Single 512GB 830 or 2 x 256GB in RAID 0 ??

Definitely get the single drive. Outside benchmarks, RAID0 with SSDs does not have as much of a noticeable impact as in HDDs. Plus, as others have mentioned, many SSDs lose their trim support when RAID0 is used.

IMO I wouldn't both with Raid once you have an SSD, fast enough

Don't RAID it. You get increased resilience and longevity with a single larger drive, and the performance increase with RAID won't be noticeable.

edit: oh, old thread. Thank you Mr reviver.

Thanks all the same Kal I took your advice
