Full disk space on a laptop is a problem that every user faces. System files, programs, games and media library take up more and more space, and free gigabytes are melting before our eyes. But don’t rush to delete important data or buy a new device! There are several proven methods expand memory on laptop, and many of them do not require deep technical knowledge.

In this article we will look at all the current methods - from upgrading your hard drive to optimizing existing space. You will learn how to replace HDD on SSD with a large volume, connect an external drive, use cloud services and even transfer some files to a flash drive. And also - how to avoid typical mistakes when working with laptop memory, so as not to lose data and damage the system.

1. Replacing the hard drive with a more capacious one: step-by-step instructions

The most radical, but also the most effective way is physical replacement of HDD/SSD for a model with a large volume. Modern laptops support drives up to 2–4 TB (depending on the model), and the transition from HDD on SSD will further speed up the system.

Before purchasing a new drive, check compatibility:

  • 🔍 Find out the current form factor: 2.5" (standard for laptops) or M.2 (for ultrabooks).
  • 📏 Determine thickness: usually 7 mm or 9.5 mm.
  • 🔌 Check the interface: SATA III (up to 600 MB/s) or NVMe (up to 3500 MB/s for PCIe 3.0).

To replace you will need: a screwdriver (usually Phillips #00), an antistatic wrist strap (optional, but recommended), and an external data cloning adapter. If you have never disassembled a laptop, watch the video instructions for your model - for example, for Lenovo ThinkPad or ASUS ROG the process may vary.

⚠️ Attention: Not all laptops allow you to easily replace the drive. In models with soldered memory (for example, some MacBook Pro or Dell XPS) upgrade is impossible without soldering. Check the specifications on the manufacturer's website!
Disk type Max. volume Reading speed Price for 1 TB
HDD (SATA) 5 TB 80–160 MB/s ~2500 ₽
SSD (SATA) 4 TB 500–550 MB/s ~6000 ₽
NVMe (PCIe 3.0) 2 TB 3000–3500 MB/s ~8000 ₽

After purchasing a new disk:

  1. Clone the data using Macrium Reflect or Clonezilla.
  2. Unplug the laptop and remove the battery (if removable).
  3. Remove the back cover and replace the drive following the instructions.
  4. Reinstall Windows or restore the system from a clone.

2. Using an external SSD/HDD: pros and cons

If you don't want to disassemble your laptop, external storage will be a great solution. Modern SSD in the body (for example, Samsung T7 or WD My Passport SSD) offer speeds up to 1000 MB/s through USB 3.2 Gen 2 and volume up to 2 TB.

Advantages of an external drive:

  • 🔄 Mobility: can be connected to other devices.
  • 🛠️ Simplicity: does not require disassembling the laptop.
  • 💾 Backup: automatic backups via Time Machine (macOS) or File History (Windows).

Disadvantages:

  • 🔌 Dependence on the USB port (may occupy a slot for a mouse or flash drive).
  • 🚫 Risk of loss or damage during transportation.
  • 🐢Speed lower than internal NVMe (but higher than HDD).

For maximum performance, choose external SSD with interface USB-C or Thunderbolt. For example, SanDisk Extreme Pro shows speed 1050 MB/s for reading, which is enough for editing videos or running games (if they support installation on an external drive).

3. Optimizing the current disk: cleaning and compression

Before you spend money on a new drive, try free up space on existing. Often users are unaware that tens of gigabytes are occupied by temporary files, caches and duplicates.

Cleaning methods:

  • 🧹 Built-in tools: Disk Cleanup (Windows) or Storage optimization (macOS).
  • 🗑️ Garbage removal: programs CCleaner, BleachBit or DaisyDisk (to visualize the occupied space).
  • 📂 Search for duplicates: Duplicate Cleaner or Gemini 2.
  • 🎮 Clearing game cache: in Steam go to Settings → Downloads → Clear cache.

For Windows it is also useful to disable hibernation (if you don't use it), since the file hiberfil.sys takes up several gigabytes. Do this via the command line:

powercfg /h off

On macOS, check the folder ~/Library/Containers — gigabytes of cache from applications can accumulate here. It’s also worth deleting old backups iPhone, which are stored in ~/Library/Application Support/MobileSync/Backup.

💡

If there is less than 10% free space left on the disk, Windows begins to slow down due to fragmentation. Run defragmentation regularly (for HDD) or optimization (for SSD) through dfrgui in the Run menu.

4. Transfer files to the cloud: Google Drive, OneDrive, Yandex Drive

Cloud storage is an ideal option for those who work with documents, photos or videos on multiple devices. Free plans offered 5–15 GB, and paid ones - up to 2 TB (For example, Google One for 699 ₽/month).

How to transfer data to the cloud:

  1. Install the client (Google Backup and Sync, OneDrive or Yandex Disk).
  2. Select folders to sync (for example, Documents or Images).
  3. Set up automatic photo uploading from your phone (this will free up space on your smartphone).
  4. Use Files on Demand feature (in OneDrive), so as not to download everything to disk.

