The Samsung PM981a series MZVLB1T0HBLR-000L7 is a one terabyte NVMe solid state drive built for laptop and desktop upgrades that demand fast boot times and quick file transfers. Manufactured in the compact M.2 2280 form factor, the drive uses Samsung's own V-NAND triple level cell flash paired with the in house Phoenix controller to deliver high throughput while keeping power draw low for thin notebook chassis. Its most distinctive specification is sequential performance, reaching up to thirty five hundred megabytes per second for reads and roughly three thousand megabytes per second for writes across the PCI Express third generation four lane interface running the NVMe one point three protocol. A second standout capability is random access performance, with the controller and firmware sustaining roughly five hundred eighty thousand read and five hundred fifty thousand write input output operations per second, numbers that translate into snappier application loading and smoother multitasking than older SATA based drives. Security minded users benefit from built in AES two hundred fifty six bit hardware encryption alongside TCG Opal two point zero support, letting the drive integrate with enterprise disk encryption software without a measurable performance penalty. Originally supplied as an original equipment component inside notebooks from major PC manufacturers, this drive drops into any system with a compatible M.2 PCIe NVMe slot, making it a straightforward replacement or capacity upgrade for an existing laptop or small form factor desktop build.

Key Features:

• Slim Compact Form Factor: The drive measures to the standard eighty millimeter length so it fits directly into thin laptop and small form factor desktop boards.
• High Speed NVMe Interface: A four lane PCI Express third generation connection running NVMe firmware reaches sequential read speeds of up to 3500MB/s.
• Strong Random Access Performance: The Phoenix controller sustains roughly 580000 read and 550000 write input output operations every second under load.
• Hardware Based Encryption: Built in AES 256 bit encryption alongside TCG Opal 2.0 support lets the drive integrate with enterprise security software easily.
• Advanced V NAND Storage: Samsung triple level cell flash memory provides the full 1TB of usable capacity for an operating system, programs, and files.
