Just 150MB/s write in Blackmagic Disk Speed :(
I've bought Your (new) SSD. I've got Macbook Pro mid-2012. I've did 'clean' install Mac OSX Yosemite (latest system) - installed program Blackmagic Disk Speed test to check SSD speed - read is ok (about 500MB/s) but write speed is slow (about 150MB/s) which is far away from 500MB/s. Thing is - I've installed Windows 8.1 on my Macbook - and everything is ok - got about 500MB/s read and write. What is wrong with latest Mac OSX Yosemite? Especially even if I did "fresh" install system.
Hello, the speeds you are getting seem to be line SATA 1 so you have to ensure that the hardware of the mac is compatible with the drive and is of course sata 3. also the trim function of the ssd is deactivated on a mac from default so maybe that was the issue with the mac?

What's the expected hard disk speed for Mac Mini?
Hi all, I just bought my first Mac for use in my personal photo studio, a refurbed 2011 Mac Mini i5 2.5ghz. As I was setting up external drives and putting the mini through its paces, I ran a disk benchmark (BlackMagic Disk Speed Test) and got some pretty poor scores.
My mini's internal drive hits roughly 40MB/s for both sequential read and sequential write. Am I correct in thinking that this is poor performance even for a 5400 rpm drive? The drive is mostly full; there are 50GB free. Would you recommend that I address this with Applecare?
Here are two other Minis (same 5400 rpm drive) hitting much higher marks:

http://www.youtube.com/watch?v=uPksGswN8Uk#t=0m18sThanks for the response, Allan. I was preparing to move most of the data to an external RAID setup when I ran that benchmark. It made me think twice about spending several hours setting up the system if in the end the system drive needs replacement.
I'll move some data and see if the speed improves.
ps - One of the torx screws inside the mini case is misaligned. Noticed this when installing new ram. I guess that's making me a bit paranoid that the refurb process didn't go smoothly ;-) -
Hello, i just installed a vertex 2e 90gb ssd in my macbook pro 13" (8.1 early 2011). But when i do a disk speed test i only get 125 mb/s write speed and 146 mb/s read speed. Thats under 50% of what i should get. The disk have firmware 1.35 and 3 gb/s linkspeed when i check in systemreport.
Anyone know why i get so low speed from my ssd?Speak to the manufacturer. They did the bench tests.

How to find the max data transfer rate(disk speed) supported by mobo?
I plan on replacing my current HDD with a new and bigger HDD.
For this I need to know the max data transfer rate(disk speed) that my mobo will support. However, dmidecode is not telling me that. Am I missing something?
Here's dmidecode:

Last edited by Inxsible (2011-03-27 04:40:49)I just checked my BIOS and my current setting is set at IDE although it also mentions that the default should be AHCI. Currently I have a dual boot of Windows 7 (need it for Tax software) and Arch
So I guess, when I get the new HDD, I will first set it to AHCI and then install the OSes on it. See if NCQ helps any, and if not I will turn it back and re-install (if I have to). I am planning to have Windows only in virtualbox in the new drive.
Anyhoo, while I was in the BIOS I found two things which I had questions about :
1) Under Onboard Devices --> Integrated NIC , my setting is currently set at "On w/PXE" and it says the default should be just "On". Would it be ok to change it back to On since its a single machine and its not booting an OS on any server. I just don't want to have to re-install anything now since I will be doing that in the new HDD.
2) How would I know whether my BIOS would support a 64 bit OS in Virtualbox? I checked some setting under Virtualization, but they weren't very clear.
I will edit this post and let you know exactly what settings were present under the Virtualization sub-section. -
4 Gig Nano not updating/Cant write to this disk error. Please Help!
Hi. I have a Ipod Nano 4g. (actually my husbands.. but anyway) he will load it to his computer and it starts updating, recognizes it.. everything looks perfect then after about 4 songs sometimes 3 or 8.. but generally within minutes it stops updating and says "cant read or write to this disk" something like that. The restoring didnt help.
Its a desktop computer with XP on it.. any suggestions?just checking. have you worked through the possibilities from this document?

