SSD RAID Question

post #1 of 8
Thread Starter 
If I bought 2x 250gb Samsung 840 EVOs for my game library, which raid config should I put them in? My motherboard supports RAID 0, 1, 5 and 10.

RAID 5 requires a minimum of 3 drives and RAID 1+0 requires a minimum of 4 so they're both out.

RAID 0 will result in faster speeds but also halve your reliability. RAID 1 will halve your capacity but double your reliability.

To be honest, I wouldn't RAID them. Just use them separately or if your board supports JBOD then use that.

raid 0 they are ssd, faulure rates are way low and you would benifit mostly from speed and drive size.

You should NOT raid them..

If you want details, do some research on the following topics:

- TRIM support for RAID (it's mostly nonexistant)
- SSD firmware issues when used with RAID
- Random, drastic, unexplainable performance drops when SSD is used in RAID
- The actual performance gain you get with SSD and RAID (it sucks)

tl;dr
If you RAID your SSDs, you'll get a lot of headaches, and very little performance gain.

no trim support is old news with ssd most new work

and im pretty sure you made the rest up off of a few people complaining.

lol, thanks for making me laugh


yes, you need raid0

z77 has trim for raid, i don´t know other chipsets

i have 2 crucial m4 raid 0 since 2012, they are perfect always, never lost my array, with trim, great perf (near 1000mb/s reads)

Depends on usage. That said, I doubt the game library would benefit from RAID-0 so I'd skip it if I were in the OP's shoes.

I heard from people who work at datacenters that SSDs are a pain in the ass for RAID arrays.

They don't use a motherboard's built in RAID. They use dedicated enterprise hardware to set up RAID.

And also, you're not going to get any appreciable performance increase. Even if you happen to get double the read/write throughput, unless you're running very specific applications, with a single SSD your bottleneck is probably somewhere else already.

I would also be very uncomfortable with using a motherboard's RAID, because enterprise RAID hardware is made with data integrity as a high priority, and if your RAID card burns out you can replace it with many similar models and not lose your array. If your Z77 chipset burns out, I'm not sure if different chipsets will support the array made by your Z77. Also if you have a power outage or something, I wouldn't trust the motherboard's RAID to handle it properly. All enterprise RAID hardware supports battery backup.

So give that, and the fact that 500 MB/s is more sufficient for anything you're doing. I'd skip RAIDing it.
