Comparison Drives & Test System

Legit Reviews Test System

All tests were performed on a fresh and up-to-date install of Windows 7 Pro x64 with no other applications running while using AHCI mode set through the BIOS. Synthetic Benchmarks were run with the OS loaded on a 40GB Corsair Force SSD. In between every test, the test drive was secure erased (in the case of SSDs) using an instance of Parted Magic or the proprietary software for that particular drive. As such, all results should be indicative of optimal performance. All components were set to their default speeds and are listed below. We’d like to thank ASUS for their generosity and support in providing the motherboard for our test bench.

Comparison Drives & Other Models We Have Tested

Even though it’s a bit unfair to the hard drives, we thought it would be helpful to have a few SSD flavored drives in the mix for the sake of comparison. We all know that SSDs stomp hard drives in just about every category save capacity but it’s always nice to see the performance in action. We chose the Kingston HyperX because it represents one of the fastest pure SSD drives you can buy and the RevoDrive Hybrid because of its unique mix of SSD and spinning platter.

DRIVE MODEL CONTROLLER(S) TRIM? Interface
Kingston HyperX 240GB
SandForce SF-2200 (SF-2281) Yes SATA III
OCZ RevoDrive Hybrid 1TB
SandForce SF-2200 (SF-2281)x4 Yes* PCI-E
Western Digital VelociRaptor 300GB HDD Controller N/A SATA II
* TRIM is not supported due to the RAID controller.

In the readout on CrystalDiskInfo 4.0.2, both NCQ and S.M.A.R.T. are enabled. The drive is connected via a SATA II interface with a platter speed of 7200RPM and a 16MB buffer cache. This is a great free tool to see information about the drive – especially the firmware version.
