Description
Product Details of 500GB Hard Drive
The Western Digital WD5000ABYS Re2 is a hard disk drive (HDD) designed specifically for enterprise applications, providing high storage capacity, speed, and reliability. In this article, we will delve into the technical specifications and features of the WD5000ABYS Re2, and explain its benefits and limitations.
Capacity and Speed
The WD5000ABYS Re2 has a storage capacity of 500GB, which is a considerable amount of storage for most enterprise applications. This HDD is also designed to operate at a speed of 7200 revolutions per minute (RPM), which is faster than the standard 5400 RPM that most consumer-grade HDDs operate at. The faster speed results in quicker read and write times, allowing for faster data transfer rates and improved system performance.
Interface and Buffer
The WD5000ABYS Re2 is equipped with a Serial ATA II (SATA-II) interface, which provides faster data transfer rates than the original SATA interface. SATA-II supports data transfer rates of up to 3.0 gigabits per second (Gbps), which is twice as fast as the original SATA interface. This results in quicker access times and improved system performance.
The HDD also has a 16MB buffer, which is a small amount of high-speed memory used to temporarily store data that the HDD is currently reading or writing. The buffer acts as a bridge between the slower HDD and the faster CPU, reducing the overall time required to read and write data.
Enterprise-Class Features
The WD5000ABYS Re2 is designed with enterprise-class features, such as increased reliability and durability. The HDD is rated for 24/7 operation, meaning it is designed to run constantly without failing. This makes it ideal for use in servers or other high-availability systems.
The HDD also features time-limited error recovery (TLER), which is a mechanism that prevents the HDD from spending too much time trying to recover from a failed read or write operation. This helps to prevent the HDD from becoming unresponsive, which could lead to system downtime.
The WD5000ABYS Re2 also has a mean time between failures (MTBF) rating of 1.2 million hours, which is a measure of the expected lifespan of the HDD. This is an extremely high rating, indicating that the HDD is designed to last for many years of continuous operation.
Summary,the Western Digital WD5000ABYS Re2 is an enterprise-class HDD designed for high-performance and high-reliability applications. With its fast speed, large buffer, and SATA-II interface, it provides quick access to data and improved system performance. Its enterprise-class features, such as 24/7 operation and TLER, make it ideal for use in servers and other high-availability systems. While it does have some limitations, such as its storage capacity and cost, the WD5000ABYS Re2 remains a popular choice for enterprise applications where reliability and performance are critical factors.
