Kietasis diskas (SSD) Adata ASU900SS-256GM-C, 2.5", 256 GB

A-Data Ultimate SU900 Series
Prekės aprašymas anglų kalba:

The Ultimate SU900 solid state drives implements 3D MLC NAND Flash and an SMI controller, offering capacities up to 2TB, high speed, and great reliability. It features intelligent SLC Caching and DRAM Cache Buffer to boost read/write performance up to 560/525MB per second. With the support of LDPC ECC and multiple data protection technologies, the SU900 provides high TBW (total bytes written) and instantly upgrades notebook and desktop PCs with superior stability, durability, and power efficiency. In addition, the SU900 is backed by a 5-year warranty for long-term reliability assurance.

Ample storage up to 2TB with 3D MLC NAND Flash

Implementing advanced 3D MLC NAND Flash and a high speed SMI controller, the SU900 features bigger storage capacities, higher efficiency, and more rugged reliability compared to 2D NAND SSDs. Thanks to the flexibility of 3D MLC NAND, we can offer the SU900 in diverse capacities, ranging from 256GB to 2TB. You get more choice for different needs, whether for an OS boot drive or a mass storage drive.

Intelligent SLC Caching and DRAM Cache Buffer

The intelligent SLC Caching algorithm allows NAND Flash memory to operate in single-level cell mode and boosts read/write performance. In addition, with the support of DRAM Cache Buffer, read/write performance can be as much as double that of solid state drives that lack a DRAM cache, or in other words that can't use onboard memory as an SSD buffer for high intensity tasks.

Outperforms HDDs with Massive Performance Gain

Utilizing high quality materials and advanced technologies, the SU900 outperforms traditional HDDs by a huge factor, with particular benefits in boot up and seek time, as well as overall much faster read/write throughput.

Advanced LDPC ECC Engine

LDPC (low density parity check) error correcting code has been implemented on the SU900, leading to a massive reduction in data errors and an equal increase in data integrity. It protects your valuable contents against corruption to a much greater extent than non-ECC SSDs or even SSDs that use basic BCH error correction. In addition, the SU900 has a program/erase cycle three times longer than standard SSDs due to incorporating native hard and soft decode. Together, these ensure improved durability and a longer SSD lifespan.

High TBW for excellent durability

Utilizing 3D MLC NAND flash, all SU900 models provide high TBW (Total Bytes Written) up to 800TB and random R/W speed up to 85K/90K IOPS. The SU900’s TBW rating outranks comparable models, indicating a longer-lasting SSD with a longer MTBF of 2 million hours (compared to 1.5 million hours on previous 2D NAND SSDs).

Multiple Data Protection Technologies

The SU900 supports multiple data protection technologies, including internal data shaping, software/hardware write protection options, early weak block retirement, and a global wear leveling algorithm to ensure data integrity and improve SSD stability.
