Mac Pro :: SATA Copying Speeds Too Slow?

May 8, 2009

Based on what I've read about SATA, my Western Digital 1 TB Black Caviar drives should be able to read and write faster than 50 MB/sec. But that's the best I've gotten from anything. I thought I could expect 300 MB/sec, or 150 at the very least. What's the deal? This is a 2008 8 core 2.8 Mac Pro, by the way.

MacBook Air :: Why Wifi Download Speeds So Slow

Nov 1, 2010

I'm beginning to wonder if Apple put a lousy Airport card in the new MBA. No matter what the wifi hotspot, I get downloads of 2MB. I just bought a new Airport Extreme at home and I really thought the MBA would be faster.

Am I missing something here? Do I have to "match up" the MBA with my Extreme to use the fast "N" connection? Or is there some network setting to tweak on the new MBA?

IMac :: Slow Download Speeds For Certain Files - Why?

Nov 26, 2010

I have the 27" inch quad core i7 imac I just got a few days ago. Some reason for certain things like d/ling the vlc players its taking a few minutes to d/l a 24 meg file. With this type of computer, it should take like 3 seconds to d/l a small file like that. I have a fast internet connection, don't understand why that's happening.

OS X :: Ultra Slow DL Speeds On I5 Mac Wireless But PC Is Normal...

Feb 19, 2010

I just got my first Mac last week and I love it to death except for one thing. I can only get D/L speeds of about .7 - 1mbps wirelessly on my Linksys N router but my PC gets the full "advertised speed" (about 5.8) on wireless. This is very annoying and I have no idea what it could be. I don't really know what it does but I did some research and some people in other places recommended clearing the cache and I did. Nothing works, no reboots, no unpluggs, nothing.

Applications :: Slow Download Speeds - Experimenting With Torrent

Apr 27, 2010

I just started to use 10mbps instead of my old 1mbps. But it looks like I'm having some issues. First of all I'm using the port 27960 for bitTorrent and it is properly forwarded. (I have a Tilgin modem, it was really hard to forward). I was using uTorrent app with my 1mbps internet and it was doing fine. I was able to download at full speed (100kB/s). But when I changed my ISP things started to change.

The Test:
-I'm downloading 5 of the most popular torrent files. My friends with the same ISP as me can download these torrents 2MB/s at their homes.
-I'm using Vuze, uTorrent and Transmission as the torrent app.
On all applications my Port seems to be open. I have green light.
On Vuze;
-It is a little complicated for me. And it hangs usually. So I'm not using it.
On uTorrent;
-My download speeds up to max 250-300kB/s (Total download, not per torrent.)
On Transmission;
-Well, this is the strangest. My download speed goes up to 700kB/s. But it goes like 5kB/s, 15kB/s, 3kB/s, 1kB/s, 400kB/s, 600kB/s, 3kB/s. Slowest speed for a second and highest for another. It doesn't stand still. It goes up and down continuously.

So I had a phone call to my ISP and they said there is no problem with the lines. Than, I tested with "speedtest.net" and "speakeasy.net/speedtest/". All turned out perfect! (9.7mbps to 10.1mbps) Than I tested real download speed with Firefox.[URL] It is downloading with 980kB/s. Perfect again. But when it comes to torrents, something goes wrong. I'm not using any antivirus or firewall.

Mac OS X Lion Server :: Slow Fileshare Transfer Speeds Using SMB

Mar 25, 2012

I'm running Lion Server on a Mac Mini and using SMB to share files between the server and both Windows and Mac machines. I can't figure out why I can only get 2 Mb/s transfer speeds between the server and the other machines. I'm quite certain I'm not limited by my network and the disk write speeds clearly exceed 2 Mb/s. Possible to boost this speed or is this an actual limit of SMB or Lion Server?

MacBook Pro :: Slow Download Speeds On Macs V's Windows?

Apr 29, 2012

i have newish MBP and iMac.  I also run several windows 7 based pc's.  Over the last couple of weeks the download speed on both mac's has declined badly.  Trying to download drivers for an HP printer yesterday and was downloading at around 25kbps on both macs, ended up downloading on windows pc at around 800kbps instead, same with any other downloads, was getting over 1.2mbps on windows last night whilst my macs struggle toexceed 30kbps making them almost unusale.  I am a relative newcomer to apple, love build quality and feel but am nor too happy with this situation, have tried using different internet connections too - tethering to my cell, same result - 2 different machines so it seems to me the issue sits somewhere within Lion.

MacBook

Mac Pro :: Very Slow Transfer Speeds With External Hard Drives Through Firewire And USB?

Nov 30, 2008

My external drives transfer very slowly on my MacPro. I've been searching for answers and have turned up very little.

