Above 1,000 feet (305 meters), the maximum temperature is derated linearly to 112°F (44°C) at 10,000 feet (3,048 meters).

Operating:

0° to 60°C (32° to 140°F)

 

 

Nonoperating:

–40° to 70°C (–40° to 158°F)

 

 

2.8.2Temperature gradient

Operating:

20°C per hour (68°F per hour max), without condensation

 

 

Nonoperating:

30°C per hour (86°F per hour max)

 

 

2.8.3Humidity

2.8.3.1Relative humidity

Operating:

5% to 90% noncondensing (30% per hour max)

 

 

Nonoperating:

5% to 95% noncondensing (30% per hour max)

 

 

2.8.3.2Wet bulb temperature

Operating:

37.7°C (99.9°F max)

 

 

Nonoperating:

40°C (104°F max)

 

 

2.8.4Altitude

Operating:

–60.96 m to 3,048 m (–200 ft. to 10,000+ ft.)

 

 

Nonoperating:

–60.96 m to 12,192 m (–200 ft. to 40,000+ ft.)

 

 

2.8.5Shock

All shock specifications assume that the drive is mounted securely with the input shock applied at the drive mounting screws. Shock may be applied in the X, Y or Z axis.

2.8.5.1Operating shock

These drives comply with the performance levels specified in this document when subjected to a maximum operating shock of 63 Gs based on half-sine shock pulses of 2 msec. Shocks should not be repeated more than two times per second.

2.8.5.2Nonoperating shock

The nonoperating shock level that the drive can experience without incurring physical damage or degradation in performance when subsequently put into operation is 350 Gs based on a nonrepetitive half-sine shock pulse of 2 msec duration.

ST3500641NS, ST3500841NS specifications

The Seagate ST3500841NS and ST3500641NS are robust hard drives specifically designed for enterprise environments, catering to the demanding needs of data centers, server farms, and storage solutions. These drives are part of Seagate's enterprise series and reflect a commitment to reliability, performance, and capacity.

One of the main features of the ST3500841NS and ST3500641NS is their impressive storage capacity. The ST3500841NS offers 500GB of storage, while the ST3500641NS provides a slightly lower capacity at 640GB. Both drives utilize a standard 3.5-inch form factor, making them suitable for a variety of server and storage configurations. They operate at a high spindle speed of 7200 RPM, which contributes to faster data access and overall improved performance compared to traditional 5400 RPM drives.

These drives are designed to sustain high workloads and feature a mean time between failures (MTBF) rating that ensures reliability over extended periods of operation. With their enhanced error correction capabilities, data integrity is maintained even under heavy loads, making these drives ideal for use in critical applications where data loss is not an option.

The integration of technologies such as Native Command Queuing (NCQ) enhances the performance of these drives in multi-user environments. NCQ allows the drive to optimize the order of read and write commands, reducing latency and improving overall throughput. Furthermore, the ST3500841NS and ST3500641NS both feature an SATA interface, supporting speeds of up to 3.0 Gb/s, which is the standard for modern storage solutions.

Another noteworthy characteristic of these drives is their energy efficiency. Despite their robust performance, the ST3500841NS and ST3500641NS are designed to consume less power, thereby reducing operational costs and contributing to a more sustainable data center environment.

In summary, the Seagate ST3500841NS and ST3500641NS are purpose-built for enterprise applications, offering a blend of capacity, performance, and reliability. Their advanced technologies, coupled with impressive MTBF ratings and energy efficiency, make them suitable for critical applications in various high-demand environments. Whether utilized in small server systems or large-scale data centers, these drives provide the robust performance that businesses require in today’s data-driven landscape.
