1) no external power supply: minimal power consumption of the micro hard drive, connect the USB can be used, if an interface that not enough power to connect the two interfaces is certainly OK, and directly addresses the Hard Drive Caddy
external power supply trouble. So the future of hard drive-based MP3 might not need the battery can be connected to the computer.
2) long life: higher than the hard disk technology to make to ensure that its service life can be repeated wiping write more than 300 000 times, usually stable for five years.
3) Large capacity: to know, an area of only 1 inch micro hard disc as a whole, but also phone cards 1/3 area, the mainstream capacity has reached a level of 1-4GB-level, this year more 15GB (1 inch) and 60GB ( 1.8 inches) of products available, whether it is for the camera, or data storage are Zhuozhuo surplus.
4) with a cache: This is not just for the needs of the shock absorber, but an important guarantee to improve the data transfer rate, shock absorbers can be done by the external memory, cache, micro hard drive speed will become more slow, general product data cache with 128KB capacity.
5) high-speed transmission: more energy-saving, small size may raise doubts as to the data transmission speed of the micro hard drive, but we can be assured that the micro hard drive has a 3600-4200 RPM (Rotation per minute, r / min), the fastest has 4500 RPM. . Of course, due to the disc, small size, same speed, data transfer rate than the average hard disk is lower. Although the small size, heat dissipation is not easy, but they all have the automatic power saving mode, can take the initiative to reduce the heat, so that high speed can be more lasting.
6) high shock resistance: Due to the special design of the micro hard drive, its ability to shock than the average notebook hard drive a lot, their heads loaded unload technology, so that the impact resistance up to 1500G (non-working state) and 175G (working state ). Even with the low-end reading device to read and hard drive, dual protection, and also to avoid the internal hard drive have been hit. Not only as a micro hard drive MP3, digital cameras, laptop computers, PDAs, GPS and other portable devices can also be thought to provide a reliable storage performance.
7) USB 2.0 high-speed external transmission: When you use this high-capacity micro hard drives store songs, pictures, video, video, applications and files will be others to exchange data, then a fast transmission channel is essential. USB 2.0 is the compatibility of the most widely external interface standards, can achieve a transmission speed of 480 Mbps, approximately 60MB / s speed. Although USB1.1 can also be reluctant to use, Imagine, such a large-capacity data storage, transmission flows must also large, so we try to choose those of USB 2.0 micro hard drive MP3.
8) interface, extensive compatibility: micro hard drive with ordinary hard drives are compatible with compatible with a variety of industry-standard hard disk interface, which is mainly determined by the control chip to make it applicable to a variety of handheld devices. Therefore, we will see the CF card, PCMCIA, USB 2.0, ATA parallel port of the micro hard drive for possible future Serial ATA and SCSI's.
