HDD/SSD failure prediction. Calculation of stochastic and statistics using secp256k1.

Welcome to SorachanCoin [SORA]

What is SorachanCoin?
What is FromHDDtoSSD by SORA Network?

Are you scanning a drive?
Recently, SSD/NVMe has joined as a new factor in addition to HDD.
But ... SSD/NVMe inspection is very complicated.

SSD/NVMe "states fluctuate" compared to HDD that can be simply checked for sector reading, so such inspections do not give accurate values. Therefore, we pursued SSD/NVMe inspection by processing the probability distribution using the Blockchain.

From now on, SSD/NVMe will also have a huge capacity. Inspection is so important.

About SSD/NVMe scanning [Catch Ghost-like bad sectors ... i-sector]

We will use Blockchain and statistics to determine the scan of SSD/NVMe with "uncertain sectors" when a failure approaches. "Uncertain sectors" will be placed as "i-sector", and will wait until they are confirmed.

From there, we will utilize the knowledge of blockchain.
Below, FromHDDtoSSD v3.0(Build:5380) SSD/NVMe statistics scan with Blockchain.

FromHDDtoSSD also comes with all the basic features of the wallet, therefore you can operate everything just here. The network fee for this scan is approximately 0.02 - 0.04 SORA, Fee will be assigned to the miners reward in the next block.

statistical scan [with i-sector] to SSD/NVMe (via SORA Network)

About HDD scanning

There is no problem if HDD in the conventional inspection (only checking if a sectors read-able).
Because, it can always be processed with a converging constant.

Due to this property, it matches the result using SORA Network. in other words, we don't need SORA Network for HDD. But ... is that true?

The following theorem is helpful in this regard check.
* Identify theorem

fullscan to HDD (only checking if a sectors read-able)

Let's phase the scan results. full-scan and stat-scan.

A, fullscan to SSD/NVMe [only checking if a sectors read-able]


B, Equalize this result(A) to a statistical scan [with i-sector].
The analysis result below graph is significantly reduced. This indicates, that the inspection accuracy is low with only checking if a sectors read-able. This phenomenon denotes the cause of the accident that the data was lost immediately despite being inspected.


C, statistical scan to SSD/NVMe [with i-sector]
Using statistical scan, the scanning accuracy is improved and it turns out that this drive is no problem.


D, fullscan to HDD [only checking if a sectors read-able]


E, Equalize this result to a statistical scan [with i-sector].
The analysis results in the graph below show normality.
In the case of HDD, it shows that the results of fullscan and statistical match. Because, fullscan is enough if the case of HDD. The proof is the identity theorem.
