Toshiba's HAMR and MAMR mechanical hard drive technologies both exceeded the 30TB mark, with the latter achieving 11 platters for the first time in the industry
According to news from this site on May 15, Toshiba recently announced that it successfully demonstrated a 32TB HAMR mechanical hard drive and a 31TB MAMR mechanical hard drive.
Notes on this site:
HAMR is Heat Assisted Magnetic Recording, the full name is Heat Assisted Magnetic Recording, which enhances magnetic recording capabilities by locally heating the disk with near-field light;
And MAMR It means microwave-assisted magnetic recording, the full name is Microwave Assisted Magnetic Recording, which uses microwaves to enhance the magnetic recording capabilities of mechanical hard drives.
Toshiba’s 32TB HAMR mechanical hard drive adopts a 10-platter design and uses SMR shingled magnetic recording technology, which makes its storage density the same as Seagate’s Magic Color Box 3+ The HAMR platform is basically the same, and the latter's 10-disk SMR version also has a capacity of 32TB.
Toshiba expects to begin sampling its HAMR mechanical hard drive in 2025. Foreign media Blocks & Files reported in a report that the capacity of these sample products will be 28~30TB, not reaching 32TB, so it may be a traditional CMR magnetic recording version.
Toshiba confirms that its 31TB MAMR mechanical hard driveis the first in the industry to implement an 11-platter design, with SMR and improved signal processing technology to promote the storage of this mechanical hard drive The density reaches 2.8TB per platter. In the press release, Toshiba praised its long-term close cooperation with platter manufacturer Resonac Corporation (reorganized from the former Showa Denko SDK) and magnetic head manufacturer TDK.
The above is the detailed content of Toshiba's HAMR and MAMR mechanical hard drive technologies both exceeded the 30TB mark, with the latter achieving 11 platters for the first time in the industry. For more information, please follow other related articles on the PHP Chinese website!

How Toshiba sets USB boot options for USB boot
Feb 11, 2024 am 09:27 AM
The use of CDs to install systems has become less and less common, and is now replaced by the more convenient and faster U disk installation method. To use a U disk to install the system, in addition to making a Professor U U disk boot disk, you also need to set the computer to boot from the U disk. Start to enter the system installation interface. Nowadays, most computers support U disk quick startup. You only need to press the hotkey during startup to choose to boot from the U disk. Here is a summary of the startup item setting shortcut keys for different motherboards and computers of different brands. Required tools: U disk startup disk 1. List of startup hotkeys for various brands of motherboard desktops, brands of all-in-one computers, and laptops: 2. How to use the startup hotkey to set up U disk startup with one click: 1. Put the prepared U disk Professor starts the U disk and inserts it into the computer USB interface, turns on or restarts, press
What is the abbreviation of mechanical hard drive?
Aug 25, 2022 pm 04:21 PM
The full English name of mechanical hard disk is "Hard Disk Drive", or "HDD" for short. The reason why a mechanical hard drive is called a mechanical hard drive is because it is completely made of mechanical structure inside. A mechanical hard drive is mainly composed of platters, heads, platter shafts, control motors, head controllers and other mechanical devices. The advantages of mechanical hard drives are large capacity, affordable prices, and relatively easy data repair, while the disadvantage is that the transfer rate is relatively It is lower, has poor shock resistance, has relatively high power, and is relatively large in weight and volume.
A giant in the hard drive field: Seagate releases a 30TB mechanical hard drive composed of 10 3TB platters
Jan 18, 2024 am 08:06 AM
According to news from this site on January 17, Seagate recently officially released the first-ever 30TB mechanical hard drive ExosXMozaic3+, which is the largest HDD hard drive to date. It will initially be targeted at the ultra-large-scale enterprise market and data centers, and will be sold to end users in the future. It does not require any professional hardware for use. According to foreign media TechRadar reported today, Seagate executive vice president and chief commercial officer BSTeh revealed in an interview that the company has used some "original" internal technologies to successfully achieve a breakthrough of loading more TB capacity per disk. It uses "the world's smallest and most sensitive" magnetic field reading sensor to read data on the hard disk, and the 12-nanometer integrated controller is claimed to be 3 times more efficient than previous solutions.

Is hdd a mechanical hard drive?
Nov 22, 2022 pm 04:02 PM
HDD is a mechanical hard drive. The full name of mechanical hard disk in English is "Hard Disk Drive", or "HDD" for short. The reason why it is called mechanical hard disk is because it is completely made of mechanical structure inside. A mechanical hard disk is mainly composed of a platter, a magnetic head, a platter shaft, a control motor, a magnetic head controller and other mechanical devices. Mechanical hard drives are located in dust-free factories throughout the production process. Any tiny particle of dust falling on the disk surface will have a devastating blow to the entire disk when it is working at thousands of revolutions per minute.
Comparison of solid state drives and mechanical hard drives
Feb 26, 2024 pm 06:21 PM
Advantages and Disadvantages of Solid State Drives and Mechanical Hard Drives In recent years, solid state drives (SSD) have gradually come into public view and are widely used in personal computers, servers and other fields. In comparison, mechanical hard disks (HDDs), as traditional storage devices, also have advantages in terms of reliability and cost-effectiveness. This article will conduct a comparative analysis of the advantages and disadvantages of solid-state drives and mechanical hard drives to help readers better choose a storage device that suits their needs. First of all, solid-state drives have obvious advantages in terms of read and write speeds. Since SSD uses flash storage media, it has faster reading and writing speeds.
Mechanical hard disk has entered its 70th year, looking back on the wandering years
Jan 22, 2024 pm 01:24 PM
This website reported on January 20 that since IBM launched the world's first digital hard drive, traditional mechanical hard drives have been ups and downs for nearly 70 years. Digital storage analyst Tom Coughlin teamed up with industry insider Tom Gardner to chart the revenue of traditional mechanical hard drives since the late 1950s. Note from this site: IBM released the world's first computer hard drive in 1956, which was larger than a refrigerator. It weighs over a ton. It looks a bit like a massive cylindrical air conditioning unit. This groundbreaking hard drive was called the IBM 305 RAMAC, short for Random Access Computing Control, when it was finally released in 1956 after five years of research and development by IBM.
