Questions about this item
Will the 5400 RPM spindle speed keep my laptop responsive for everyday tasks?
At 5400 RPM the average latency is 5.6 ms, which is typical for a 2.5 inch drive and keeps boot times and file loads steady for office work and web browsing.
What does the SATA 3.0 Gb/s interface actually limit on this drive?
The SATA 3.0 Gb/s link caps the burst transfer at 300 MB/s, while sustained reads and writes stay well below that because the 5400 RPM platters and 8 MB cache set the real throughput.
Does the 2.5 inch form factor fit every laptop drive bay?
The drive uses the standard 2.5 inch height for SATA notebook bays, so it slides into any laptop or enclosure designed for a 2.5 inch SATA hard drive.
