Green are fine, but not the best for an OS drive, go blue or black for that.
I have noticed that Blue has 8MB cache and Black has 32MB. I recently bought 2 Blue drives for some old systems and noticed that both had 8MB cache.
Maybe Green has 16MB of cache.
I would opt for the Black series drives myself.
Edit: I just checked and Cache isn't related to series.
Blue and Green are 3 year warranties while Black are 5.
Well, the Greens use a 5400 RPM spindle speed vs. the 7200 of the Blacks. I'm not sure about the Blues though
NO! The Green uses 'Intellipower', which is a marketing gimmick which means that it spins at 5200RPM all the time (not 5400).
Caviar blue = 5400RPM
Caviar Black = 7200RPM

If you realize that the number one bottleneck in a computer system is the secondary storage devices (hard drives, optical, etc), you will see that the Caviar Black is the best way to go, even for the purpose of a storage drive. Imagine how much longer a backup of that drive would take if it were a Green vs a Black, not to mention the I/O benefit you gain if you want to do more than one thing at once with the drive.

Correct me if I'm wrong Hard:
Black = speed
Blue = budget
Green = storage

well this is highly inaccurate......the blues are 7200rpm also
i own a 320Gb AAKS myself, depending on the benchmark and status of the drive i have seen it run 100Mb/sec
Correct me if I'm wrong Hard:
SSD = OS
Black = meh
Blue = meh
Green = storage
I use a green for my O.S. and works great.
If you see the sequential transfer speed on the outer tracks of that WD3200AAKS drive as around 110 MB/s, you have the single-platter version of that drive. But if your particular drive benches at only 70-ish MB/s, you have the older two-platter version. And there were a few very early 320GB WD Blues that were three-platter designs; they top out at around 65 MB/s.
Homer, I tend to agree but the more reviews/articles I read on SSD, the more nervous I get. If the OS writes alot, the SSD gets slower (HDD does too) at first but after a few months or a yr, the SSD will fail permanently. Bits get stuck. At least a HDD can be rewritten to a known clean state (complete wipe/reinstall). What kind of warranty do you typically get on an SSD?
So I just RMA'd by 640gb WD Black drive and they sent me a 1tb blue drive.
Model number WD10EALS-002BA0 and this blue drive has a 32mb cache.
I don't really need that extra space for my desktop so I don't necessarily care that it's bigger. Should I keep it or complain?

Wherever you are reading this FUD about SSDs, find somewhere else to "research".
Anand's site and Toms hardware. But maybe I was reading year-old articles. You tell me - are SSDs really reliable? I know the enterprise (expensive) ones are better. They use SLC flash parts. But the consumer grade use MLC which are more prone to have stuck bits from being rewritten too many times. Flash MLC have write endurance of only 5k program/erase cycles whereas SLC spec 100k cycles. Check out Numonyx/Micron specs. The MLC flash parts are dramatically worse. 5000 program/erase cycles, come on, that aint a whole lot. But it's not just the Anand/Tom websites -- check out the reviews from users on newegg.
You might want to loosen the tin-foil hat.
SSDs are a lot more reliable than regular mechanical drives. You could move a shit-ton of data every day for 5 years and still not hit the read/write cycle limits. I'm talking 100GB of data, a day (the average user probably moves 2-5GB, a power user moving 20-30 maybe). The point is that other drive components will fail before you hit the read/write cycle limit. And yes, I'm talking about the "lesser" consumer MLC stuff. Maybe you're thinking of the first generation stuff? Because Tom's and Anand articles will tell you the same thing that I'm telling you.
As Surly73 said, wherever you're getting your info from, they're either very old articles on very old SSDs, or very one-sided. Have you actually used a modern SSD before?
No, I havent used an SSD before - that's why I'm asking. I was ready to buy one and started to read up, got cold feet. But you're giving me some confidence. I want to get a small capacity to install OS/apps and keep my WD green hdd for data storage. I was looking at Kingston SSDs but the 8G got marginal reviews while the 16G model got good reviews. Does the 8G drive use older flash chips?
