That is printed on Seagate T10 SAS drive.

Interesting, maybe look up the drive model on the site (or supplier) and see if they mention 10K limits.

can not find exact docs for this but here are two links to related info: <br />

The main question I want to know is, RPM = Performance ??

This is so confusing...<br />
For some hard drives, &nbsp;it says 15K rpm drive but 10K performance. What does it mean?

What does it mean for a hard drive with 15K rpm but 10K performance?

Storage devices include any device used for storing and retrieving digital information. Hard disk drives (HDDs) use one or more rigid ("hard") rapidly rotating disks (platters) coated with magnetic material. Data is accessed in a random-access manner, meaning that individual blocks of data can be stored or retrieved in any order and not only sequentially. The primary competing technology for secondary storage is flash memory in the form of solid-state drives (SSDs), but HDDs remain the dominant medium for secondary storage due to advantages in price per bit and per-device recording capacity. CD-RW (Compact Disc-ReWritable) is a digital optical disc storage format that allows information to be stored outside the mechanical HDD.

Storage Hardware

Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. In addition to local storage devices like CD and DVD readers, hard drives and flash drives, solid state drives can hold enormous amounts of data in a very small device. Cloud services and other new forms of remote storage also add to the capacity of devices and their ability to access more data without building additional data storage into a device.
