What is SSD storage?

Solid state drive (SSD) storage uses non-volatile solid state chips that feature flash memory cells to store data on a long-term basis. Unlike traditional hard disk drives (HDDs), which use magnetic platters spinning at high speeds to using an actuator arm reminiscent of a record player, SSDs require no moving parts.

When were SSDs first available?

The use of flash memory for longer-term storage has been around since the 1950s, but those solutions were generally in mainframes or larger minicomputers. They also required battery backups to preserve the contents of the memory when the machine was not powered by the host, as those solutions used volatile memory.

Applications for SSDs

There are multiple benefits to using SSDs for production storage applications. Because SSDs have no moving mechanical components, they use less power, are more resistant to drops or rough handling, operate almost silently, and read quickly with less latency.

How to choose the right SSD for your needs

Over the past few years, there have been several changes to SSDs. One of the most recent updates is the use of the PCIe interface (a low-latency computer expansion bus also known as a peripheral component interconnect express) instead of over other interface technologies, such as serial advanced technology attachment (SATA).

What does the future hold?

In the short term, capacities will continue to ramp up, while the cost per GB for SSDs will continue to decrease. New form factors that increase the number of parallel data transmission lanes between storage and the host bus will emerge to increase the speed and quality of the NAND storage medium.

Solid state drives (SSDs) had origins in the 1950s with two similar technologies: magnetic core memory and card capacitor read-only store (CCROS). These auxiliary memory units (as contemporaries called them) emerged during the era of vacuum-tube computers. But with the introduction of cheaper drum storage units, their usage ceased.

Architecture and Function

The key components of an SSD are the controller and the memory to store the data. Though the primary memory component in an SSD was traditionally DRAM volatile memory, it is now more commonly NAND flash non-volatile memory. Other components play a less significant role in the operation of the SSD and vary among manufacturers.


Every SSD includes a controller that incorporates the electronics that bridge the NAND memory components to the host computer. The controller is an embedded processor that executes firmware-level code and is one of the most important factors of SSD performance. Some of the functions performed by the controller include:


SSDs based on volatile memory such as DRAM are characterized by ultrafast data access (generally less than 10 microseconds) and are used primarily to accelerate applications that would otherwise be held back by the latency of flash SSDs or traditional HDDs.

Cache or Buffer

A flash-based SSD typically uses a small amount of DRAM as a cache, similar to the cache in hard disk drives. A directory of block placement and wear leveling data is also kept in the cache while the drive is operating. Data is not permanently stored in the cache.

Battery or Super Capacitor

Another component in higher performing SSDs is a capacitor or some form of battery. These are necessary to maintain data integrity such that the data in the cache can be flushed to the drive when power is dropped; some may even hold power long enough to maintain data in the cache until power is resumed.

Host Interface

The host interface is not specifically a component of the SSD, but it is a key part of the drive. The interface is usually incorporated into the controller discussed above. The interface is generally one of the interfaces found in HDDs. They include:

How much did a 1TB SSD cost in 1977?

A Bulk Core setup, including a controller board and 256KB of storage, cost $9700 in 1977, which is equivalent to $36,317 today. At that pricing rate, a 1TB SSD (which costs about $1100 today) would have cost $152 billion.

How much data can a flash drive hold?

Called simply Flashdisk, Digipro’s plug-in board for IBM PC compatibles could hold up to 16MB of data. It shipped in January 1990 in 2MB, 4MB, 6MB, and 8MB capacities, with the high-end version selling for $5000. An Israeli flash company called M-Systems created its own flash-drive prototype in 1989, but didn’t commercialize it until 1995, making Flashdisk the first flash SSD to market.

What was the purpose of RAM SSDs in the 1990s?

Most RAM SSDs of the 1990s contained both a battery backup and a hard disk that would automatically store the RAM disk’s contents if power were lost.

How much does a STC 4305 hold?

The STC 4305, which emulated the IBM 2305 drum-storage unit, represented a significant boost in the capacity of SSDs. A 4305 cabinet could hold up to 45MB of data, which it stored using charge-coupled devices, a novel approach at the time. Such a system, including the required dual controller cards, would set you back $400,000 in 1978 (about $1.5 million in today’s dollars). If that sounds like a lot for storing the equivalent of one moderately sized smartphone app, consider that this device was 52 percent cheaper than the drum-storage equivalent IBM sold.

What is Transcend flash?

In 2003, Transcend introduced a line of flash modules that emulated Parallel ATA IDE hard drives, which were common in consumer PCs at the time. Each module, much smaller than a traditional PATA hard drive, included a 40- or 44-pin PATA connector and shipped in 16MB to 512MB capacities. Larger capacities followed in later years.

When was the first solid state drive invented?

In 1976 , Dataram introduced the world’s first solid-state drive, the Bulk Core. The product consisted of a rack-mount chassis–measuring 19 inches wide by 15.75 inches tall–that held up to eight individual memory boards, each packed with 256KB of RAM chips. In total, the Bulk Core system could provide a massive 2MB of storage for minicomputers such as the DEC PDP-11 and the Data General Nova. Data-access times ranged from 0.75 milliseconds to 2 milliseconds, depending on the controller board. (Today, SSDs regularly have 0.06ms access times.)

When did Axlon start selling RAM?

In 1982 , Nolan Bushnell’s toy company Axlon began selling a line of RAM disks for home PCs such as the Apple II and Atari 800. The Ramdisk 320, intended for the Apple II, retailed for $1395 and held 320KB of data in a box the size of a Disk II drive. Since it stored data on conventional RAM chips that would lose the data if powered off, the 320 included a 3-hour rechargeable battery.

Why are SSDs important?

Additionally, SSDs are drawing users’ attention worldwide due to its numerous advantages, such as fast read-write speed, no noise, lower consumption, portability, etc.

What is the advantage of an enterprise SSD over a client SSD?
