512547-B21

The code 512547-B21 refers to a specific model of hard disk drive (HDD) manufactured by Hewlett-Packard (HP). Here's a breakdown of the potential functionalities and specifications:

• Manufacturer: Hewlett-Packard (HP)
• Model Number: 512547-B21

Potential Specifications (based on publicly available information):

• Capacity: 146GB - This is a relatively small storage capacity by modern standards, but it was common for HDDs in the mid-2000s.
• Interface: SAS (Serial Attached SCSI) - This is a high-performance interface commonly used in enterprise storage systems and servers. It offers faster data transfer rates compared to traditional SATA (Serial ATA) interfaces used in consumer-grade computers.
• Speed: Up to 750MB/s (potential) - The exact speed might depend on the specific model and SAS interface generation.
• Form Factor: 2.5-inch - This is a standard size for laptop hard drives and can also be used in some smaller servers.
• RPM (Rotations Per Minute): 15,000 RPM (likely) - This is a high RPM rating, indicating the drive can spin faster to access data quicker. However, it also translates to higher noise levels and power consumption compared to slower RPM drives.
