs Seagate Savvio 15.3K, avec des mesures réalisées par l’outil de bencharmarking IOMeter. Sont alors ressortis des pics à 3 106,84 Mo/s et 1,013 million IOPS, soit 65 et 58 % de mieux qu’avec un contrôleur SATA 6 Gbit/s classique. Tout simplement impressionnant !
