StorageReview.com's Drive Performance Resource Center
Select an option from the drop-down menu above. The resulting query will deliver a sort of all drives evaluated in StorageReview's fourth-generation testbed and allows further detailed comparison between selected drives. Sorts of the following tests are available:
StorageReview.com Office DriveMark 2006 - A capture of Veritest's Business Winstone 2004 suite. Applications include Microsoft's Office XP (Word, Excel, Access, Outlook, and Project), Internet Explorer 6.0, Symantec Antivirus 2002 and Winzip 9.0 executed in a lightly-multitasked manner.
StorageReview.com High-End DriveMark 2006 - A capture of VeriTest's Multimedia Content Creation Winstone 2004 suite. Applications include Adobe Photoshop v7.01, Adobe Premiere v6.5, Macromedia Director MX v9.0, Macromedia Dreamweaver MX v6.1, Microsoft Windows Media Encoder 9.0, Newtek Lightwave 3D 7.5b, and Steinberg Wavelab 4.0f run in a lightly-multitasked manner.
FarCry - A capture of a first-person shooter that remains infamous for its lengthy map loads when switching levels.
The Sims 2 - A capture of a strategy game that spends considerable time accessing the disk when loading houses and lots.
World of Warcraft - A capture of a role-playing game that issues disk accesses when switching continents/dungeons as well as when loading new textures into RAM on the fly.
IOMeter File Server Tests - The IOMeter File Server pattern simulates multi-user activity by issuing a majority of reads and minority of writes spanning requests of varying sizes. The benchmark also facilitates user-configurable load levels by maintaining queue levels (outstanding I/Os) of a specified depth. StorageReview's tests start at a depth of 1 and double continuously until queue length reaches 128 outstanding I/Os.
Average Read Access Time - An average of 25,000 random read accesses of a single sector each conducted through IPEAK SPT's AnalyzeDisk suite. The high sample size permits a much more accurate reading than most typical benchmarks deliver and provides an excellent figure with which one may contrast the claimed access time (claimed seek time + the drive spindle speed's average rotational latency) provided by manufacturers.
Average Write Access Time - An average of 25,000 random write accesses of a single sector each conducted through IPEAK SPT's AnalyzeDisk suite. The high sample size permits a much more accurate reading than most typical benchmarks deliver.
WB99 Disk/Read Transfer Rate - Begin - The sequential transfer rate attained by the outermost zones in the hard disk. The figure typically represents the highest sustained transfer rate a drive delivers.
WB99 Disk/Read Transfer Rate - End - The sequential transfer rate attained by the innermost zones in the hard disk. The figure typically represents the lowest sustained transfer rate a drive delivers.
Idle Noise - The sound pressure emitted from a drive measured at a distance of 3 millimeters. The close-field measurement allows for increased resolution between drive sound pressures and eliminates interactions from outside environmental noise. Note that while the measurement is an A-weighted decibel score that weighs frequencies in proportion to human ear sensitivity, a low score does not necessarily predict whether or not a drive will exhibit a high-pitch whine that some may find intrusive. Conversely, a high score does not necessarily indicate that the drive exhibits an intrusive noise profile.
Idle Power Dissipation - The power consumed by a drive when idle. In the relatively closed environment of a computer case, power dissipation correlates highly with drive temperature. As a drive dissipates more power, it increases a chassis's internal temperature by a greater amount.
Active Power Dissipation - The power consumed by a drive when under a 100% random seek load. In the relatively closed environment of a computer case, power dissipation correlates highly with drive temperature. As a drive dissipates more power, it increases a chassis's internal temperature by a greater amount.
12V Maximum Power Dissipation - The maximum power drawn on the 12 volt rail by a drive on powerup, typically during platter assembly spinup. This figure is relevant when a system features an array of several drives. Though most controllers feature logic that can stagger the spin-up of individual drives, peak power dissipation may nonetheless be of concern in very large arrays or in cases where a staggered start is not feasible.
5V Maximum Power Dissipation - The maximum power drawn on the 5 volt rail by a drive on powerup, typically during actuator initialization.
