| Drive Model | Interface | Capacity | Notes | |-------------|-----------|----------|-------| | | SATA III (over M.2 B-key) | 64GB | OEM drive (rare). Works as a cache or boot drive after BIOS update F.42+. | | SanDisk Z400s (M.2 2242 B-key) | SATA III | 64GB, 128GB | Requires legacy boot mode (UEFI may struggle). Performance is capped at ~250MB/s. | | Kingston RBU-SNS8152P3 | SATA III | 32GB–128GB | Originally designed for Lenovo caching. Requires disabling secure boot. | | Toshiba (Kioxia) HG5d | SATA III | 64GB | Very old stock. Works intermittently depending on BIOS revision. |
You may have read that some users installed an NVMe SSD and that the BIOS “detected” it. For example, one user reported: “I installed a 1TB NVMe PCIe M.2 2242 SSD and the BIOS is able to detect it and enables option for m.2 boot” . However, the same user also stated that , making it unusable for everyday computing. Even if the BIOS shows the drive, the lack of a proper NVMe controller driver in the chipset means Windows cannot access the storage. Do not waste money on an NVMe drive for the ProBook 450 G2 – it will not work as a functional storage device.
Before purchasing hardware, you must understand the exact storage architecture of the HP ProBook 450 G2. Installing the wrong type of SSD will result in the drive not being recognized by the BIOS, or it physically failing to fit into the slot.

You can find a working M.2 SSD, but it will be:
Yes. The ProBook 450 G2’s chipset supports Intel SRT, which allows you to use a small SSD (typically 64–128 GB) as a cache for a larger HDD. You would need to configure the system in RAID mode in the BIOS and use Intel’s Rapid Storage Technology driver in Windows. | Drive Model | Interface | Capacity |
The features a dedicated M.2 slot for internal storage upgrades, but it has very specific physical and interface requirements. Key Compatibility Specs
A: Possibly, or he owns a rare revision (e.g., 450 G2 with a different motherboard for the Asian market). For 95% of units, it will not work. Performance is capped at ~250MB/s
This is the most common mistake upgraders make. The M.2 slot in the 450 G2 is electrically wired for , not PCIe/NVMe.
Standard drives (80mm long), which are the most common on the market today, will not fit because the mounting screw post is positioned strictly for a 42mm drive, and there is insufficient physical clearance inside the chassis. Keying Configuration
