Replacing the DVD drive with a second hard drive or SSD via a special adapter (often called a "box" or "sled") is one of the most popular upgrades for laptops. This method allows you to increase storage capacity without losing portability, especially important for models with one drive slot. But before buying an adapter, it is important to understand the nuances: not all laptops support such a modification, and the wrong choice of box can lead to problems with cooling or compatibility.
In this article we will look in detail at how to choose adapter for HDD instead of DVD drive, what technical characteristics to consider, and we will provide step-by-step installation instructions. You will also find out what Lenovo, HP, Dell and other brands are best suited to such an upgrade, and where difficulties may arise. If you are planning to install a second one SSD for the system or HDD for data storage - here you will find answers to all questions.
What is an adapter for HDD instead of DVD drive and how does it work?
An adapter (or “box”) for installing a hard drive instead of a DVD drive is a plastic or metal case with a connector SATA, which is inserted into the optical drive slot of the laptop. It simulates the presence of a DVD-rom, but instead of a disc tray, it contains 2.5-inch HDD or SSD. The connection is made through the standard laptop interface, so it does not require soldering or modification of the motherboard.
The operating principle is simple:
- 🔌 The adapter is connected to the connector
SATA, which was previously used by the DVD drive. - 💽 A drive is installed inside the box (usually 7 or 9.5 mm high).
- 🖥️ The system recognizes the new disk as additional storage (or boot device, if configured
BIOS).
It is important to understand that such an adapter does not increase operating speed - it depends on the interface SATA (usually SATA II or SATA III) and drive type. For example, in laptops with SATA II (up to 3 Gbit/s), even an SSD will work slower than in SATA III (6 Gbit/s). Also, some adapters require connecting additional power via USB (rare, but found in older models).

Which laptops support replacing a DVD drive with an HDD?
Not all laptops allow you to replace the DVD drive with a second drive. Main compatibility factors:
- Availability of a removable DVD drive - in ultrabooks (for example, MacBook Air or Dell XPS 13) there is no optical drive initially.
- Mounting type — the adapter must be suitable in size and method of fixation (for example, Lenovo ThinkPad use standard "sleds", and HP Pavilion - individual latches).
- BIOS support - some laptops (especially Sony VAIO or Acer old series) may block booting from the device in the DVD slot.
Below is a compatibility table of popular brands and series:
| Brand and series | Adapter support | Notes |
|---|---|---|
| Lenovo ThinkPad (T, X, W series) | ✅ Yes | Standard "sled", often requires an adapter with a metal housing. |
| HP EliteBook, ProBook | ✅ Yes | Use individual mounts, check the adapter model. |
| Dell Latitude, Inspiron (until 2018) | ✅ Yes | In newer models, the DVD drive is often integrated into the case. |
| Asus ROG, ZenBook | ⚠️ Partially | Installation is possible on gaming laptops, but not on ultrabooks. |
| Apple MacBook Pro (until 2012) | ✅ Yes | Requires an adapter that supports OptiBay and setting Boot Camp. |
⚠️ Attention: In laptops withM.2 SSDas the main drive (for example, Lenovo Yoga or HP Spectre) Replacing a DVD drive with an HDD may not provide a performance increase. In such cases, it is better to consider the option with an externalUSB 3.0drive.
How to choose an adapter for HDD instead of a DVD drive: key parameters
When choosing an adapter, pay attention to the following characteristics:
- 📏 Thickness - most adapters support drives that are tall
7 mmor9.5 mm. Check the thickness of your HDD/SSD. - 🔌 Interface - must be
SATA IIorSATA III(depending on the laptop motherboard). - 🔧 Mounting type — some adapters come with universal “sleds”, others require precise adjustment to the laptop model.
- 💨 Ventilation — metal adapters dissipate heat better, which is important for HDDs.
Popular adapter models:
- 🛒 ORICO 2139S3 - universal, supports
SATA III, metal case. - 🛒 Sabrent EC-DFLT - for laptops Dell And HP, with 9.5 mm mount.
- 🛒 Nifty Drive - specialized for MacBook Pro (until 2012).
- 🛒 KingSpec - budget option with a plastic case.
Also check if the adapter supports hot swap (hot-swap) - this will allow you to remove the disk without turning off the laptop. However, in most cases this will require configuration BIOS (shutdown AHCI not recommended).
Before purchasing an adapter, measure the thickness of your current DVD drive - some laptops (eg. Sony VAIO) use non-standard sizes (12.7 mm).