Dropped frames caused from slow disks (Disk Speed)
I just bought a hard drive enclosure that holds double hard drives. http://www.ewiz.com/photogallary.php?name=CA-400MXS2&show=g Inside the enclosure I put two 400G Seagate SATA drives and made them both scratch drives for my FCE 4 projects. Now when I'm inside Final Cut and doing motion tricks for my footage a warning keeps popping up saying "RT EXTREME HAS DETERMINED THESE DROPPED FRAMES WERE CAUSED BY SLOW DISK. PLEASE TRY:
-INCREASE THE SPEED OF YOUR DISK
-DECREASE THE NUMBER OF RT LAYERS
-LIMITING YOUR RT BANDWIDTH IN USER PREFERENCES
I don't know how to do any of those things above. Now I checked the user preferences and I couldn't find the "RT bandwidth" option to change. How do you change the disk speed or decrease the RT layers??
Sorry if this is common knowledge. I'm still new with this software.kdjc95 wrote:

Sounds like what I just went through,
wound up at OWC (as usual) 2 drive 800 FW case was $119
Mercury Elite Pro
just remember that if you raid, the drives should be as close to identical as possible.
i believe this is correct:
usb 2 = 480 mbps
fw 400 = 400 mbps
fw 800 = 800 mbps
that just means usb 2 & fw 4 are about the same, but fw 8 is faster / better for video.
Yeah I was looking at that one right after I posted. That's my #1 pick so far. You have an imac? -
[SOLVED] Grub Error "Read or write outside of disk hd0"
Trying to install Arch Linux (as per client request) on an old Seagate Mirra Personal Server. I reflashed the bios to get rid of the Seagate modified ROM and put the standard, stock, VIA bios image on there. Everything boots fine, it boots windows fine. But when I install Arch Linux on the drive and try to boot, it errors out with
Booting...
GRUB Loading.
Welcome to GRUB!
error: attempt to read or write outside of disk 'hd0'.
Entering rescue mode...
grub rescue>
When I ran grub-install and grub-mkconfig during installation neither reported errors or warnings. I'm open to ideas but I need to fix this sooner rather later as this is for a client. A forum thread I found in regards to Ubuntu and grub error 18 said to run:
apt-get remove linux-server
apt-get install linux-386
under Ubuntu and then it would boot. I know Arch removed i386 support a few months ago but im finding it hard to believe that the error above is because of an architecture mismatch. Also I didnt think the CPU in this thing was that old. Hardware Info from the arch live cd says
CPU Vendor: Centaur
CPU Model: VIA Nehemiah
1 core, 64k L2 Cache, 32bit
the Mirra is from 2007 or so, so I expected i686 Arch to be just fine for it.
Ideas???
EDIT:
Wikipedia's Article: https://en.wikipedia.org/wiki/VIA_C3
States: "Additionally, it implemented the cmov instruction, making it a 686-class processor"
So it shouldn't be an issue of i386 vs i686, right?
Last edited by FathisAeril (2013-04-26 21:46:11)Good morning to all of You.
Sorry for posting in a [SOLVED] thread but I find the info that I am about to add relevant and I am betting my vital organs that someone else might find it interesting too.
I did an upgrade last night on my Thinkpad 600E. I was not upgrading it for several days (2 weeks tops) as I lost my USB wifi card and had no internet access on this particular machine. So...
As always before upgrade I checked my rss reader for news and sure enough there was a very informative post from Allan (thanks Dude btw.) in there:
https://www.archlinux.org/news/binaries … ervention/
I did as I was told and upgraded in the indicated way. All was peachy till I rebooted to get new kernel to load. I was met with the mentioned error:
error: attempt to read or write outside of disk 'hd0'.
but the second part was slightly different.
Error: You need to load kernel first
SO since the error was different why am I posting here? Because even after Googling the whole error message this post was the first to come up in my search results so I am betting others will get here as well.
Solution? After an hour or so of fighting (I tried booting up from the Arch CD and fscking partitions, reinstalling / reconfiguring grub, downgrading grub-bios and grub-common packages and many many other things) I finally rebooted to the Arch cd, chrooted (for all those that do not know what that means I would like to recommend this link as chrooting is explained in it https://wiki.archlinux.org/index.php/Be … %27_Guide) to the installation and I have reinstalled the linux (kernel) package and redid the image with the:
mkinitcpio -p linux
and rebooted. Turns out that did the trick. Apparently something went wrong during the kernel upgrade. Possibly due to the changes explained in Allan's article. Reinstalling kernel / recreating image did the trick for me.
So if You are still wondering what am I doing here and why am I replying in this thread - the answer is - 99% search results from Google suggests that this error means incompatibility between bios and the hard drive AND there is nothing really out there that I found helpful in this case. I mean it could not be a bios / hdd incompatibility. This drive has been used in this machine for few years and it was running Arch since November 2012... so this just could not be the case. I am just giving a shout to all those that will get this error that there is another option too.
Kind regards. Thanks for reading. My apologies again for sticking my nose in.
Andrzej
Edit: Few months later the same error - fix does not work... Trying to figure it out...

