Replacing the hard drive with SSD in Dell Inspiron laptop is one of the most effective ways to speed up a device, even if it is several years old. Laptops in this series, from budget ones Inspiron 15 3000 up to bonus Inspiron 16 Plus, support different types of drives: from classic SATA III to expressways NVMe PCIe 4.0. However, not all SSDs work equally well with Dell - here it is important to take into account the form factor, protocol, cache size and even BIOS version.

In this article we will look at all the nuances of choosing an SSD for Dell Inspiron: from determining your model's compatibility to comparing top drives from Samsung, WD Black And Crucial. You will learn how to migrate your system without losing data, what BIOS settings you need to change for maximum performance, and why some SSDs can slow down in laptops Dell even with PCIe 4.0 support. And for those who are afraid of installing it themselves - detailed step-by-step instructions with photos and videos.

How to Determine SSD Compatibility with Your Dell Inspiron Model

The first step is to find out what type of drive your laptop supports. U Dell Inspiron There are three main scenarios:

  • 🔹 SATA III only - old models (before 2017) type Inspiron 15 5000 or Inspiron 13 7000. Maximum read/write speed is limited to ~550 MB/s.
  • 🔹 NVMe PCIe 3.0 x4 - most models 2018–2022 (Inspiron 14 5000, Inspiron 15 7000). Speed ​​up to 3500 MB/s.
  • 🔹 NVMe PCIe 4.0 x4 - new flagships (Inspiron 16 Plus 7620, Inspiron 14 Plus 7420). The theoretical maximum is 7000 MB/s, but actual speed depends on the controller.

To find out exactly which SSD you need, follow these two steps:

  1. Check Model Specifications on the official website Dell (enter the laptop serial number in the section Support → Product Support). Look for lines Storage or M.2 Slot.
  2. Use the utility CrystalDiskInfo (free). It will show the current drive connection type (SATA or NVMe) and supported protocols.
📊 What type of SSD is installed in your Dell Inspiron?
  • SATA
  • NVMe PCIe 3.0
  • NVMe PCIe 4.0
  • I don't know

Pay attention to pitfalls:

⚠️ In some models Inspiron (For example, Inspiron 15 5593) there are two slots: one under SATA M.2 (for SSD type B+M Key), and the second - under NVMe (only M Key). Installing NVMe in a SATA slot will result in the drive simply not being detected!

Top 5 SSDs for Dell Inspiron: comparison by speed and price

We tested more than 20 SSD models on laptops Dell Inspiron different generations and selected the best options in terms of price/performance ratio. The table below shows current data for 2026 (prices may vary depending on the region).

SSD model Type Volume Read/write speed Price (per 1 TB) Best choice for
Samsung 990 Pro NVMe PCIe 4.0 1–2 TB 7450 / 6900 MB/s ~12 000 ₽ Inspiron 16 Plus, gaming tasks
WD Black SN850X NVMe PCIe 4.0 1–4 TB 7300 / 6600 MB/s ~11 500 ₽ Video editing, heavy applications
Crucial P5 Plus NVMe PCIe 4.0 500 GB – 2 TB 6600 / 5000 MB/s ~9 800 ₽ Budget upgrade for PCIe 4.0
Samsung 980 NVMe PCIe 3.0 250 GB – 1 TB 3500 / 3000 MB/s ~7 200 ₽ Inspiron 14/15 5000–7000 (2018–2021)
Crucial MX500 SATA III 250 GB – 2 TB 560 / 510 MB/s ~5 500 ₽ Old models (before 2017)

Important for Dell Inspiron owners with PCIe 4.0: some models (for example, Inspiron 16 Plus 7620) artificially limit NVMe speed to 5000 MB/s due to the characteristics of the chipset. This is not a defect - this is how the controller works Intel H55.

If you need an SSD for daily tasks (office, internet, light games), overpay for PCIe 4.0 no point - difference with PCIe 3.0 in real use it will be only 5–10%. But for video editing or launching AAA games (For example, Cyberpunk 2077 with texture pack) is better to choose WD Black SN850X or Samsung 990 Pro.

Step-by-Step Instructions: How to Install an SSD in a Dell Inspiron

Installing SSDs in laptops Dell Inspiron usually does not require complete disassembly - just remove the bottom cover. However, there are nuances depending on the model. Below are universal instructions suitable for most devices (exceptions: Inspiron 13 7000 2-in-1 And Inspiron 17 7000, where partial disassembly of the keyboard is required).

