Why do my Samsung 830 SSD Speeds Suck?

S-ATA 1.5 Gbps (S-ATA I) is the reason.
You can use the following applications to benchmark the speed of your SSD, to see, if S-ATA 1.5 Gbps (S-ATA I) and not the application is the culprit:
And you can look into System Profiler (System Report on Lion) > Hardware > Serial-ATA, to see, that you have an S-ATA 1.5 Gbps (S-ATA I) interface.

Yep, exactly what the previous poster said. Your MBP doesn't support the maximum speed the drive offers.
190 to 230 MB/s, but the random access time is the real killer of slow HDDs.
While one does not write big chunks of data onto the same HDD the data is from (like duplicating a file GBs in size), having that fast random access time is even noticeable on an S-ATA 1.5 Gbps (S-ATA I) interface.
A good example might be boot times and application startup times, where data from various locations have to be read, or reading from cache (which happens in the background).
Perhaps suggest an alternative that he could use if his original drive can be returned....
Which you just did?
Any Sata II drives would be great. Intel 320, Samsung 470, Vortex drives, OWC drives.
Don't know if it pays to return it and get something different as long as you know that you are limited to the amount of speed you will get from that drive
Here's the Xbench results. How can I tell if it's the SATA-1 not the application?

System Profiler (System Report in Mac OS X 10.7 Lion) > Hardware > Serial ATA > Link Speed, as mentioned before.
The maximum transfer rate for SATA 1.5 GBPS is 157 MB/s and so your benchmark reflects that almost exactly. It's still a great drive and if you ever decide to upgrade, then you already have future-proofed SSD (so you can buy one with the most basic HDD and save $) so personally I'd keep it. Even 157 MB/s over a HDD from that era is a tremendous gain.
go in to your about this mac > more info/system report > check under serial-ata. check the negotiated link speed. if it shows 1.5, then you won't get much of a boost. if it says 3, then you'll probably see a speed increase.
And?
Your post history, six posts since you registered today, seem like you are a SPAMMER.
your computer has only sata I. So, while the drive is very fast, the bottleneck is the speed that the drive can transfer data to and from the rest of the computer.
However, most hard drives can do about 60-80 mbps, so you're still doing about ~2 times faster than your old hard drive.

Right. I am actually really happy with the performance over my old HDD. I will keep it. Really don't have a choice. But I'd keep if if I did.
i would like to put a ssd inside my new comeing ivy bridge macbook, but am trown between kingston, owc and the allready existent samsung in macbook. can anybody tell me witch of them is best in speed? thz
ps: i want o course a 480-512gb ssd

Yeah, I just noticed. It is a SPAMMER and that is one of their tactics.
After a certain amount of posts, a signature with a link will be added.
Or as you can see, small .gif files, that give the server they reside on some traffic. Now the mod has to delete this too?
You could be a little more diplomatic when conveying your thoughts.
Samsung 830 or Crucial M4 or Intel 510/520/320. And unless things have changed, the factory one is a Toshiba SATA 3.0 Gbps, so any 6.0 Gbps SSD is going to be faster (and cheaper if going above 128 GB)