Just to make a note, I measured my disk speeds with both AJA System Test and copying files between drives and reading the Disk Activity in Activity Monitor.

I have 3 external drives, all MyBook Premium or Professional, 1x 500GB, 1x 1TB and 2x 1TB in RAID 0. I had them on Firewire 400 and the RAID 0 2TB one on Firewire 800. My transfers on FW were all around 24MB/sec on all drives (much less than what I should be getting with FW400). I then read somewhere that the FW bus on the MacPro uses the slowest speed connected for all FW connections. So I unplugged everything but the FW800 Raid 0 drive and my transfer rate jumped to 40-60MB/sec. This is much better, but still about half or so of what I expect it should be producing from an external RAID 0 setup.

To keep my FW800 backup drive faster, I've plugged the other two into USB2.0. The transfer speeds on both drives are now hideous, around 10-15MB/sec. This is so slow, but I'm not sure what to try to fix my speeds.

The HD's in the external drives are all 7200rpm, and all should be transferring at a higher rate. Do you have any suggestions or ideas? Ideally I'd like to get everything transferring at rates they should be transferring at, but I'll settle with my current FW800 speed of 40-60MB/sec if I can get my other two drives transferring at a non-snail pace.

Is this a common issue? I can't believe I'm the only one plugging multiple external hard drives into their Mac Pro. I hope someone has a fix or solution for this. I'm all ears!

Hardware :: Airport Express Splitting Bandwidth 50 / 50 Resulting In Slow Internet Speeds

Mar 10, 2009

I'm using a new AirPort Express updated with the latest firmware and AirPort Utility and both my roommate and I have been banging our heads against the wall. Speed to the APE is 130 Mbit/sec and both of our computers are connected to the APE just fine. This is what the ping looks like Ping has started ..

15 packets transmitted, 15 packets received, 0% packet loss round-trip min/avg/max/stddev = 151.575/154.369/156.210/1.359 ms. When I did a speakeasy test, it turned out that I am getting exactly half of our allotted bandwidth. Is there a way to configure this APE to act more like a router that truly shares a connection rather than a splitter that's cutting it in half?

PowerPC :: Slow Internet Downloading Speed / Download Speeds On Average Around 405kbps

May 2, 2010

i've got a 6 year old 12 inch powerbook G4 1.33 ghz that has internet speeds around 5177kbps, but overall its a bit dated sooo I wanted something a bit more new. I recently picked up a white 2.4 ghz Intel Core 2 Duo Macbook, HOWEVER the internet wireless speeds on it is dismal in comparison. I'm getting download speeds on average around 405kbps and upload speeds are pretty much non-existant! I've matched both of them to the same internet settings and they are both running 10.5.8. So again I'm stumped and if anybody can give me some idea as to what to do, Id greatly appreciate it!

Mac Pro :: Slow SATA Performance In XP/Bootcamp On Mac Pro 09

May 19, 2009

Is anyone having slow SATA performance on their 09 mac pro in bootcamp. Just booting into windows takes a long time and trying to burn a disc or transfer something to an external hard drive takes a long time. I created a large iso file and burned it to a BD-50 RW disc in windows and it took approximately 4 hours and it was set to burn at the fastest speed which should of been 2x but never reached any faster than 0.7x. I burned the same iso in mac osx through disc utility and it took less than 2 hours. I transferred the same iso file to an external usb hard drive in windows and that took 4 hours which is extremely slow. Does anyone know how to get SATA operating at a normal speed. I checked in the device manager and it is set to operate in DMA mode.

OS X :: Mac Extremely Slow At Copying Files

May 28, 2009

I just did a clean install of the mac and I'm noticing it is extremely slow at copying files back from an External HDD. It is on USB 2.0 connection, and still going maybe 10MB/minute. This is the speed I'd expect from a 1.0 connection. I've checked the wires, everything is connected. I thought maybe I'd speed it up by using an External DVD drive to copy the 20GB music library back from the DVDs rather than the external -- but the external DVD drive showed the same slow speed. The drive didn't even seem to spin up to read faster (like it normally would, it reads/writes quicker than the slot drive on the imac).

It just ran as slow as possible, with the same slow transfer rate. I've been going for a couple hours or more now, and only have 4GB of 16 copied over. I'm guessing there could be a reason for this that I'm missing. It's a fresh install, all updates installed on this Tiger 10.4.11 OS X. External is formatted HFS+ and the iTunes library does not contain any single file over 4 GB, or even close to 1GB. (just music/library files). There has been no problem with the media before.

MacBook Pro :: Upgrading 15.4" 2008 Internal SATA HDD To SATA II?

