Have you ever wondered why even after wiping the disk Windows persistently signals a lack of space on SSD? Modern laptops are equipped with 128–512 GB drives, but this is not enough: systems take up to 30 GB, games take up 100+ GB, and work files grow by leaps and bounds. Fortunately, increasing the memory on a laptop with SSD can be done in several ways - from budgetary to radical.

In this article we will look at all current memory expansion methods, including those that are silent about in official instructions: from replacing the disk with a more capacious one to hidden functions Windows 11, which will free up up to 20% of space. You'll learn how to choose a compatible NVMe or SATA SSD, what tools to use to clone a system, and why it is sometimes cheaper to buy an external drive than to upgrade the internal one. And also - a compatibility table for popular laptops and checklist for safe disk replacement.

1. Checking the current SSD: what can be improved?

Before you spend money on a new drive, make sure that this is the problem. Go to Explorer → This PC, right click on the disk C: and select Properties. Here you will see:

  • 📊 Total volume (for example, 237 GB out of 256 GB is normal, since part of the memory is reserved for service needs)
  • 🔄 File system (NTFS or ReFS - the first one takes up less space)
  • 🛠️ Data compression (if enabled, this already saves up to 10% space)

Also check the SSD connection type via Device Manager → Disk Devices. If the model name contains NVMe (For example, Samsung 980 Pro NVMe), which means the disk is using a high-speed interface PCIe. If only SSD without clarification - most likely it is outdated SATA III, and replacing it will give an increase not only in volume, but also in speed.

⚠️ Attention: On laptops with Optane Memory (technology Intel for HDD acceleration), replacing an SSD may result in loss of this function. Check in BIOS (section Advanced → Storage Configuration), is it enabled Optanebefore changing anything.
📊 What size SSD do you have now?
  • 128–256 GB
  • 256–512 GB
  • 512 GB–1 TB
  • More than 1 TB

2. Method 1: Optimizing your existing SSD (without buying a new one)

If the free space is less than 10% of the total volume, Windows starts to slow down - the system uses the SSD for cache and temporary files. Here's how to free up up to 30GB free:

  • 🧹 Cleaning system junk: run Disk Cleanup (type in search Windows), check the boxes Temporary files, Cart, Update log files.
  • 🗑️ Deleting old restore points: In the same cleanup window, go to the tab Additionally and press Clear in section System Restore.
  • 🎮 Transferring games and programs: in Steam or Epic Games you can specify another drive for installation (even an external one) HDD). To do this, create a folder, for example, D:\Games, and in the launcher settings select it as the installation location.

For deep cleaning, use utilities like CCleaner (free version) or built-in command:

Dism /Online /Cleanup-Image /AnalyzeComponentStore

It will show how much space the update backups take up Windows. If more than 5 GB, run:

Dism /Online /Cleanup-Image /StartComponentCleanup /ResetBase
💡

B Windows 11 there is a hidden function CompactOS, which compresses system files without losing performance. Run Command line as administrator and enter compact.exe /compactOS:always. This will free up 2-4 GB.

3. Method 2: Replacing the SSD with a more capacious one

If optimization doesn't help, it's time to think about a replacement. Modern laptops support NVMe SSD form factor M.2 2280 (22 mm width, 80 mm length). Here's how to choose the right drive:

Parameter Budget option Optimal choice Premium class
Capacity 512 GB 1 TB 2 TB+
Interface SATA III (up to 550 MB/s) PCIe 3.0 x4 (up to 3500 MB/s) PCIe 4.0 x4 (up to 7000 MB/s)
Models Kingston A400, Crucial BX500 Samsung 980, WD Black SN770 Samsung 990 Pro, Seagate FireCuda 530
Price (2026) from 3,000 ₽ from 6,000 ₽ from 12,000 ₽

Please check compatibility with your laptop before purchasing. For example, Lenovo ThinkPad T14 supports PCIe 4.0, and Acer Aspire 5 - only PCIe 3.0. You can clarify this:

  • 🔍 In the official documentation (search by model + "storage specifications").
  • 🛠️ Through the utility HWiNFO (tab Drives).
  • 💬 On forums (for example, NotebookCheck or Reddit).
⚠️ Attention: Some laptops (eg. Apple MacBook Air M1/M2 or Dell XPS 13 9310) The SSD is soldered to the motherboard. It is impossible to replace it - you just need to buy an external drive.

