Samsung 840 Pro 256GB RAID0 SSD Review @ RWLabs
 

Having already served up a 128GB 840 Pro RAID 0 review we know that the fastest MLC based two drive array you can buy today is a Samsung 840 Pro array. Today we have for your viewing pleasure a larger 256GB 840 Pro two drive array. The 256GB 840 Pro is slightly faster than a 128GB 840 Pro and ever so slightly slower than the 512GB 840 Pro (which as you will see very soon in an up-coming review is the holy grail of MLC based drives)..
