Replacing a DVD drive with a second hard drive or SSD via slides for HDD 2.5 is one of the most popular laptop upgrades of the last decade. With the development of cloud storage and streaming services, optical disks have lost their relevance, and the free slot can be used for good: adding space for files, speeding up the system, or organizing backups. However, not all adapters are equally compatible with laptops from different brands, and incorrect installation can lead to overheating, data loss, or even damaged connectors.

In this article we will look at how choose the right skid for a specific laptop model, what technical nuances to consider when purchasing (from case height to interface type), and we will provide step-by-step installation instructions with photos and tips for setting up the BIOS. You will also learn what mistakes users most often make during installation and how to avoid them so that the new drive works stably and for a long time.

Why change your DVD drive to HDD/SSD: 5 good reasons

Before spending money on an adapter, it's worth assessing whether you really need this modification. Here are the key benefits that users receive after the replacement:

  • 🔥 Increased productivity: Installing an SSD in a sled instead of an HDD allows you to use it as a disk for the system or cache, speeding up the loading of the OS and programs by 3-5 times.
  • 💾 Additional storage: A second hard drive (up to 5 TB) solves the problem of running out of space for games, videos or projects without external drives.
  • 🔄 Backup: The second disk can be configured to automatically duplicate important data (via RAID 1 or programs like Macrium Reflect).
  • 🌡️ Improved cooling: Modern SSDs generate less heat than DVD drives, which reduces the load on the laptop's cooling system.
  • 💰 Savings on external devices: Instead of buying an external HDD or USB hub, you get a built-in drive without unnecessary wires.

However, there are also nuances. For example, in some ultrabooks (MacBook Air, Dell XPS 13) There is no DVD drive out of the box, but gaming laptops (ASUS ROG, MSI GT) there may not be enough power for two drives at the same time. It's also worth remembering that Some models of the slide block access to the DVD tray, making it non-removable without disassembling the laptop.

📊 Have you already changed your DVD drive to HDD/SSD?
  • Yes, I installed it myself
  • Yes, at the service center
  • I plan to, but haven't tried it
  • No, I don't see the point

Types of sleds for HDD 2.5: how not to make a mistake with the choice

All adapters for replacing DVD drives are divided into three main types, differing in design and compatibility. The choice depends on the laptop model, drive type and your tasks:

Slide type Features Pros Cons Example models
Universal (9.5 mm) Fits most laptops with a standard height DVD drive Low price, wide compatibility May not be suitable for thin laptops (12.7mm) ORICO 2599US3, Sabrent EC-DFLT
Ultra-thin (12.7 mm) For laptops with slim-DVD (eg Lenovo ThinkPad T/X, HP EliteBook) Compact, often with a metal body More expensive than generic ones, less choice Kingston SNV2S/250G, Transcend TS256GMTS430S
Supports M.2 (NVMe/SATA) Allows you to install an M.2 SSD instead of a 2.5" HDD High speed (up to 3500 MB/s for NVMe) Requires BIOS compatibility, may overheat StarTech M.2 NGFF, Wavlink WL-UAM2

The key parameter when choosing is case height. Most DVD drives have a standard 9.5 mm, but in thin laptops (for example, Sony VAIO or Acer Swift) drives are used 12.7 mm. To be on the safe side, measure the thickness of your DVD drive with a caliper or look at the model specifications on the manufacturer's website.

⚠️ Attention: Some skids (for example, for Dell Latitude) have unique power connectors. If the adapter does not fit the connector, do not try to connect it through adapters - this may burn the SATA controller!

Step-by-step instructions: how to install a slide for HDD 2.5

Installing the adapter does not require a soldering iron or special skills, but will require care. Follow the instructions to avoid errors:

Unplug the laptop and remove the battery (if removable)

Prepare a Phillips screwdriver and a plastic spatula

Download a backup copy of your data from your main drive

Check the compatibility of the sled with your laptop model -->

Step 1: Removing the DVD Drive

On most laptops, the drive is secured with a single screw on the bottom cover (usually marked with a DVD icon). Unscrew it, then gently pull the drive by the front panel - it should come out of the connector. On some models (HP Pavilion, Lenovo IdeaPad) you will need to remove the entire bottom cover.