Make a backup copy of your data (via Macrium Reflect or Clonezilla)

Buy a new SSD with a capacity reserve (+20% of the current one)

Prepare a screwdriver Torx T5 or Phillips #00 (depending on model)

Disconnect the laptop from the network and remove the battery (if removable)

Download bootable USB flash drive from Windows (in case of problems with cloning) -->

4. Method 3: Cloning the system to a new SSD

Transfer Windows and all programs to the new disk - a critical step. Errors here can lead to data loss or blue screen (BSOD). Use these tools:

  • 🖥️ Macrium Reflect Free - simple interface, supports UEFI And GPT.
  • 🐧 Clonezilla - free, but requires knowledge of commands (suitable for Linux).
  • 💿 Samsung Data Migration - only for disks Samsung, but automatically selects the settings.

Step-by-step instructions for Macrium Reflect:

  1. Connect the new SSD via USB-SATA adapter or install it in the second slot (if available).
  2. Run Macrium Reflect, select current drive C: and press Clone this disk.
  3. Specify the new SSD as the target, check the box Sector by sector copy (if you need to copy everything, including empty space).
  4. Click Next and wait for completion (may take 1-3 hours depending on the volume).
  5. After cloning unplug the old SSD and boot from the new one.

If after cloning Windows does not start, check:

  • 🔌 Is the new SSD connected to the same slot as the old one (some laptops prioritize certain connectors).
  • 🔧Settings BIOS: turn on AHCI for SATA or NVMe Support for PCIe.
  • 🖥️Loading order: in Boot Menu (usually called F12 or Esc) select the new drive.
What to do if the new SSD is not detected in the BIOS?

1. Check if it is installed correctly (sometimes you need to press it with force).

2. Update BIOS to the latest version (download from the laptop manufacturer’s website).

3. Try a different slot M.2 (if there are several of them).

4. If the disk is still not visible, it may be incompatible with your laptop controller (for example, PCIe 4.0 SSD in slot PCIe 3.0).

5. Method 4: Using a second SSD (if there is a free slot)

Many laptops (eg. ASUS ROG Zephyrus or MSI GS66) have a second slot M.2 for additional storage. This is ideal if you need both speed and volume. Here's how to connect a second SSD:

  1. Remove the bottom cover of the laptop (look for "maintenance manual" in the instructions).
  2. Find the second slot M.2 - it is usually closed with a metal lid or thermal pad.
  3. Place the SSD at an angle of 30° and gently press until it clicks (do not force it!).
  4. Secure the drive with the screw (included with your laptop or SSD).

After installation:

  • 🖥️ Go to Disk management (Win + X → Disk Management).
  • 🔄 Find a new disk (it will be marked as "Unallocated").
  • 📁 Right click and select Create a simple volume, then format to NTFS.

Now you can:

  • 🎮 Transfer games and programs to the second disk (in Steam this is done through Settings → Downloads → Steam folders).
  • 📂 Store backups or media files on it.
  • 🔧 Use as a cache for video editing (in Adobe Premiere specify the path to the disk in the settings Media Cache).
⚠️ Attention: In laptops with RAID array (for example, some models Dell Precision) adding a second SSD may reset the configuration. Disable before installation RAID in BIOS (section Storage Configuration → SATA Operation).

6. Method 5: External SSD - an alternative to internal replacement

If your laptop does not have free slots or the SSD is soldered, an external drive will be a lifesaver. Modern USB-C SSD (For example, Samsung T7 Shield or SanDisk Extreme Pro) give speeds of up to 1000 MB/s - this is enough for:

  • 🎮 Launch games (via Steam Library Folders or Xbox Game Pass).
  • 🎬 Video editing in 4K (if connected via Thunderbolt 3/4).
  • 📁 Backup storage (with automatic encryption via BitLocker).

How to choose an external SSD:

Criterion Recommendations
Interface USB 3.2 Gen 2x2 (20 Gbit/s) or Thunderbolt 3 (40 Gbps)
Capacity 1–2 TB (for games and media), 500 GB (for documents)
Protection IP65 (dust/moisture resistant) and rubber bumper (eg Samsung T7 Shield)
Speed From 500 MB/s (for office tasks) to 2000 MB/s (for professional use)

For maximum speed, connect an SSD to the port USB-C with logo Thunderbolt (lightning ⚡). If there is no such thing, use USB 3.2 (usually marked in blue).

💡

External SSD on Thunderbolt 3 can work faster than internal SATA SSD! For example, SanDisk Extreme Pro shows 1050 MB/s versus 550 MB/s SATA III.

7. Method 6: Cloud storage as an addition to SSD

If it is physically impossible to increase memory, transfer some of the data to the cloud. Services like Google Drive, OneDrive or Yandex Disk offer from 5 to 15 GB for free, and paid plans cost from 100 ₽/month for 100 GB. How it works:

  • 📁 Files on request (OneDrive): files are stored in the cloud, but are displayed in Conductor. When opened, they are downloaded automatically.
  • 🔄 Automatic synchronization: folders Documents, Images And Desk can be transferred to the cloud (in settings OneDrive → Backup).
  • 🎬 Streaming video: Google Photos allows you to store videos in original quality (up to 15 GB for free).

