Just curious-your headline says SSD512GB, but your bench test shows it's a Toshiba 128GB.
Which is it?
Just one question, booting and starting programs is alot faster with SSD but just how much more performance do you get when you are actualy using an already opened application? Do you see any speed benefit of the SSD when doing normal tasks (mail, internet, typing, itunes) with your mac?
generally everything will be much quicker and smoother. anything that needs to load data from the ssd does it much quicker (think browser cache) and so most applications benefit in some way from ssd's. games will have significantly quicker load times, photoshop will open large files much quicker, same for adobe reader and pdf's. also you can open many many things all at once (lots of pdf files for example) and they will open just as fast as if you opened only one (as opposed to an hdd that will take much longer to open many things at once). just a few examples.

Actually BlackZ was able to get a disk score of >400. https://forums.macrumors.com/posts/9858109/ I've been using mine for about 2 months now with no slowing down. Very happy with my C300.
After using GParted I managed to restore my SSDs to fresh state, boosting my Xbench and AJA Test score (Xbench was earlier around 180, AJA said 150MB read, 100MB Write)
These are new results:

What do you keep on the C300 SSD? Have you offloaded your application files like iTunes and iPhoto etc. to another drive or have you left them on the SSD?
This weekend I'm trying to figure out what to do about those 2 applications.
For example:
Mini 3,1 2.53 converting to 8GB RAM while converting to OWC 256 SSD and Momentus XT as second internal HD. Original drive is stock Apple 320GB HDD.
Have never opened a Mac before-so some apprehension.
1. Data Sizes--
a. OSX 10.6.4 4.79GB- a week ago.
b. Library 13GB-I don't even know what is in that is yet exactly.
c. xxmyusername on HD 131GB
d. Music 117GB-yes it's a ton of ripped CD's. I remember raw it was 104GB.
e. Pictures 6GB.
2. I'd love to get all the iTunes and iPhotos data on the XT where all our house computers can access both music and pictures from one location.
3. Also have a 8TB mirrored LaCie external (4TB useable) that I use for important data. With that size it should take me well into the future, but it already has about 300GB of video from iMovie.
4. Don't know if it was correct, but I just dragged the iTunes, iPhoto & iMovie icons into the LaCie. Checked to make sure the Imovie stuff was OK and then deleted it from the stock 320GB HDD so iMovie files are now blank when I open iMovie.
5. Guess I now must tell iMovie where data is stored?
6. Also just got the OWC Voyager so I can put data into a 2.5" drive for safe keeping in a bank vault. Yes I'm crazy, but have already lost all my data due to a hurricane in the past and am now trying to never again loose irreplaceable data!
Sorry that this got so long, but would like to hear from others' experiences along these lines since I am relatively new to moving Mac files around correctly. Just realized that maybe this is put somewhat on the wrong thread. If so, kindly point me there. Thanks.
Thanking anyone in advance who can offer their experiences/suggestions in these kinds of endeavors.
the numbers
these numbers make me wonder what i can expect from the 17" i7, 8gb ram with 128 SSD that is being delivered next week from apple. from reports the numbers don't look to bad at all.

I don't run dual drives like you're planning to. Everything is loaded on the SSD. I have the usual OSX, iWork, Office, Xcode, Parallels, and newly added SC2. Currently use about 84GB out of 255.72GB.
Your random speeds at 4k are pretty crap at best.
This Toshiba SSD doesnt warrent its price.
That C300 is hit and miss and i bet it wont look like that in 6 months time., Anandtech was right about that drive.
Ill bench my Corsair Force 240GB in 10 days time when my new MBP comes and see how it performs.
Other Sandforce Drives seem to be performing the best on OSX

It's amazing how many people (like you) think reviews are gospel and present statements like above as fact when you don't even own the drive.
Anandtech most likely had a duff review copy or hammered it to death with benchmark tools.
I've been running a 256GB C300 with original firmware since early March. 200GB used, several gigs rewritten daily and *no slowdown*.

Yeah, curious....How much of your hd have you used? I've only filled up 105gb of the 180gb. Maybe that's why?
proportionally we are about the same.... I have about 50GB filled of the possible 110GB. I would figure more stuff on it would mean slower... haha
Just wait, someone will chime in with the reason or at least a funny explanation of why they think so haha

NO!!!!! I am not willing to accept that haha at least not from you lol
(If you get on AIM to install my wireless printer drivers... I will accept it)
