Advanced Components

Only the latest components were selected for the S3 series,  Hynix's advanced 14nm process triple level cell NAND flash memory and a SMI 2254 controller. These components combined allow the S3 Series to deliver sequential read/write speeds of up to 550/520 MB/s, with random read/write speeds of up to 92K/79K IOPS. Compared to the sluggish, traditional hard drives, this is a remarkable level of performance!.

Great Capacity

Our proprietary, industry-leading PlexNitro technology uses SLC cache, which means the S3 does not need to reserve over-provisioning space, giving you accelerated read/write speeds. This also means users have accesss to the full capacity of the drive. Take a 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) and o?ers 3 capacity options: 128GB, 256GB and 512GB. 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 ?exible choice.

Exclusive Technologies


PlexNitro, Plextor’s exclusive cache acceleration technology, is developed especially for TLC SSD. It works by utilizing so called "PlexNitro Cache" as a buffer to improve the read and write speeds of TLC SSD, without taking away from user capacity as over provisioning. Plextor remains committed to providing the “Full Capacity” SSD products of 128GB, 256GB, and 512GB instead of 120GB, 240GB, and 480GB.


Plextor's PlexVault software is aimed to provide a more secure space and complete control privileges. Even if you are using a computer with others, you can still store your private data via PlexVault, safely and securely hidden on the computer, as long as the computer is equipped with a Plextor SSD.


The storage capacity of SSDs is always a key point of consideration. Plextor's PlexCompressor utilizes custom, smart-compression technology that gives the user more storage capacity without impacting user experience and system performance.


PlexTurbo is an intelligent SSD RAM caching solution, using system RAM to accelerate SSD storage performance. It boosts the service life of the SSD while vastly accelerating access speed performance. (Recommend DRAM capacity: 32GB)
