Do CMD-Q when the Mac reboots and the set up process first starts.Īnd now, phew!, you’re ready to sell your Mac.

“ How to Securely Erase a Mac SSD.” In brief: If someone were to examine the unused space on the newly erased drive with a digital forensic tool, all that would be seen is encrypted nonsense.įor an Mac’s boot drive, Peter Cohen explains the process nicely. (This what happens when you do a master reset on your iOS device.) Then the SSD is erased and formatted as usual. This renders the information stored on the drive unreadable. Cryptographic Eraseīasically, a cryptographic erase means encrypting the drive, then throwing a way the encryption key. Selling your SSD Mac? Cryptographic erasure is a great option. And that’s called a “cryptographic erase.”

The very best description of the difficulty conventional tools have in completely erasing an SSD comes from the Electronic Frontier Foundation (EFF.) The article is: “ How to: Delete Your Data Securely on Mac OS X.” Skip to the very last major section labeled: “Secure Deletion on Solid-state Disks (SSDs), USB Flash Drives, and SD Cards.” It’s a long paragraph, but the language is simple as it describes how SSD “ wear leveling” undermines the best efforts of erasure tools to completely overwrite SSD data.Īs a result of how SSDs write data, the best practice today involves going one step beyond the simple process of using Apple’s Disk Utility “standard erase” for an SSD. That last throw-away comment, “for more security,” suggests that there’s a little more to cover, so that’s the next topic. For more security, consider turning on FileVault encryption when you start using your SSD drive. These options are not needed for an SSD drive because a standard erase makes it difficult to recover data from an SSD. With an SSD drive, Secure Erase and Erasing Free Space are not available in Disk Utility.

You’ll also want to read “ OS X: About Disk Utility‘s erase free space feature.” A note at the end starts to get to the heart of the matter. However, that Apple article skips over the nuance of completely erasing an SSD. Our zip test uses a 5GB game folder and the 30GB transfer is a packed Steam installation folder.Recovery options (CMD-R). This would explain the difference in real-world performance between the different capacity drives, despite their comparable synthetic benchmarks. If it exceeds that limit, such as in our real-world tests, then the drive will revert to a slower 3-bit MLC speed.

If an operation doesn't use the full extent of the pseudo-SLC, and is given time to idle and flush the cache in between tasks, the drive will run at full speed. There are different amounts of NAND given over to emulating SLC for each capacity of drive if it follows the Samsung 840 EVO range the 250GB will effectively utilise 3GB of SLC and the 500GB doubles that to 6GB. SLC is quicker than the 3-bit MLC used throughout the rest of the drive and acts almost like a speedier form of cache. TurboWrite apportions some of the drive's capacity to be used as a form of pseudo single level cell (SLC) NAND. That might well be down to the TurboWrite tech Samsung uses to speed up its 3-bit MLC drives. Our zip compression and folder transfer tests show the 500GB drive comfortably ahead. The real-world scores though are a little slower for the smaller drive. In fact, the slight difference between the synthetic numbers of the 250GB and 500GB drives could arguably be put down to standard variances in testing. That means the performance of the cheaper 250GB version is almost identical.

These are the results for the 500GB version of the Samsung 850 EVO, but the introduction of a new Samsung controller - the MGX - for the capacities of 500GB and below has been primarily tuned to provide consistent performance across the range. Those are decent improvements and mean that in the real-world we saw our 30GB Steam folder transfer test resolve twenty-two seconds quicker than the Samsung 840 EVO.
