Worth the extra 7 bucks for extra HD cache?​​​​​​​

SATA 3gbps is enough for RAID 0, though it depends on your motherboard. Mine supports RAID on 6 out of 8 SATA ports.

CPU: i7-2600K 4751MHz 1.44V (software) --> 1.47V at the back of the socket Motherboard: Asrock Z77 Extreme4 (BCLK: 103.3MHz) CPU Cooler: Noctua NH-D15 RAM: Adata XPG 2x8GB DDR3 (XMP: 2133MHz 10-11-11-30 CR2, custom: 2203MHz 10-11-10-26 CR1 tRFC:230 tREFI:14000) GPU: Asus GTX 1070 Dual (Super Jetstream vbios, +70(2025-2088MHz)/+400(8.8Gbps)) SSD: Samsung 840 Pro 256GB (main boot drive), Transcend SSD370 128GB PSU: Seasonic X-660 80+ Gold Case: Antec P110 Silent, 5 intakes 1 exhaust Monitor: AOC G2460PF 1080p 144Hz (150Hz max w/ DP, 121Hz max w/ HDMI) TN panel Keyboard: Logitech G610 Orion (Cherry MX Blue) with SteelSeries Apex M260 keycaps Mouse: BenQ Zowie FK1

Yes, I think an extra $7 is worth it for more cache, however in this case I would get the barracuda. You can look at the 4 tb barracuda that has 256mb of cache. :)

Worth the extra 7 bucks for extra 128 cache? SATA 3Gb/s it's not enough for raid 0 right?

RAID 0 speeds are the speeds of your slowest drive multipled by the number of drives in the array. Each SATA port/cable only needs to meet the speed of the single drive it is connected to. The total speed combination happens further up the chain.

 

I have an array of 12TB WD Golds, and they each max out at about 250MB/s at their fastest (they get slower with more data because they start on the largest outer track and work inwards. Smaller/shorter tracks read/write less data per revolution). SATAIII (6Gbps) can do about 550MB/s on the best SSDs, so even SATAII (3Gbps) is more than enough for practically any 7200RPM mechanical drive.

If you want good hardware recommendations, please tell us how you intend to use the hardware. There's rarely a single correct answer.
