Toshiba Corporation is a Japanese multinational electronics company headquartered in Minato, Tokyo, Japan. Its diversified products and services include power, industrial and social infrastructure systems, elevators and escalators, electronic components, semiconductors, hard disk drives (HDD), printers, batteries, lighting, as well as IT solutions such as quantum cryptography which has been in development at Cambridge Research Laboratory, Toshiba Europe, located in the United Kingdom, now being commercialised. It was one of the biggest manufacturers of personal computers, consumer electronics, home appliances, and medical equipment. As a semiconductor company and the inventor of flash memory, Toshiba had been one of the top 10 in the chip industry until its flash memory unit was spun off as Toshiba Memory, later Kioxia, in the late 2010s.
Western Digital Corporation is an American computer drive manufacturer and data storage company, headquartered in San Jose, California. It designs, manufactures and sells data technology products, including data storage devices, data center systems and cloud storage services.
Plextor is a Taiwanese consumer electronics brand, best known for solid-state drives and optical disc drives.
Input/output operations per second is an input/output performance measurement used to characterize computer storage devices like hard disk drives (HDD), solid state drives (SSD), and storage area networks (SAN). Like benchmarks, IOPS numbers published by storage device manufacturers do not directly relate to real-world application performance.
In computing, a hybrid drive is a logical or physical storage device that combines a faster storage medium such as solid-state drive (SSD) with a higher-capacity hard disk drive (HDD). The intent is adding some of the speed of SSDs to the cost-effective storage capacity of traditional HDDs. The purpose of the SSD in a hybrid drive is to act as a cache for the data stored on the HDD, improving the overall performance by keeping copies of the most frequently used data on the faster SSD drive.
HGST, Inc. was a manufacturer of hard disk drives, solid-state drives, and external storage products and services.
OCZ was a brand of Toshiba that was used for some of its solid-state drives (SSDs) before they were rebranded with Toshiba. OCZ Storage Solutions was a manufacturer of SSDs based in San Jose, California, USA and was the new company formed after the sale of OCZ Technology Group's SSD assets to Toshiba Corporation. Since entering the memory market as OCZ Technology in 2002, the company has targeted its products primarily at the computer hardware enthusiast market, producing performance DDR RAM, video cards, USB drives, power supplies, and various cooling products. SSD devices with the OCZ brand that are using SATA III, PCI Express, Serial attached SCSI and USB 3.0 interfaces, for both client and enterprise applications are currently being produced. OCZ Storage Solutions was dissolved on April 1, 2016 and absorbed into Toshiba America Electronic Components, Inc, which later then became Kioxia.
A solid-state drive (SSD) is a solid-state storage device. It provides persistent data storage using no moving parts.
JMicron Technology Corporation is a Taiwan based fabless technology design house based in Hsinchu, Taiwan. As a manufacturer of integrated circuits, they produce controller chips for bridge devices.
Toshiba Samsung Storage Technology Corporation is an international joint venture company of Toshiba (Japan) and Samsung Electronics. Toshiba used to own 51% of its stock, while Samsung used to own the remaining 49%. The company specialized in optical disc drive manufacturing. The company was established in 2004.
A trim command allows an operating system to inform a solid-state drive (SSD) which blocks of data are no longer considered to be "in use" and therefore can be erased internally.
A hybrid array is a form of hierarchical storage management that combines hard disk drives (HDDs) with solid-state drives (SSDs) for I/O speed improvements.
Write amplification (WA) is an undesirable phenomenon associated with flash memory and solid-state drives (SSDs) where the actual amount of information physically written to the storage media is a multiple of the logical amount intended to be written.
SandForce was an American fabless semiconductor company based in Milpitas, California, that designed flash memory controllers for solid-state drives (SSDs). On January 4, 2012, SandForce was acquired by LSI Corporation and became the Flash Components Division of LSI. LSI was subsequently acquired by Avago Technologies on May 6, 2014 and on the 29th of that same month Seagate Technology announced its intention to buy LSI's Flash Components Division.
The Intel X25-M was a line of Serial ATA interface solid-state drives developed by Intel for personal computers, announced in late 2008. The SSD was a multi-level-cell solid-state drive available in a 2.5" form factor, came in 80 GB and 160 GB capacities and utilized NAND flash memory on a 50 nm process. The second-generation SSD which was called the "X25-M G2". The X25-M G2 was also available in a 2.5" form factor and 80 GB and 160 GB capacities, but with NAND flash memory on a more efficient 34 nm process.
Greenliant Systems is an American manufacturer of NAND flash memory-based solid state storage and controller semiconductors for embedded systems and data center products. Greenliant Systems was founded by Bing Yeh in 2010, and is headquartered in Santa Clara, California along with offices in North America, Europe and Asia.
SATA Express is a computer bus interface that supports both Serial ATA (SATA) and PCI Express (PCIe) storage devices, initially standardized in the SATA 3.2 specification. The SATA Express connector used on the host side is backward compatible with the standard SATA data connector, while it also provides two PCI Express lanes as a pure PCI Express connection to the storage device.
Kioxia Holdings Corporation, simply known as Kioxia and stylized as KIOXIA, is a Japanese multinational computer memory manufacturer headquartered in Tokyo, Japan. The company was spun off from the Toshiba conglomerate as Toshiba Memory Corporation in June 2018. It became a wholly owned subsidiary company of Toshiba Memory Holdings Corporation on March 1, 2019, and was renamed Kioxia in October 2019. In the early 1980s, while still part of Toshiba, the company was credited with inventing flash memory. In the second quarter of 2021, the company was estimated to have 18.3% of the global revenue share for NAND flash solid-state drives. The company is the parent company of Kioxia Corporation.
