Most HDDs in the early 1980s were sold to PC end users as an external, add-on subsystem. The subsystem was not sold under the drive manufacturer's name but under the subsystem manufacturer's name such as Corvus Systems and Tallgrass Technologies, or under the PC system manufacturer's name such as the Apple ProFile. The IBM PC/XT in 1983 included an internal 10MB HDD, and soon thereafter, internal HDDs proliferated on personal computers. Everything You Know About Disks Is Wrong". Storagemojo.com.

However, two independent studies by Carnegie Mellon University [135] and Google [136] found that the "grade" of a drive does not relate to the drive's failure rate.

For giant magnetoresistive (GMR) heads in particular, a minor head crash from contamination (that does not remove the magnetic surface of the disk) still results in the head temporarily overheating, due to friction with the disk surface, and can render the data unreadable for a short period until the head temperature stabilizes (so called "thermal asperity", a problem which can partially be dealt with by proper electronic filtering of the read signal). If you are using a computer equipped with at least one hard disk or solid state disk and you want to ensure that your data will be available any time, then the answer is YES.

The most recent Seagate roadmap pushes HAMR shipments into 2020, so they are now slipping faster than real-time. Western Digital has given up on HAMR and is promising that Microwave Assisted Magnetic Recording (MAMR) is only a year out. BPM has dropped off both companies' roadmaps.

The rate of areal density advancement was similar to Moore's law (doubling every two years) through 2010: 60% per year during 1988–1996, 100% during 1996–2003 and 30% during 2003–2010. [74] Speaking in 1997, Gordon Moore called the increase "flabbergasting", [75] while observing later that growth cannot continue forever. [76] Price improvement decelerated to −12% per year during 2010–2017, [77] as the growth of areal density slowed. The rate of advancement for areal density slowed to 10% per year during 2010–2016, [78] and there was difficulty in migrating from perpendicular recording to newer technologies. [79] Another option you may consider is removing the faulty drive and working completely from a USB drive or external hard drive. This allows you to connect to any computer and have the same setup. You could have a similar Windows setup from USB with these top Linux distros. Mellor, Chris (July 31, 2017). "NAND that's that... Flash chip industry worth twice disk drive biz". The Register .

A laboratory demonstration of a 1.33-Tb 3D NAND chip with 96 layers (NAND commonly used in solid state drives (SSDs)) had 5.5Tbit/in 2 as of 2019 [update], [165] while the maximum areal density for HDDs is 1.5Tbit/in 2. The areal density of flash memory is doubling every two years, similar to Moore's law (40% per year) and faster than the 10–20% per year for HDDs. As of 2018 [update], the maximum capacity was 16terabytes for an HDD, [166] and 100terabytes for an SSD. [25] HDDs were used in 70% of the desktop and notebook computers produced in 2016, and SSDs were used in 30%. The usage share of HDDs is declining and could drop below 50% in 2018–2019 according to one forecast, because SSDs are replacing smaller-capacity (less than one-terabyte) HDDs in desktop and notebook computers and MP3 players.

you want to maximize system stability, HDD performance and overall integrity, receive HDD alert on high temperature or low health Hard Disk Sentinel (HDSentinel) is a multi-OS SSD and HDD monitoring and analysis software. Its goal is to find, test, diagnose and repair hard disk drive problems, report and display SSD and HDD health, performance degradations and failures. Hard Disk Sentinel gives complete textual description, tips and displays/reports the most comprehensive information about the hard disks and solid state disks inside the computer and in external enclosures ( USB hard disks / e-SATA hard disks). Many different alerts and report options are available to ensure maximum safety of your valuable data. Bai, Zhaoqiang; Cai, Yongqing; Shen, Lei; Han, Guchang; Feng, Yuanping (2013).

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.The revenues for SSDs, most of which use NAND flash memory, slightly exceeded those for HDDs in 2018. [14] Flash storage products had more than twice the revenue of hard disk drives as of 2017 [update]. [15] Though SSDs have four to nine times higher cost per bit, [16] [17] they are replacing HDDs in applications where speed, power consumption, small size, high capacity and durability are important. [12] [13] As of 2019 [update], the cost per bit of SSDs is falling, and the price premium over HDDs has narrowed. [17] The factors that limit the time to access the data on an HDD are mostly related to the mechanical nature of the rotating disks and moving heads, including: a b "WD Red Desktop/Mobile Series Spec Sheet" (PDF).