Step-by-step instructions: how to install a HDD instead of a DVD drive
The adapter installation process consists of several stages: preparing the laptop, physically replacing the drive, and setting up the system. Let's look at each step in detail.
1. Preparing a laptop and tools
You will need:
- ⚒️ Screwdriver (usually
Phillips #0orT5). - 🔧 Plastic spatula for disassembling the case (optional).
- 💾 New HDD/SSD and adapter.
- 🖥️ Bootable USB flash drive with
Windows/Linux(if you plan to install the OS on a new disk).
Unplug the laptop and remove the battery (if removable)|
Back up your data|
Check adapter compatibility with your laptop model|
Prepare your work area (preferably an antistatic mat) -->
2. Removing the DVD drive
Algorithm of actions:
- Turn the laptop over and locate the DVD drive mount (usually secured with 1-2 screws).
- Unscrew the screws and gently pull the drive towards you - it should come out of the connector.
- If the drive cannot be removed, check for hidden latches (for example, in Lenovo ThinkPad you need to press the latch on the right).
Some laptops (eg. HP EliteBook 840) The DVD drive is attached to the case with an additional frame - this also needs to be removed.
3. Installing the adapter from the HDD
Follow the order:
- Insert the HDD/SSD into the adapter and secure with screws (usually 4 pieces).
- Connect the adapter to the connector
SATAin a laptop (similar to a DVD drive). - Secure the adapter with screws and replace the laptop cover.
⚠️ Attention: If after installation the laptop does not turn on or does not recognize the disk, check:
- Contact tightness
SATA(sometimes a slight rocking of the adapter helps).- Settings
BIOS- the disk can be disconnected in the partitionBootorStorage.
4. BIOS and system setup
After physical installation:
- Turn on your laptop and go to
BIOS(usually the keyF2,DelorEsc). - Check that the new drive appears in the partition
StorageorBoot. - If the disk is not visible, update
BIOSor reset to factory settings. - B
WindowsopenDisk management(diskmgmt.msc) and initialize the new drive.
To install the system on a new disk:
- 🔄 Use a bootable USB flash drive and select the drive as the destination.
- ⚠️ If you install
WindowsonSSDin the DVD slot, disable Secure Boot inBIOS(on some laptops HP or Dell).
If the laptop does not boot after installing the adapter, try temporarily disabling the main drive in the BIOS and checking the functionality of the new drive separately.
Common problems and their solutions
Even with proper installation, difficulties may arise. Let's look at typical cases and ways to eliminate them.
1. The laptop does not see the new disk
Possible causes and solutions:
- 🔌 Poor contact — check whether the adapter is tightly inserted into the connector
SATA. Try pressing it lightly with your hand when turning it on. - 🔧 Incompatible adapter - some laptops (for example, Acer Aspire) require adapters with additional power supply
USB. - 🖥️ Lack of drivers - in
Windows 7driver installation may be requiredAHCImanually. - 🛠️ Bad sectors on the disk — check the health of the HDD/SSD with the utility
CrystalDiskInfo.
2. The laptop overheats after installing the HDD
Additional storage may increase temperatures, especially if:
- 🔥 The adapter is plastic and does not dissipate heat.
- 💨 The ventilation holes of the laptop are blocked.
- 🖥️ HDD (unlike SSD) heats up on its own.
Solutions:
- 🛠️ Replace the plastic adapter with a metal one (for example, ORICO 2139S3).
- 💨 Use a laptop cooling pad.
- 🔄 Transfer frequently used files to
SSD, andHDDuse for archive.
3. Slow operation of the disc in the DVD slot
If read/write speed is lower than expected:
- 🔌 Check the version
SATAon a laptop (viaHWiNFO). If thisSATA II, thenSSDwill operate at speeds up to 300 MB/s. - 🔧 Update the firmware
BIOS- in older versions there may be a limitation on the speed of devices in the DVD slot. - 🛠️ Disable compatibility mode
IDEinBIOS(must beAHCI).
How to check disk speed?
Download the utility CrystalDiskMark and run the sequential read/write test. For SATA III SSD normal values are 500+ MB/s, for HDD — 100–150 MB/s. If the speed is lower, the problem is in the interface or settings.
