Product Description

Delkin Devices’ S218 Series 1.8” SATA SSD is the ideal HDD replacement for embedded applications, delivering industrial temperature storage in a compact SFF-8144** compliant form factor. Both SLC and MLC NAND options are available, in a wide array of capacities, to address applications ranging from an OS load to video recording. The S218 Series is rugged, built to withstand shock, vibration, and harsh environmental conditions.

As with all Delkin industrial products, the S218 Series is built with a controlled bill of materials, with the flash, controller and firmware locked in the part number. Delkin also understands that life cycle management is critical for industrial customers. Every possible measure is taken to extend product life cycles, but when the inevitable EOL does occur, Delkin has an advance notification process which gives customers the opportunity to place a last time buy and qualify a replacement part.

Delkin recognizes that an off-the-shelf part may not always be the best fit, and provides many customization options – ranging from custom labels, serialization, content and image loading, conformal coating, custom testing, even a complete custom design. Contact us to ask how we can customize a drive for your application.

In addition to the 1.8” SATA SSD, other SATA form factors Delkin offers are the S225 2.5” SSD, mSATA (MO-300B), mini-mSATA (MO-300B mini), SlimSATA (MO-297) and CFast

**SFF-8144 controlled by the Small Form Factor Committee.

mSATA (MO-300B)

When a SATA-based design calls for a board-level storage solution, the mSATA (JEDEC MO-300B standard) is the true embedded option selected by many engineers.

Mini mSATA (MO-300B Mini)

For real estate constrained hosts needing a true embedded SATA storage module, Mini mSATA (JEDEC MO-300B Mini standard) is the ideal solution, delivering up to 64GB of SLC or 128GB of MLC in less than 8 cm2 (1.25 in2.)

SlimSATA (MO-297)

Utilizing the same connector as a standard 2.5” HDD or SSD, the uncased SlimSATA form factor (conforming to the JEDEC MO-297 standard) is an excellent alternative for embedded applications not restricted to the mechanical outline of a traditional hard drive.

For embedded platforms which have used CompactFlash as a boot drive or other storage medium, and now face a migration from PATA to SATA due to a processor change, CFast is a logical choice for new designs.
