MVMe vs raid 0

[littlepigboy5]

After learning about the new MVMe technology, and how much praise it has been recieving, I am curious why everybody is so excited.  I have seen the read, and the writes, but I have also seen the cost.  Wouldn't it be much more cost efficient, and if done correctly, faster to just stick 4 ssds in raid 0.  It would cost less to have 4 ssds in raid 0that adds up to 480gb than buying the 480gb mvme drive.  I know that the sata bus will be the bottleneck in the future, and we have almost reached that point, but looking at where we are now, I see no reason for the MVMe drives to be public.  Why don't they, they being intel or whoever makes MVMe drives i guess, work on the tech a bit more, make it more cost effective and release them when we have reached the 6Gbps bottleneck of Sata III?

NVMe? 4 ssds in raid 0 has a much higher chance of failing and you losing all your data and IOPs doesnt scale as well as sequential in raid 0

NVMe. Because RAID0 is dumb, and very unsafe. This technology is new so it's going to cost a lot for a while, but once it's aged a bit it'll be as cheap if not cheaper than current SSD's.

NVMe is not a physical interface, it's an interface protocol like AHCI before it. It's not how the SSD is connected, just how it utilizes that connection. The point is that an SSD on any given link would be faster with NVMe than with AHCI (let alone legacy IDE mode).

 

RAID0 just means you're combining multiple drives with striping. It doesn't change the interface protocol or the physical interface, it just adds them together.

 

Edit: Also, @ this...

... we have reached the bottleneck of SATA3. Long ago.

RAID0 is neither dumb or 'very unsafe'.

 

It gives you increased performance and how often do you find things failing in todays technology? I have had my SSD's in RAID0 for the best part of 2 years now and they are perfect. I just choose not to store any important data on them.

 

 But I agree NVMe > RAID0 sata any day. You loose the sata bottleneck and well as the serial "one at a time" communication that comes with SATA. But for me the most important factor in why NVMe is so much better is not just the increased speeds (2Gb/s+) but the IOPs increase is massive.

 

Also with using SATA to RAID0 you will very quickly hit the bottleneck of SATA and if you are using SSD's you will hit this limit in a 2 SSD array. NVMe removes this bottleneck as its running on a PCIe based connection (with MUCH higher bandwidth than SATA).

Compared to anything else, RAID0 is dumb. I mean just one of those drives dies and you're screwed. But if you have no other option it's fine.

The comparison is kind of useless anyway. You could just as well run NVMe drives in RAID0.