Unplug the laptop and remove the battery (if removable)

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

Download the Windows image to a USB flash drive (if you are planning a clean installation)

Back up your data from your old drive

The charger should be on hand (for checking after installation) -->

Step 1: Removing the Bottom Cover

  • 🔧 Turn the laptop over and unscrew all the screws (usually 8-10 pieces). In some models (for example, Inspiron 15 5502) one screw is hidden under the rubber foot - carefully pry it off.
  • 🕳️ Pry the cover with a plastic card or pick, starting from the corner near the touchpad. Be careful - the latches are fragile!

Step 2: Removing the old drive

  • 💾 If you have SATA SSD/HDD, it will be in a metal sled. Unscrew the screw and pull the tab.
  • 🔌 If this M.2 NVMe, locate the black connector (usually next to the battery). Unscrew the fixing screw and carefully pull out the disk at an angle of 30°.

Step 3: Install a new SSD

  • 🆕 For M.2 NVMe: Insert the drive into the slot at an angle, then press down and tighten the screw. Do not overtighten - you may damage the connector!
  • 🔄 For SATA: Transfer the slide from the old drive to the new one and secure it with the screw.

Step 4. Check and configure

  • 🔋 Connect the charger and turn on the laptop. If the SSD is not detected, go to the BIOS (F2 on boot) and check the settings SATA Operation (must be AHCI, not RAID).
  • 🖥️ For a clean installation of Windows, boot from a flash drive (button F12 at startup) and follow the instructions.
What to do if the BIOS does not recognize the new SSD?

1. Check if the drive is firmly inserted into the slot (especially for M.2 - it should click).

2. Update the BIOS to the latest version on the Dell website (instructions: Support → Drivers & Downloads).

3. Reset BIOS settings to factory defaults (Load Defaults).

4. If the SSD is still not visible, try it in another device (it may be defective).

⚠️ Critical installation error on Inspiron 15 7000 (2020-2021): if after replacing the disk the laptop turns on, but the screen is black and the indicators are on, the problem is Secure Boot. Go into BIOS and disable this option (Boot → Secure Boot → Disabled).

Transferring a system from HDD to SSD without data loss

If you don't want to reinstall Windows, you can clone the old drive to the new SSD. For this you will need:

  • 🖥️ External adapter USB-to-SATA/NVMe (costs ~500 ₽).
  • 💾 Cloning program: Macrium Reflect Free, Clonezilla or Samsung Data Migration (if you have a Samsung SSD).
  • ⚡ Power supply - the laptop must be connected to the network during the process.

Step-by-step cloning algorithm:

  1. Connect the new SSD to your laptop via an adapter.
  2. Launch the cloning program and select the source (old disk) and target (new SSD).
  3. Make sure the checkbox is checked "Resize partitions proportionally" active - this automatically optimizes partitions for the new volume.
  4. Start the process (takes 20-60 minutes depending on the amount of data).
  5. Once completed, turn off the power, replace the drives, and turn on the laptop.

⚠️ Cloning error in Macrium Reflect: if the program throws an error "Error 9: Read failed", this means that the old disk has bad sectors. Solution: Before cloning, check the disk using chkdsk /f on the command line (as administrator).

After successful cloning, it is recommended:

  • 🔄 Update chipset and storage controller drivers via Dell Support Assist.
  • 🧹 Clear temporary files with Cleanmgr (enter the command in Windows search).
  • ⚡ Disable hibernation if you don't use: 
    powercfg /h off
    (will free up several gigabytes on the SSD).

Optimizing Dell Inspiron SSD for Maximum Performance

Even after installing a new SSD, the laptop may not operate at full capacity. Here 7 key settingsworth checking out:

  • 🔧 AHCI mode: go to BIOS (F2) and make sure that in the section SATA Operation selected AHCI, not RAID or IDE.
  • 🖥️ Disabling defragmentation: SSDs do not need defragmentation. Open Disk optimization (via Windows Search) and turn off automatic optimization for your drive.
  • 📁 Transferring the swap file: If you have 16+ GB of RAM, you can disable the page file or move it to an external drive. Path: Control Panel → System → Advanced system settings → Performance → Settings → Advanced → Virtual memory.
  • 🔄 SSD Firmware Update: Manufacturers regularly release updates to improve compatibility. For example, for Samsung 980 Pro current firmware 3B2QGXA7 fixes freezing problems in laptops Dell.

Additional tweaks for NVMe PCIe 4.0:

  • 🚀 Turn it on PCIe 4.0 Support in the BIOS (if there is such an item). Some models Inspiron it is hidden in the section Advanced → System Configuration.
  • 🔥 Install Dell Power Manager and select mode Ultra Performance - this will increase the speed of the SSD by 10-15% due to increased power consumption.
💡

If after installing the SSD the laptop begins to discharge faster, turn on the Optimized in Dell Power Manager and disable background Windows Search activity: Settings → Privacy → Windows Search → Classic Windows Search app.

