They read random data faster than disks and are therefore helpful in search applications.
Flash as a form of solid state storage is much faster for reading and writing data than the spinning disks in traditional disk drives.
The patents in questions were used in hard drive circuits to read data from high-speed disks.
Ordinary data centers use RAID 5 or 6 storage, which distributes data across 5 or 6 disks in the same server.

Some have predicted eventually 99% of data may be stored on spinning disks yet 99% of accesses will be happening on SSDs.
Companies frequently face data breaches when employees lose laptops and disks, but sharing and storing company documents on third-party cloud services carry their own risks, including phishing attacks.
Data accessed most frequently (often referred to as 'hot' data) is managed using speedy NAND flash to ensure fast response times, while data accessed less often ('cold' data) resides on the robust magnetic disks.

Data was stored on rewritable magneto-optical disks 2.5in (64mm) in diameter housed for protection in a square plastic shell.
That was also before CD drives that can record or "burn" data for a fraction of the price of Zip disks became prevalent.
WD's innovative hybrid technology pairs MLC NAND flash storage for fast SSD-like data throughput and instant-on responsiveness with magnetic disks for efficient, high-capacity storage.

The technology, called RAID (redundant arrays of independent disks), involves clever algorithms for dealing out data among an assortment of hard-disk platters.
Because consumers must walk back and forth from the computer to the television set to drag and drop files onto the TakeTV, SanDisk Vice President Eric Bone says TakeTV relies on the old-fashioned "SneakerNet"--the tried and true technique of marching across the living room with stored data, an operation that dates back to the days of floppy disks, burnable CDs and DVDs.
The movies and game data are on separate CDs, so you won't need to swap disks halfway through a mission.
It can hold up 340M bytes of data, or the equivalent of what could be stored on 200 standard floppy disks, IBM said.
Write caching would store data to be written on the HDD in flash memory initially until enough data was in the flash cache to do an efficient write to the HDD disks.
FORBES: New Seagate Solid State Hybrid Drive is Faster and Vaster
Among today's data-storage devices, magnetic tapes can degrade within a decade, while hard disks are expensive and need a constant supply of electricity to hold their information, creating huge need for power for the "data farms" behind cloud computing.

Decoupling refresh cycles lets data center customers purchase server compute nodes, which are essentially very small motherboards (processor, system memory, boot environment, management, and connection to a local network fabric), separately from rack-level data center network interfaces (1GbE and 10GbE), separately from mass storage (hard disks and solid-state drives).

Symform uses RAID (Redundant Array of Independent Disks) 96, which encrypts, shreds, and geographically scatters each fragment of data to 96 different devices.

For this, fast disks and often petabytes of it with the right software that makes it possible to find data down the road, is needed.
