Q: What is the Seagate ST9146802SS?
A: The Seagate ST9146802SS is a 146GB 2.5-inch enterprise SAS hard disk drive designed for high-performance storage environments such as servers and data centers.
Q: What interface does this drive use?
A: This drive uses a Serial Attached SCSI (SAS) interface with a speed of 6Gb/s, ensuring fast and reliable data transfer.
Q: What is the spindle speed of the ST9146802SS?
A: The ST9146802SS operates at 10,000 RPM, delivering rapid access times and consistent performance for demanding workloads.
Q: Is this drive compatible with SATA controllers?
A: No, the ST9146802SS uses a SAS interface and is not directly compatible with standard SATA controllers. It requires a SAS controller or a SAS-compatible backplane.
Q: What is the form factor of this drive?
A: This is a 2.5-inch small form factor (SFF) drive, commonly used in enterprise servers and storage arrays where space efficiency is critical.
Q: What is the cache size of the ST9146802SS?
A: The drive features a 16MB cache buffer, which helps optimize performance during sequential read and write operations.
Q: What is the power consumption of this drive?
A: Typical power consumption is around 4.6 watts during read/write operations and approximately 3.2 watts when idle.
Q: Is the ST9146802SS hot-swappable?
A: Yes, the drive supports hot-swapping when used in a compatible SAS backplane or enclosure, allowing replacement without powering down the system.
Q: What is the average latency of this drive?
A: The average rotational latency for a 10,000 RPM drive is approximately 3.0 milliseconds.
Q: What operating systems support this drive?
A: The drive is supported by any operating system that can recognize SAS devices, including Windows Server, Linux, VMware ESXi, and Unix-based systems, provided the correct drivers are installed.
Q: Can I use this drive in a desktop computer?
A: While possible with a SAS controller card, the ST9146802SS is optimized for enterprise environments and may not offer the same consumer-friendly features as standard desktop drives.
Q: What is the expected lifespan of the ST9146802SS?
A: Enterprise drives like this are designed for 24/7 operation and typically have a mean time between failures (MTBF) of over 1.5 million hours.
Q: Does this drive support encryption?
A: The standard model does not include hardware encryption. Check the specific variant or firmware version for any encryption capabilities.
