That’s one reason why Apple includes a T2 security chip on its new Macs. In a perfect world, hardware-accelerated encryption is definitely better. If you need encryption, you’re better off using BitLocker’s software-based encryption so you don’t have to trust your SSD’s security. Unfortunately, it seems many SSD manufacturers cannot be trusted to implement this properly. So, if an SSD had solid hardware-based encryption technology, relying on that SSD would result in improved performance. When available, hardware-based encryption can be faster than software-based encryption.

RELATED: How to Encrypt Your Windows System Drive With VeraCrypt You won’t have these issues if you stick with BitLocker, so we recommend using BitLocker and disabling hardware encryption. We recommend having rescue media on hand, just in case.

Warning: Some big Windows 10 updates have caused issues with VeraCrypt in the past. VeraCrypt doesn’t ever rely on SSDs the do the encryption work-VeraCrypt always handles the encryption itself. You don’t have to pay $100 for encryption.

Unlike BitLocker, VeraCrypt is also available to Windows 10 Home and Windows 7 Home users. Group Policy is only available on Windows 10 Professional-but then, so is the standard version of BitLocker. If you’re using BitLocker encryption on an SSD, you can tell BitLocker to avoid using hardware-based encryption and use software-based encryption instead.

How to Make BitLocker Use Software Encryption In other words, this is a new feature in Windows 10, so Windows 7 systems won’t have the same problem. Do you trust that the manufacturer of the drive in your laptop did a good job? Do you even know what company made your laptop’s internal SSD? Did your laptop manufacturer think about this before it selected a hard drive vendor?īitLocker on Windows 7 does not support “offloading encryption to encrypted hard drives,” as Microsoft’s documentation puts it. And, as researchers have found, SSD manufacturers are having some serious trouble implementing encryption properly.Įven if you opt to encrypt your laptop’s hard drive with BitLocker, you’re now relying on whatever company made the SSD in your laptop. BitLocker just trusts the SSD to encrypt your files, abandoning all responsibility. If your computer has a solid-state drive that says it can handle hardware encryption, BitLocker doesn’t do anything at all. And BitLocker encrypts the files before storing them on the SSD, right? This wouldn’t normally matter-after all, who uses the hardware encryption on an SSD? Windows users would use BitLocker instead. hSlPCMyHsiīitLocker Trusts SSDs, But SSDs Aren’t Doing Their Jobs But don’t worry, customers, you can turn it off! Everything will be fine. The encrypted SSD has a master password that’s set to “”. Yes, that’s right-it has a master password set to nothing, and that empty password gives access to the encryption key that encrypts your files. Even if you don’t have any of these specific drives, you should be concerned.įor example, the Crucial MX300 includes an empty master password by default. The researchers tested drives from Crucial and Samsung, but we definitely wouldn’t be surprised if other manufacturers had major issues. They reverse engineered the firmwares of many solid-state drives and found a variety of issues with the “hardware encryption” found in many SSDs. That’s the conclusion from a new paper by researchers at Radbound University. Instead, Windows 10 may be relying on your SSD to do it, and your SSD’s encryption may be easily broken. Many SSDs Don’t Implement Encryption ProperlyĮven if you enable BitLocker encryption on a system, Windows 10 may not actually be encrypting your data. Update: Nearly a year later, BitLocker no longer trusts your SSD, so you can trust it once again. It includes a command you can use to check whether you’re using hardware or software encryption.
Update: Microsoft has issued a security advisory about this problem. But researchers have found that many SSDs are doing a terrible job, which means BitLocker isn’t providing secure encryption. Some SSDs advertise support for “hardware encryption.” If you enable BitLocker on Windows, Microsoft trusts your SSD and doesn’t do anything.
