How to increase memory on a laptop: a complete guide to replacing a hard drive with an HDD or SSD

Has your laptop started to slow down due to lack of space? Files do not fit, and the system issues warnings about the disk being full? Expanding your memory is one of the most effective upgrades you can do yourself. Unlike replacing a processor or video card, upgrading a drive does not require deep technical knowledge, but has its own nuances.

In this article we will look at all the ways to increase memory: from replacement HDD to SSD (which will give a speed increase of 5-10 times) before adding a second disk or using external drives. Let's consider SATA, M.2 NVMe and hybrid solutions, and will also give specific recommendations on choosing models for different budgets. Let us dwell separately on cloning a system without losing data - a critical stage where many make mistakes.

1. How to determine which drive is installed in a laptop

Before you buy a new drive, you need to understand what's already in your device. This determines the choice of a compatible drive. There are three main types:

• 🔹 HDD (hard drive) - a traditional mechanical drive with platters. Typically form factor 2.5" (for laptops) or 3.5" (for PC). Read/write speed: 80-160 MB/s.
• 🔹 SATA SSD - solid state drive with interface SATA III. Form factor 2.5", speed 500-550 MB/s. Compatible with most laptops.
• 🔹 M.2 NVMe SSD - a modern high-speed drive connected directly to the motherboard. Speed ​​from 1500 to 7000 MB/s. Comes in sizes 2242, 2260, 2280 (numbers indicate length in mm).

To find out the current configuration:

1. Click Win + R, enter msinfo32 and find the "Disk" line in the "Computer" section.
2. Use the utility CrystalDiskInfo (shows model, interface, disk health).
3. Physically inspect the drive: open the back cover of the laptop (usually secured with 1-2 screws) and check for a slot M.2 or 2.5" compartment

⚠️ Attention: In some ultrabooks (for example, MacBook Air or Dell XPS) the drive is soldered to the motherboard. In this case, replacement is impossible without specialized equipment.

2. Which drive to choose for replacement: HDD, SATA SSD or NVMe

The choice depends on your budget, laptop model and purpose of use. Below is a comparison table of key parameters:

Recommendations for selection:

• 💰 Budget up to 5,000 ₽: Take it SATA SSD (For example, Crucial MX500 or Samsung 870 EVO). Optimal price/quality ratio.
• 🚀 Maximum speed: NVMe (For example, WD Black SN850X or Samsung 980 Pro). Suitable for gaming, video editing, and working with large files.
• 🗃️ Need a lot of space cheap: HDD for 2-4 TB (for example, Seagate Barracuda or WD Blue). Relevant for storing archives, photos, videos.

3. Step-by-step instructions: how to replace a disk in a laptop

The disk replacement process consists of 4 stages: preparation, physical replacement, system cloning (or clean installation of the OS) and configuration. Let's look at each step in detail.

3.1. Preparing Tools and Backing Up

You will need:

• 🔧 Phillips screwdriver (usually PH0 or PH1).
• 💽 External drive or flash drive (minimum 16 GB) for backup.
• 🖥️ Cloning program (for example, Macrium Reflect, Clonezilla or AOMEI Backupper).
• 🔌 Antistatic bracelet (optional, but recommended for protection against static electricity).

Important: if you are cloning a system, the size of the new disk must be no lessthan the old one. For example, if on the old HDD 300 GB occupied, new SSD should be at least 320-350 GB.

3.2. Physical disk replacement

Algorithm of actions:

1. Turn off the laptop, disconnect the charger and remove the battery (if it is removable).
2. Turn the laptop over and remove the screws on the back cover. In some models (for example, Lenovo ThinkPad) the disk is removed through a separate hatch.
3. Carefully remove the old drive by pulling the plastic tab or disconnecting SATA- connector For M.2 unscrew the fixing screw.
4. Install the new drive in reverse order. For HDD/SSD 2.5" use the original slide or adapter.

3.3. Cloning the system to a new disk

The most reliable way to transfer a system is cloning. Let's look at the process using an example Macrium Reflect Free:

1. Connect the new drive via USB-SATA adapter or install it in the second slot (if available).
2. Run Macrium Reflect, select the old disk and click "Clone this disk".
3. Specify the new disk as the target, select the "Sector by sector copy" option (if you want to copy all sectors) and start the process.
4. Once complete, disconnect the old drive and boot from the new one.

