FAQ:

Question: Is this all i need for a hardrive? Cable wise?

Answer: Depends. Is it an internal hard drive or external? These cables are for internal mounted SATA hard drives & SSD's (Solid State Drives). If your drive is internal, you will also need to power the drive from the power supply (PSU), so make sure you have an extra hard drive power cable coming from your PSU; it can be either the old style bigger 4 wire kind or the newer SATA power connector, unless your hard drive only has the new power supply connector (it looks like the end of these connectors, except it is a little wider). Smaller 2.5" drives (laptop size drives) usually only have the SATA type power connector; and the older 4 pin connectors are probably being phased out, though they are not extinct yet. These cables work for SATA I, II & III; the difference between I, II, & III is speed: I maxes at 1.5 Gb/s. II at 3Gb/s, III at 6Gb/s; both the HD and the motherboard SATA types will be rated at one of these three speeds. It is best to match speeds, but not absolutely necessary; mismatched speeds will work (they just won't be as efficient - e.g. hooking a SATA III drive to a SATA II mobo slot will work, but the potential max data transfer speed will be limited by the slower connector.. theoretically). 
Make sure your HD is SATA (I, II or III) - not eSATA (external SATA) USB, Firewire, TB (thunderbolt) or any of the newer formats like SATA express, PCI express or M.2 (if it is not an SSD, you can probably rule out the new formats). 
Check here for more info on drive types: https://rog.asus.com/articles/product-news/ssd-guide-pci-express-m-2-msata-and-sata-express-the-differences-explained/ ..or Google SATA, IDE (the older connector type), SATA express, mSATA, M.2, etc. 
The long answer: 
If your hard drive & motherboard were made in the last 5 - 7 years, and the drive is meant to be Internal (i.e. mounted inside the case - more importantly, hooked directly to the motherboard), then yes.. Well, you need to make sure you have an extra H.D. power connecter coming from your power supply (and your power supply needs to supply enough wattage to run everything in your system - a basic system with few internal peripherals can run on a P.S.U rated at 300 - 500 watts; if you have e.g. 6 hard drives, two high power graphics cards and an energy consuming CPU, you would need a P.S.U. rated higher - 650 - 1000 watts). 

There are also new SATA express PCI express and NVE M.2 Solid State Drives that mount directly in a slot on a motherboard - the PCI express and M.2 types don't usually need an extra power source but the motherboard has to have that kind of slot. It's a little like a PCIex1 slot, but not exactly. If you have a solid state drive and it looks a bit like a memory strip or a small video card, then it is some form of PCI express or M.2. If it looks like a laptop or desktop drive, it is most likely SATA, unless it is over 5 - 7 years old.. then it could be IDE (the older type that has a long data connector with a bunch of pins).

Question: What AWG are these cables?

Answer: They are marked with 26 AWG
