FAQ

Q.

What is a TRIM command?

A.

TRIM is a command that boosts the performance of SSDs.
In a SSD, an erase command does not delete the actual data written to a block.
So the TRIM command is used to delete the data contents of the block.
This allows immediate writing of new data to the same block on the SSD, keeping the highest level of performance of the SSD.

Q.

What is an ECC?

A.

ECC stands for Error Correction Code and is a technology that detects and corrects errors that are caused by issues such as noise and device fault in the data reading and writing processes of a NAND Flash Memory. (The NAND Flash Memory is the component of a SSD that handles data input and output.)

Q.

What is S.M.A.R.T.?

A.

S.M.A.R.T stands for Self-Monitoring, Analysis, and Reporting Technology and is an internal monitoring system for HDDs and SSDs.
With S.M.A.R.T., various problems and errors in a SSD can be identified and prevented.

Q.

What is RAID?

A.

RAID stands for Redundant Array of Independent Disks and is a technology that uses two or more disks (such as a SSD and a HDD) for data storage to enhance performance and security.

Q.

What is DEVSLP?

A.

DEVSLP is a power mode that reduces unnecessary power consumption by lowering the stand-by power when the system is not in use.
With better power efficiency than a regular stand-by mode, a SSD with a DEVSLP mode can lengthen the battery life of your laptop.


Q.

What is over-provisioning?

A.

Over-provisioning (OP) refers to allocating some data space of a SSD for endurance and performance-enhancing purposes.
While OP takes up some storage space, it improves the endurance and performance of a SSD.

Q.

What is SATA 6 Gb/s (also known as SATA3)?

A.

SATA 6 Gb/s, also known as SATA3, is a third-generation SATA that offers up to 6 Gb/s of data transfer speed and is a type of interface that connects a computer and a storage device.
HDDs and SSDs are the main drives that support SATA 3 interface.

Q.

What is a SSD interface?

A.

The interface of a SSD is a point of connection between two systems or devices.
The term is used for both hardware and software.
A SSD interface is the hardware and software connection between a PC and a SSD.
A hardware interface is sometimes used interchangeably with the term form factor, meaning the size and the shape of the component that physically connects to a device.

Q.

What is wear leveling?

A.

The NAND flash memory component of a SSD stores data.
Wear leveling is a technique that prolongs the lifespan of the NAND flash memory by avoiding writing (i.e. storing data) in the same blocks repetitively and instead storing data in less heavily used locations.
This technique allows the NAND flash memory to evenly use all data blocks, thereby increasing the lifespan of a SSD.

Q.

What is MTBF?

A.

MTBF stands for meantime between failures, which is the average time between data failures.
In other words, it means the average time between one data error and the next in an HDD or an SSD.
