2.8.5Shock

All shock measurements in this section are carried out at drive level. For all linear shock test, operating or nonoperating, the input shock level is measured at the frame of the drive at the specific location as indicated in Figure 3 below.

2.8.5.1Operating shock

The drive is subjected to 10 shocks for each direction. During the shocks, there must be a minimum delay of 3 seconds between shock pulses. Soft errors and automatic retries are allowed during the test. No data loss or permanent damage occurs during a half sine shock pulse of:

500 G, 2 msec

2.8.5.2Nonoperating shock

The nonoperating shock level that the drive can experience without incurring any physical damage when sub- sequently put into operation is 1500 Gs. The same applies for shock levels of 1500 G, 1 msec pulse duration on fresh drives for each level.

2.8.6Vibration

All vibration specifications assume that the drive is mounted securely in a fixture that does not have fixture resonances in the frequency test range.

ST740211DE-40GB, ST760211DE-60GB, ST730212DE-30GB specifications

Seagate, a renowned name in the storage solutions industry, has made significant contributions with its range of hard disk drives (HDDs) designed for various applications. Among these are the Seagate ST730212DE-30GB, ST760211DE-60GB, and ST740211DE-40GB models. Each of these drives brings unique features and technologies tailored to meet the demands of users seeking reliable data storage.

Starting with the Seagate ST730212DE-30GB, this drive offers a compact storage solution with a capacity of 30GB, making it suitable for handheld devices or applications where space is a premium. The ST730212DE utilizes a 2.5-inch form factor, which allows for easy integration into various devices while ensuring portability. This HDD is built with an average latency of 12 ms and a spindle speed of 4,200 RPM, which provides a decent performance for applications that require quick access to stored data. Its ATA interface ensures compatibility with a wide range of systems, providing flexibility for users.

Next in line is the Seagate ST760211DE-60GB, which doubles the storage capacity of the previous model to 60GB. The ST760211DE is designed for slightly more demanding applications, making it ideal for users who require additional storage without compromising on size. Similar to the ST730212DE, this drive features a 2.5-inch form factor and operates at a spindle speed of 4,200 RPM. Its enhanced capacity allows for more extensive media libraries, applications, and files, while the ATA interface maintains broad compatibility.

Finally, the Seagate ST740211DE-40GB strikes a balance between the two preceding models, offering 40GB of storage. This drive caters to those who need more than what the ST730212DE offers but do not require the full 60GB of the ST760211DE. With the same dimensions and spindle speed, the ST740211DE is versatile and can fit various applications, from laptops to gaming consoles, all while ensuring optimal performance.

All three models embody Seagate's commitment to reliability and performance.
