Review: Toms Hardware Thanks to OpusP.Gladiator for the Submit. _______________ 2005 was the year of the RAM drive. Gigabyte and a smaller company called HyperOS released their storage products, which were both meant to replace the conventional hard drive with blazing fast SDRAM. Both provided an exciting look to the future of performance storage products, as they blow away any other hard drive. Gigabyte's i-RAM was the faster solution, thanks to its SATA/150 interface, while the HyperDrive III was limited to UltraATA/100, but supported more memory. HyperOS wants to adjust the ranking with its fourth generation HyperDrive, which offers both SATA/150 and UltraATA/133 interfaces. HyperOS even calls its HyperDrive 4 the fastest internal hard disk in the world.
