What does it mean that the HP 872481-B21 is DS and why is it important?

DS refers to Digitally Signed Firmware. The digitally signed storage drives like HP 872481-B21 give you peace of mind knowing they cannot be modified or corrupted by anyone but the official manufacturer. Digitally signed firmware is an effective way to verify your hard drive’s originality before installing it on a server. It’s sometimes also important for your storage drive’s compatibility with other hardware parts and to acquire warranty support.

What does it mean that the HP 872481-B21 is 2.5" SFF?

SFF stands for the small form factor. The 2.5” storage drives (including HP 872481-B21) pack a relatively compact size of 2.5 inches. To be exact, their dimensions consist of a 2.7 inches width, a 0.37-inch height, and a 3.96 inches length. The small form factor storage drives are commonly used in laptops and game consoles that have a smaller size than computers. But they’re also a fit for desktop computers and servers.

What does it mean that the HP 872481-B21 is a 10K drive?

10K for a hard drive refers to its RPM speed. RPM stands for revolutions per minute. It’s used to measure how fast a hard drive’s platter moves. The higher the RPM speed, the faster a storage drive can access data. The plotter of a 10K RPM speed drive, like the HP 872481-B21, moves 10 thousand times in a minute. Such hard drives are high-performance as regular ones only offer a 5400 or 7200 RPM speed.

What does it mean that the HP 872481-B21 is a SAS 12G drive?

SAS stands for Serial-Attached SCSI. It’s a type of storage drive interface with a versatile array of connectors, making it more effective at reading and writing data. Like HP’s 872481-B21, SAS storage drives are particularly useful for continuous computer operations, like servers and workstations. That said, a 12G SAS drive means it has a bandwidth of 12Gbs (gigabits/second) and allows for faster data transfer rates than most traditional storage drives.

What does it mean that the HP 872481-B21 is a 512e drive?

512e in a hard drive refers to 512 bytes emulated storage of a physical sector. Emulated storage means what size is shown to an operating system or software if needed but is not a reality. The reality of 512e storage drives is that each sector packs 4096-byte storage, following an advanced standard. However, the purpose of the 512 bytes emulated storage is to ensure the drive works well with operating systems that only support traditional hard drives. The format of these 512e drives, like HP's 872481-B21, is called Advanced Format (AF).

What does it mean that the HP 872481-B21 is a SC (Smart Carrier) drive?

SC refers to Smart Carrier. An SC storage drive, like the HP 872481-B21, means that the drive comes with Smart Carrier. The Smart Drive Carrier feature is only available in newer hard drives (Gen8/Gen9) and warns against data loss when detaching a drive. Moreover, the HP hard drives containing this feature are usually termed HP Smart drives. That said, some regular drives are also turned into Smart drives by installing them into a smart drive carrier (smart carrier converter).
