greythorne Posted April 8, 2010 Share Posted April 8, 2010 Anyone see this after 10.6.3 update? See the Negotiated Link Speed? I bet this was not in 10.6.2, but appeared on 10.6.3. Somehow i feel after the update response seems to be slow on my mini. Care to comment on this. Thanks Link to comment Share on other sites More sharing options...
crazzyyfool Posted April 8, 2010 Share Posted April 8, 2010 Are you using a stock HDD? Link to comment Share on other sites More sharing options...
iKenndac Posted April 8, 2010 Share Posted April 8, 2010 In 10.6.3, this piece of information was added to System Profiler. Note that this is new information - if your hard drive negotiated 1.5GBit in 10.6.3, it negotiated 1.5GBit in earlier versions of the OS as well - earlier versions just didn't tell you. As for the computer feeling slower, that's probably either psychological or something else - unless you're using a kickass SSD, your drive won't be saturating 1.5GBit, never mind 3.0.

greythorne Posted April 8, 2010 Author Share Posted April 8, 2010 yup its the stock hard drive which is a fujitsu. Ok since thats the case then be it. Didn't know that previously also like that and the information was newly added. Link to comment Share on other sites More sharing options...

Didn't know that previously also like that and the information was newly added. Are you sure it is the hard disk that it is referring to or the cd/dvd drive? I have a MacBook Pro and the DVD/CD is negotiated at 1.5Gbps. Link to comment Share on other sites More sharing options...

.Neo Posted April 9, 2010 Share Posted April 9, 2010 With my Mac Pro my SuperDrive runs at 1.5 Gigabit, my HDD 3 Gigabit Link to comment Share on other sites More sharing options...
rawr_boy81 Posted April 11, 2010 Share Posted April 11, 2010 Its for both the hard drive and superdrive. Is it a stock standard drive that came with the Mac or did you upgrade it? I know for some drives they default to 1.5Gbps as standard for the sake of compatibility thus requiring you to manually set it to 3Gbps. Here are the details from my hard disk, its Fujitsu and I am very happy with it: NVidia MCP79 AHCI: Vendor: NVidia Product: MCP79 AHCI Link Speed: 3 Gigabit Negotiated Link Speed: 3 Gigabit Description: AHCI Version 1.20 Supported SAMSUNG HM641JI: Capacity: 640.14 GB (640,135,028,736 bytes) Model: SAMSUNG HM641JI Revision: 2AJ10001 Serial Number: Removed for privacy reasons lol Native Command Queuing: Yes Queue Depth: 32 Removable Media: No Detachable Drive: No BSD Name: disk0 Rotational Rate: 5400 Partition Map Type: GPT (GUID Partition Table) S.M.A.R.T. status: Verified Volumes: Macintosh HD: Capacity: 639.79 GB (639,791,054,848 bytes) Available: 611.94 GB (611,942,465,536 bytes) Writable: Yes File System: Journaled HFS+ BSD Name: disk0s2 Mount Point: / Link to comment Share on other sites More sharing options...

.Neo Posted April 15, 2010 Share Posted April 15, 2010 The Mac mini has a relatively slow (compared to full 3,5" HDDs) laptop sized drive so I don't really see the problem here. Link to comment Share on other sites More sharing options...
greythorne Posted April 16, 2010 Author Share Posted April 16, 2010 how do you set the speed manually? Link to comment Share on other sites More sharing options...
rajputwarrior Posted April 16, 2010 Share Posted April 16, 2010 how do you set the speed manually? its more to do with the HDD or the jumpers on the HDD. It's rather the HDD only support 1.5 or theres a jumper setting it to 1.5 (usually becuase the chipset only supports 1.5, which in this case that's obviously not the problem) Link to comment Share on other sites More sharing options...
rawr_boy81 Posted April 17, 2010 Share Posted April 17, 2010 how do you set the speed manually? What model is your hard disk? have you gone to the hard disk manufacturers support page to download the enabling/disabling features software? Link to comment Share on other sites More sharing options...
.Neo Posted April 17, 2010 Share Posted April 17, 2010 Again, are there any benefits of having a laptop HDD that connects through SATA 3 Gigabit? Link to comment Share on other sites More sharing options...
rawr_boy81 Posted April 17, 2010 Share Posted April 17, 2010 Again, are there any benefits of having a laptop HDD that connects through SATA 3 Gigabit? Not really - I'd love to see a hard disk reach 3 Gigabits per second - it would pretty much invalidate the need for flash drives lol Link to comment Share on other sites More sharing options...
