Protect Your Data with Cervoz’s Thoughtful Power Loss Protection Technology

In the fast-paced world of computing, solid-state drives (SSDs) have become indispensable storage components for individuals and businesses alike. These high-performance storage solutions offer enhanced reliability and superior speed compared to traditional hard disk drives (HDDs) that rely on traditional spinning-platter technology. However, SSDs also have their own vulnerabilities, particularly when it comes to data loss caused by power outages. Here, we will explore how Cervoz SSDs employ power loss protection techniques to provide an extra layer of protection, ensuring the safety and integrity of your valuable data. Advanced Power Loss Protection for Uninterrupted Operations One of the primary concerns with SSDs is the risk of data loss during sudden power outages. Cervoz addresses this issue through a thoughtful Power Lost Protection mechanism, integrating key techniques: Safeguard, Voltguard, Circuitguard and Powerguard. These features minimize the risk of data loss and SSD crashes while enhancing the stability and reliability of Cervoz SSDs. Safeguard– Protecting Data Integrity with VDT and Firmware Mechanism With the Cervoz Safeguard function, its VDT (Voltage Detector) mechanism enables SSD to proactively detect a sudden power failure, immediately notify the controller, and stop receiving commands to avoid mapping table and NAND firmware corruption. When the system power is resumed, this mechanism can ensure the ability of NAND firmware to rebuild the mapping table, reducing the possibility of data loss. When new data is written to SSD, NAND firmware always updates the mapping table to NAND flash; that’s what we named backup information. With a preserved backup information copy of the good data, the firmware and mapping table can seamlessly recover to a previously known reliable state if a sudden power loss corrupts the current write operations. This ensures data integrity and safeguards against potential corruption caused by unexpected power interruptions. Simply put, the Safeguard function is just like a shield, proactively preventing data loss caused by power disruptions and safeguarding your valuable data on the NAND flash. Voltguard & Circuitguard – Preventing Damage from Abnormal Currents and Voltages Cervoz SSDs go beyond safeguarding against power outages by incorporating integrated protection measures including OVP (Over Voltage Protection), UVP (Under Voltage Protection), and OCP (Over Current Protection). These intelligent functions enable SSDs to detect and respond swiftly to abnormal currents and voltages. The Cervoz Voltguard function enables SSDs to start-up within a stable voltage range, preventing damage caused by unstable voltage. Additionally, through the Cervoz Circuitguard function, when the SSD current is abnormal, it will automatically power off, preventing potential damage to the SSD or entire system operation, and ensuring data integrity. Once the abnormal conditions pass, the SSD rapidly restores normal operating conditions, ensuring seamless and uninterrupted operations. These protections provide primary detection mechanisms for monitoring the power offered by the host. Voltguard Circuitguard Powerguard for Data Safety – Ensuring Data Integrity with Powerguard Technology Cervoz's Powerguard technology guarantees a consistent power supply for an extended duration immediately when detecting an unexpected power decline. When the working voltage drops below standard, the Power Management IC will immediately activate the protection mechanism and deliver sufficient electricity to SSD, allowing all data in the DRAM buffers to be entirely written back to NAND Flash securely and integrally. Typically, the average time for the backup power discharge to complete data storage takes 40ms, varying based on the complexity or size of the computing task. Cervoz's Powerguard technology can provide a maximum buffer time of up to 250ms, ensuring the data has enough time to be written entirely. The Cervoz Powerguard provides ample time for complete data storage, minimizing the risk of data loss.

IoT Security

We are living in a “smart” age. Virtually everything we own is or can be a smart device, from a smartphone in our pockets toa smart TV on our walls and smart cars on the road. Put simply, smart devices, also known as IoT devices, are connected via networks such as Bluetooth or Wi-Fi and function in conjunction with each other to make life easier for users. At home, this IoT ecosystem enables residents to turn appliances on and off from the comfort of their beds; at work, it makes most operations more efficient and productive. The problem is that whenever things are connected to a network, the threat of hacking surfaces. Whether it is an unsecured device, a vulnerable network or advanced hacking, smart devices are susceptible to ways of hacking that their non-smart counterparts are not. In this smart age, how do we keep our devices and our data protected? We have compiled a list of tips from both our in-house experts and credible, online sources that work for both domestic and industrial IoT devices. 1. Set strong passwords The cardinal rule of IoT security is to set strong passwords and frequently change them. Passwords are the locks to the front door of your devices, so they are the most basic line of protection when it comes to keeping devices safe. 2. Update devices regularly When the front door is locked, hackers will look for other openings—“windows of opportunity”—into the device. Software updates are designed to identify any such loopholes and close them up. As such, it is important that your devices are set to regularly check for updates and to install them in a timely manner. 3. Secure the network Network connectivity, the very thing that makes an IoT device useful, is what makes it susceptible to hacking. This is why securing the network connection is crucial in protecting IoT security. This step includes turning on encryptions, setting up firewalls and being aware of settings that may allow guests or outsiders to access the network. There are even discussions about segmenting networks, which has been suggested to be more appropriate for IIoT devices. 4. Monitor closely for any irregular events Monitoring our devices can mean a number of things. For personal devices, this could be regularly running scans for virus or threats. For industrial machines and systems, there are teams dedicated to attempted attacks. Specific software exist for the purpose of monitoring and protecting industrial machines and systems. At Cervoz, for instance, we have developed an in-house software, the Cervoz FlashMonitor, to go with any of our SSD products so that our customers can detect whenever there are anomalies in data read and accessed. 5. Maintain cyber literacy Keep updated on the cybersecurity threats out there. For companies especially, make sure that employees are educated on the different ways that hackers may try to gain access to sensitive company data.
