DOM plate

DOM electronic hard disk features: SSD capacity to 512 MB100% IDE compatible (40pin or 44pin) no noise sector size of 512 bytes with automatic error correction and rewriting advanced troubleshooting system operating system compatibility: with MS- DOS, Windows 98 system, Windows ME systems, Windows 2000 systems, Windows XP system, Windows CE system, NT system (year 2003 version) and LINUX compatible. IDE electronic drives Applications: network terminals (NC), lottery machines, set-top boxes (STB), firewall, onboard controllers (GPS), power monitoring equipment, terminals (POS), human-machine interface, digital hard disk video, industrial computers, industrial computer products Specifications Capacity: 8M, 16M, 32M, 48M, 64M, 80M, 96M, 128M, 256M, 512M, 1G, 2G, 4G temperature: 0 ~ 80 ° C (work) -25 ~ 80 ° C ( non-operating) Humidity: 8 to 95%, non-condensing (operating) 8 to 95%, non-condensing (non-operating) Noise: 0 dB (@ 1 meter) Vibration: 15 G maximum peak-to-peak (work) Maximum 15 G peak to peak (non-operating) Shock: Maximum 1000 G (working) Maximum 1000 G (non-operating) Power: DC input voltage: 3.3 V ± 5%, 5 V ± 10% Typical power consumption: Sleep: 200 uA ( 3.3 V); 500 uA (5 V) reading: 32 ~ 80 mA (3.3 V); read: 46 ~ 120 mA (5 V) write: 32 ~ 80 mA (3.3 V); writing: 46 ~ 120 mA (5 V) Performance: fully supports PIO MODE 4, ie, the maximum data transfer speeds of up to 16.6Mb / sec hibernation to write: 2.9 msec or more dormant to read: 5.6 msec or more reset read: typical 50 msec, 400 msec maximum data to / from the Flash disk Transmission speed: 4.0 MByte / sec burst to / from the host data transfer rate: 6.0 MByte / sec burst controller command to the House DRQ: 1.25 msec maximum life: 300,000 cycles per sector erase / write endurance MTBF (@ 25 ° C) : more than 1,000,000 hours DOM electronic hard disk sectors and the mechanical hard drive exactly the same: 512 bytes per sector, can withstand 300,000 write operations (read sector is no frequency limit). Frequent use DOM electronic hard disk, even within five years of the life cycle computer, use only a small part of the whole to its affordability. For example, a document of any size (from 512 bytes to drive maximum capacity) is a part of the drive writes, rewrites 3 times per hour, writing eight hours a day, 365 days a year to write, then make the drive here partially spent 34 years time. What are the advantages of electronic disk DOM: We know that electronic trading is a semiconductor chip used to store data, while the hard disk is the head, and other mechanical disk drives to record data, they have what advantages and disadvantages? With advances in technology, rapid development of modern hard disk capacity has grown from 20MB to now nearly 100GB, interface speed has also developed from the early PIO mode to the current DMA33 / 66 and the latest DMA100, but hard as a machine recording apparatus, its own seismic, and there is no ability to impact greatly improved, and in some high-vibration environments such as the car used in the computer equipment or workshop, a hard disk can not be competent, and otherwise easy to damage the hard disk body, the data will not be guaranteed, this case with electronic trading on the very appropriate. As a solid state storage device that uses a semiconductor chip to store data instead of relying on the head as hard to read as the high-speed rotation of the disc data. Therefore, a strong seismic performance. So in some industrial control movement in the case of computer equipment, electronic application is very general. Although the hard disk is smaller than normal, but due to very small SSD, power consumption is very low capacity SSD, so in some of the most demanding power consumption and space is cramped embedded occasions, SSD has it very unique advantage; combined with the current even Automation (LA), intelligent automation equipment terminal, network computer (NC), and other fields has matured, the embedded operating system, such as WINDOWS CE, NT EMBEDDED, EMBEDD LINUX, QNX and other widely used so SSD to become one of the device hardware design engineer is very beloved.
