I am considering making a LAN file/print server from one of my computers. It has the following specs:
Gigabyte GA-P35-DS3L (NO hardware raid built-in)
Windows 7 Professional 64-bit
160gb hdd (OS+data)

It will be used by four family members using different computers and operating systems (vista, 7, mac, linux). The server will mostly hold pictures and videos (approx 100gb).

Is it a good idea to get two SSD drives and put them in RAID 1? I don't care about speed, just reliability. I guess SSDs are more energy efficient and possibly more reliable than HDDs.
SSD1: SanDisk Ultra SDSSDH-120G-G25 2.5" 120GB SATA II Internal Solid State Drive (SSD)
SSD2: Mushkin Enhanced Callisto Deluxe MKNSSDCL120GB-DX 2.5" 120GB SATA II MLC Internal Solid State Drive (SSD)

It's fine but I would not do it.

Then make daily backups to a drive that is preferably offline most of the time. Your raid1 of SSDs does not remove you from needing that anyways. Since no level of raid is a backup.
 
Rather make daily backups and run them in raid0 :shrug:


As stated running RAID1 does not stop you from having to do backups anyway...

We currently do, with a portable hard drive that gets tossed around and frequently transported. Maybe the RAID thing was a little too overprotective, I might just use a single drive. Aren't internal drives essentially "offline most of the time" if they are not the primary OS drive? And even if they are the OS drive, don't they turn off after X minutes of inactivity? Isn't all of this "offline" business irrelevant within the context of SSD drives because they don't spin?

I was thinking it is underprotective and costly.

Remember that raid is not a substitute for a backup. RAID does not protect against viruses, accidental or deliberate deletion, power surges, theft, natural disasters ... Where an offline (possibly offsite) backup(s) can and do protect against these things. RAID is more for uptime than for reliability.
 
So you're saying the best thing we can do, besides offsite/mirrored backup, is what we are already doing?

+1 to this.

In the end, an offsite/offline backup must still be made to ensure the safety of the data.
RAID1 just adds up-time insurance, that's it.
 
when we say offline we usually mean the drive is not powered one and stored in a safe location.
