Product Overview The top choice for next-generation SSD upgrade! The Plextor S3 solid-state drive series uses the latest technologies and components, including our proprietary PlexNitro cache technology. It is combined with intelligent SSD software technologies to provide a high-value SSD masterpiece that meets your computing expectations.

The Best Price-Performance Ratio
Satisfy your expectations for entry-level SSDs with the highest performances at affordable prices. The Plextor S3's advantages come from Plextor's advanced technologies, combined with high-quality components and proprietary firmware. The S3 series offers solid-state drives with the highest price-performance ratio.

New Processes for Advanced Components
Only the latest components were selected for the S3 series namely, Hynix's advanced 14nm process triple level cell NAND flash memory, and SMI 2254 controller. These components combined allows the S3 Series to deliver sequential read/write speeds of 550/520 MB/s with random read/write speeds of 92K/79K IOPS. Compared to the sluggish and traditional hard drives, this is a remarkable level of performance. Despite being entry-level devices, their professional quality standard is nonetheless worth noting.

Real Capacity of High Speed Cache
Use the SSDs full storage capacity! The proprietary industry-leading PlexNitro technology uses SLC cache design, which means the S3 does not need to reserve over-provisioning space, thus leading to accelerated read/write speeds. This means the users can use the full capacity of the drive. Take 128GB SSD as an example: after deducting the over-provisioning space used by other brands, only about 120GB of space will be left. With the PlexNitro performance optimization technology,, however, the full 128GB of space can be used, with no reduction at all.

Ideal for Custom PC Building and Upgrades
The S3 series comes in two form factors - SATA 2.5-inch (S3C) and M.2 2280 (S3G) . It can fully satisfy the installation requirements of desktop and laptop devices, as well as other devices that use SSDs. This makes the S3 series the most flexible choice.

Plextor's High Quality Product Guarantee
The S3 Series boasts of Plextor's consistent guarantee of the highest quality standards. It has passed rigorous inspections with the most advanced SSD testing equipment in the world; not a single error or fault is allowed (Zero Error). It also uses the "Plextor endurance testing mechanism" to simulate a range of professional read-write scenarios, to ensure stability and data security for users. Features • Advanced technologies and high quality components - Hynix 14nm triple level cell NAND and SMI 2254 controller IC.
• Exclusive PlexNitro performance optimization technology.
• Supports -PlexTurbo, PlexCompressor, and PlexVault.
• 3x faster than typical Hard Disk Drive-sequential read/write speed of up to 550/520 MB/s and random read/write speeds of 92K/79K IOPS.

The arrival of the solid-state drive (SSD) has revolutionised the speed at which modern PCs perform common tasks. This is because SSDs have no moving parts, compared to larger, bulkier mechanical drives, thus they store information on memory chips. This means that accesses, reads and writes are many, many times faster
