Escinic Posted November 19, 2011 Share Posted November 19, 2011 Hi, I've had some problems with the HD since I got it, but since I've upgraded the firmware and upped the PCH voltage to 1,15 v the disc seems stable. But i still got one problem: ----------------------------------------------------------------------- CrystalDiskMark 3.0.1 x64 © 2007-2010 hiyohiyo Crystal Dew World : http://crystalmark.info/ ----------------------------------------------------------------------- * MB/s = 1,000,000 byte/s [sATA/300 = 300,000,000 byte/s] Sequential Read : 178.170 MB/s Sequential Write : 102.646 MB/s Random Read 512KB : 192.862 MB/s Random Write 512KB : 102.005 MB/s Random Read 4KB (QD=1) : 17.335 MB/s [ 4232.2 IOPS] Random Write 4KB (QD=1) : 66.902 MB/s [ 16333.6 IOPS] Random Read 4KB (QD=32) : 80.181 MB/s [ 19575.4 IOPS] Random Write 4KB (QD=32) : 90.465 MB/s [ 22086.1 IOPS] Test : 4000 MB [C: 57.8% (64.5/111.7 GB)] (x5) Date : 2011/11/20 0:47:39 OS : Windows 7 Ultimate Edition SP1 [6.1 Build 7601] (x64) The disc is listed with 550mb/s read and 510mb/s write. Do any of you have a tip to how i can get the disc running to its full potential? Link to comment Share on other sites More sharing options...
FoLmEr Posted November 20, 2011 Share Posted November 20, 2011 Test it with ATTO. The promised numbers are based on that benchmarking app only. There's a link on the left. All other benchmarks will be lower as they employ non-compressible data to test with (at least as default). Link to comment Share on other sites More sharing options...
madnisman Posted November 20, 2011 Share Posted November 20, 2011 Please perform an ATTO benchmark and post your results here. To which port is your SSD connected? Edit: FoLmEr was faster :sunglasse Link to comment Share on other sites More sharing options...
Escinic Posted November 20, 2011 Author Share Posted November 20, 2011 Hi guys, thanks for the quick reply. I ran the ATTO test, and like you said. I ended up with a far better testscore. Write 250mb/s, and read 390mb/s, (this was with the default setup in ATTO). But its still not 550/510mb/s any other tweaks I should consider? Im using the SATA 6/gb port Link to comment Share on other sites More sharing options...
FoLmEr Posted November 20, 2011 Share Posted November 20, 2011 you sure you're using the native Intel 6Gb/s SATA ports? Your results point me in the direction that you're not; rather the ports provided by the Marvell controller, which are BAD compared to the Intel ones. The ports are color coded. Check your motherboard manual and switch the disk to the Intel ports if you can. Link to comment Share on other sites More sharing options...
madnisman Posted November 20, 2011 Share Posted November 20, 2011 Yes, seems like 6GB Marvell SATA controller. Those ports are navy blue, you should connect your device to a gray port (SATA_6G_1). Link to comment Share on other sites More sharing options...
Escinic Posted November 21, 2011 Author Share Posted November 21, 2011 Yes, you are quite right. I am using the Navy blue one. I'll switch to the gray one, but do I need to wipe the disc? PS: I really appreciate the help you guys have given me. Link to comment Share on other sites More sharing options...
madnisman Posted November 21, 2011 Share Posted November 21, 2011 I'll switch to the gray one, but do I need to wipe the disc? Afaik there is no need to wipe the disc. To make sure you won't lost any valuable data, if wiping is necessary, make a backup copy of it and store it on a conventional HDD. After switching to Intel port, you may want to install Intel RST driver. If so, you should disable LPM in the registry for the port you connected the SSD to. P.S: Glad we could help you!

Escinic Posted November 21, 2011 Author Share Posted November 21, 2011 It worked like a charm. 553/514mb/s It even lowered the booting time cause I could disable the Marvel controllers. This case is closed. Thanks again! Link to comment Share on other sites More sharing options...