Step 2: Transfer the front panel

Remove the front cover from the DVD drive and attach it to the slide. It is usually secured with latches or screws. If the panel does not fit, use an adapter with a universal face (for example, ORICO 2599US3).

Step 3. Installing the HDD/SSD into the carrier

Secure the drive to the adapter with screws (usually included). Pay attention to the position of the SATA connector - it should match the connector on the sled. For SSDs, it is recommended to use foam pads to avoid vibrations.

Step 4. Connection and testing

Insert the disc tray into the slot instead of the DVD drive until it clicks into place. Turn on the laptop and check if the new drive is detected in the BIOS (Boot Menu or section Storage). If the disk is not visible, try:

  • 🔌 Reconnect the sled (the connector may not be fully inserted).
  • 🔧 Update BIOS (on some laptops ASUS And Acer A version of at least 2018 is required).
  • 🛠️ Check settings AHCI/IDE in the BIOS (for SSD it is better to use AHCI).
💡

If, after installing the SSD in the tray, the laptop begins to boot more slowly, check the boot priority in the BIOS. Sometimes the system tries to boot from a new disk that does not have an OS.

Laptop compatibility: table by brand

Not all sleds fit all laptops. Below are proven adapter models for popular brands. If your model is not listed, search for the sled by the exact name of the DVD drive (for example, Panasonic UJ-8A8 or HL-DT-ST DVDRAM GU90N).

Laptop brand Recommended skids Features
Lenovo ThinkPad (T/X/W) Lenovo 43N3416 (original), ORICO 2599US3 Requires a thin adapter (12.7mm). In models with Ultrabay Hot swap supported.
Dell Latitude/Inspiron Dell 0M3K9G, Sabrent EC-DFLT B Latitude E7440 and newer may require a BIOS update to work with the SSD.
HP EliteBook/ProBook HP 699953-001, Wavlink WL-UAM2 B EliteBook 840 G3 and above the slide blocks access to mSATA-slot.
ASUS ROG/ZenBook ASUS 90NB0TY1-M00660, StarTech SAT22M25 In game models (ROG Strix) there may not be enough power for two SSDs at the same time.

For laptops Apple MacBook Pro (until 2015) suitable skids OWC Data Doubler, but they require an additional power cable. In models MacBook Air and new MacBook Pro (since 2016) There is no DVD drive, so an upgrade is only possible by replacing the main SSD.

How to find out the model of the DVD drive in a laptop?

Open Device Manager (Win + X → Device Manager).

Expand the thread DVD and CD-ROM drives.

Copy the drive name (for example, HL-DT-ST DVDRAM GU90N).

Enter the name into a search engine, adding the words "caddy" or "sled".

Top 5 mistakes when installing skids and how to avoid them

Even experienced users sometimes encounter problems after installing the adapter. Here are the most common mistakes and how to solve them:

  1. Disk is not detected in BIOS

    Cause: The carrier is incompatible with the SATA controller or the BIOS settings are incorrect.
    Solution: Check if the mode is turned on AHCI in BIOS. If that doesn't help, try another adapter (for example, with a chip JMicron JMB575).

  2. Laptop won't turn on after installation

    Cause: Short circuit due to incorrect power connection.
    Solution: Disconnect the carrier and check if the pins on the SATA connector are bent. In some laptops (Sony VAIO) additional power cable required.

  3. SSD in carrier runs slower than it should

    Reason: The adapter limits the speed to SATA II (3 Gb/s) instead of SATA III (6 Gb/s).
    Solution: Buy a sled with support SATA 6Gb/s (For example, Sabrent EC-DFLT or StarTech SAT22M25).

  4. Laptop overheating after installation

    Cause: Poor ventilation due to blocked air passages.
    Solution: Use a slot with perforations or install a thermal pad between the SSD and the case.

  5. The drive turns off during operation

    Cause: Insufficient power or poor contact in the connector.
    Solution: Check whether the mounting screws are loose. If the problem persists, try connecting the drive via a USB adapter for diagnostics.

⚠️ Attention: In laptops Lenovo Yoga And HP Spectre With flexible DVD drive cables, the slides may not fit physically - before purchasing, disassemble the laptop and check the type of connector!

