Samsung 9100 PRO internal SSD 4 TB MZ-VAP4T0BW, M.2 2280 PCIe 5.0, 14800 MB/s

The 9100 PRO uses four PCIe 5.0 lanes and the NVMe 2.0 protocol. Reads of up to 14,800 MB/s and writes of up to 13,400 MB/s mean a game folder or video project of several tens of gigabytes moves in seconds. According to Samsung, sequential performance is roughly twice that of the previous 990 PRO. Full speed needs an M.2 slot with PCIe 5.0 support; in a PCIe 4.0 slot the drive still works, but the slot sets the limit.

In everyday use random performance matters more than sequential figures: booting, opening programs and game loading screens are made of thousands of small files. The 4 TB model reaches up to 2,200,000 IOPS for 4 KB random reads and 2,600,000 IOPS for random writes. The memory chips are Samsung V-NAND TLC. High random speed pays off most when several apps run at once, for example a game, a stream and a browser.

This version comes without a heatsink: it is 2.38 mm thick and weighs 9 g, so it fits tight spaces such as a laptop or the area under a motherboard M.2 cover. According to Samsung, the 5 nm controller improves power efficiency by up to 49% compared with the 990 PRO. Average power draw is 9 W when reading and 8.2 W when writing, and the operating range is 0–70 °C.

The form factor is M.2 2280, or 22 × 80 mm, used on most current motherboards and in many laptops. Samsung lists PCs and game consoles as intended uses. In a desktop, install the drive under the motherboard M.2 cover if there is one, as cooling helps hold speed during long copies. In a laptop, make sure the M.2 slot supports NVMe PCIe drives.

The drive supports hardware 256-bit AES encryption, TRIM, S.M.A.R.T. monitoring and the DevSlp power-saving state. Samsung quotes a mean time between failures (MTBF) of 1,500,000 hours and operating shock resistance of 1500 G. The Samsung Magician software helps migrate data from an old drive, monitor drive health and install firmware updates.

Video editors and 3D artists whose projects and cache files take hundreds of gigabytes and need to open instantly; developers and data analysts working with large datasets or AI models; and gamers who want the whole library on one fast drive. With 4 TB the system, programs and work all fit on one SSD without a separate slow data drive.
