The Western Digital WD740HLFS 74GB is a 3.5" 74GB Hard Disk Drive.
It uses the SATA 3Gb/s interface and has a speed of 10000 RPM.
| Drive Type | Hard Disk Drive | This defines whether the drive is a large-capacity slower hard disk drive, a smaller-capacity but much faster solid-state drive, or a hybrid | |
|---|---|---|---|
| Physical Size | 3.5" | The size of the drive dictates which drive bays it will fit into - generally a small drive will fit into any bigger drive bay with an adapter | |
| Capacity | 74GB | The drive storage capacity is the limit to the size of files that can be stored | |
| RPM | 10000 RPM | The higher the RPM, the faster the hard drive, and the faster stored data can be accessed | |
| Drive Interface | SATA 3Gb/s | The interface is the type of motherboard connection and defines the bandwidth limit of the drive |
The Western Digital WD740HLFS 74GB is a hard disk drive, which means it stores data using quickly rotating disks, or platters, that can be read and written on via the moving actuator arm. Hard disk drives generally have a large storage capacity, and so are perfect for large amounts of data. The potential performance is well below that of solid-state drives, but they can definitely still hold their own. The Western Digital WD740HLFS 74GB is a decent primary hard disk drive choice, but its performance is somewhat lacking.
At a speed of 10000 RPM, the hard disk drive spins at among the fastest speed available on the hard disk drive market, which is a good indicator of its high performance and low latency. Its speed may be louder than desired, and if the platters are poorly designed the high speed could have long-term reliability repercussions, however.
With a capacity of 74GB, the Western Digital WD740HLFS 74GB has a tiny amount of storage space for an hard disk drive. Using the SATA 2.0 3Gb/s interface this hard disk drive will not be limited by its connection with the motherboard, and there is currently no real reason to choose SATA 3.0 over SATA 2.0 for a mechanical hard disk drive (SSDs are another matter).
A form factor size of 3.5" is standard for desktop drives, and this will fit into any standard case drive bay, or into a 5.25" drive bay with an adapter.
