Product Overview of the HC490 Dell SCSI Hard Drive
The HC490 300GB 10000 RPM SCSI hard disk drive is a high-performance storage solution designed for use in servers. Manufactured by Dell, this hard drive is built to provide reliable and fast data storage and retrieval for businesses and organizations with demanding storage requirements.
The HC490 hard disk drive comes in a 3.5-inch form factor, which is the standard size for most server hard drives. This size allows it to fit seamlessly into most server chassis and provide a high level of storage density in a compact space.
With a storage capacity of 300GB, the HC490 is capable of storing a large amount of data, making it ideal for use in servers that need to store large amounts of information. This capacity is sufficient for most businesses and organizations, making it an excellent choice for general-purpose storage.
Speed & Interface
One of the most important factors in server storage is speed, and the HC490 delivers in this area. With a spindle speed of 10000 RPM, it is capable of reading and writing data at a much faster rate than traditional hard drives. This speed ensures that data is retrieved quickly and efficiently, reducing the time required for server processes.
The HC490 is equipped with an Ultra 320 80 Pin SCSI interface, which allows it to communicate with the server's SCSI controller. This interface is compatible with most SCSI controllers, making it easy to integrate into existing server systems. The 80-pin SCSI connector also provides a reliable and high-speed data transfer rate, ensuring that data is transferred quickly and without errors.
Hot Swap Capability
One of the key features of the HC490 is its hot-swappable design. This means that the hard drive can be removed and replaced while the server is running, without having to power down the system. This feature is important for businesses and organizations that require uninterrupted server uptime and can't afford to have their systems go offline for maintenance or upgrades.
Dell is known for producing high-quality server components, and the HC490 is no exception. It is built to withstand the demands of continuous server operation and is designed to provide reliable and consistent performance over time. This reliability is important for businesses and organizations that require a high level of uptime for their server systems.
In summary, the HC490 300GB 10000 RPM SCSI hard disk drive is an excellent choice for businesses and organizations that require high-performance and reliable storage solutions for their server systems. With its fast spindle speed, large storage capacity, hot-swap capability, and reliable design, it is capable of meeting the demands of even the most demanding server environments. Manufactured by Dell, it is backed by the company's reputation for quality and reliability, making it a safe and reliable choice for any server system.

About Refurbished Products
The ultra320 SCSI hard drive generation is the immediate upgrade of its predecessor, the ultra160 SCSI. The newer generation ultra320 SCSI HDD comes about as an implementation of the SCSI-3 Parallel Interface-4 (SPI-4) standards.
Over its lifetime, the SCSI standard is widely used in servers and high-end workstations. It is possible to install SCSI HDDs in a desktop PC that has one or more IDE disk drives. The IDE drive acts as the boot drive, while the SCSI hard drive provides additional storage capacity. SCSI is not commonly used in desktop PCs, although it allows the addition of a scanner and several other drives such as DVD-RAM, CD-Rs, and Zip drives to a single SCSI cable chain. USB and FireWire have gradually replaced the SCSI as alternate interfaces in the latest desktop PCs.
In-network servers, SCSI allows for the setting up of several hard drives in the RAID configuration to reduce the risk of loss of data. The configuration supports hot-swapping - the changing of hard drives while the system is still operating.
Ultra320 SCSI HDD just as the name suggests delivers 320 Mbps top speed and provides a faster bus at 80 MHz and a wider data path at 16 bit. Connections with the Ultra320 SCSI HDDs just like with SCSI devices can be daisy-chained since they have two ports - the incoming and the outgoing cables. Besides, SCSI has a strong commitment to backward compatibility with previous generations, which explains its widespread use as an I/O interface and the elimination of the need for substantial investments in equipment and infrastructure. Migration to the ultra320 SCSI HDD is smooth whether it is from the Ultra160 SCSI or other generations of the SCSI standard because of backward compatibility.
The ultra320 SCSI hard drive takes on technologies such as domain validation, cyclic redundancy check, and dual-edge clocking first introduced by ultra160 SCSI. Additionally, the ultra320 SCSI hard drive introduces protocol changes and other technologies that enhance performance and support reliable data transfer speeds at 320 Mbps. We have the following ultra320 SCSI HDD options: 146GB-10K RPM, 146GB-15K RPM, 300GB-10K RPM, 300GB-15K RPM, 36GB-10K RPM, 36GB-15K RPM, 73GB-10K RPM, 73GB-15K RPM, and 18GB-15K RPM to meet your performance and storage requirements.
The standard features of the ultra320 SCSI hard drive include:
- Two-fold increase in transfer speed: The ultra320 SCSI hard drive increases the transfer rate by 100% from the previous generation at the rate of 320 Mbps. The technology allows greater transfer rates, effectively leading to greater performance in environments of extended data transfer and support for many devices on a single bus.
- Support for SCSI packet protocol: By enabling packet protocols, the ultra320 SCSI HDD helps to reduce command overhead by using dual transition (DT) data phases to transfer data, commands, and statuses rather than asynchronous phases that are generally slow. Packet protocol allows for the transfer of multiple commands in one connection as well as increased performance through minimal command overhead and maximum bus utilization.
- Quick Arbitration and Selection (QAS): the technology helps reduce control release overhead between devices at the SCSI bus. QAS is all about reducing command overhead and maximizing utilization of the bus.
- Read/Write Data Streaming facilitates the reduction of overhead associated with data transfer through the sending of a LUN Q-TAG (LQ) data stream packet, which is subsequently followed by multiple data packets. Greater write data streaming is achieved since the bus turnaround delay is eliminated between LQ and data packets.
- The flow control feature facilitates the initiator to enhance the pre-fetching of data for writes and enhance the flushing of FIFOs for reads.