May 5, 2012

Im considering purchasing a higher capacity internal hardrive around the 750Gb/1Tb mark. However my macbook is the early 2008 model, and it seems the majority of hardrives are SATA II, having speeds of 3Gbt, which my mother board may not be capable of (apparently only 1.5Gbt) From researching and reading some reviews of others who have purchased internal drives on Amazon UK, some have had difficulty due to this problem, but have been able to fix the issue with a firmware update reducing SATA II drive speeds to 1.5Gbt. 

Questions I have: Do all SATA / SATA II internal hardrives need a firmware update if replacing on to a new computer?(If so, would I need to look for a specific firmware update for the specific drive I intend on buying? And if you're in the knowledge would you mind posting links to these updates?)What is the process of updating the firmware i.e. would I need to put firmware on external usb hardrive 1st, then upload it to macbook after installing new internal drive (if it boots up my OS that is) etc.     Would a 'hybrid' (disk+solid state) drive be compatible with a macbook as old as mine?Do I need to update my operating system to OS X Lion first, or can it be done after installing the drive?

Power Mac G5 :: Difference Between SATA And SATA II / Compatibility

Dec 18, 2007

I'm looking for a new HD to replace the original, now failing Maxtor drive in my G5 tower (1.8 Ghz dual processor, purchased in Aug. 2004), and have just about settled on the Western Digital Caviar SE16 series. It seems there are two types -- SATA and SATA II -- and I'm not sure about how to make a decision on which particular WD model to buy.

Will either type work in my machine? Or would the SATA II have potential compatibility problems? I read somewhere in these forums that someone with a G5 had bought an SATA II drive, and it wouldn't run with his system. (He said he had to reset some jumper switches to reduce the transfer rate of the drive ??, but now I'm told elsewhere that SATA drives don't have jumper switches.

1.8 DP G5, 1.5 GB RAM w/ Superdrive

Hardware :: SATA Versus SATA II

Dec 9, 2009

I am now shopping for a new internal HD of MAC G5; previous HD died. I have decided on a Western Digital and was about to order one when I became alarmed by the SATA II listings. Is there a difference between SATA and SATAII that I should be concerned about the comptability? Don't want to get it and find out it doesn't work!

Mac Pro :: Different Speeds On 2 Identical Drives?

Nov 13, 2010

I have 2 WD Caviar Black drives that are installed in my Mac Pro. Both show the exact same part number in Disk Utility, both are less than half full, both verify fine with Disk Utility. However one shows 125-130 MB/s RW with AJA and the other only delivers 90 MB/s. What gives? Just a sub-standard drive? THey are in adjacent bays in the MP, used as is - nothing changed. They are OEM drives thru Amazon from a few months ago. Both were erased and formatted prior to putting them in the MP a few weeks ago.

PowerPC :: Finding Pci Speeds On G4?

The 64 bit 33MHZ PCI slots on a G4 are running at 133MBps correct? Also I want to know if all 4 of them are running fully inpendent from each other? So if I have a RAID card in there I can get the full 133MBps and will not be robbed of speed if I have a neighboring Firewire 800 or SATA RAID next to it.

MacBook :: Fan Speeds Not Detected?

Mac Mini :: Different Cache Speeds - Put More RAM

Jul 6, 2010

I have a Mac Mini Core Duo 1.66. Macs are VERY expensive here, and I know I cannot change my crappy Intel 950GMA video card. So What else can I do? I've read about people using Core 2 Duo processors, which one is the best I could get for my Mini? The processors aren't that expensive here, but there's the fact that a lot of them use different cache speeds. Also, with another processor, could I put more RAM in it, since my mini is limited to 2GB (it came with 512MB and I replaced it with 2 after 1 week). Anyone could tell me which is the best processor I could put in such a machine, since I'm stuck with this stupid video card and answer me if I can use more RAM if I upgrade the processor?

Mac Pro :: Hardware Acceleration - Browser Speeds

Dec 26, 2010

Since we still seem to lag without hardware acceleration, just thought I'd give the new opera 11 a run, not quite scientific, but just my own interest.

On Peacekeeper -
Opera 11.00.1156 - 7213
Safari 5.0.3 - 5116
Chromium 10.0.603.0 - 5088
Firefox 4.0b9 (20101226) - 4762

And then a javascript (sunspider) test, but only with chrome, since thats what I use. Chromium 10.0.603.0 - 243ms. Opera 11.00.1156 - 273ms. So looks like its now on par in the javascript and the best at html5 rendering so far interesting, also finally has extensions!

I know there are a ton of products out there which help to 'increase' your download speed. I am looking for an application that can control the download/upload speed.. slow it down or increase it.

Also, is it possible to slow down the download rate.. but keep the upload rate the same? Tried looking for products which can achieve this but can't seem to find any.
