Renice X5A series 2.5" SATA3 SSD supports AES 256bit encryption, SED, TCG OPAL2.0

To protect your data security, there are many ways to do with it, hardware and software based encryption methods to realize it. As know BIOS can set password, or PC motherboard can set password (if supports PCM), moreover, the SSD drive can set password. Take Renice X5A series 2.5" SATA3 SSD for example, because Renice X5A SSD supports AES encryption, SED, TCG OPAL2.0, then you can set password through "Rescue System", the password is stored in the SSD drive, no one can read your data even it was stolen, it need your password to access to the SSD. Then you might want to know that why need to ask for your password seems it stores in the SSD? Because the password is encrypting into other numbers/words, e.g. you set "123456" as password, but it might store as "^%$##@*" through hash. Someone might ask is it safe if SSD drive only supports AES encryption?  The answer is NO, let's say that, if the SSD only supports  AES encryption but don...

Will the Input Voltage affects the Nand Flash of Solid State Drives (SSDs) ?

Image
In ITS (Intelligent Transportation Systems), PIS (Passenger Information System) and other embedded in-vehicle application, such as video surveillance, data recorder…usually or sometimes the voltage changes unstably, SSD as embedded memory and storage device when doing data video recording is aggressively affected by the unstable input voltage. First of all, please let me introduce RBER (Raw-Bit Error Rate), RBER is the Bit Error Rate before ECC (Error Correction Code) performing, reflects the initial reliability of Nand flash. The higher RBER, the less reliability of Nand flash. Then, how Input Voltage Affects the Nand Flash of SSD? Firstly, per 0.3V as a voltage difference in set time, the below graph is 3.3V-3.6V fluctuation. (1) When setting 2.7V - 3.V (standard voltage range of NAND flash), the RBER of NAND flash is 10^(-5.850), which is in normal range. (2) When setting as 3.6V - 3.9V, the RBER begins to increase, reach at 10^(-5.845). (3) When Voltage ran...

Renice: the Physical Destruction of SSD

Image
SSD Physical Destruction video: (https://www.youtube.com/watch?v=IAJvNfo2MpY) It’s not the worst burning in the video, other components are also burned and you could see the fire if press destruction button repeatedly. Here are several questions that you might want to know after watching the video. Q1, Is the Nand flash totally destroyed?  Yes. Q2, It seems the burning takes long time, can it be faster?       Yes. Burning time is controlled by singlechip, so the time not only can be set freely but also ensure complete destroy. Our test result shows that 10s can destroy all Nand flash (only for approved flash model). Q3, How long does the burning take?       Press the button for more than 5 seconds to trigger the physical data destruction function and start burning the NAND flashes, each Nand flash burning will take 5 seconds. Q4, Only through the button to trigger Physical Destruction function?  ...
