SSD Upgrades and Cloning

Replace a hard drive with an SSD without losing data.

In this lesson you will

  • Choose the right SSD
  • Clone or reinstall to the new drive

Key concepts

2.5-inch SATA and M.2cloningfresh installverification

The lesson

Check whether the computer takes a 2.5-inch SATA SSD or an M.2 SSD (SATA or NVMe) before buying.

Cloning copies everything to the new drive with cloning software; a fresh install with data restored is cleaner when the old system is cluttered.

Back up first, keep the old drive until the client confirms everything works and measure the improvement.

Step by step

  1. Identify the drive bay or slot.
  2. Back up the data.
  3. Clone to the SSD.
  4. Measure before and after.
Before and after

A slow office laptop before and after an SSD and RAM upgrade

The same laptop with a hard drive and 4 GB of RAM, then with an SSD and 8 GB (illustrative measurements).

Before

Hard disk drive and 4 GB RAM.

  • Start-up to usable desktop: about 2 minutes 40 seconds
  • Disk at 100% for several minutes after sign-in
  • Opening the accounting spreadsheet: about 25 seconds
  • User considering buying a new laptop

After

SATA SSD (cloned) and 8 GB RAM.

  • Start-up to usable desktop: about 25 seconds
  • Disk activity settles within seconds
  • Opening the same spreadsheet: about 4 seconds
  • Old drive kept for a week, then securely wiped

What changed and why

  1. The hard drive was the bottleneck; the SSD removed the waiting caused by its moving parts.
  2. Extra RAM stopped Windows swapping to disk when several programs were open.
  3. The upgrade cost a fraction of a new laptop and the computer still receives security updates, so upgrading was the right advice.

Practice activity

Upgrade the lab laptop to an SSD and record results.

Expected result: A faster laptop with measured improvement and data intact.
