Seagate Cheetah 18XL ST318404LW

The Cheetah lives up to its name by being the fastest drive in this roundup. Featuring SAMS, SeagateÆs Advanced Multi Drive System, which optimises performance in server and RAID applications, and G-Force Protection (drive design enhancements that protect the devicesÆ data from external shock), the 18.4 GB Cheetah 18XL has a cache of 4 MB and a disk rotational speed of 10,033 RPM. Top-notch performance was reflected in the benchmark scores, which are as follows: 22278 drive index in SiSoft Sandra, 18.88 MBps High End Disk Winmark, 33.76 MBps beginning transfer rate, 23.65 MBps end transfer rate, 184.75 I/Os per second, and a response time of 5.41 ms. This is a great storage solution for the server level, but at a cost of Rs 2.39 per MB, it might prove to be a little expensive.
