Samsung 9100 PRO 4TB PCIe 5.0 NVMe SSD

The Samsung 9100 PRO 4TB is an M.2 2280 internal solid-state drive that uses a PCI-Express 5.0 x4 interface and the NVMe 2.0 protocol. It is built with Samsung V-NAND TLC (V8) memory and an in-house controller paired with a 4GB LPDDR4X cache. The drive targets consumers who need high throughput for AI computing, gaming and heavy-duty workstation workloads.

Upgrade from PCIe 4.0 drives such as the 990 PRO

Moving from a PCIe 4.0 NVMe SSD to this PCIe 5.0 model adds sequential read speeds up to 14800 MBps and sequential write speeds up to 13400 MBps. Random performance reaches 2200000 IOPS read and 2600000 IOPS write. The jump is worth it when workloads saturate the older bus, such as large dataset training, 4K or 8K video editing, or games that stream assets directly from storage.

Sustained load behaviour and thermal control

Intelligent TurboWrite 2.0 provides a 964GB write buffer that absorbs bursts before folding back to native TLC speeds. The controller manages power with a 5.7mW device sleep state and dynamic thermal throttling to maintain performance without a heatsink. Encryption support includes Class 0 AES 256, TCG Opal 2.0 and IEEE 1667 eDrive. Rated endurance is 2400 TBW.

Questions about this item

Does the M.2 2280 form factor fit my motherboard slot?

The drive uses the standard M.2 2280 form factor, so it fits any motherboard with an M.2 key‑M slot that supports PCIe 5.0 x4.

What is the common mistake when installing the 9100 PRO without a heatsink?

Many builders forget to enable the motherboard’s active cooling for the M.2 slot; without airflow the controller can throttle under sustained PCIe 5.0 loads.

When should I expect the 4TB drive to reach its 2400 TBW endurance limit?

At 2400 TBW, the drive is rated for 2.4 petabytes of host writes; typical heavy workloads reach that point after several years of daily multi‑terabyte transfers.