Check write privileges on disk error
I'm just trying to load the trial version of Acrobat XI on my windows 7 pc. I have plenty of disk space (20 Gig available) and after it extracts the files I get an error that says to check the write privileges on disk and that there might be insufficient disk space. I have checked what I think are the "write privileges" and everything is set to "allow" and I think I have enough disk space. Anyone know how to fix this so I can install the program?
Typically you need to be sure you are logged in as the administrator and have anti-virus disabled. Some of the files of the install go into folders that may be giving you this error and you need to have the proper access to those folders.

Can Time Machine write to a Disk Image on a Time Capsule?
I just inherited a Gen 1 Time Machine (500gb). I have three Macs on my network. In my current set up I have an external 500gb drive split into three equal partitions, one for each Mac.
I know I cannot partition the TC HD, but I also know I can create one or more Disk Images.
Question: Can Time Machine write to a Disk Image on a Time Capsule?
Thanks.
MotionManI know the backups will not mix.
One of the Macs is a MacBook that only hooks up to the network every couple weeks. Before I partitioned my existing TM backup disk, the TM backups of the other two Macs were filling the disk. When the MacBook then tried to make a backup, the oldest backups of the MacBook would drop off.
So, the other two Macs had backps for months, but the MacBook ended up with much less. That is what lead me to the 3 partitions, so each Mac had an equal space for their backups.
Odd that there there is no good solution for this.

FileVault 2 and disk speed tests
A curious thing. I have had FileVault 2 enabled on my MacBook Air (late 2010) and have been running regular disk speed tests using Blackmagic.
This week I bought a new 2GHz Air with 256GB disk and ran Blackmagic, which showed impressive 453/404 MB/s speeds. All well and good. Then I switched on FileVault 2 and decided to repeat the test to see if there was any speed degredation as a result of the encryption. Now I get an error message that the Air's disk is "read only" and Blacmagic cannot run. If I had had problems on the old Air I would have assumed FV2 was the culprit. Anyone have an idea what is behind this?Hi, thanks. BlackMagic is in the Apple App Store. Strange thing is, I could test the speed of the SSD on the 2010 Air while FileVault 2 was switched on. I presumed, therefore, that it was compatible with FV.

Hi All,
My mac mini is now equipped with WD 500GB 5400RPM(WD5000BEVT). After a clean install, AJA test reports >70MB/s for read and write, but now after 9 months with 250GB data, the disk speed degrades to ~56MB/s for read and write. Is this disk degradation inevitable? Or my disk is gonna die?
Thank YouThis is normal. When a disk is empty it is writing to the outside edge of the disk. as it fills up it gets closer to the inside edge. The inside edge has a data rate of about half of the outside edge.

I just see ok to disconnect and disk mode ?
i just see ok to disconnect and disk mode in my newipod nano how can i make it start???
I have this on mine after I charge the battery, which takes putting it into disk mod as I explained in the other thread "Itunes doesn't recognize my ipod"
I have to reset and it works. It can't be good to be constantly doing this though, I would assume.
I'm really getting ticked at these problems since the upgrade. There are 4 nanos in my house, all bought since Christmas, and I don't think we'll ever be buying another unless apple gets it's act together. -
