Replacing an outdated DVD drive with an additional SSD is one of the most effective laptop upgrades. This allows you to increase your storage capacity without losing speed, while maintaining the original hard drive. However, not everyone knows that such an upgrade requires a special adapter - SSD carriers (or caddy). Choosing the wrong model can lead to mounting problems, overheating, or even damaged connectors.

In this article we will look at all selection criteria: from compatibility with your laptop model to the nuances of SATA III connection. You will find out what brands trustworthy, how to avoid common installation mistakes and what to do if the adapter is not recognized by the system. And for those who doubt the need for an upgrade, we have prepared a comparative table of SSD and HDD speeds in real tasks.

Before you make a purchase, ask yourself three key questions:

  • 🔍 What thickness is your DVD drive (9.5 mm or 12.7 mm)?
  • 💻 Does it support does your laptop boot from the second drive?
  • 🔌 Is there Does the adapter have an additional power connector (if required)?
📊 Why do you want to replace your DVD drive with an SSD?
  • Increase storage capacity
  • Speed up the system
  • Install a second SSD for games/work
  • DVD drive is broken
  • Another option

1. Why an SSD tray is a better choice over a DVD drive

Sled (or caddy) is a metal or plastic adapter that allows you to install 2.5" SSD into the compartment intended for a DVD drive. The main advantages of this solution:

  • 🚀 Speed increase: SSD is 5-10 times faster than HDD (see comparison table below).
  • 📦 Extra space: You can leave the old HDD for files, and install the system on the SSD.
  • 🔧 Easy to install: Requires no soldering or modification of the case.
  • 💰 Savings: Cheaper than buying a laptop with two M.2 slots.

However, there are also pitfalls. For example, in some laptops no AHCI support for the second drive, which limits the speed to SATA II (3 Gbps). It is also important to consider adapter thickness: If you choose a 12.7mm model for a 9.5mm bay, the slides simply won't fit into place.

What happens if you install an SSD without a carrier?

Without an adapter, the drive will dangle in the bay, which will lead to vibrations, overheating and possible damage to the connectors. In addition, the laptop may not recognize the disk due to the incorrect position of the contacts.

Parameter HDD (in DVD bay) SSD in a sled
Reading speed 80–120 MB/s 500–550 MB/s (SATA III)
Write speed 60–100 MB/s 450–520 MB/s
Windows boot time 40–60 sec 10–15 sec
Noise level Can be heard during operation Silent
Energy consumption 6–7 W 2–3 W

2. How to determine if the sled is compatible with your laptop

The first thing to do is find out the thickness of your DVD drive. To do this:

  1. Turn off the laptop and remove the drive (usually it is secured with 1-2 screws on the bottom cover).
  2. Look at the markings or measure with a caliper. Standard sizes:
    • 9.5 mm - most ultrabooks and modern laptops.
    • 12.7 mm — old models (before 2015) and gaming laptops.
  • Check connection interface: must be SATA (not IDE/PATA, as in very old models).

    • Second - check second disk support in BIOS. Some laptops (eg. Lenovo ThinkPad T440 or Dell Latitude E6430) require the mode to be turned on AHCI for the second SATA port. If there is no option in BIOS SATA Mode for the second drive, SSD speed may be limited 3 Gbit/s instead of 6 Gbit/s.

    💡

    If you are not sure about the thickness of the drive, look for the laptop model on the website of the sled manufacturer (for example, Nifty Drive or ORICO) - there are often compatibility tables there.

    3. Top 5 SSD carriers: comparison of models and prices

    4. Step-by-step instructions for installing an SSD into a sled

    The installation process takes 15–20 minutes. You will need:

    • 🔧 Phillips screwdriver (usually PH0 or PH1).
    • 📏 Plastic spatula (for carefully removing the drive).
    • 🖥️ SSD form factor 2.5" (7 mm or 9.5 mm in height).

    Step 1: Removing the DVD Drive:

    1. Turn off the laptop and disconnect the battery (if it is removable).
    2. Turn the laptop over and locate the DVD drive cover (usually it is secured with 1-2 screws).
    3. Carefully pull the drive towards you, holding it by the special latch.

    Step 2: Install the SSD into the carrier:

    1. Screw the SSD to the adapter with the screws provided (do not overtighten!).
    2. Connect the SSD to the connector SATA on a sled.
    3. If your model has an additional power connector (for example, for Dell Inspiron), connect it.

    Step 3: Reassembly:

    1. Insert the SSD carrier into the bay instead of the DVD drive.
    2. Tighten the screws and turn on the laptop.
    3. Check if the disc is recognized in BIOS (key F2/Del when loading).

