2.5″ PATA SSD (Solid State Drive)

2.5 inch PATA SSDamp inc’s 2.5″ PATA interface solid-state drive adopts advanced SSD controller and NAND Flash components. It is compatible with ATA-7 protocol and supports PIO-4, MWDMA-2 and UDMA-6 transfer rates. The SSD supports mainstream OS, such as Windows/ MAC/ Linux/ Unix/ Solaris/ Vxworks, and provides storage capacity ranging from 8GB to 128GB. It is widely used in the reinforcement computer, industrial control computer, embedded computer and national defense fields.

amp inc’s 2.5″ PATA interface solid-state drives carry out a series of strict temperature, vibration and shock tests in accordance with the standards of military equipment to make sure the products work in harsh environments.

Key Features (Flash Management):

  1. Advance Wear-Leveling Algorithm The NAND flash devices are limited by a certain number of write cycles. When using a file system, frequent file table updates is mandatory. If some area on the flash wears out faster than others, it would significantly reduce the lifetime of the whole device, even if the erase counts of others are far from the write cycle limit. Thus, if the write cycles can be distributed evenly across the media, the lifetime of the media can be prolonged significantly. The scheme is achieved both via buffer management and specific advanced wear leveling to ensure that the lifetime of the flash media can be increased,
    and the disk access performance is optimized as well.
  2. S.M.A.R.T Function S.M.A.R.T. is an acronym for Self-Monitoring, Analysis and Reporting Technology, an open standard allowing disk drives to automatically monitor their own health and report potential problems. It protects the user from unscheduled downtime by monitoring and storing critical drive performance and calibration parameters. Ideally, this should allow taking proactive actions to prevent impending drive failure. SMART feature adopts the standard SMART command B0h to read data from the drive. When the SMART Utility running on the host, it analyzes and reports the disk status to the host before the device is in critical condition.
  3. Built-in Hardware ECC The ATA-Disk Module uses BCH Error Detection Code (EDC) and Error Correction Code (ECC) algorithms which correct up to eight random single-bit errors for each 512-byte block of data. High performance is fulfilled through hardware-based error detection and correction.
