Hardware :: Slow FW800 Hard Drive

Jan 9, 2010

I bought a MacAlly GS350SUAB hard drive enclosure for the firewire 800 port. Before I made the purchase, I looked around for some FW800 drive xbench scores and found a few results:

[URL]

When I ran the xBench disk test on my drive, I was unimpressed. They weren't much better than when I plugged it in using the USB port.

Uncached Write34.81 MB/sec [4K blocks]
Uncached Write43.62 MB/sec [256K blocks]
Uncached Read18.11 MB/sec [4K blocks]
Uncached Read46.06 MB/sec [256K blocks]

I thought maybe xBench was sucking, so I timed how long it took to write a 831MB file to the drive using both USB and FW800, and it was actually faster (marginally) on USB. FW800 took 30 seconds, while USB took 28. Something doesn't seem right. Does anyone have any thoughts on why this could be? I do have a FW400 audio interface hooked up, but that is of course plugged in to the FW400 port and shouldn't make a difference. The hard drive I'm using came out of a Seagate FreeAgent. Is it possible it's just a really slow drive?

Power Mac G5 :: Recommendations Of External FW800 Hard Drive

Dec 7, 2007

Could anyone recommend an external (FireWire 800) Hard Drive that they're using without issues with a Power Mac G5 (mine is a Dual Processor 2.3)?? I bought a couple of WD My Book Studio Edition but have no end of problems on FW800, and looking around here so is everyone else. LaCies seem to have similar problems, plus my own experiences in selling these and seeing FW ports falling off the enclosure's board, etc., puts me off them. Maxtors seem to have different issues and the new brown and orange Seagates are too fugly to even consider. So, anyone recommend a solution (250-500GB) that works fine with FW800 on a dual PMG5??

OS X :: PowerMac G4 FW800 2nd Hard Drive Install (as Slave)

Dec 31, 2009

I bought a brand new Seagate 400Gb hard drive for my PowerMac G4 MDD FW800. I installed it in the back bay, as a slave drive. When I power on the Mac, I get a blank grey screen. The original hard drive with OS 10.4.11 is set as the master, so I don't know why it won't boot properly. I've checked for bent pins, and I don't see any obvious ones, so I'm completely confuzzled.

OS X :: Best Bang For Buck FW800 - PATA Hard Drive Chashed

Oct 6, 2010

I got two questions.

1) What would you guys say the best bang for your buck FireWire 800 is? I hear a lot of differing opinions on this one, so I'd like a couple suggestions, need over 500GB though. 750GB and up would probably be the best.

2) I've got 2 PATA hard-drives from my old Windows PC that crashed, what would you guys suggest doing about getting the data off of them? Most of the hard drive kits I found are for SATA, and the one I found for PATA was like $50 at Best Buy, I just want to get the data off these hard drives and junk 'em. I don't need bells and whistles and fancy enclosures.

Mac Mini :: Hard Drive - Hybrid Internal Or 7200 External Via FW800?

Nov 12, 2010

This is in regards to the 2010 mini. I have been reading up on SSD, Hybrids and FW800 with a 7200. What is the easiest AND most effective/cost effective solution? If I went he FW800 route, can I use the same drive as my data storage drive? Will there be enough headroom to run the OS over FW and use the drive to stream movies playing in another room on Apple TV2 simultaneously? Will this give me a performance increase over the internal 5400 if I use the external 7200 for everything over FW800?

That is where my thoughts about the hybrid come into play. I know I can stream the iTunes content over USB2, which I have at the moment for the big drive. I would need to go buy an enclosure with FW800 to run it as a boot drive. I could use that same money and go get a 500GB Hybrid drive and install myself and leave the USB2 as data only. If the install is painless but tedious, I might just do that. If the FW800 route would be robust enough to run the OS and stream data to other devices simultaneously (ie use it as I would the regular internal drive), I might just do that and wait for SSD prices to come tumbling down and do a bigger internal SSD in the future.

MacBook Pro :: Just Wondering Why My FW800 Is Acting Unstable And Slow?