    1) Connector tightness (sometimes it helps to reconnect the drive).

    2) BIOS settings (AHCI mode for the second SATA port must be enabled).

    3) Compatibility of the sled with your laptop model (some adapters do not work with Lenovo Yoga or HP Specter).-->

    5. Common mistakes and how to avoid them

    Even experienced users sometimes encounter problems when installing an SSD into a sled. Here top 5 mistakes and their solutions:

    ⚠️ Attention: If after installation the laptop does not turn on or the SSD heats up to 70°C+, immediately turn off the power! This may indicate a short circuit due to improper connection.
    • 🔌 Disk is not detected in BIOS:
      • Check if it is enabled SATA Port 1/2 in BIOS settings.
      • Update the BIOS (on some ASUS And Acer latest version required).
    • 🌡️ SSD overheats:
      • Use a sled with a metal body (plastic dissipates heat worse).
      • Add a thermal pad between the SSD and the adapter.
    • 🐢 Speed is lower than expected:
      • Check that the drive is connected to SATA III (6 Gbit/s), and not to SATA II.
      • Disable mode IDE in BIOS.

    Another common problem is screws don't fit to SSD mounts. In this case, you can use racks from an old HDD or buy a universal set of screws (M3x3mm).

    6. Alternatives to skids: when they don't fit

    In some cases, skids are not the best option. Let's look at the alternatives:

    • 💾 External SSD box:
      • Suitable if you don't want to disassemble your laptop.
      • Disadvantage: it takes up a USB port and requires separate power.
    • 🔄 Replacing HDD with SSD + external HDD:
      • If your laptop only has one drive bay, you can move the HDD to an external case.
      • Plus: system speed will increase due to the SSD.
    • 🖥️ M.2 SSD instead of a sled:
      • If your laptop has a free slot M.2, it is better to install an NVMe drive there.
      • The speed will be 3-5 times faster than SATA SSD.

    The skid is justified if:

    • In the laptop no M.2 slot.
    • Do you want save both disks (HDD + SSD).
    • Yours DVD drive is broken and is not used.

    7. How to transfer the system to a new SSD without reinstalling

    After installing the sled, you need to migrate the system to the SSD. The most reliable ways:

    1. Disk cloning with the help Macrium Reflect or Clonezilla:
      • Create a bootable USB flash drive with the program.
      • Connect the SSD via a carrier or USB adapter.
      • Select the source disk (HDD) and target disk (SSD), start cloning.
    2. Clean Windows installation:
      • Download Media Creation Tool from the Microsoft website.
      • Create an installation flash drive and install the system on the SSD.
      • Manually transfer data from the old drive.

    Important note: if you clone a disk, SSD size must be at leastthan the occupied space on the HDD. For example, if the HDD is occupied by 300 GB, the SSD should be at least 320–350 GB.

    1) Disconnect the old HDD during the first boot from the SSD (to avoid bootloader conflicts).

    2) Update chipset and SATA controller drivers for maximum speed.-->

    FAQ: Frequently asked questions about SSD carriers

    ❓ Is it possible to install an M.2 SSD in the sled?

    No, the sled is only for 2.5-inch SSD with interface SATA. For M.2 other adapters are needed (for example, M.2 to SATA, but they are slower due to protocol limitations).

    ❓ Will the sled work with a 2 TB SSD?

    Yes, but only if the adapter supports LBA addressing for large disks. Most modern sleds (eg. Sabrent EC-DFLT or Nifty Drive) are compatible with SSDs up to 2 TB. Problems may only occur on very old laptops (pre-2012).

    ❓ Do I need to configure the BIOS after installing an SSD?

    In most cases no, but it is recommended:

    • Check what's in Boot Priority the new SSD comes first.
    • Make sure that the second SATA port is enabled AHCI (not IDE).
    • Disable Secure Boot, if the system does not boot.

    ❓ Can the slides be used to install an HDD instead of a DVD?

    Technically yes, but this inappropriate:

    • The HDD in the sled will heat up more due to poor ventilation.
    • Read/write speed will not increase (unlike SSD).
    • HDD vibrations can damage the adapter connectors.

    ❓ Where to buy SSD slides with a guarantee?

    Best options:

    • 🛒 Official stores: Nifty Drive (niftydrive.com), ORICO (orico.com.cn).
    • 🌍 AliExpress: cheaper, but delivery takes 2–4 weeks. Look for sellers with a 98%+ rating.
    • 🏬 Local stores: “Citylink”, “Regard”, “DNS” (limited assortment, but fast delivery).

    The average price of quality sleds is 1 000–2 500 ₽. Avoid models cheaper than 800 ₽: they often have poor contacts.
