How can I make my SSD faster and more secure?

Jake from Dallas, TX

Jake swapped out his smaller SSD with a larger one on his computer. Leo says that Jake could just keep that drive as his software only drive and then use the larger drive for data. He could even combine multiple drives into a RAID for redundancy. He should keep in mind that using RAID 0 may be fast, but it's also less reliable because if one drive fails, it all fails. RAID 1 would give him data security by making multiple copies of the same data. RAID 5 is what is common now, and that offers the best of both worlds.

Alan from Honolulu, HI

Alan set up his RAID backup and his drive failed. Then a second failed. And now he lost everything. Alan paid a drive backup company to rebuild his RAID and get the data and he got it all back. But it cost him $11,000 to do. OUCH. Lesson painfully learned.
Leo says that while a backup RAID is a good idea, it's only one link in the backup chain. You really need to adopt a 3-2-1 backup strategy, three backups, on two different media, one off site.

Stan from San Francisco, CA

Stan wants to clear off his DVR with a 2 Bay RAID to save his programs. But his beef is that there isn't a lot of documentation. Leo says don't worry about all that. Just use the PC settings. You can also use a DROBO, which allows you to hot swap drives if they fail so you don't have to stop it from running. But two drives isn't best because it's mirroring and you will only get half the capacity since they're identical. Leo prefers RAID 5 with three drives which gives you 2/3 storage 1/3 redundancy. It's robust. Companies that make eSata RAID 5 include Drobo.

How can I recover data from a failed RAID?

Episode 1060

Eric from Corona, CA

Eric has a RAID 5 server that has had two drives fail and he needs some data recovery services. Leo says he doesn't know if data recovery is even possible if more than one disc dies. If a large enough chunk of data was lost, there's just no way to get it back. But it will largely depend on how it failed. A controller could've gone bad, and that could be an easy fix and the data could still be there. This is why one backup isn't much of a backup.

Tony from Los Angeles, CA

Tony works for a security firm and he wants to mirror the data of a hard drive onto a RAID. Leo says the first thing Tony should do is clone the drive since it's a very important drive to his job. Drive's will eventually die, so it's vital for Tony, or anyone for that matter, to clone the drive to back it up. Hard drives usually come with utilities for this purpose. EaseUS has a great imaging utility for that. Once that's done, save the original drive in a safe place and then use the cloned drive moving forward.
