Samsung 980 PRO 1TB PCIe 4.0 NVMe SSD (MZ-V8P1T0B/AM): specs and fit

The Samsung 980 PRO 1TB (model MZ-V8P1T0B/AM) is an internal M.2 solid state drive that uses PCIe 4.0 and the NVMe protocol. Samsung aims it at gamers and technically minded users who want quick system and application storage. This page explains the numbers on the spec sheet and what the drive needs to perform as described.

Reading the speed figures

Samsung gives these sequential figures: up to 3,500MB/s for reads, and up to 3,400MB/s for writes on the 500GB model. For random performance it lists up to 690K IOPS for reads on the 500GB and 1TB versions, and 620K IOPS for writes on the 250GB and 500GB versions.

Sequential speed describes moving large, continuous files, such as video or an installer. Random IOPS describes many small reads and writes, which is closer to what an operating system does when starting up or opening many apps. Samsung notes that results come from IOmeter tests, and that performance varies with firmware version and system configuration.

Sustained writes

The brand explains that its top write speeds are measured with Intelligent TurboWrite active, which uses a fast cache region. After that region fills, sequential writes continue at up to 2,000MB/s on the 1TB model. This matters mostly for very large transfers; for typical use the cache is rarely exhausted.

PCIe 4.0 and backward compatibility

Samsung says the 980 PRO offers twice the data transfer rate of PCIe 3.0 while remaining compatible with PCIe 3.0. It also advises checking whether your system supports PCIe 4.0, through the Intel or AMD website, to get the best from the drive. In a PCIe 3.0 slot it should still work, though the slot's lower bandwidth limits the speed.

Thermal control

High-speed SSDs produce heat, and when they get too warm they typically slow themselves down. Samsung says the 980 PRO uses nickel coating to help manage the controller's heat level, and a heat spreader label to provide thermal control of the NAND chip. This is a passive approach. It adds no height, so the drive suits slots with limited clearance. Some motherboards and laptops add their own heatsink as well.

Form factor

The drive uses the M.2 2280 format, roughly 80 mm long and 22 mm wide. Samsung says the compact design optimizes power efficiency, which is useful in laptops and small-form-factor builds. It attaches directly to the board, with no cables.

Who it suits

It suits desktop builders with a PCIe 4.0 M.2 slot, upgraders who want a quicker boot drive, and gamers loading large game files. It's also a candidate for creative work involving big video or image files, and for data-heavy tasks.

What to check before you buy

• Slot support: confirm your device has an M.2 slot for NVMe drives in the 2280 length.
• PCIe generation: check whether the slot is 4.0 or 3.0 in your system's manual.
• Console use: compatibility with games consoles is not stated in the listing, so check the console maker's requirements before choosing a drive.
• Capacity: 1TB suits a system drive plus a moderate library, but you may want more space for large collections.
• Cloning and backup: back up your data first, and follow the motherboard manual and Samsung's software instructions.

The short version

• Samsung 980 PRO 1TB, model MZ-V8P1T0B/AM, a PCIe 4.0 NVMe M.2 SSD.
• Rated at up to 3,500MB/s sequential reads and up to 690K IOPS random reads.
• Backward compatible with PCIe 3.0, but fastest in a PCIe 4.0 slot.
• Nickel coating and a heat spreader label for thermal control.
• Compact M.2 2280 shape, installed directly on the motherboard.