⚠️ Attention: If the system does not boot after cloning, check:

• Load order in BIOS (click F2/Del at start).
• Operating mode SATA-controller (must be AHCI, not IDE).
• Integrity of the boot sector (restore using the Windows installation flash drive).

4. How to add a second drive to a laptop (if there is a free slot)

Many laptops (eg. ASUS ROG, MSI Gaming or HP Pavilion) have an additional slot M.2 or room for a second one 2.5" disk. This allows you to set SSD for the system and leave HDD for files.

Check compatibility:

• 🔍 Look under the back cover - there is often a free slot M.2 labeled as "Wi-Fi/SSD".
• 📄 Study the model specifications on the manufacturer’s website (look for the lines “Storage expansion” or “M.2 slot”).
• 🛠️ Use the utility HWiNFO — it will show all available slots and their supported protocols (SATA or PCIe).

If there is a slot, the installation algorithm is:

1. Buy the right one M.2 SSD (For example, Kingston KC3000 for PCIe 4.0 or Crucial P5 Plus for PCIe 3.0).
2. Insert the drive into the slot at a 30° angle and secure with a screw.
3. Turn on your laptop, go to BIOS and check that the disk is detected.
4. Initialize the disk via Disk management (Win + X → Disk Management).

5. Alternative ways to increase memory without replacing the drive

If disk replacement is not possible (for example, in MacBook or thin ultrabooks), consider these options:

• 🖥️ External SSD/HDD: Connect via USB 3.0/3.1 or Thunderbolt. Modern exterior NVMe (For example, Samsung T7 Shield) give speeds up to 1000 MB/s.
• ☁️ Cloud storage: Google Drive, Yandex Disk or Mega offer up to 15-50 GB for free. Suitable for photographs Amazon Photos (unlimited space for pictures).
• 🔄 Optimizing the current drive:
  • Delete temporary files via Disk Cleanup (Win + R → cleanmgr).
  • Disable hibernation (saves up to 10 GB):

    powercfg /h off

  • Move the swap files to another drive (if you have one).
• 🔧 Replacing a DVD drive with an HDD/SSD: In some laptops (for example, Dell Latitude or HP ProBook) you can remove the drive and install a second drive instead via an adapter caddy.

For external drives we recommend:

6. Common mistakes when replacing a disk and how to avoid them

Even experienced users sometimes make mistakes that lead to data loss or system failure. Here are the most common:

• 🔌 Battery not disconnected: When working with hardware, always remove the battery (if it is removable) and turn off the charger. Static electricity can damage the motherboard.
• 🔄 Incorrect SATA mode in BIOS: If after replacing with SSD The system does not boot, check that BIOS mode enabled AHCI (not IDE or RAID).
• 📁 Cloning to a smaller disk: If new SSD smaller than old HDD, cloning will fail. Solution: First, shrink the partition on the old drive to match the size of the new one.
• 🔧 Incorrect fixation of M.2 SSD: The drive should fit tightly, without play. If the screw is loosely tightened, over time the contacts will oxidize and the disk will no longer be detected.
• 🔄 No backup: Even if you clone a drive, make a separate copy of important files to an external drive. Cloning programs sometimes fail.

7. Optimizing the new disk after installation

Easy system transfer to SSD does not guarantee maximum performance. To keep the drive running at full capacity, follow these steps:

• 🔧 Enable TRIM: This feature prolongs life SSD, optimizing data recording. Check that it is active:

  fsutil behavior query DisableDeleteNotify

  If the result 0 — TRIM is enabled. If 1, activate with the command:

  fsutil behavior set DisableDeleteNotify 0

• 🚫 Disable defragmentation for SSD: Not only is it useless, but it also reduces the life of the drive. B Disk optimization (Win + R → dfrgui) disable automatic defragmentation for SSD.
• 📁 Transfer temporary files to HDD: If you have two drives, reconfigure your environment variables TEMP And TMP:
  1. Open System Properties → Advanced Settings → Environment Variables.
  2. Change the paths for TEMP And TMP to folder to HDD (For example, D:\Temp).

For NVMe additionally:

• Update the disk firmware (download from the manufacturer’s website).
• B BIOS turn on PCIe 4.0 (if supported).
• Install the driver NVMe from the manufacturer (for example, Samsung NVMe Driver for 980 Pro).