Suitable for professionals:

  • 💼 Dropbox (integration with Adobe Creative Cloud).
  • 🛡️ pCloud (client side encryption).
  • 📊 Amazon S3 (for large amounts of data, from 1 TB).
⚠️ Attention: Do not store files that you edit frequently (for example, projects) in the cloud Photoshop or database). Constant synchronization eats up traffic and slows down work.

8. Method 7: Upgrade from HDD to SSD (for old laptops)

If your laptop is still running on HDD (For example, Seagate Barracuda or WD Blue), replacing with SSD will give not only an increase in volume, but also:

  • ⚡ Speed up loading Windows from 1–2 minutes to 10–15 seconds.
  • 🖱️ Instant launch of programs (for example, Photoshop will open in 2 seconds instead of 20).
  • 🔋 Increased battery life (SSD consumes 5 times less energy than HDD).

How to choose an SSD to replace an HDD:

  1. Check form factor:
    • 2.5" SATA III - for most laptops (for example, Lenovo IdeaPad, HP Pavilion).
    • M.2 SATA - for ultrabooks (for example, Acer Swift 3).
  2. Define thickness:
    • 7mm is the standard for most laptops.
    • 9.5 mm - for some models Dell or Toshiba.
  3. Select capacity:
    • 256 GB - minimum for Windows + office programs.
    • 512 GB – optimal for games and multimedia.
    • 1 TB - if you store large files (video, RAW photos).

To clone a system with HDD on SSD use the same tools as in Method 3, but keep in mind:

  • 🔄 If the new SSD less in volume than the old one HDD, first clean the disk to a size that will fit on the SSD.
  • 🛠️ After cloning, check the partition alignment (should be 4K-aligned). This can be done through MiniTool Partition Wizard.
💡

Replacing an HDD with an SSD is the most cost-effective upgrade for an old laptop. In terms of price/performance ratio, it surpasses even a RAM upgrade.

FAQ: Frequently asked questions about increasing SSD memory

Is it possible to install two SSDs in a laptop if there was only an HDD?

Yes, if the laptop has a slot M.2. For example, in Lenovo Legion Y540 or HP Omen 15 can be installed NVMe SSD in M.2-slot and leave HDD on the spot. The main thing is to check in the documentation whether the motherboard supports such a configuration.

Why did the laptop start to get hotter after replacing the SSD?

It's normal for NVMe SSD, especially high speed models (e.g. Samsung 980 Pro or WD Black SN850X). They heat up to 70°C under load. Solutions:

  • Install a thermal conductive pad between the SSD and the laptop cover.
  • Update BIOS - Some manufacturers add power management for SSDs.
  • Disable TurboWrite (technology Samsung to speed up recording) in a proprietary utility Samsung Magician.

How to transfer Windows to SSD without losing activation?

Activation Windows tied to the motherboard, not the disk. Therefore, when cloning or clean installing on a new SSD, the license will be saved automatically if:

  • Are you using digital license (linked to account Microsoft).
  • The laptop initially came with pre-installed Windows (the license is included in BIOS).

If after replacing the SSD the system asks to activate, go to Settings → Update & Security → Activation and press Troubleshooting.

Is it worth buying an SSD larger than 2 TB for a laptop?

Depends on the tasks:

  • 🎮 For gamers: yes, if you play Call of Duty: Warzone (150+ GB), Microsoft Flight Simulator (200+ GB) or store many projects in Unreal Engine.
  • 🎬 For video editing: 2 TB is enough for 10–20 hours of video 4K (including proxy files).
  • 💼 For office: 1 TB is enough - a larger volume will only increase the cost without real benefit.

Please note that SSDs with a capacity of 4 TB or more (for example, Samsung 870 QVO 4TB) may be slower to write due to usage QLC memory.

Can I use a PlayStation 5 SSD in a laptop?

Technically yes, but there are some nuances:

  • 🔧 PS5 requires PCIe 4.0 NVMe SSD with read speed from 5500 MB/s. Such disks (WD Black SN850X, Seagate FireCuda 530) compatible with laptops Intel 11th generation or AMD Ryzen 5000/6000.
  • 🔥 In a laptop, such an SSD will heat up more due to the lack of a heatsink (in PS5 it is built into the slot).
  • 💰 The price for these models is higher than for “laptop” SSDs, so it is more profitable to buy a specialized drive.
