6.3Reliability

6.3.1Data reliability

Probability of not recovering data is 1 in 1013 bits read ECC implementation

On-the-fly correction performed as a part of read channel function recovers up to 16 symbols of error in 1 sector (1 symbol is 10 bits).

6.3.2Failure prediction (S.M.A.R.T.)

The drive supports Self-monitoring, analysis and reporting technology (S.M.A.R.T.) function. The details are described in section 11.8, "S.M.A.R.T. Function" on page 84 and in Section 13.32, "S.M.A.R.T. Function Set (B0h)" on page 163.

6.3.3Cable noise interference

To avoid any degradation of performance throughput or error when the interface cable is routed on top or comes in contact with the HDA assembly, the drive must be grounded electrically to the system frame by four screws. The common mode noise or voltage level difference between the system frame and power cable ground or AT interface cable ground should be in the allowable level specified in the power requirement section.

6.3.4Service life and usage condition

The drive is designed to be used under the following conditions:

The drive should be operated within specifications of shock, vibration, temperature, humidity, altitude, and magnetic field.

The drive should be protected from ESD.

The breathing hole in the top cover of the drive should not be covered. Force should not be applied to the cover of the drive.

The specified power requirements of the drive should be satisfied.

The drive frame should be grounded electrically to the system through four screws. The drive should be mounted with the recommended screw depth and torque.

The interface physical and electrical requirements of the drive should satisfy ATA-6.

The power-off sequence of the drive should comply with the 6.4.6.2,"Required power-off sequence.”

Service life of the drive is approximately 5 years or 20,000 power on hours, whichever comes first, under the following assumptions:

Less than 333 power on hours per month.

Seeking/Writing/Reading operation is less than 20% of power on hours.

This does not represent any warranty or warranty period. Applicable warranty and warranty period are covered by the purchase agreement.

HDS723020BLA642 specifications

The Hitachi HDS723020BLA642 is a high-performance hard disk drive that exemplifies the balance between reliability and advanced technology, making it an excellent choice for a range of applications, from desktop computers to enterprise storage solutions. This 2TB SATA hard drive is designed to meet the growing data storage needs of users who demand both speed and efficiency.

One of the key features of the HDS723020BLA642 is its impressive rotational speed of 7200 RPM. This speed facilitates faster data access and improved overall performance, significantly enhancing the user experience during data-intensive operations such as gaming, video editing, and large file transfers. Coupled with a SATA III interface, this drive facilitates data transfer rates of up to 6 Gb/s, providing an efficient conduit for moving data quickly between the hard drive and the motherboard.

The drive comes equipped with a large 64 MB cache, which plays a crucial role in buffering read and write operations. This substantial amount of cache memory allows the drive to temporarily store frequently accessed data, leading to reduced latency and enabling smoother multitasking capabilities. Users will benefit from faster load times and reduced wait periods when working with large files.

Reliability is another defining characteristic of the HDS723020BLA642. Hitachi, now a part of Western Digital, has a longstanding reputation for producing durable hard drives. This model incorporates advanced technologies, such as the Fluid Dynamic Bearing (FDB) for quieter operation and better longevity. The drive also features an enhanced error recovery system that minimizes the risk of data loss, making it a suitable option for both personal and professional use.

In terms of power efficiency, the HDS723020BLA642 is designed to consume less power during operation compared to older hard drive models. This efficiency not only helps in reducing operational costs but also contributes to a longer lifespan for the drive itself.

Overall, the Hitachi HDS723020BLA642 hard drive combines speed, reliability, and efficiency into a compact package, making it an ideal choice for users needing a substantial amount of storage without compromising on performance. Whether for upgrading an existing system or building a new one, this drive offers a blend of technology and durability that caters to modern storage demands.