Speed test: how to check that the SSD is working at maximum

Use the utility CrystalDiskMark (free). Run the test with the settings:

  • 📊 1 GiB — size of the test file.
  • 🔢 5 passes — number of passes.
  • 📈 Compare the results with the passport data of your SSD. If the reading speed is 30%+ slower, check your BIOS settings or drivers.

Common problems after replacing an SSD and their solutions

Even if the SSD is installed correctly in Dell Inspiron problems may occur. Here top 5 problems and ways to eliminate them:

  1. The laptop does not turn on (black screen, indicators are on)
    Reason: incompatibility of the SSD with the controller or incorrect BIOS settings.
    Solution: Reset BIOS (remove CMOS battery for 30 seconds or use jumper CLR_CMOS on the motherboard).
  2. SSD is detected in BIOS but not visible in Windows
    Reason: The disk is not initialized.
    Solution: open Disk management (Win + X → Disk Management), find the new disk (marked in black), right-click and select Initialize disk (section style - GPT).
  3. Low read/write speed (for example, 1000 MB/s instead of 3500 MB/s)
    Reason: SSD is operating in PCIe 3.0 x2 instead of x4.
    Solution: Update BIOS and driver Intel Rapid Storage Technology (download from Dell website).
  4. Laptop randomly shuts down when under load on SSD
    Reason: malnutrition (relevant for Inspiron 15 7000 with a weak power supply).
    Solution: disable Turbo Boost in BIOS or use an original charger with a power of at least 65 W.
  5. Noises or vibrations after installing SSD
    Reason: loose carrier (for SATA) or fixing screw (for NVMe).
    Solution: Disassemble the laptop and check the fastening. There should be no vibrations in NVMe drives - this is a sign of mechanical damage.

⚠️ Specific problem for Inspiron 14 Plus 7420: When using SSD Samsung 980 Pro or WD Black SN850 an error may occur "Inaccessible Boot Device" after sleep. Solution: Disable Fast Startup in Windows (Control Panel → Power Options → What the Power Buttons Do → Change Unavailable Settings → Uncheck "Enable Fast Startup").

FAQ: answers to popular questions

Can I put two SSDs in a Dell Inspiron?

Yes, but only on certain models. For example, Inspiron 15 7501 And Inspiron 16 Plus 7620 have two slots: one for NVMe, the second - under SATA M.2 or 2.5" SATA. Check the specifications for your model on the Dell website. Please note: when using two drives, the battery will drain 15-20% faster.

Which SSD is better for gaming: NVMe or SATA?

For modern games (eg Starfield or Alan Wake 2) difference between NVMe PCIe 3.0 And SATA minimal - the main influence is exerted by the cache size and the controller. However, for games with DirectStorage (for example, Forspoken) better to choose NVMe PCIe 4.0 (For example, WD Black SN850X), as it reduces texture loading time by 20–30%.

Do I need to format the SSD before installation?

No, if you clone a system or install Windows from scratch, the program will format the disk itself. Manual formatting is only required if you plan to use the SSD as an additional storage device for data (for example, to store files). In this case, select the file system NTFS (for Windows) or exFAT (for macOS compatibility).

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

NVMe drives (especially models with a controller Phison E18) can reach temperatures up to 70°C under intense use. B Dell Inspiron this is exacerbated by the compact body. Solutions:

  • Install a 0.5mm thick thermal pad between the SSD and the bottom cover.
  • Disable Windows background indexing (Options → Search → Advanced Search Options → Indexing).
  • Use the program SSD Z for temperature monitoring. If it exceeds 75°C, replace the thermal paste on the controller chip.

Is it possible to return the old HDD if you don’t like the SSD?

Yes, but keep two things in mind:

  1. If you cloned the system to an SSD and then return the HDD, Windows may not boot due to a boot record conflict. Solution: restore the bootloader via the installation flash drive (bootrec /fixmbr on the command line).
  2. Some models Inspiron (For example, 15 5593) when replacing the disk, the seal on the screw securing the slide breaks. This does not affect the warranty, but may cause service issues.

💡

For Dell Inspiron laptops with 11th and 12th generation Intel processors (Tiger Lake, Alder Lake), the best choice is an SSD with a controller Phison E18 or Samsung Elpis. They are best compatible with chipsets HM570 And HM670, which are used in these models.
