Small silver 2.5-inch SAS enterprise hard drive with dual ports

HP

HP 507127-B21 300GB 10000 rpm SAS 2.5-inch device server

SKU CH-NKB1-ER9T9

300 GB 10 000 rpm SAS 2.5-inch enterprise hard drive with dual-port 6 Gb/sec interface for ProLiant servers and storage arrays

  • 300 GB capacity supports dense storage in 2.5-inch bays
  • 10,000 rpm spindle speed accelerates transaction-heavy workloads
  • 6 Gb/sec SAS interface enables high-throughput data transfers
  • 0 ms average seek time reduces latency for random I/O
  • Dual-port SAS design provides redundant paths for enterprise availability

HP 300GB 10K SAS Enterprise Drive

The HP 507127-B21 is a 300GB 10000 rpm SAS hard drive in a 2.5-inch form factor. It uses a dual-port 6 Gb/sec SAS interface for enterprise storage arrays. The drive is built for high-transaction workloads where data integrity and availability are critical. It is supplied new for compatible HP ProLiant and storage systems.

Suited for ProLiant servers needing 300GB 10K

This drive fits administrators maintaining existing ProLiant DL, ML, BL or SL servers that require 300GB 10K SAS capacity. It also matches HP D2700, MSA and X-series enclosures listed in the compatibility data. Buyers who need larger capacities or solid-state performance should look at other options. The 6 Gb/sec SAS interface limits use to controllers and backplanes that support that speed.

300GB capacity with 10K rotational speed

The 300GB capacity handles operating-system volumes, database logs and high-IOPS transaction data. Average seek time of 4.0 ms and full-stroke seek of 7.45 ms provide consistent response for random workloads. The 10000 rpm spindle delivers sustained throughput for sequential reads and writes. Capacity runs out when datasets exceed 300GB or when workloads demand SSD-level latency.

Highlights

  • 300 GB capacity supports dense storage in 2.5-inch bays
  • 10,000 rpm spindle speed accelerates transaction-heavy workloads
  • 6 Gb/sec SAS interface enables high-throughput data transfers
  • 0 ms average seek time reduces latency for random I/O
  • Dual-port SAS design provides redundant paths for enterprise availability

Questions about this item

What SAS controller or backplane is required to run this 6 Gb/sec dual-port drive?

A 6 Gb/sec SAS HBA, RAID controller, or backplane with dual-port support is needed to utilise the full transfer rate and failover capability of this drive.

Will this 10,000 rpm 2.5-inch SAS drive work in my older ProLiant DL360 G5 or DL380 G4 server?

Yes, the drive is listed as compatible with ProLiant DL360 G4p, G5, G6, G7 and DL380 G4, G5, G6, G7 models.

How can I verify the drive is performing at its rated 6 Gb/sec link speed after installation?

Check the negotiated link rate in the SAS controller BIOS, HBA utility, or OS storage tools; it should report 6 Gb/sec for each of the two ports.
