By Stephanie Whalen. At HP we believe business success is all about your data. One of the most important investments you can make is in your drives. A common question we get is "isn't your drive the same as what I can buy through a retail chain?" The answer is a resounding NO.
There are several differences and reasons why HP drives are the best choice for your HP ProLiant, Integrity and StorageWorks platforms. First and foremost is the rigorous HP qualification process known as the Hard Disk Drive Qualification (HDDQ) system. HDDQ covers a multitude of design aspects, such as, drop tests, random vibration, temperature testing, signal integrity, power, performance, rotational vibration and the list goes on and on. If the drive doesn't pass any part of the test, corrective measures are taken to fix anything out of spec before the drive is released to production - OR the drive gets the boot. By the time all required testing is completed, HP drives have endured in excess of 2 million drive test hours. Second, HP and our drive suppliers walk hand-in-hand throughout this process to ensure the best possible drive is delivered to our customers. We continue to do so even after the drive is in full production. It is through the HP Hard Disk Drive (HDD) closed-loop quality system where we and the drive suppliers ensure all quality metric goals are achieved and continues to do so throughout the lifecycle of the product.
Our drives have been tested to ensure compatibility and optimized to work with our servers and storage enclosures. Through the combination of server chassis design, qualification testing, HP drive firmware, and drive technology, HP drives provide better performance, less downtime and increased data integrity than third-party drives. Without proper engineering, drive performance can suffer from 25% to 50% due to vibration and retries, however with the right chassis design and drive trays and correct type of drives, HP drives operate at optimal performance level.
The proof is in the pudding. Based on vendor statistics our HP drives for enterprise applications have up to 50% less return rate compared to drives sold in the retail space.
Makes you wonder what you get when you buy off the shelf.
