Here are the main methods that are used at present: Run shred and hope for the best Ideally, I would recommend using a combination of methods for security. The same issues with SSD storage can affect this cache of data. Hybrid drives offer some speed advantages: By leveraging a small amount of SSD storage, these drives save data to SSD first, then write it at slower speeds to the actual magnetic platters. There could be hundreds of bytes, or even kilobytes or megabytes, of data that the shred doesn’t reach.Įven some “traditional” storage can run into such issues these days. Complicated systems introduce issuesīecause SSDs manage which blocks of storage they write to, a simple shred won’t do. However, this leads to some issues as well. This is less of an issue with modern drives thanks to wear leveling built into the firmware of the drives. SSDs have issues with speed if the drives are too full, and have a limited lifespan-only a certain number of write operations can be achieved. Solid state drives, or SSDs, are faster, less prone to errors from physical impact, and generally more sought after. Nowadays, most servers have switched away from storing data on rotating metal or glass platters. Only the most paranoid might destroy it physically. ![]() A cautious one might run a demagnetizing wand over the drive. ![]()
