HDD price per byte decreased at the rate of 40% per year during 1988–1996, 51% per year during 1996–2003 and 34% per year during 2003–2010. [23] [74] The price decrease slowed down to 13% per year during 2011–2014, as areal density increase slowed and the 2011 Thailand floods damaged manufacturing facilities [79] and have held at 11% per year during 2010–2017. [154] Rotational latency is incurred because the desired disk sector may not be directly under the head when data transfer is requested. Average rotational latency is shown in the table, based on the statistical relation that the average latency is one-half the rotational period. The platters in contemporary HDDs are spun at speeds varying from 4,200 RPM in energy-efficient portable devices, to 15,000rpm for high-performance servers. [52] The first HDDs spun at 1,200rpm [6] and, for many years, 3,600rpm was the norm. [53] As of November 2019 [update], the platters in most consumer-grade HDDs spin at 5,400 or 7,200RPM. Within a given manufacturers model the uncorrected bit error rate is typically the same regardless of capacity of the drive. [68] [69] [70] [71]

Time to access data can be improved by increasing rotational speed (thus reducing latency) or by reducing the time spent seeking. Increasing areal density increases throughput by increasing data rate and by increasing the amount of data under a set of heads, thereby potentially reducing seek activity for a given amount of data. The time to access data has not kept up with throughput increases, which themselves have not kept up with growth in bit density and storage capacity. Kheong Chn, Sann (2005).

Have another drive or device ready. You have two options here. You could buy a new hard drive and install it in your current computer, which is ideal if your device is still fairly new, such as one or two years. For older devices, it may be time to consider a new computer. Typically, a DSP in the electronics inside the drive takes the raw analog voltages from the read head and uses PRML and Reed–Solomon error correction [131] to decode the data, then sends that data out the standard interface. That DSP also watches the error rate detected by error detection and correction, and performs bad sector remapping, data collection for Self-Monitoring, Analysis, and Reporting Technology, and other internal tasks. Software reports hard disk drive or memory capacity in different forms using either decimal or binary prefixes. The Microsoft Windows family of operating systems uses the binary convention when reporting storage capacity, so an HDD offered by its manufacturer as a 1TB drive is reported by these operating systems as a 931GB HDD. Mac OS X 10.6 (" Snow Leopard") uses decimal convention when reporting HDD capacity. [117] The default behavior of the df command-line utility on Linux is to report the HDD capacity as a number of 1024-byte units. [118] MjM Data Recovery Ltd.

This depends on the age of your PC. If your PC's only a year or two old, it's much cheaper to buy a new hard drive. For older PCs, take a look at your other hardware. Is it still compatible with most newer apps and Windows 11? Mellor, Chris (September 3, 2019). "Western Digital debuts 18TB and 20TB MAMR disk drives" .

Nimbus Data. Archived from the original on December 31, 2018 . Retrieved February 20, 2019. Current hard drives connect to a computer over one of several bus types, including parallel ATA, Serial ATA, SCSI, Serial Attached SCSI (SAS), and Fibre Channel. Some drives, especially external portable drives, use IEEE1394, or USB. All of these interfaces are digital; electronics on the drive process the analog signals from the read/write heads. Current drives present a consistent interface to the rest of the computer, independent of the data encoding scheme used internally, and independent of the physical number of disks and heads within the drive. Over time, as recording densities were greatly increased, further reductions in disk diameter to 3.5" and 2.5" were found to be optimum. Powerful rare earth magnet materials became affordable during this period, and were complementary to the swing arm actuator design to make possible the compact form factors of modern HDDs.
