Specifications side by side

How to choose the right one

1. Check interface compatibility

   You must match the drive interface to your laptop’s slot. The Samsung 870 QVO uses SATA III, which fits older or standard 2.5-inch bays. If your laptop has an M.2 slot, you need an NVMe drive. The PM991a supports PCIe 3.0, while the BM9C1 requires PCIe 4.0. Using the wrong interface means the drive will not work. Verify your motherboard or laptop manual to see which protocol is supported before purchasing.

2. Measure M.2 length

   M.2 drives come in different physical lengths. The PM991a and BM9C1 both use the 2230 form factor, which is shorter than standard 2280 sticks. This size is ideal for thin laptops, mini PCs, or handhelds like the Steam Deck. Standard desktop motherboards usually require longer 2280 drives. Measure your available slot space carefully. If your slot is too short for a 2280 drive, you must choose a 2230 model like the ones listed here to ensure a proper fit.

3. Select proper form factor

   Your laptop determines the physical shape of the drive you can install. Most traditional laptops use a 2.5-inch bay for SATA drives like the 870 QVO or 870 EVO. These are thicker and wider but offer high capacity. Modern ultrabooks often lack this bay and use M.2 slots instead. The 870 QVO is 2.76 inches wide and 0.27 inches thick. Ensure your device has the correct physical space for the drive you select to avoid installation issues.

4. Verify capacity needs

   Storage capacity varies significantly across these models. The Samsung 870 QVO offers 8TB, which is massive for storing large files, videos, or extensive game libraries. The 870 EVO provides 500GB, suitable for basic operating system and application storage. The M.2 options offer 1TB and 512GB respectively. Consider your data usage habits. If you store many large files, prioritize higher capacity. If you only need space for the OS and core apps, smaller drives may suffice and save space.

5. Match device type

   Different drives suit different devices. The 870 QVO and 870 EVO are designed for laptops with standard 2.5-inch drive bays. The PM991a is specifically noted for Steam Deck and Surface device upgrades. The BM9C1 targets thin laptops and mini PCs with 2230 slots. Do not assume all NVMe drives fit all laptops. Check your specific hardware model against the compatibility notes. Choosing a drive for the wrong device type will result in a product that cannot be installed or used.
