Intel XM25-M Features

The Intel X18-M/X25-M SATA Solid State Drive (SSD) delivers leading performance in industry standard 1.8” and 2.5” form factors while simultaneously improving system responsiveness for mobile applications over standard rotating drive media or hard disk drives. By combining Intel’s leading NAND flash memory technology with our innovative high performance controller, Intel delivers an SSD for Native Serial Advanced Technology Attachment (SATA) hard disk drive drop-in replacement with enhanced performance, reliability, ruggedness and power savings. Since there are no rotating platters, moving heads, fragile actuaters, or unnecessary delays due to spin-up time or positional seek time that can slow down the storage subsystem significantly, the Intel X18-M/X25-M SATA SSD enables fast read/write access times and a significant I/O and throughput performance improvement as compared to rotating media or hard disk drives.

The Intel X18-M/X25-M SATA SSDs primarily target SATA based laptop PCs, highly rugged mobile client devices, as well as thin and light, mini/sub-notebooks. Key attributes include high performance, low power, increased system responsiveness, high reliability and enhanced ruggedness as compared to standard mobile SATA hard drives. Intel X18-M/X25-M SATA SSDs are available in 1.8” and 2.5” form factors that are electrically, mechanically, and software compatible with existing 1.8” and 2.5” Serial ATA slots and cables. Our flexible design allows interchangeability with existing mobile hard drives based on the SATA interface standard.

Nonrecoverable Read Errors
The nonrecoverable read error rate will not exceed one sector in the specified number of bits read. In the extremely unlikely event of a nonrecoverable read error, the drive will report it as a read failure to the host; the sector in error is considered corrupt and is not returned to the host.

Mean Time Between Failure
The Mean Time Between Failure (MTBF) is 1,200,000 hours and is calculated based on a Part Stress Analysis. It assumes nominal voltage, with all other parameters within specified range.

Power On/Off Cycles
The power on/off cycles of the X25-M is rated at 50,000 cycles. A cycle is defined as power being removed from the drive, and then restored. Most host systems remove power from the drive when entering suspend and hibernate as well as on a system shutdown.

Minimum Useful Life
A typical client usage of 20 GB writes per day is assumed. Should the host system attempt to exceed 20 GB writes per day by a large margin for an extended period, the drive will enable the endurance management feature to adjust write performance. By efficiently managing performance, this feature enables the device to have, at a minimum, a five year useful life. Under normal operation conditions, the drive will not invoke this feature.