Feb 11, 2010

I recently got the mid range 15in MBP. The firewire 800 port is a particular interest of mine which I am expecting to be able to depend on and take advantage of. But much to my dismay it is very irregular, and many times drops down average USB2 speeds or even slightly less.

Now dont get me wrong, the FW 800 port has done almost double the the fastest I have seen USB do, but what I cant figure out is why this is only happening sometimes and sometimes this same FW is performing worse I have three different FW 800 drives now and have tried all sorts of things like switch cables, verify, repair, or check disks/permissions, and basically anything else i thought might help. Still, sometimes its really fast and other times, not.

I would say for the most part FW800 is transferring a little above USB speeds, which is better than nothing, but actually still disappointing. Anyway, if some one has any experience or advice about this, let me know.
I dont see why a drive will act one way once and another the next time. What might be effecting or causing this? Is this normal?

Windows On Mac :: Super Slow 4MB/s FW800 Transfer With Vista Ultimate

Nov 9, 2010

I have a 2010 13" MacBook Pro. I bought a FW800 enclosure for my 500GB Seagate 5400rpm HD. In OSX using Path Finder to test transfer speeds I get around 40MB/s. Pretty good. Not as fast as it should be given the drive and FW800's possible speeds, but acceptable. When I switch over to my boot camp partition with Vista Ultimate installed I get 4MB/s. I can't figure out why I'm getting such slower speeds with Vista. I did the tests using the exact same files. So what am I missing? How can I get the transfer speeds I should be getting in Vista?

MacBook Pro :: 2010 13" Slow FW800 Transfer Speed

Nov 9, 2010

I purchased a FW800 enclosure for my Seagate 500GB 5400rpm HD. I just got a 2010 13" MBP. I was previously using a 2006 MBP with an ExpressCard slot, and had this hard drive connected over eSATA. According to TomsHardware the max sustained write speed of this drive is around 65MB/s, which is what I was getting over eSATA. So I got the FW800 enclosure now that I can't use eSATA with the thought that I'd be getting the same 65MB/s that this drive is capable of. FW800 should be able to handle up to 100MB/s. But I'm only getting around 40MB/s, closer to what I should be getting if I was using FW400.

Hardware :: Daisy Chaining FW400 Drive To FW800 Drive

Dec 7, 2009

I may soon buy one of the newer generation iMacs that drop the FW400, includes 800 only. On my current Mac, I have a FW800 drive and a FW 400 drive. I use the 400 for time machine as speed is less important. My current iMac has a 400 & 800 connector. I have tested connecting the 400 to the 800 drive via daisy chaining, so everything is pulling off the 800 connector, so this assures me I can do this with the new iMac. However, Does it slow down your 800 drive when it has a 400 chained off of it? Or, if the 800 is the first drive connected to your iMac, do you maintain full speed?

OS X :: External FW800 Drive Almost As Fast As Internal Laptop Drive?

May 16, 2010

I just bought a 640gig Samsung 2.5 inch / 5400rpm drive and threw it in a FW800 case from Other world computing. Running some test using the QuickBench 4 and AJA system test shows me that this little bugger is almost as quick as my internal drive on my MacBook Pro (Model number: WDC WD6400BEVT-00A0RT0). How can this be???? I did a varity of test with different file sizes and the Samsung get 70 MB/s vs about 84 MB/s for the internal drive.

My internal drive is pretty full vs this external drive that is currently empty. I do a lot of video work / large gigabyte files on the drive so perhaps I have a defrag problem? I really expected my internal drive to blow the FW800 connected Samsung out the water?

Hardware :: External Hard Drives And USB Vs FW800

Dec 11, 2008

I have been using a MBP for a few months now and I am making a total conversion from PC user to Mac user in January when I buy a nice new 24" iMac but to go with it, I want to buy a couple of new external hard drives. I have currently got a Seagate FreeAgent 500GB USB Drive which is Windows Formatted and I will be keeping that to use with my work laptop (a Dell), and I have been really pleased with its reliability. Anyway, I have been looking around and there are some fab drives on the market but I have a couple of questions. If I get an iMac with a 500GB Internal Hard Drive, how big an External hard drive will I need to use Time Machine without having to delete backups all the time?

