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

Since the Momentus XT is a hybrid drive, we chose a few different options for comparison. We chose the Kingston HyperX because it represents one of the fastest pure SSD drives you can buy. Seagate compares the Momentus XT line to that of OCZ’s RevoDrive Hybrid drive although it’s PCI-E based and has a lot more SSD capacity in addition to the spinning platter.


Seagate Momentus XT 500GB
HDD Controller No SATA II
Seagate Momentus 750GB
HDD Controller No SATA II
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 but not TRIM. The drive is connected via a SATA III interface with a platter speed of 7200RPM. This is a great free tool to see information about the drive – especially the firmware version. Obviously, the SSD capacity is not listed out here.


On to the benchmarks!
