Here's one that performed better than expected when carried out on my main play system (4 yr old):
Long Bench 32MB Zone Maxtor 82GB 7200RPM 8MB Buffer UDMA 6 (3 yr old, 62GB full) AMD Duron 1.3GHz 300W Generic PSU 1.5GB DDR400 Sequential Read Speed Peak = 61MB/s Burst Speed = 100.8MB/s Random Access = 14.9ms CPU Utilization = 8% Av. Read = 49.3MB/s Repeated with my professional system Kentsfield 2.66GHz Quad core OCZ Ballistix Tracer DDR2800 4GB Seasonic 650W PSU Sequential Read Speed Peak = 72MB/s Burst Speed = 121.5MB/s Random Access = 11.0ms CPU Utilization = 1% Av. Read = 57.9MB/s Some difference there. The rest of the drives here with me are ITB and 1.5TB external through FireWire800 and SCSI (which aren't compatible with the older spec AMD), so I'll leave them for now.

I've done this three times now to confirm. This is my professional system setup usually running off the PCIe X8 slot. The difference is double. ![]() |

ATTN: Blackduck, download link for HD Tach is Dead
FYI: the current link to download HD Tach is coming up dead.
I was going to contribute some of my drives to this thread but want to make sure you are using the same version as myself. Quote:

Bottleneck obvious? HD Tach Scores
Seagate ST3500630NS3 SATA/300
Controller Sil 3112 Computer Dell Precision 530 Dual Xeon 2.4GHz 2GB Rambus Sequential Read max 82 MB/s (read from graph) Burst 102.7 MB/s Random access 13.6 ms CPU 2% Average read 65.4 MB/s This drive should, according to several reviews, be the fastest thing my money can buy. But it is MUCH slower than my old 32 GB SCSI ultra160, for example going into hibernate on the old drive takes about 3 seconds while on this new one over 12 seconds! I'm aware that this is just a place to exchange test results but please allow me to ask if anyone has any suggestion what the bottleneck might be and / or how to solve it. |

Re: HD Tach Scores
@ Scarcan
Sata II drives (300mbs) are not yet faster in real world use than their 150mbs brother. The 150 & 300mb/s speeds are theoretical speeds. You drive is performing to speeds that would be expected! SCSI still has advantages over SATA drives just not in the price structure. Sata has however, closed the gap between IDE and SCSI to a point where justifing the cost of SCSI is very difficult.

Re: HD Tach Scores
My problem are not as much the HD Tach results, but more the real life lack of speed feeling. It can't be normal that I have to wait 4x as long before the hibernate blue bar fills up? Starting every day progs like Paintshop pro, firefox, Acrobat are all equally slow. My old Seagate Cheetah hit the market around the turn of the millenium, 7 year old technology, not even SCSI U320. My brand new Barracuda 500GB SATA/300 should be faster according to several reviews.
I'm not the type of person to get bothered by a little bit less performance than reviews promise. But the presence of a bottleneck is in my case so self evident that it's really worrying. |

Re: HD Tach Scores
have you tried disabling power management features so see if that speeds the drives feel up?
sounds as if the drive might be running in the wrong mode ? go to your device manager right click on IDE controllers & sata controllers go to properties then advanced what are the drive speeds set at ? what are the current transfer modes set at ???

Re: HD Tach Scores
Found the problem. There appears to be a tiny incompatibility issue between Sil3112 controllers and Seagate disks, known as the Mod15write problem. So all I need is another controller.
Thanks Google, thanks forum members for suggestions |

Re: HD Tach Scores
actually not easy to find at all. Not a word on Seagate website, not a word on siliconimage.com. When I dived deep into my registry I found
HKLM\SYSTEM\CurrentControlSet\Services\si3112\ProblemDevices A lot of string values, all Seagate drive model numbers, all with data Mod15Write. After searching Google for Mod15Write I found a lot of forum sites, mainly Linux developers, discussing the mod15write problem in such programmers lingo that it still took me a lot of time before I got the picture. see for example http://home-tj.org/wiki/index.php/Sil_m15w which is in relatively clear simple lingo. So to let this forum be the first to have the whole picture for non-linux users in plain English (with a Dutch accent) Lots of Seagate disks are not 100% compatible with si3112 controllers. The results can be system hangups and bad performance. One workaround is adding your drive type to the list in the above registry key. This prevents system hangups but at a cost: even worse performance. The other workaround is either another controller or another drive. The brands using si3112 chips AFAIK are ATI, Dell, Gigabyte, IBM, Logitech, MSI, NEC, Sitecom, Sony, System Talks, Sweex and even Intel. Not happy and very curious how these companies have been able to hide this fact for so long. |

Re: HD Tach Scores
I have heard of such problems with NCQ (native command queing)and some controllers, but to my knowledge I have seen no similar problems with western digital drives.
I personally would email Seagate and maybe they could exchange drives with a model not effected by this incompatability ?
