Height first: 7 mm, 9.5 mm or 15 mm

Thickness is the fit test that catches most buyers. Many laptops accept 7 mm or 9.5 mm drives, thin models take only 7 mm, and 15 mm drives, which carry the highest capacities, fit only bays designed for them, such as server drive bays and some external enclosures. A thinner drive usually fits a taller bay, with a spacer if needed, but not the reverse. Read the max height in the listing, or measure the drive you are replacing.

Then check the connector. SATA 6 Gb/s is standard on current laptops and also runs at the older 3 and 1.5 Gb/s speeds, so a newer drive works in an older SATA machine. Laptops from the IDE era need a 44-pin ATA drive, listed as IDE Ultra ATA100, which is a different connector entirely. SAS drives are for servers and need a SAS controller. Match the model number against your laptop's drive list when it is a branded machine.

Rotation speed, capacity and when an SSD is the smarter upgrade

Most laptop drives spin at 5,400 RPM, which keeps them quiet, cool and kind to battery life. 7,200 RPM models respond faster but run warmer and draw more power, and 10,000 or 15,000 RPM drives are SAS parts for servers. If speed is the goal rather than capacity, a 2.5-inch SSD fits the same bay and is a far bigger upgrade, while a hard drive makes sense for bulk capacity or a secondary bay.

Questions about 2.5-Inch Laptop Hard Drives: Height and Interface

What drive thickness does my laptop take?
Most laptops take 7 mm or 9.5 mm drives, and slim models only 7 mm. A 15 mm drive fits only bays built for it. Check the service manual or measure the old drive before choosing a replacement.
Can I fit a SATA drive in an older IDE laptop?
Not directly. IDE and SATA use different connectors and signalling, so laptops from the IDE era need a 44-pin ATA drive or a conversion adapter. Check which connector your laptop has before choosing.
Should I choose 5,400 or 7,200 RPM?
5,400 RPM drives are quieter, cooler and easier on battery life, and are plenty for storage. 7,200 RPM drives respond faster but run warmer. For general speed, an SSD is a larger gain than either.
