![]() ![]() I have an internal hard drive of 2TB and it has system files, programs i use, downloads etc.basically information that i don't really care about much. I have an external hard drive of 1TB which is filled with information that i care about such as pictures, documents, videos, movies, and other important stuff sometimes a program, a game or a whole software project with lots of files that are connected. Basically information that i want to have while im alive. I bought a new external hard drive of 2TB. ![]() I want my 2 external hard drives to work together. So for example when i put some new data on one of them i want it synced to the other one too, aswell as when i remove something from one of them i want it removed on the other one too. I would also take one of them with me to the vacation or something work-related and when i come back after few days and have it plugged in again to my PC i want the data to synchronize to the external hard drive that i didn't take with me. So should I use RAID 1 or synchronization software (for example Synctoy) I don't want something like a backup, rather them both to work as a one thing. Well.making them "work as a one thing" would be a RAID 1. ![]() However.working as one also means any 'problem' that happens on one also happens on the other. You, the user, and the OS, sees but one volume. Or one file.Īccidental deletion, corruption, virus, ransomware.happens to at the same time. 2 FreeFileSync: This option from our roster of programs like GoodSync claims to be capable of optimizing your productivity and run-time performance and is quick and reliable. The only "protection" is against physical drive fail. This is all secondary data? Not the OS drive? RAID 1 does nothing for the far more common forms of data loss. Then maybe SyncToy, SyncBackFree, or FreeFileSync would work. It is not "instant", but whatever schedule you want. Presumably you'd be connecting this to a different PC when on vacation? Copy over new or changed stuff to the drive.Īpplications and programs are problematic in this, though. ![]()
