Logical device interfaces define the command sets used by operating systems to communicate with SSDs and host bus adapters HBAs. Configurations[ edit ] The size and shape of any device is largely driven by the size and shape of the components used to make that device. Traditional HDDs and optical drives are designed around the rotating platter s or optical disc along with the spindle motor inside. If an SSD is made up of various interconnected integrated circuits ICs and an interface connector, then its shape is no longer limited to the shape of rotating media drives.

Some solid state storage solutions come in a larger chassis that may even be a rack-mount form factor with numerous SSDs inside.

They would all connect to a common bus inside the chassis and connect outside the box with a single connector. For desktop computers with 3. Other types of form factors are more common in enterprise applications. An SSD can also be completely integrated in the other circuitry of the device, as in the Apple MacBook Air starting with the fall model.

Hard Drive Sizes and Interfaces

Standard HDD form factors[ edit ] The benefit of using a current HDD form factor would be to take advantage of the extensive infrastructure already in place to mount and connect the drives to the host system. It remains electrically compatible with the PCI Express Mini Card interface specification, while requiring an additional connection to the SATA host controller through the same connector.

DOM devices emulate a traditional hard disk drive, resulting in no need for special drivers or other specific operating system support.

DOMs are usually used in embedded systemswhich are often deployed in harsh environments where mechanical HDDs would simply fail, or in thin clients because of small size, low power consumption and silent operation.

Box form factors[ edit ] Many of the DRAM-based solutions use a box that is often designed to fit in a rack-mount system. The number of DRAM components required to get sufficient capacity to store the data along with the backup power supplies requires a larger space than traditional HDD form factors.

The result is an easy-to-install SSD with a capacity equal to drives that typically take a full 2.

The main benefits of BGA SSDs are their low power consumption, small chip package size to fit into compact subsystems, and that they can be soldered directly onto a system motherboard to reduce adverse effects from vibration and shock.

Traditional SSD benchmarks tend to focus on the performance characteristics that are poor with HDDs, such as rotational latency and seek time. However, SSDs have challenges with mixed reads and writes, and their performance may degrade over time.

SSD testing must start from the in use full drive, as the new and empty fresh, out-of-the-box drive may have much better write performance than it would show after only weeks of use.

Enterprise flash devices EFDs are designed to handle the demands of tier-1 application with performance and response times similar to less-expensive SSDs.

The wear-leveling algorithms are complex and difficult to test exhaustively; as a result, one major cause of data loss in SSDs is firmware bugs.

Comparisons reflect typical characteristics, and may not hold for a specific device. New drives are supposed to retain data for about ten years. SSDs are not suited for archival use. If kept in a dry environment at low temperature, HDDs can retain their data for a very long period of time even without power.

However, the mechanical parts tend to become clotted over time and the drive fails to spin up after a few years in storage. Start-up time Almost instantaneous; no mechanical components to prepare.SSD reliability in the real world: Google's experience. Using data from millions of drive days in Google datacenters, a new paper offers production lifecycle data on SSD reliability.
