HPE 300GB SAS 15K 2.5" Drive
This new HPE 300GB SAS hard drive spins at 15000 RPM in a 2.5-inch form factor. It uses a single-port SAS 3Gb/s interface and ships with a hot-plug tray attached. The drive is built for enterprise server environments that demand high transaction throughput. Part number 431944-B21 identifies this specific model.
Suits Single-Port SAS Bays
Buyers who need a 300GB 15K RPM drive for a single-port SAS 3Gb/s backplane will find this unit matches the required interface and form factor. The hot-plug tray allows replacement without powering down the server. Systems that require dual-port SAS connectivity or a native 3.5-inch large form factor chassis should look at a different drive. The 2.5-inch size fits small form factor bays only.
Single-Port SAS 3Gb/s Interface
The single-port SAS 3Gb/s connection is the specification that determines compatibility with the host controller and backplane. Dual-port controllers will not gain path redundancy from this drive. The 15000 RPM spindle speed and 300GB capacity are fixed characteristics of this model. Verify that the server accepts a 2.5-inch drive in a hot-plug carrier before purchase.

Domande su questo articolo
Which capacity of the HPE 431944-B21 should I choose for a high-transaction server?
The drive provides 300GB of storage on a SAS 3Gb/s interface, suited for enterprise workloads that demand fast, consistent access.
What does the 15000 RPM rating mean when the drive is installed in a server?
The spindle spins at 15000 RPM, delivering low latency and high IOPS for mission-critical applications that require rapid data retrieval.
How does the SAS 3Gb/s interface limit real-world throughput?
The SAS 3Gb/s link caps the maximum transfer rate at 3 gigabits per second, so sustained reads and writes cannot exceed that bandwidth.