Comparison of popular services:

Service Free Max. tariff Features
Google Drive 15 GB 2 TB (699 RUR/month) Integration with Google Docs, Gmail
OneDrive 5 GB 6 TB (includes Microsoft 365) "Personal Vault" for families (up to 6 users)
Yandex Disk 10 GB 1 TB (190 RUR/month) Bonuses for activity, built-in photo editor
⚠️ Attention: Do not store confidential data (passports, bank statements) in the cloud without encryption! Use Cryptomator or Boxcryptor to create encrypted folders.

5. Installing a second disk: if the laptop has a free slot

Many gaming and business laptops (eg. MSI GE76, HP Omen or Dell Latitude) have slot for second drive - usually M.2 2280. This allows you to install additional SSD without removing the main drive.

How to check slot availability:

  • 🔧 Use HWiNFO or AIDA64 to analyze the hardware configuration.
  • 📄 Look at the specifications on the manufacturer’s website (look for the section Storage).
  • 🔍 Disassemble the laptop and visually check for a free connector M.2.

If there is a slot, buy a compatible one NVMe SSD (For example, Crucial P5 Plus or Samsung 980 Pro) and install it:

  1. Turn off the laptop, disconnect the battery.
  2. Remove the back cover and find the slot M.2 (usually next to the main drive).
  3. Paste SSD at an angle 30° and secure with a screw.
  4. Turn on the laptop, format the new disk via Disk management (Windows) or Disk Utility (macOS).

After installation you can:

  • 📁 Move folders to a new drive Documents, Downloads or Games.
  • 🖥️ Install a second OS on it (for example, Linux for development).
  • 🎮 Use as a separate disk for projects or virtual machines.
How to move the Documents folder to another drive?

1. Open Explorer and right click on the folder Documents.

2. Select Properties → Location → Move.

3. Specify the path on the new drive (for example, D:\Documents).

4. Confirm the transfer - all files will be automatically copied.

6. Alternative methods: flash drives, SD cards and network storage

If the previous methods don't work, consider less obvious options:

1. USB flash drive as permanent storage

Modern flash drives (for example, SanDisk Ultra Fit) have a volume of up to 512 GB and almost never leave the port. They can be formatted as NTFS and use it like a regular disk. The downside is the limited rewriting resource (especially for cheap models).

2. SD card in expansion slot

Some laptops (eg. Microsoft Surface or Lenovo Yoga) have a slot for microSD. Maps SanDisk Extreme on 1 TB cost about 10 000 ₽ and are suitable for storing photos or music. Read/write speed - up to 160 MB/s.

3. Network Attached Storage (NAS)

Suitable for home use WD My Cloud or homemade NAS based on Raspberry Pi. This will expand the memory for all devices on the network. The downside is dependence on the Internet connection.

4. Optical discs (for archive)

If you want to save rarely used data (such as family videos), BD-R disks on 25–128 GB will become a reliable archive. Shelf life - up to 50 years.

💡

SD cards and flash drives are not suitable for installing programs or games - their read/write speed is 5–10 times lower than SSD. Use them only to store static files (photos, videos, documents).

FAQ: Frequently asked questions about expanding laptop memory

Is it possible to expand the memory on a laptop with a soldered SSD (for example, MacBook Air M1)?

No, in such models the disk is soldered to the motherboard, and it is impossible to replace it without special equipment. Alternatives:

  • Use external SSD with Thunderbolt (speed up to 2800 MB/s).
  • Optimize your current space (clearing cache, moving files to the cloud).
  • Buy an adapter OWC Envoy Pro FX - it allows you to connect NVMe like an external drive.
How to transfer Windows to a new SSD without reinstalling?

Use cloning programs:

  1. Connect new SSD through USB-SATA adapter.
  2. Run Macrium Reflect Free or EaseUS Todo Backup.
  3. Select the source drive and destination (SSD).
  4. Adjust sector alignment (4K for SSD).
  5. After cloning, replace the disks and boot from the new one SSD.

Important! If the new disk is larger than the old one, after cloning, expand the partition via Disk management.

How much free space should be on drive C for Windows to work properly?

Minimum requirements:

  • 20 GB — for basic work (but the system will slow down).
  • 50 GB - optimal for updates and temporary files.
  • 100+ GB - if you work with videos, games or virtual machines.

Windows 10/11 automatically backs up 7–10 GB for updates. If there is less space 10% depending on the disk capacity, the system begins to forcefully clear the cache and temporary files.

Can I use an external HDD for games?

Technically yes, but with caveats:

  • 🎮 Steam And Epic Games Allows you to install games on an external drive.
  • 🚫 Games with protection Denuvo (For example, Assassin’s Creed Valhalla) may not start with HDD due to low speed.
  • ⚡ For a comfortable game you need an external SSD with USB 3.2 Gen 2 (speed from 500 MB/s).

Best external SSD for gamers: Samsung T7 Shield, WD Black P50.

Which drive is better to choose for replacement: HDD or SSD?

Depends on the tasks:

Criterion HDD SATA SSD NVMe SSD
Speed 80–160 MB/s 500–550 MB/s 3000–3500 MB/s
Capacity up to 5 TB up to 4 TB up to 2 TB
Price for 1 TB ~2500 ₽ ~6000 ₽ ~8000 ₽
Reliability Shock sensitive No moving parts No moving parts
For whom Data archive, backups Daily tasks, office Gamers, video processing

Optimal for most users SATA SSD — it’s 3–5 times faster HDD and cheaper NVMe.