Comparison of HDD and SSD for installation instead of a DVD drive
Choice between HDD And SSD depends on your tasks. Below is a comparison of key parameters:
| Parameter | HDD (hard disk) | SSD (solid state) |
|---|---|---|
| 💰 Price for 1 TB | ~3 000 ₽ | ~8 000–12 000 ₽ |
| ⚡ Read/write speed | 80–160 MB/s | 500–3500 MB/s (depending on SATA/NVMe) |
| 🔋 Energy consumption | 5–10 W | 2–5 W |
| 🛡️ Shock resistant | Low (risk of damage if dropped) | High (no moving parts) |
| 🔊 Noise | Can be heard during operation | Silent |
Recommendations for selection:
- 🎮 For gaming and working with large files —
SSD(fast loading of levels, no freezes). - 📁 For storing films, photos, archives —
HDD(cheaper per gigabyte). - 💼 For office work —
SSD(fast program launch, low power consumption).
If your budget allows, the best option is SSD into the main slot (for the system) and HDD instead of a DVD drive (for data). For example, in Lenovo ThinkPad T480 This solution gives both speed and capacity.
Alternatives to an adapter for HDD instead of a DVD drive
If replacing the DVD drive is not possible or convenient, consider alternative storage expansion options:
- 🔌 External HDD/SSD via USB 3.0/3.1 — speed up to 500 MB/s (suitable for backups).
- 🔄 Replacing the main HDD with a larger capacity SSD - for example,
Samsung 870 EVO 2 TB. - 💽 Using the M.2 slot - if the laptop has a free slot (for example, in Dell XPS 15).
- ☁️ Cloud storage — Google Drive, Yandex Disk or Dropbox for rarely used files.
Comparison of alternatives with adapter:
| Solution | Pros | Cons |
|---|---|---|
| Adapter instead of DVD | Cheap, does not take up ports, internal connection | Speed limit (SATA II), not all laptops support |
| External HDD via USB | Versatile, easy to connect to another PC | Port occupies, depends on speed USB |
| Replacing the Primary Drive | Maximum speed, reliability | Requires system reinstallation, data loss due to careless replacement |
| Cloud storage | Access from any device, no risk of data loss | Limited volume, Internet dependence |
If you need maximum storage capacity without loss of mobility, an adapter instead of a DVD drive remains one of the best solutions. However, for modern ultrabooks (for example, MacBook Pro M1 or Dell XPS 13) alternatives like external storage or clouds would be more appropriate.
FAQ: answers to frequently asked questions
❓ Is it possible to install an SSD instead of a DVD drive in a laptop with SATA II?
Yes, but SSD speed will be limited by bandwidth SATA II (up to 300 MB/s). For comparison, SATA III SSD in this mode it will lose up to 50% of performance. If your laptop only supports SATA II, it makes sense to consider the installation HDD for data storage, and leave the system on the main disk.
❓ Do I need to format the new disk after installation?
Yes, a new HDD or SSD requires initialization and formatting. B Windows this is done through Disk management (diskmgmt.msc): find a new disk (marked as "Unallocated"), create a partition on it and format it as NTFS (or exFAT for compatibility with macOS).
❓ Will the laptop get hotter after installing an HDD instead of a DVD?
Possibly, but not critical. An HDD generates more heat than an SSD, but less than a DVD drive when burning a disc. If the laptop is already prone to overheating (for example, HP Pavilion Gaming), install the metal adapter and use a cooling pad. You can also transfer frequently used programs to the main disk, and leave the HDD for archives.
❓ Is it possible to install two SSDs: one instead of an HDD, the other instead of a DVD?
Technically yes, but there are some nuances:
- 🔧 Both drives will work at speed
SATA-interface (if the laptop does not haveM.2). - 🖥️ In some laptops (for example, Lenovo IdeaPad) DVD slot is connected via
USB 2.0internally - this will limit the speed to 40 MB/s. - ⚡ Energy consumption will increase, which will reduce battery life.
For maximum performance it is better to install NVMe SSD into slot M.2 (if there is one), and put it instead of DVD HDD for data.
❓ How to transfer the system to an SSD installed instead of a DVD drive?
The most reliable way is to clone the disk using Macrium Reflect or Clonezilla:
- Connect the new SSD via an adapter.
- Create a bootable USB flash drive with the cloning program.
- Clone the main drive to the SSD (selecting the "Sector-by-Sector Copy" option to
SSD). - B
BIOSchange the boot priority by selecting a new drive.
Alternative - clean installation Windows to an SSD and then restoring data from a backup copy.
