Hello all,
I recently bought a Samsung 830 256GB SSD thanks to you guys. After installing Windows 7 on it I loaded Windows 7 SP1, MSE and a few other programs, one of which was Samsung's "SSD Magician" program. The disc came with version 3.1 of the program, but even after installing it asked to update to seemingly the same version. I checked the About box and apparently it updated from 3.1 to 3.1.1. Using SSD Magician I performed a firmware check (I had the latest version on the drive) and a "Performance Optimization" (not "OS Optimization") on the drive. After that I loaded up AS SSD and did a test, comparing it to my older 64GB Crucial m4.

I'm using AS SSD version 1.6.4237.30508.

When I got my 64GB m4 back in August of 2011 I did two tests on it. One got a final score of 531 and the other 526.

[EDIT=Added test scores]
Since I don't feel like hosting images forever somewhere, here are the text results of the tests:

Crucial m4 Test 1:
Read:
Seq: 264.76 MB/s
4K: 25.83 MB/s
4K-64Thrd: 181.48 MB/s
Acc.time: 0.107 ms
Score: 234

Write:
Seq: 106.98 MB/s
4K: 73.89 MB/s
4K-64Thrd: 90.34 MB/s
Acc.time: 0.262 ms
Score: 175

FINAL SCORE: 531

Crucial m4 Test 2:
Read:
Seq: 265.44 MB/s
4K: 26.61 MB/s
4K-64Thrd: 180.76 MB/s
Acc.time: 0.110 ms
Score: 234

Write:
Seq: 105.33 MB/s
4K: 67.58 MB/s
4K-64Thrd: 91.58 MB/s
Acc.time: 0.261 ms
Score: 170

FINAL SCORE: 526

Samsung 830 Test 1:
Read:
Seq: 263.17 MB/s
4K: 19.66 MB/s
4K-64Thrd: 146.31 MB/s
Acc.time: 0.088 ms
Score: 192

Write:
Seq: 78.78 MB/s
4K: 2.15 MB/s
4K-64Thrd: 10.61 MB/s
Acc.time: 1.838 ms
Score: 21

FINAL SCORE: 310

As you can see the write speeds are much lower on the 830 and only gets a score of 310.
[/EDIT]

Any reason why this is? Does this drive just perform better on a SATA III port?

Here are my specs:
Motherboard: ASUS SABERTOOTH 55i, BIOS version 2003
CPU: Intel Core i5-750 Lynnfield 2.66GHz LGA 1156 95W Quad-Core BX80605I5750
RAM:
1 x G.SKILL Ripjaws X 8GB (2 x 4GB) DDR3 1600 (PC3 12800) F3-12800CL8D-8GBXM
1 x G.SKILL Trident 4GB (2 x 2GB) DDR3 2000 (PC3 16000) F3-16000CL9D-4GBTD
Video Card: Sapphire Vapor-X 100283VXL Radeon HD 5770 1GB
PSU: Corsair HX750 (CMPSU-750HX) 750W
SSDs/Hard Drives:
1 x Samsung 830 MZ-7PC256B/WW 256GB (internal)
2 x WD Caviar Green WD10EARS 1TB 5,400 RPM (internal, RAID 1, storage/backup)

Are the scores for the transfer rates in MB/s? SATA II only supports up to 300MB/s while SATA III is 600MB/s so that is the reason for the slow speeds if it is in a SATA II port. SATA III will make a huge difference.

No. AS SSD doesn't spit out final scores in MB although there are other parts of the test that do. See edited post above for complete test results and scores. Thanks!
