Designed for use in entry-level Enterprise servers, typically for read-intensive and boot/logging applications, the 128GB X400 M.2 Internal SSD from SanDisk features a storage capacity of up to 128GB and a 1.5mm single-sided M.2 (2280) form factor. In addition to its server functionality, the X400 can also be used to store a variety of files including movies, photos, music, documents, and more on your compatible system. It connects to M.2 drive bays using its SATA III 6 Gb/s interface and delivers sequential read speeds of up to 540 MB/s, sequential write speeds of up to 340 MB/s, random reads of up to 93,500 IOPS, and random writes of up to 60,000 IOPS (In/Out Operations per Second).

With solid-state drive technology, you benefit from load and access times for your files and programs that are faster than a conventional 7200 rpm hard drive. As SSDs have no moving parts, they are also more durable than traditional hard drives and are better protected against damage from drops and bumps. Having no moving parts also means that SSDs receive less wear and tear, as there are no read or write heads for the drive media to come into contact with.

The 128GB X400 M.2 Internal SSD has been built using a 2nd generation TLC flash node. In addition to being compatible with the SATA III 6 Gb/s interface, this SSD is backwards compatible with SATA II 3 Gb/s and SATA 1.5 Gb/s interfaces. It also features an MTTF (mean time to failure) rating of up to 1.75 million hours, an endurance rating of 72 TBW (terabytes written), nCache 2.0 technology, DataGuard Client technology, LDPC error correction, and TCG Opal 2.0 support. Protection is provided by a limited 5-year warranty.

General Features

For Products Built Around High Capacities and Thin Form Factors
From ultrathin consumer notebooks to corporate platforms, the X400 SSD offers a 128GB storage capacity in a small form factor to deliver a variety of design and integration options for manufacturers and systems builders. With a 1.5mm single-sided form factor (M.2 2280 module), the X400's performance and capacity make it suitable for ultra-thin designs.
Responsiveness, Reliability, and Low Power
Built using SanDisk's 2nd generation TLC flash node, the X400 SSD offers quick responsiveness, high reliability, and low power for a seamless and productive user experience.
nCache 2.0 Technology Means Improved Performance
The X400 features nCache 2.0 technology, which boosts performance for fast burst and high sustained sequential write speeds. Its multi-tiered caching architecture uses a combination of SLC and TLC blocks to help maximize read/write operations and improve responsiveness and longevity, making it a suitable storage solution for multi-tasking and heavy workloads such as photo and video editing, as well as office productivity applications.
Durable with High-Grade Endurance
DataGuard Client technology and LDPC error correction mean that the X400 SSD delivers high reliability and endurance up to 72 terabytes written (TBW). A dedicated on-the-fly hardware core performs progressive error correction to help minimize the impact on latency and performance, while also maintaining low power usage.
TCG Opal 2.0 Support
TCG Opal 2.0 support means interoperability with 3rd party security Independent Software Vendors (ISVs). The X400 SSD includes Self-Encrypted Drive (SED) capabilities to help protect data at rest through hardware-based 256-bit AES encryption. Corporate IT customers have peace of mind knowing their business-critical data is protected, secured, and encrypted, while providing performance and reliability to its employees.