Also, I have been primarily looking at the new Seagate FreeAgent drives and the do a PC version (USB) and a Mac version (USB/FW400/FW800), but the 640GB USB version costs �76 whereas the 500GB FW version costs �100. Would you go for the bigger size or the added benefits of FW800? Will I notice much speed difference between USB and FW800?

Hardware :: FW800 Enclosures (no Hard Disk) For IMac

May 20, 2010

So I am well on the way towards my 27" iMac. I have just finished transferring my files, work, backups and media from ext4 hard disks to hfs+ (via a combo of an OSX VM for disk util, and removing journaling/file-copying/re-enabling Journaling under ubuntu and the VM.

This has me left with 1.5TB and 2TB HFS+ disks and my old dual bay USB enclosure (an Icy Box). I now need to start looking for a good FW enclosure/s to home these two drives. I have had a look about and the Icy Dock dual bay (supporting raid and also JBOD - important for this) looks like a winner (waiting on techies to answer me about putting drives with data on them in the enclosure in JBOD as I dont want to lose data).

Are there any other options (most of the posts relate to single drive and/or supplied with disk enclosures). I really want something that is FW800 and lets me drop two disks in and just use them.

I may put up a wanted to see if someone has unused enclosures for sale (perhaps where they have removed the disks and put them in their shiny Mac Pro?)

MacBook Pro :: Copied Hard Drive Very Slow?

Jun 8, 2012

I recently replaced my stock HDD (500GB) with a 750GB. I went into the recovery partition, and did a disk copy. I figured cloning the disk would be the best way to do things. When it was done, I rebooted, and booted from the new drive (which was in an external enclosure). It was a little slow, but I didn't think anything of it. I opened up the case for my MBP and switched the drives. When I booted up after switching them, the boot-up process was very slow, and when OSX finally booted, everything was very slow (lagging) and unresponsive. I kept getting the "Grey Screen of Death" telling me to force shut-down my laptop. I have switched the drives back, and everything is working fine now, but I'm curious as to what may be causing the new drive not to work properly. Has this happened to others? Have I missed a step or 10?Should I maybe have used Carbon Copy Cloner instead of Mac's built-in disk copy?

OS X :: G Drive Attached Via FW800 Keeps Unmounting Itself

Sep 28, 2009

I have two new G-Drives attached via FW800. One drive keeps unmounting by itself. All of a sudden, I get a screen that says "The drive has been removed, you should always make sure to eject the drive properly from the etc etc.." First time I have ever had this problem. I have tried the eSATA connection and FW connection with the same result. Regardless on how I connect the drive, linked or direct. It's brand new. Could it be bad?

OS X :: Networked Hard Drive Is Slow Working Live From It?

Mar 29, 2010

i have a small mac office with a PPC G5 and an intel G5 as my two main boxes. I currently work from a very slow raid network box - no screen, just a networked hard drive really. problem is that it is really slow working live form it. Everything is fine when I copy files to my machine first then work on it.

I can't do this as I'm in the graphics field, and all my links, pics, blah blah are on the server - linking to things like InDesign etc.i need to upgrade in here and add a new machine, but not sure on which way in terms of software for my old G5.The PPC G5 is to become my server (its got to be better than my current network server). As per software tho, because its a non-intel G5, i read that i cannot upgrade to latest software. I'm currently running 10.4.11.

Do I, or, Should I, or for what reasons - would I upgrade to a 'server' software, rather than leave it as its current tiger 10.4.11 software (non software)basically, are there major security, network, etc features of the server OSX over non-server OSX?

OS X :: Does Using USB Hard Drive For Time Machine Slow Down The IMac?

Aug 27, 2010

Just finished setting up my new 27" iMac and the last piece of the puzzle is to setup Time Machine. I have an external 500GB hard drive that Im not using (even though my hard drive is 1TB, Im only using 157GB right now so the 500GB should be fine). My concern is...will it slow down the computer when its backing up since the drive is USB? Would it be worth buying a Firewire 800 external drive (~$150)?

