Mechanical drives vs SSDs in RAID 0 configuration

As i know the SSD had almost saturate the sata3 bandwidth so in raid it will bottle necked.....

Also some raid can disable TRIM... (without TRIM the ssd will gone bad or had performance drop over time...)

purchasing one bigger/better ssd is better than 2 in raid....

Hello rdc85,

Thank you very much for your response. I have also received a response on another forum that I thought may interest you See post by crjdriver. It appears to be possible with a motherboard that has the Z77 chipset (and others may exist that work) which supports both RAID and TRIM.

Check out these very impressive speed results - RAID 0 SSD Benchmark

Benchmarks are fun to look at all right, but in real life, there is practically nothing the average person will be doing that could saturate the bandwidth of a single SSD. One of the things that makes an SSD so fast is the quick access time, that is something that is instantly noticeable but even the throughput on a decent make of SSD is simply mind boggling if you have never had the pleasure of using one. When you install a program, it simply blazes through the install in seconds.
I have also been a person who favored RAID 0 configurations in the past. With the cost coming down to reasonable levels for an SSD, and having used an SSD in my system now for over a year, I have completely forgotten about RAID, its an outdated novelty more than anything in my opinion.

I'm cannot assume u had z77 (since only newest intel chip can do RAID and TRIM, it more safe to assume to not recommend to use raid with ssd). Hehe... 

Hi Guys,

I have been running Windows 7 on a Corsair Force 3 SSD for about a year now - the speeds are very impressive, particularly boot up times!

At the moment I am slowly but surely acquiring the parts for what I consider to be a "dream machine" - this computer will feature Viper RAM, and a FSB of 2133 MHz. The next bottle neck down from the FSB is definitely the hard drives so I am trying to get a sense of what having SSD in RAID 0 will achieve.

I have also read that a VelociRaptor (mechanical drive) is a good way to go. Currently I am stuck between installing one SSD for the OS, and a VelociRaptor for DATA, or alternatively installing 2 x SSD in RAID 0 (for both the OS & Data - then performing regular backups [probably nightly]).

The most intensive work that I have done is on PhotoShop files that are about 1 Gigabyte in size, and improved write speeds will serve me more than improved read speeds. I did notice that SSD in RAID 0 improves read speeds dramatically, but the same cannot be said for write speeds.

Any advice, or personal opinions are welcome.

Kind Regards,

Davo

No, I do not have a z77. You don't need one to be completely blown away by what a SSD can do for performance. If you have never used one, just buy one, install it, and prepare to be completely amazed. You will forget about RAID because a single SSD is so fast, you will understand why I say RAID is an antiquated thing, you simply don't need it anymore.
