128gb ssd raid worth it??

[markdude100]

Ive had my PC for about 4 months now and Ive wanted more ssd space. Currently I am using a samsung 128gb 840 pro and i was wondering if i should by a second one and run a raid 0 setup. Need help asap!

Depend on how are you going to build Raid. If software one, raid0 on SSD won't give you much benefits, better buy bigger drive 256Gb or more.

Dr-Kiev's right, typically you won't see as much improvement with SSD as you do with HDD for Raid-0, IIRC it is because of controller saturation. A single SSD with a bunch of HDD in Raid-0 works pretty nicely though

I didn't do it for speed, just space on a single "drive". I had a pair of 120GB SSD's that made a very nice 240.

The only downside is the fear of drive failure - if one goes, the data for both is gone. (Not as if SSD's fail very often!)

In this case, better create span (JBOD) , same volume size, and no so much fear if one drive crash, like in Raid0

I did this for a while also, a couple of Crucial M4's for the OS and a couple of Plextor M3's for all of my work data and storage - backed up at least nightly to a regular HDD.

No problems for me with raid0. Wish I had kept that setup actually.

Raid0 always more dangerous than others , this is main disadvantage.

I agree with Dr Kiev. I've run both configurations, and creating a span is so much safer.

I absolutely agree with you, that is why I had a very regimented backup program in place.

Backed up the OS drives (C) daily to a HDD, the data drives (D) at least three times through the day (to a third set of raid0 SSD's) so I would never loose more than just a couple of hours work. Also backed up (D) to a HDD at the end of the work day every day.

Probably overkill, but after loosing several days worth of work one time I didn't want to take any chances. Learned a hard lesson.

Definitively sounds a bit overkill but if the data is important to what you do then it isnt overkill.

Since maybe 2003, we'd had some five RAID0 arrays running on different machines here 24/7 without fail until we chose to decommission this or that system. I had also set up my sis-in-law's computer some years ago with a two-drive RAID0. I still suspect that she entered the controller's BIOS and started fiddling with it, because it went south. But here in this house, I keep an eye on all the machines and we never had any trouble.

We still have one system with a RAID0 created in 2008 with WD Caviar Black drives. No problem.

You'd figure the risk would be lower with the expected lifespan of SSDs. But like someone said, with SATA-III SSDs like the Samsung EVOs, you're not likely to notice the difference in speed for reasons already cited.

Maybe JBOD is the way to go -- if you don't want to simply buy a larger SSD.

I had a pair of Samsung 830 256GBs in RAID 0. No real difference between that and a single one. I wouldn't bother with it.