OS X :: Hard Drive Dominating Computer / Systems Often Gets Slow

Apr 27, 2009

Here's my best try yet in describing it:My hard drive seems to be dominating my computing.Frequently, when trying to perform simple functions, I can hear my hard drive spinning often accompanied by a spinning beach ball. It makes my computing sluggish for a good handful of moments, then it is back to being smooth.

I can only compare it to times when i've worked on a machine that doesn't have enough RAM for everything I'm trying to do.The most recent occurrence- a few moments ago- was when I simply had a browser window open and my system profiler- there is 8 gigs of RAM in here.

MacBook Pro :: Hard Drive Clicking - Computer Slow Down

Jul 23, 2009

Recently my new unibody 17" macbook pro start to act a little weird. It started with regular "clicks" from the hard-drive. I thought the hard-drive is just parking to safe energy and didn't saw any harm in it. But now my computer start to slow down terrible in many occasions or crash. I noticed that when this happened (the crash or the slow down) I often hear the hard-drive clicking and/or bouncing. Is this the sign of a hard-drive that will die soon? or can there an other reason be the cause of this behavior?

MacBook Pro :: Hard Drive Slow Down Than Spin Back Up?

Jun 7, 2010

Last night, after a few hours of using it (from 100% to about 8%), I tried turning off the computer for the night. After the dock and everything else disappeared, I got a spinning beach ball of death. The computer wouldn't turn off for at least 15 minutes. I had to do press the power button for 5 seconds to get it to turn off. I restarted it this morning and it seems to be working fine for now, but I'm scared of turning it off again.

Here's what I know: while the beach ball was happening, my wallpaper was still on the screen, the trackpad worked, but the brightness and volumes didn't, so I'm guessing I was logged out and no files were corrupted.

During the beach ball, the hard drive would slow down, then spin back up. I waited until it had slowed down a bit to do the hard reboot. I have to say that I reset the PRAM yesterday morning, thinking it might be good because I changed the hard drive to the Momentus XT last week and I read that you should reset it when you change hardware inside the machine. I did that before the crash, so when it crashed, it was the first time I tried to turn the machine off since resetting the PRAM, could that matter?

This morning, I went to disk utility and repaired permissions, there were probably a few hundred bad permissions, but Mac OS fixed them. I also tried verification, but it was alright. I then ran the daily, weekly and monthly tasks and everything went great.

What should I do? I already have a charger problem and a �screen is too blue whichever way I set it� problem. Do I have a lemon here?

Intel Mac :: Wifi Slow After Changing Hard Drive?

Jun 4, 2012

So i opened up my mid 2007 iMac and changed the hard drive and cpu, and its all up and running correctly with a clean install of Lion, except that my wifi seems to be slow! It connects to the network and loads webpages slowly, and doing a system update it says it'll take 700hours to download the 1.5gb combined update... I then tilted back the screen and the connection speed improved and i managed to download the update in a couple of hours... so still a poor speed... Im guessing I either left the wifi card poorly connected or got the main and aux antenna cables wrong way round, does anyone know where the white and black cable go? Or which is which? Also, what do these cables connect to (the end not connected to the wifi card)?

Hardware :: Airport Extreme Write To USB Hard Drive - Slow?

Dec 17, 2010

Admittedly new to the world of wireless networking. Have my 1TB LaCie USB hard drive plugged into my AirPort Extreme. I had high hopes of keeping my iPhoto and iTunes libraries on this hard drive for access downstairs with my MacBook. Got it all setup tonight, and attempted to put a 1.5GB file from my MacBook on the hard drive. According to Finder it was going to take 8 hours to complete the transfer! Does this sound right? I realize USB is slow, but I didn't think that slow. The Belkin-N300 router I had before was faster than this on the USB sharing side.

Mac Pro :: Applications Are Starting Slow / Testing Hard Drive Speed?

recently I bought WD6400AAKS hard drive. I made to partitions (1st for OS and applications, 2nd one for photo files). I also did fresh OS install and loaded basic applications. Strangely I didn't notice any speed boost while booting and to be honest I feel like all applications (photoshop for example) are also starting much slower than on original hdd.

Is there any way to test hard drive if it performs as it should be? I also have 2 more older drives installed. is it possible that one of them would slow the system down?

Then I did a full restore from time capsule and everything is going downhill again.
