The only definite, absolute, and fool proof way to destroy data on an SSD (or an HDD) is to reformat the device. The Only Way to Delete Data from SSD’s with Certainty Hence a shadow of the information always remained on the SSD. Read how a bunch of engineers from University of California only achieved 25% to 96% success when they tried to delete records. The information may eventually be overwritten, but again it may not.

They are forever rearranging files to optimize storage. The waters are muddier when it comes to deleting files on SSD’s. Since the storage space is random, this can take a while. The actual data remains intact until we overwrite that spot on the drive. When we delete a file on a hard drive disc, the master file index simply tags it as belonging in the recycle bin, not the folder. What Deleting Files on a Solid Data Drive AchievesĪgain, we have to thank the engineers at MUD for simplifying things for us. This begs the question, what happens if we want to get rid of the old file.

Thus, if we want to write a new version of a document to an SSD, it creates an entirely new version on another page. This contrasts sharply with hard disk drives that can write data to any available location. Solid state drives can only write data to empty pages in a block. These pages are in turn bunched in blocks. These cells are arranged in sections called pages. Instead, it stores the information permanently in a grid of high-speed electric cells. How Solid State Drives Process Data and Delete ItĪn SSD’s flash memory does not clear when it shuts down, unlike a HHD. Again, we have to delve into technology to understand how this happens. SSD technology does these downloads faster than hard drives by as much as a factor of ten. When we decide to access these, it takes a little longer to transfer them from disc to memory. The actual hard disc: This functions as a ‘permanent’ library of programs, documents, audio files and so on. Computers use this to store active processes and programs so they can get to these fast. The middle memory ground we call random access memory, or RAM for short. Engineers keep the electrical pathways short so access to data is virtually immediate.Ģ. The uppermost cache, where the machine does its active work like calculations and procedures. Computer architecture contains three levels:ġ. We find them a great place to look when we need to clear the muddy waters of technology beyond our normal lens. We acknowledge contributions from MUD before we continue. To understand how this memory functions, we have to understand computer architecture, and more specifically computer memory.

SSD’s, on the other hand, are disc drives with arrays of semiconductor memory using integrated circuits. HHD’s have a spinning disc inside them, and an actuator read-write arm to transfer the data. The similarity ends there because the hardware inside them is different. They may also fall into malicious hands if we are not careful.

They are compatible with computing devices, and being portable we can ‘carry our business in a briefcase’ everywhere we go. The similarity ends there because the hardware inside them is different.External hard disc drives (HHD’s) and solid state drives (SSD’s) are both useful places to store large amounts of data, or to back up files.