Optimizing the operation of the second disk: settings and software

Once you've installed the sled, it's not enough to just copy the files to the new drive. To maximize performance and security, follow these steps:

1. BIOS/UEFI setup

  • 🔧 Set the mode AHCI for SATA (especially important for SSD).
  • 🔄 If there is an option Hot Swap for a DVD drive, turn it on - this will allow you to remove the sled without turning off the laptop.
  • 🚫 Disable Secure Boot, if you plan to install an alternative OS (for example, Linux) on the second disk.

2. Partitioning and formatting the disk

For HDD it is better to use a file system NTFS (for Windows) or ext4 (for Linux). Optimal for SSD NTFS with defragmentation turned off. Markup can be done via:

  • 🖥️ Built-in utility Disk management (Win + R → diskmgmt.msc).
  • 🛠️ Programs MiniTool Partition Wizard or GParted (for complex marking schemes).

3. Disk management programs

Problem Program Features
System cloning Macrium Reflect, Clonezilla Allows you to transfer the OS to SSD without reinstallation
SSD Health Monitoring CrystalDiskInfo, SSDLife Monitors cell wear and temperature
SSD optimization Samsung Magician (for Samsung SSD) Includes RAPID Mode and updates the firmware
💡

If you are installing an SSD in a system tray, be sure to transfer the boot loader (MBR/GPT) and reactivate Windows - cloning may reset the license!

Alternatives to Skids: When They're Not Suitable

In some cases, installing a skid is impossible or impractical. Let's look at alternative ways to expand storage:

  • 🔌 External SSD/HDD via USB 3.0/Type-C: Modern storage devices (for example, Samsung T7) reach speeds of 1000 MB/s - almost like internal SATA SSDs. Disadvantage: it takes up a port and requires power.
  • 🔄 Replacing the main HDD with a larger SSD: If the laptop has one slot, you can install SSD 2.5" 2 TB (For example, Crucial MX500) instead of the old HDD.
  • 📀 M.2 SSD in a free slot: Many laptops (ASUS Vivobook, Lenovo Legion) have an additional slot M.2 2280 for NVMe drive.
  • ☁️ Cloud storage: Suitable for backups Google Drive, Yandex Disk or Backblaze (from 5 TB for $5/month).

If your laptop does not have a slot M.2, but there is a free port mSATA (found in Dell Latitude E6430, HP EliteBook 8470p), you can use an adapter mSATA to M.2 NGFF for installing a modern NVMe drive.

⚠️ Attention: In laptops with Optane Memory (for example some HP Pavilion And Acer Swift) installing a second SSD may conflict with the caching module. In this case, disable Optane in BIOS before installation.

FAQ: Frequently asked questions about HDD 2.5 sleds

Is it possible to install an SSD and HDD into the sled at the same time?

Technically yes, but only if the laptop has two SATA slots (for example, in Lenovo ThinkPad P50 or Dell Precision). In most cases, the slide takes up the only slot of the DVD drive, so you will have to connect the second drive via USB or replace the main HDD with an SSD.

Will an SSD in a sled run at maximum speed?

The speed depends on the version of the SATA adapter. Most sleds support SATA III (6 Gb/s), but some cheap models are limited SATA II (3 Gb/s). Check the adapter specifications before purchasing. For NVMe drives (via M.2) speed can reach 3500 MB/s, but only if the sled is equipped with a chip ASM1166 or similar.

Do I need to update the BIOS before installing the sled?

Updating the BIOS is recommended for laptops older than 2015 (especially ASUS, Acer And Sony VAIO). New firmware versions often add support for modern SSDs and fix errors with detecting devices in the DVD slot. Download BIOS only from the official website of the manufacturer!

Can I use the carrier to install a second SSD under the system?

Yes, but you will need to transfer the bootloader. The most reliable way:

  1. Install the SSD into the carrier and connect it to the laptop.
  2. Clone the system from the main drive to the SSD using Macrium Reflect or Acronis True Image.
  3. In BIOS, change the boot priority to the new drive.
  4. Format the old HDD for data storage.

What should I do if the sled doesn't fit?

If the adapter is too thick or thin, you can:

  • Use foam gaskets for fixation (temporary solution).
  • Buy universal slides with adjustable height (For example, ORICO 2599US3).
  • Order 3D printing a custom adapter according to the size of your DVD drive.
