Lenovo ThinkPad 500GB 7200 RPM SATA Drive
This 2.5-inch internal hard drive delivers 500GB of storage for ThinkPad laptops. It spins at 7200 RPM with a 16MB cache and a SATA 3.0Gb/s interface. The 9.5-mm height fits standard drive bays in compatible notebooks. Buyers who need more capacity should consider a different drive.
SATA 3.0Gb/s Interface Practical Limits
The SATA 3.0Gb/s link caps sequential throughput at 3.0 gigabits per second. Mechanical latency averages 4.2ms with a 12ms seek time. The 512-byte sector format and no-ID recording keep overhead low. Systems limited to slower SATA revisions will bottleneck this drive.
Verify 2.5-Inch Bay And SATA Connector
Confirm your laptop accepts a 2.5-inch, 9.5-mm high drive before ordering. Ensure the motherboard provides a SATA data and power connector for 3.0Gb/s operation. The drive uses a rotary voice coil actuator and load/unload head technology. Older chassis with only PATA or mSATA slots cannot use this unit.

Questions about this item
Is the 500GB capacity sufficient for a primary laptop drive?
The 500GB capacity provides ample space for the operating system, applications, and a large collection of documents or media files on a single 2.5-inch drive.
How does the 7200 RPM speed affect real-world performance?
The 7200 RPM spindle speed combined with 12ms average seek time and 4.2ms latency delivers quicker boot times and faster application launches than slower-spinning drives.
What does the SATA 3.0Gb/s interface limit in practice?
The SATA 3.0Gb/s interface caps the maximum theoretical transfer rate at 3.0Gb/s, so sustained read and write speeds cannot exceed that bandwidth ceiling.
