750GB 2.5" SATA Laptop Drive
The Western Digital WD7500BPKX is a 750GB 2.5-inch internal hard drive spinning at 7200 RPM with a SATA 6.0Gb/s interface and 16MB cache. It belongs to the WD Black series and is built for maximum performance in mobile workstations or high-end laptops. The bare drive measures 9.5mm in height, 69.85mm in width and 100.20mm in length. No mounting hardware, cables or documentation are included.
Suits performance-focused laptop upgrades
This drive suits users who need a 7200 RPM mechanical drive with a SATA 6.0Gb/s connection and 750GB of capacity. It is not for buyers who require a solid-state drive, a larger capacity than 750GB, a drive thinner than 9.5mm, or a different interface such as PCIe. Units may show cosmetic markings and up to 25 bad sectors, and they are sold erased to DoD 5220.22 M standard without formatting or partitioning.
9.5mm height decides fit
The single specification that decides compatibility is the 9.5mm maximum height, which must match the drive bay clearance of the target laptop. The 750GB capacity, 7200 RPM speed, SATA 6.0Gb/s interface and 16MB cache are fixed attributes of this model.

Questions about this item
Should I choose the 750GB capacity or a different size for my laptop?
This model provides 750GB of storage on a single 2.5-inch platter. If you need more space you would need a higher-capacity drive; if you need less, a smaller drive would cost less but the 750GB version is the only capacity offered for this WD Black WD7500BPKX.
What does the 7200 RPM spindle speed actually deliver in a laptop?
The 7200 RPM rotation reduces average latency and raises sustained transfer rates compared with slower notebook drives, so large files and boot sequences load noticeably quicker while the dual-processor controller keeps access times consistent.
What does the SATA 6.0Gb/s interface cap in practice?
The SATA 6.0Gb/s link tops out at 6.0Gb/s, but real-world throughput is limited by the 7200 RPM mechanical media and 16MB cache, so sequential reads typically peak well below the interface maximum.
