is a versatile business laptop that supports internal M.2 SSD expansion, though its compatibility is strictly defined by specific hardware limitations. Unlike modern laptops that utilize NVMe technology, the relies on the older SATA interface for its M.2 slot. Core Compatibility Specifications To successfully upgrade your ProBook 450 G2

with an M.2 SSD, the drive must meet the following criteria: hp probook 450 g2 m2 ssd compatibility

Interface: M.2 SATA III (6Gb/s). The motherboard does not support NVMe/PCIe drives; while an NVMe drive might physically fit the slot, it will not be detected by the system.

Form Factor: 2242. This means the drive must be 22mm wide and 42mm long. Common 2280 (80mm) drives are too long for this specific slot. HP ProBook 450 G2 Go to product viewer dialog for this item

Official Capacity Support: HP documentation originally specified support for up to 120 GB. However, users have successfully tested drives up to 240 GB or larger, as BIOS limitations on capacity are rarely as strict as the initial sales documentation suggests. Installation and Dual-Drive Support

The M.2 slot is located internally, typically near the Wi-Fi card. A key advantage of this model is its ability to support a dual-storage configuration. You can install an M.2 SATA SSD to serve as a fast boot drive for your operating system while keeping the primary 2.5-inch bay for a high-capacity HDD or a secondary SATA SSD.

For the best results, look for reliable SATA-based M.2 2242 modules from reputable brands. HP Probook 450 g2 m2 - Tom's Hardware Forum

Part 3: The Better Upgrade Path – 2.5-inch SATA SSD

Here is the pragmatic conclusion of every experienced HP ProBook 450 G2 owner: Ignore the M.2 slot entirely. Upgrade the primary 2.5-inch drive bay.

Boot and BIOS notes

Ensure BIOS is up to date for best drive support and performance.
In BIOS, check SATA mode (AHCI recommended). NVMe options will not appear on this model.

Option B: mSATA SSD (If slot present)

Some 450 G2 units have an mSATA slot (usually for Intel Smart Response caching).
Check physically: near Wi-Fi card or under palm rest.
If present, you can install a small mSATA SSD (e.g., 128–256 GB) as boot drive + keep 2.5" HDD for storage.
Warning: mSATA is NOT M.2. Physically different shape and connector.

Option A: The Direct M.2 Replacement (Difficult to Find)

If you want to use the internal M.2 slot, look for these models:

Transcend MTS420S (M.2 2242 SATA): This is arguably the best readily available drive for this specific laptop. It is fast (SATA III limits apply) and reliable.
Kingston SM2280S3: Another reliable option, though ensure you are buying the SATA version.

Note: You are limited to 256GB or 512GB capacities typically for the 2242 form factor.

Option A: 2.5-inch SATA SSD (Recommended)

Standard 7mm or 9.5mm thick SATA III SSD.
Replaces the existing hard drive.
Examples: Samsung 870 EVO, Crucial MX500, WD Blue 3D NAND.
Performance: Up to ~550 MB/s read/write – huge improvement over HDD.
