Just put this into the rig in my signature, attached to the SATA III port with this

http://www.newegg.com/Product/Product.aspx?Item=N82E16812123107 cable.

Installed the magician software, changed everything recommended (IDE to ACHI, etc.) and ran the magician benchmarks as well as AS SSD :

Boot times are around 50 seconds, which seems super high, but maybe my expectations were too great. Apologize not having just a screenshot, can't get the attachment function to work atm.

Thoughts? Advice? Is this just a bad drive?

Move the SSD to an Intel SATA2 port. Seems people got alot of issues with those bolted on Marvell controllers.

I assume you reinstalled Windows on your SSD. And also made sure its not actually booting from a HD.

50 seconds is not an acceptable boot time. Something is definitely not right, this much is true.

Yep. The Marvell controller on my Gigabyte motherboard does not work well with SSD's. A Samsung 830 runs best on the Intel controlled SATA II port.

My computer with an SSD does not boot super quick. Pretty sure it has to do with the Intel Storage Controller.

Also, remember with boot time, if you are counting from when you push the power button & have a standard BIOS, approximately 30 seconds of that IS the bios, which the SSD has no effect on.. That means your boot time is probably in the 20-30 second range.
To get fasre than the '50 second' you need a motherboard that uses UEFI (some gigabyte boards do - but need the bios updated to UEFI)

Will the manual just tell me which of those ports is the Intel-controlled one?

Edit: also, that is dumb, if true. Get your shit together, Marvell.

Yes. The Marvell controlled SATA ports are called "GSATA" ports, usually on the end of the row of SATA ports, most likely ports 6 and 7. I don't recall for sure, but they may be white or yellow, the SATA II ports controlled by the Intel chipset are blue.

Intel Sata 6gbps ports are typically white on newer 7 series boards.

Makes sense. At school now but I know I've got 6 blue GSATA-labeled ports and two white SATAIII ports right under the end of the gpu.

I did initially have it plugged into the SATAII ports, however, before putting it into the SATAIII, and benchmarks were the same (though I hadn't switched to ACHI or run the OS optimization from the magician software, don't know if that would make a big difference but I can't really see it). I'll switch if back this afternoon, rerun everything, and see what happens. Silly me for assuming that the SSD would run at rated speeds right out of the box.

I don't think it's the SSD. Pretty common knowledge that the Marvell controller on the Gigabyte P55A boards is not really going to pull 6G speed. Remember that the drive specs are for SATA III, since the Gigabyte mobo you(and I) have is only good for SATA II, it's not going to reach those advertised benchmarks.
I can tell you that even with an SATA II interface, the Samsung 830 is much faster than any mechanical hard drive. Switch over to AHCI and run the Optimization Wizard. Are you running Windows 7?

Also depends on where the primary boot sector is located, may still be on the HDD. Just because your OS is on the SSD doesn't means that it is booting from it first. On my setup, Windows 8 is installed on a separate partition on the HDD, not on my SSD with Windows 7. The computer hits the Win 8 boot manager on the HDD first, then the SSD depending on my OS selection.

Those scores do seem REALLY slow. I normally don't take benchmarls too seriously, but your scores are just too far out. My 256 830 SSD gets an ASSD benchmarl of:

Read - 348
Write - 178
Total - 704

One thing about As-SSD is that the benchmark scores greatly depend on cpu power. So my scores are much higher now than there were when I had this same SSD in my old laptop. The old machine was a Core 2 Duo, and the4 total score was around 300. You setup should score a bit higher, though.

it looks like you might still be using IDE mode...

My scored below, for comparison, using a Core i7 (gen 3) laptop:

Well, I did not know it, so shame on me. I know it's faster, I just want it to be SUPER fast.

Switched to AHCI, ran the optimization wizard, and yep, Windows 7. Processor is the i5-760, which I didn't know would influence SSD speeds, so maybe you're right.

So plugged it into the blue intel SATA_0 port, went into Bios and made sure it was in AHCI (there was a second option further down, in addition to the one the interactive manual said I should switch to AHCI, that I switched to as well, don't know what it did specifically), rebooted, re-ran the OS and SSD optimization software, then re-ran AS SSD.

Benchmarks look better, significantly in fact, and boot-up time is about five seconds quicker as well:


<?xml version="1.0" encoding="UTF-8"?>
-<ASSSDBenchmark XmlFormatVersion="1"> -<Information> <Name>SAMSUNG SSD 830 Series ATA Device</Name> <Firmware>CXM03B1Q</Firmware> <Controller>msahci</Controller> <Size>238.47 GB</Size> <DateTime>8/23/2012 11:04:42 PM</DateTime> <BenchmarkVersion>1.5.3784.37609</BenchmarkVersion> <Mode>MB/s</Mode> <Note/> <Signature/> </Information> -<SeqTest> <Read>254.20 MB/s</Read> <Write>245.74 MB/s</Write> </SeqTest> -<Random4K1TTest> <Read>13.59 MB/s</Read> <Write>41.61 MB/s</Write> </Random4K1TTest> -<Random4K64TTest> <Read>184.73 MB/s</Read> <Write>102.64 MB/s</Write> </Random4K64TTest> -<AccTimeTest> <Read>0.121 ms</Read> <Write>0.093 ms</Write> </AccTimeTest> -<Score> <Read>224</Read> <Write>169</Write> <Total>511</Total> </Score> </ASSSDBenchmark>

Only other thing I can think of is bios revision, but that would only affect startup times, right? I suppose this may be the best I can hope for. Perhaps a new processor, like someone above mentioned, may be the thing keeping me from ~450MB/s speeds. I just can't think of anything else...

That's not me, it's someone else. I'm still seeing little more than half of that

That's because your motherboard does not have a 6G Intel port, the 6G port on the P55A board is a Marvell port which does not pull 6G.
Google "change to AHCI without reinstalling Windows". There is a registry key you may need to change for max performance.
