The Truth About Hard Drive RPM (Rotations Per Minute)
solved How does the motherboard know what RPM to spin a PWM fan at? The latter are traditionally reserved for larger devices, such as servers or disk array controllers. As the article listed by OP could have stated if it's author hadn't been such a jacka**, you can get better performance from a HDD by partitioning the OS and programs Very useful in many applications, such as dual booting or keeping the system drive (that has your OS on it) separate from your data (games, music, etc..) smithereenMay 30, 2009, 1:33 this contact form
External HDDs remained popular for much longer on the Apple Macintosh. In an... Later drives were designed to fit entirely into a chassis that would mount in a 19-inch rack. Data transfer rate (read/write) can be measured by writing a large file to disk using special file generator tools, then reading back the file. http://www.sevenforums.com/hardware-devices/65010-truth-about-hard-drive-rpm-rotations-per-minute.html

A typical HDD design consists of a spindle that holds flat circular disks, also called platters, which hold the recorded data. 7200 Rpm Hard Drive Laptop This is precisely what's happening to PC enthusiasts who think they're getting a great deal when they buy in to the hard drive RPM myth. Enterprise HDDs Typically used with multiple-user computers running enterprise software.
For example, a RAID1 array has about half the total capacity as a result of data mirroring, while a RAID5 array with x drives loses 1/x of capacity (which equals to
It does not directly equate to higher data transfer rates, which is commonly assumed.
