3D NAND is a type of non-volatile flash memory in which the memory cells are stacked vertically in multiple layers.
Powerguard
Power Loss Protection (PLP)
Flash mit DRAM Puffer
A DRAM chip in a flash module functions the way a cache does in a hard disk.
Advanced LDPC ECC Engine
The advanced LDPC ECC engine is an error-correcting mechanism that is superior to its predecessors. As the Flash controller has evolved, it has become more complex, and thus error correction has become more precise on each minute portion of data. LDPC can correct more errors per page than before, thus sustaining the lifespan of the SSD.
DEVSLP
DEVSLP (Device Sleep) is a feature in SATA devices that reduces power consumption by setting the device to a "low power" (or sleep) mode. This device sleep state consumes less power than the traditional low power mode, which needs to remain powered to receive the wake-up command.
End-to-End Data Protection
An effective methodology to ensure data integrity. End-to-end data protection is a comprehensive protection that covers the entire pathway for data transmission from the host computer to the SSD and back. Having multiple points of protections ensures that data integrity is preserved, especially since the protection detects and corrects any errors that may occur in these long transmission journeys.
Dynamic Thermal Throttling
Dynamic thermal throttling is a temperature-adjustment mechanism that prevents the SSD from overheating. When the disk reaches a maximum temperature threshold, this feature automatically adjusts performance, slowing it down so that the device can cool off. to drop Once the temperature decreases to the predetermined acceptable levels, transfer speed will rise back to its optimum performance level.
Reliability
Military Grade
Cervoz's Military Grade SSD is designed to protect the most sensitive data in extreme environmental conditions.
Cervoz FlashMonitor
Cervoz FlashMonitor is a proprietary monitoring software developed in-house to monitor flash disk health.
Reliability-Optimized MLC
The Reliability-Optimized MLC (RO-MLC) technology uses MLC NAND but with a special firmware that manipulates cell storage at the block level simulating SLC technology.
Bad Block Management
Bad block management is regularly performed on NAND flash memory.Bad block management is a built-in management program that detects and tags bad memory blocks within the SSD, so that no data is written into them. Once marked, data in these bad blocks will be transferred to the good blocks, preserving the data integrity and overall performance and durability of the SSD.
Over-Provisioning
SSD overprovisioning can provide higher efficiency and better endurance.Over-provisioning is a function that sets aside space for the SSD's provisional use. These free blocks allow the SSD to operate at normal speed while other functions such as wear-leveling or garbage collection are taking place. The blocks also serve as replacements for bad blocks that may be detected by bad block management.
Page Mapping
Page mapping is an advanced technology that writes in data at a smaller unit than the original block-based mapping. Since a page is smaller than a block, mapping based on pages increases speed and accuracy and reduces the wear on the NAND Flash. Overall, this preserves and lengthens the life span of the SSD.
S.M.A.R.T.
Self-Monitoring, Analysis, and Reporting Technology. S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology) is a diagnostic system that is convenient in gauging the health of HDDs and SSDs. The technology is built-in and actively monitors a set of data related to the drive's reliability and durability. S.M.A.R.T. provides users with an accurate idea of when the drive may need to be replaced.
TRIM Support
The TRIM command is used with Active Garbage Collection to clean up SSDs to ensure they continue to work quickly. TRIM support is a command function that allows the Operating System to inform the SSD controller of the locations of data that are no longer in use and can be wiped internally. Without it, these blocks of data will not be deleted but will rather be marked as “not in use.” Once the TRIM command is given, the controller wipes these blocks and frees up space. Whenever the computer is idle, it will erase the blocks filled with data that are no longer needed to make them available for subsequent writes.
WAF Reduction
Minimize Write Amplification to Maximize SSD Lifetime. WAF (Write Amplification Factor) is the numerical value that denotes the number of writes actually taking place in relation to the number issued by the controller. To reduce the WAF, the NAND controller writes in the data in a sequential order to reduce the movement within the Flash module that takes place later on when the data needs to be erased. With fewer movements, the SSD sustains less wear and enjoys a longer lifespan.
Wear Leveling
SSD controllers use a technique called wear leveling to distribute writes as evenly as possible across all the flash blocks in the SSD. Wear leveling is a technical process with which an SSD can prolong its longevity. With wear leveling, the Flash controller distributes all P/E cycles evenly to each block, making sure that they reach their P/E threshold at the same time as opposed to prematurely.
Durability
Wide Temperature
Cervoz's Wide Temperature flash and memory modules are designed for extreme environments, capable of withstanding temperatures from -40˚C to 85˚C.
Conformal Coating
Conformal coating is a thin protective film applied to products to protect against moisture, dust, chemicals, and sunlight.
Anti-Vibration Fill
The anti-vibration fill is a filling that can keep Flash and DRAM modules intact and help protect them from shock and vibration.
Isolation
Isolation describes the design of modular expansion cards whereby the input and output circuits are electrically and physically separated. The design prevents any interference or harm to the device from the power source, and overall increases the safety of the device to users.
Security
Write Protect
Write protection is used to denote the locking mechanism which prevents modification or deletion of data on a storage device. Write protect is a function that, when switched on, makes data read-only and prevents any tampering, leaks or malicious use by unauthorized third parties. With the function switched on, the NAND Flash is protected from any action, thus protecting the sensitive data from being overwritten or deleted.
Quick Erase
For emergency data erase –the process only takes a few seconds. Quick erase is a function that deletes all data stored on the module within seconds of being activated. Once data has been erased, the module is restored to its original, factory conditions and can be reused.
Self-Physical Destruction
The data is permanently destroyed and unrecoverable. Self-physical destruction uses a high voltage input to physical burn out and destroy the NAND Flash IC. This function permanently erases any data stored and renders the module unusable.
AES-256 Bit Encryption
AES (short for Advanced Encryption Standard) is a symmetric block cipher used to protect sensitive information. As a block-based encryption, AES stores data in blocks as large as 256 bits per block. AES-256 bit encryption supports the largest bit size and is virtually impenetrable by brute force. It is considered the strongest encryption standard.
