Important: Do not erase your SSD too frequently. Simply put, ATA Secure Erase command wipes data from SSD thoroughly and terminally, with no possibility to recover these data with known data retrieve techniques. Go further data on these blocks could be recovered by dedicated recovery tool.ДЄTA Secure Erase command works with SSD controller and tells it to reset all storage cells as empty (releasing stored electrons), thus restoring the SSD to factory default settings and write performance. As a result, some blocks on SSD like bad blocks and wear-leveling blocks will leave behind in the service. General format methods over-write data on SSD, but they cannot access all the storage areas on the SSD. However, this cannot happen on SSD.ДЄs we know, SSD stores data on NAND flash memory chips that are made of numerous blocks. In the past, when we donвЂ™t need files or documents anymore, weвЂ™ll delete them or even format the entire HDD for a second use. ATA Secure Erase and Format: whatвЂ™s the difference? WhatвЂ™s more, secure erase is a widely accepted effective and secure way to wipe all data to meet legal requirements. On the contrary, the operations like deletes and reformats will result in unanticipated progressive performance degradation of write operations on SSDs. Existing disk sanitization techniques originally used for hard drives do not work on SSDs. SSD has different internal architecture which makes its data cleaning very different. Some user also needs SSD Secure Erase when he sells the drive to others. Secure Erase commands are used as a data sanitization method to completely overwrite all the data on a hard drive, so that to restore SSD to вЂњfactory freshвЂќ level. Secure Erase is the name given to a set of commands available from the firmware on PATA and SATA based on hard drives. SSDs are read modify write, so setting a file to a bunch of zeros doesnt actually modify the original data, its still there in the nand, its just now that 'Sector' points to a different part of the SSD that has the new file with the zeros in it.Before you start SSD data wiping, you may want to have a brief understanding about Secure Erase. (this is also how iphones wipe their data too) no structure at all, and no way to ever recover the data. The data on the SSD is now a perfect distribution of random noise. The manufacturer utility just instructs the SSD to wipe that key. The key that encrypts all that data is stored internally to the SSD and is literally the key to reading the data back. Keeping the data random stops cells from degrading if a whole bunch is 1 or 0 ( or 3, or 15), and helps with reading the data back, as it provides the nand controller the range of voltages to effectively recover the data stored. Use the tool from the manufacturer of the SSD.ДЄLL (modern) ssds encrypt data written to the flash, not only as its useful for a security standpoint, but it also means that the data written to the flash is much more uniform distribution of 0 and 1, which is fairly important for MLC flash.

If it's a 1TB drive and below the TBW warranty, I'll rma it, otherwise, dispose. Found the drive holding up the raid array. Low and behold, DD erase either hangs or writes very poor like 2meg/sec. If I have a suspect drive or drives in a mirrored OS set, and I don't know which is causing grief but I'm getting lagging writes, I make a best guess on SMART data, yank that out of the array, secure erase, and then erase with DD.

It should be doing the full 400-500 meg/sec. If you suspect the drive might be having write issues, I also hit it with the erase with DD erase for a minute or so, and watch the write speed. It will reset every bit on the flash to zeros. Just got the email a few days ago on a new release too.ДЄs for wiping the SSD, use the secure erase. It is one of the USBs I carry with me at all times.

I pay the annual sub, for they are always updating drivers for that one off motherboard or raid card drivers that you need when going to a customer / site, and you need to wipe the meta data off a drive and or clone some odd ball. I've used Parted Magic secure erase for so many years, I can't even count.
