I am using a SSD right now as primary. I plan on attaching a 1TD HDD as secondary or "slave" drive for downloaded files, backup, and game storage. I may or may not use RAID, but I most likely will in the future. I was looking online and some that are on sale are Western Digital WD. There are different series such as black, red, blue, and green. I was wondering if I should go for black or is red enough? All are SATA3 interface with 64mb cache. The difference between black and red is only $10.

The red for enterprise and server drives..they should have the lowest failure rate...green...going o be the highest.

Best solution

Well, on WD drives they are manufactured with different purposes in mind. Blue drives are the inexpensive line of "normal" desktop drives, you will find a ton of computer manufacturers that use these drives in the computers they make (HP, Dell, etc...). Black drives are the performance, or upgraded blue drives. These drives are made with better components, are faster and will last longer than WD's blue drives. Green are low power, slow, and should not be used for RAID due to their intellisense (disk spin down) which can cause an array with green drive(s) to tear or separate. Green are good when power is an issue or the device it is in will not be used often. Lastly, the red drives are intended for RAID arrays in external storage (NAS boxes, or a storage server) These are devices that never turn off, and do not need high performance out of a single drive (think of a marathon runner).

Can they be used for other things? Certainly. Personal opinion would be if this is a normal desktop, reach for the Black drives, high performance and good life expectancy. If you are building a NAS box or file server, reach for the Red drives.

thanks for the explanations. yea i would longer lifetime on my HDD. I guess green is out of the question. I have a decent PSU so power isn't a problem and I don't plan on building NAS box or any kind of servers. I guess the black HDD is good. What do u guys use? just wondering

I've owned 6-8 Blues, 1 Green, and 5-6 Blacks. The Green was an experiment that worked, but not as well as I would like. I haven't purchased any Reds yet, but I need to expand my Windows Home Server, and those will be the drives I will be reaching for.

All in all, I think of the Blacks as a great base to build a computer around.

how much longer do red drives typically last compared to the others?
