I am looking to get ether 2x 128gb ssd's or 4x 64gb ssd's to make a raid 0 array in my computer.
I currently got in this build 64 gb ram and 3 way 770 sli. My storage is over NAS i just need ssd's to make the boot faster and make applications load faster. Looking at 2 Samsung 840 Pro's but I do not know about 64gb ssd's. What is faster, better for life, and fits $250 budget? Keep in mind that speed is equal priority to lifetime. Also would the IOPS read and write be doubled in a 2 way raid?

The 840 Pro ssd's spec's are:
Sustained Sequential Read: 530 MB/s
Sustained Sequential Write: 390MBps
4KB Random Read: Up to 97,000 IOPS
4KB Random Write: Up to 90,000 IOPS
MTBF: 1,500,000 hours

The raid method isn't worth it. It doesn't help at all, and you lose TRIM which hurts your performance. Without TRIM, your performance would drop below single drive performance within a few days. If the drive pair is half full or more, it would be even faster. I know because I tried it with a pair of 120GB 840 EVOs. (Those EVOs are now the OS drives for my servers.)

As far as the Samsung 840 Pro goes, you're better off with a single 256GB for less money, plus you can use the Magician software to add an extra caching routine. That helps a LOT. I have an 840 Pro with that software, and the performance numbers are better than a raid pair.

Also, RAID 0 cuts your reliability in half. Granted, with 840 pros, that's still pretty good, and far better than any mechanical drive, but it still isn't a great idea.

The performance difference between the 840 Pro and the 840 EVO at comparable capacities is very noticeable, especially on an OS drive. The write speeds are so much faster on the Pro. If you notice, I have both a 256GB 840 Pro and a 250GB 840 EVO. The EVO is good for storing games, as long as the writes aren't too much and the duties are mostly read, bit the 840 Pro is a far superior drive. Plus, the price difference these days isn't too bad. the extra $50 is worth it.

1. Based on the initial information you provided it appears as if you are a hardcore gamer. Is that correct?

2. What issues have you experienced with the Samsung 840 EVO lifespan? What is your concern?

Slapping myself upside my head. I should have caught it when I saw 64GB of memory listed. Is it an LGA 2011 X79 motherboard or a server motherboard?

If you have a real need for speed, then I might have an alternate solution for you that will cost nothing or only a few dollars.

Configure a portion of your memory as a RAMDISK - hundreds of thousands of IOPS and data transfer rates of up to 16GB (not Gb) per second. Use it as a scratch disk for your work.

If you are not familiar with ramdisks, here is a link to a short video clip over at newegg that will give some idea what you can do:
