Dell UD558 is a hard disk drive designed for enterprise-level server applications. It is a 146GB drive with a spindle speed of 15,000 revolutions per minute (RPM), making it a high-performance hard disk drive. The drive uses an Ultra-320 SCSI interface and has a 3.5-inch form factor. The drive comes with a tray and supports hot-swapping, which means you can replace the drive while the server is still running.
Form FactorThe form factor of a hard disk drive refers to its physical size and shape. The Dell UD558 has a 3.5-inch form factor, which is the standard size for enterprise-level hard disk drives. The 3.5-inch form factor is larger than the 2.5-inch form factor used in many laptop hard disk drives. The larger size allows for more platters to be included, which increases the storage capacity of the drive.
InterfaceThe Dell UD558 uses an Ultra-320 SCSI interface. SCSI stands for Small Computer System Interface, which is a set of standards for connecting computer peripherals. The SCSI interface is a popular interface used in enterprise-level servers because it provides fast data transfer rates and supports multiple devices on a single bus.
SpeedThe spindle speed of a hard disk drive refers to the rate at which the platters inside the drive rotate. The Dell UD558 has a spindle speed of 15,000 RPM, which is considered high-performance. A high spindle speed allows for faster read and write times, which is important in enterprise-level applications where speed is critical.
CapacityThe Dell UD558 has a storage capacity of 146GB. This is considered a relatively small capacity compared to modern hard disk drives, but it was a common capacity for enterprise-level hard disk drives when the Dell UD558 was released. The small capacity was due to the limited space available on the platters inside the drive.
Hot Swap
The Dell UD558 supports hot-swapping, which means you can replace the drive while the server is still running. This is a useful feature in enterprise-level applications where downtime is costly. Hot-swapping allows you to replace a faulty drive without shutting down the server, which reduces the amount of downtime and increases the overall reliability of the system.
Low Profile
The Dell UD558 has a low profile, which means it is designed to fit in servers with limited space. A low profile drive is thinner than a standard drive, which allows it to fit in small form factor servers. The low profile design also reduces the weight of the drive, which can be important in large-scale deployments where many drives need to be installed.
Tray
The Dell UD558 comes with a tray, which is used to mount the drive in the server. The tray is designed to fit the 3.5-inch form factor of the drive and provides a secure mount that can withstand the vibrations and shocks that can occur in enterprise-level server environments.
Summary, the Dell UD558 is a high-performance hard disk drive designed for enterprise-level server applications. It has a 146GB capacity and a spindle speed of 15,000 RPM, making it a fast and reliable drive. The drive uses an Ultra-320 SCSI interface and has a 3.5-inch form factor. It comes with a tray and supports hot-swapping, which makes it easy to replace a faulty drive without downtime. The low profile design of the drive allows it to fit in servers with limited space, making it a versatile option for large-scale deployments.
