Hard disk data recovery industry's good days are over: Intel SSD 610p up to 2TB
Intel, which has been favored in the SSD solid-state drive market, has focused on the enterprise market for the first two years. However, starting this year, Intel will increase its investment in the consumer market. The SSD 600p is the first to introduce 3D TLC. Consumer products of flash memory, as well as SMI Huirong master, M.2/PCI-E specification blessing, have been popular since its launch.
The life cycle of SSD 600p will continue until the third quarter of 2018, but in the fourth quarter of 2017, Intel will launch an upgraded SSD 610p, which is still M.2 2280 form factor, with capacities of 128GB, 256GB, 512GB. A new 2TB is added in addition to 1TB, which is still 3D flash, but more details are not clear.
It is worth noting that the two are not substitutes and will exist in the market at the same time.
In addition, Intel will launch the BGA integrated package version of the SSD 600p in the third quarter of 2017, with a capacity of 128/256/512GB.
There will also be SSD 545s series, 2.5 inch / M.2 specifications, SMI master and 16nm 3D TLC flash memory, the maximum capacity of 2.5 inch 2TB, M.2 1TB.
As for the high-end SSD 750 with U.2 and PCI-E specifications, it will soon be delisted, but the successor is undecided.
No regrets? SSD data recovery Quest
Solid-state drives (SSDs) are popular among high-end players for their ultra-high-speed read and write speeds, but SSD drives have also exposed some immature performance. There have been examples of firmware gates and performance degradation. The latest tests on the Techgage website show that SSD drives have encountered new challenges in data recovery, a problem that is particularly acute with SSDs that support TRIM commands. In view of this, the editor compiled this article and hoped to attract the attention of the players. At present, there is no other evaluation to prove this problem. I don't have any SSDs to repeat the verification. I hope that players who are using SSDs will discuss more in the comments and pay attention to backing up their important data.
Have you upgraded your PC to a new generation of configurations (such as multi-core CPUs, SSD solid-state drives) and are complacent about the high performance of new computers? Indeed, the performance of today's PCs is getting stronger and stronger, but one is not careful, this beast worth $2,000 will also make you sigh. If you like the author and like to load a bunch of applications after entering the desktop, then you need to be careful.
The problem stems from the SSD solid state drive. This 2.5-inch NAND hard drive can greatly improve the performance of the computer. The startup speed is even faster. Users who have used the SSD hard disk will find a huge difference between them and the ordinary mechanical hard disk. However, the focus of this article is not on the performance of SSD drives, but on the problems that SSDs may bring, especially the TRIM instructions introduced in Win7 systems may have a negative impact on data recovery. This issue is still controversial, but it is still worth our attention and discussion.
Solid state drives have also had problems before, remember Intel's brick door? At first, people thought that this was only the risk of Intel's SSD hard drive, but it turned out that many SSD hard drives on the market have the same inherent problems.
Almost the vast majority of storage devices have the following similar steps when deleting files: once the user deletes the file, the index pointing to the specific location of the data on the hard disk is deleted (for mechanical hard disks, LBA logical block addressing). For example, if you manage your favorite movie storage location on a piece of paper for management purposes, one day you accidentally burned the paper, in fact you only lost a piece of paper, the actual movie still in. Usually, our data storage is like this. When deleting a file, only the index of the file is deleted. The specific file still exists on the hard disk.
It is also because the actual data is still stored on the hard disk, data recovery has the possibility of operation, of course, the premise is that the user does not cover the new data in the original location. Once a user accidentally deletes an important file, the data recovery software has a high probability of successfully recovering the file. This is not uncommon for a mechanical hard drive. With the rise of SSD hard drives, the method of restoring data has not changed, but the unique use of SSDs makes data recovery face new challenges.
Mechanical hard disks can overwrite data at any time without affecting the read and write performance of the hard disk. Even after a few years of use, the read and write speeds will not change significantly. In contrast, SSDs suffer from performance degradation after a period of use due to the different working principles of NAND flash.
We can use the process of disk fragmentation to explain this problem. The system writes a bunch of data to a certain block of the disk. When it is not needed, the user deletes the data and saves other files in the same location. The system saves the file in a fixed-size block (the windows system defaults to 4KB as a data unit), and the newly saved file does not necessarily fill the original occupied block, assuming a picture The size is 6KB, it takes 2KB block and 2KB of another block, and the remaining 2KB space may be occupied by another word document. If the user deletes the image file, but the word document is not affected, it still needs to occupy The remaining 2KB, so it will produce disk fragmentation.
As the usage time increases, the disk fragmentation will increase, which will lead to the performance degradation of the disk. Therefore, we need to regularly defragment the disk and transfer the space occupied by the fragment, but the disk defragmentation is not solved for the solid state disk. All of the problems.
Once the new data needs to be written in the original location, the traditional mechanical hard disk needs to overwrite the new data write, and the SSD hard disk must first clear the original data to write the new data to the hard disk. This is also the SSD hard disk. One reason for higher performance, and the process of performing clean-write is also the main role of the TRIM instruction.
Microsoft introduced a new TAM command based on the ATA command in the Win7 system. Once there is a disk read or write such as deleting files, formatting or ignoring files, the system will issue a command to the SSD hard disk to clear the data in the block. This process is simple, but it is very practical. Regardless of whether the user deletes the file or formats the SSD hard disk, the TRIM command will clear the data and index. In a sense, the SSD hard disk is equivalent to a new state, and there is no problem of performance degradation.
The role of the TRIM directive is also the origin of this article, and most people ignore the negative impact of the TRIM directive. Users enjoy the benefits of TRIM and unwittingly reduce the possibility of data recovery to zero. As mentioned above, there is no problem in data recovery on the mechanical hard disk and the solid state hard disk that does not support the TRIM command. Only the original location does not write new data, the user only needs to select the appropriate software to basically recover the accidental deletion. file.
Data recovery can be a problem in TRIM-enabled SSDs. Once you delete a file (and then empty the Recycle Bin), your data may never be recovered. Because of the existence of the TRIM command, the SSD hard disk will completely empty that block after the user deletes the data, instead of just deleting the index and retaining the data like a traditional mechanical hard disk.
I can't confirm whether the TRIM instruction will cause the data on the mechanical hard disk to be unrecoverable. If there is a conclusion, then the average consumer can't perform such data recovery. Of course, if there is a suitable tool, data recovery is not impossible. In a sense, we can think of NAND flash as the memory (RAM) of the computer. Once the memory is powered off, the data will disappear. In some cases, recovery can be initiated by using special means to ensure that the memory is constantly powered.
