Disk Speed Degradation

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 You

This 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.

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:

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.

Virtual RAID Array Migration to Windows Server 2012 R2 Disk offline, Degraded, Detached and split

My Residential server is used as a file and web server, however i also use it for learning so it has grown slow over the last couple of years, i now need to get it working ready for when i go to UNI. I have upgraded from windows server 2012 Standard to windows
server 2012r2 standard, i am on the same server, but have put a SSD as my primary drive(so i still have the old hard drive and can go back to that to get my data)
I have also done a BIOS update, so the logical disks (a 2TB RAID 1 with all my important documents) are not showing up on the RAID Configuration in the BIOS.
By changing settings i have managed to get the array to show up on server manager > File and storage services>Volumes>Storage Pools. however there are a number of exclamation marks shown next to the drive(s)
I read in a Technet
Article that i should "set
the storage pool to read-write "
I did this and then in the storage pool box at the top the exclamation mark says "Warning: Degraded".
In the Virtual Disks box (bottom left) the exclamation mark says "Unknown: Detached" and in the Physical Disks box (bottom right) it says "Warning Split" on the second disk.
I have disconnected all other Hard drives, however if i can't get my documents back will have to go back to windows server 2012. Any ideas would be greatly appreciated.
Michael Booth

Hi,
It seems that the second disk is failed, you need to add a new disk to the storage pool to replace the failed disk.

Working with 30 inches monitors and speed degradation

Hi! I'm working in Windows with a 30 inches monitor, using a Quadro FX 5800 so have a lot of GL power. I observed that there is a significant speed degradation on the refresh rate of mask editing and layer moving when I maximize AE to the 30 inches monito on a resolution of 2560x1600 even when the project I'm working on it is just NTSC, apparently this is cause for the big area on the camera view, if I detach the view from the interface and trim it to the NTSC size, so I do not see any gray space on the sides, the the speed gets much better. It seems that AE is refreshing the whole view, even the gray areas outside of the NTSC size. This looks to me like a bad optimization of the view, I hope to see this better optimized for CS5, and I was able to reproduce this on any machine I tried with a 30 inches monitor.
Thanks

Dear Apple,
Apparently you aren't taking the dual link monitor issue seriously enough. I will therefore not be spending $3000 on your current line of products, but will upgrade my existing MPB. If you want my money, be SURE to support power users who use 30 inch monitors externally (DELL monitors, not Apple's offerings). I bided my time, sure that reports that the dual link adapters (which I shouldn't have to buy anyway, as my monitor has regular DisplayPort on it) was fixed would surface. As they have not, I will not be buying at this time.

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.

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?

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.

WRT160N Download Speed Degrading Drastically

I have a 30Mbps download speed when plugged directly into my modem.
When I go from modem to router and then directly plugged into computer (using ethernet) it degrades to 15 Mbps.
When I swith to wireless and I step about 20 feet from router my speed degrades down to 0.57 Mbps with full signal strength.
My version of firmware is 1.2.11. Here are my settings:
MTU = 50
Beacon = 50
Fragment Threshold = 2304
RTS = 2304
Radio Band = 20 GHZ channel
Standard Channel = set to 11
Network mode is mixed.
Security is a WPA2 / AES
What's wrong with this router that my download speed is degrading so much?

Try the following settings:
# Open up the browser and on the address bar type 192.168.1.1 that will open up the Router setup page.
# Lower the MTU (Maximum Transmission Unit) from 1500 to 1400 or less (usually found on your router's main/ basic setup page).
# Then Click on wireless Tab select Channel Width to 20 MHz only and Channel to 6, 9, and 11.
#Adjust the following advanced wireless settings:
~~ Lower the beacon interval from 100 to 75
~~ Lower the fragmentation threshold from 2346 to 2306
~~ Lower the RTS threshold from 2347 to 2304
Hope this will help you.

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.

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.

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=P2KOAUAqYiw#t=1m41s
http://www.youtube.com/watch?v=uPksGswN8Uk#t=0m18s

Thanks 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 ;-)

Massive Disk Speed Improvement Plan

I am moving forward with a disk storage speed improvement plan using my Dell Precision T5400 workstation as the test bed.
Specifically, my goal is to create a super fast 2 TB drive C: from four OCZ Vertex 3 480GB SATA3 SSD drives in RAID 0 configuration. This will replace an already fast RAID 0 array made from two Western Digital 1TB RE4 drives.
So far I have ordered two of these fast SSD drives, along with what is touted to be a very good value in high performance SATA3 RAID controllers, a Highpoint 2420SGL. I'll get started with this combination and get to know it first as a data drive before trying to make it bootable.
Getting any kind of hard information online about putting SSDs into RAID is a bit like pulling teeth, so I'm not 100% confident that these parts will work perfectly together, but I think the choice of SSD drives is the right one. I had briefly considered a PCIe RevoDrive SSD card made by OCZ, but was just too esoteric... I'm actually getting double the storage this way for the same price, I can swap to a different RAID controller if need be, and these drives can easily be ported to any new workstation I may get in the future.
Notably, some early concerns with using SSD in RAID configurations (and things like TRIM commands) have already been alleviated, as the drives are now quite intelligent in their internal "garbage collection" processes. I've verified this with the engineers at OCZ. They have said that with these modern SSD drives you really don't have to worry about them being special - just use them as you would a normal drive.
Once I get the first two SSDs set up in RAID 0 I'll specifically do some comparisons with saving large files and also using the array as the Photoshop scratch drive, vs. the spinning 1 TB drive I have in that role now.
Assuming all goes well, I'll then add the additional two SSDs to complete the four drive array. After a quick test of that, I'll see if I can restore a Windows System Image backup made from my 2 TB C: (spinning drive) array, which (if it works) will let me hit the ground running using the same exact Windows setup, just faster.
My current C: drive, made from two Western Digital 1 TB RE4 drives, delivers about 210 MB/sec throughput with very large files, with 400 MB/sec bursts with small files (these drives have big caches). Where they fall down dismally (by comparison to SSD) is operations involving seeking... The PassMark advanced "Workstation" benchmark generates random small accesses such as what you might see during real work (and I can hear the drives seeking like crazy) results in a meager 4 MB/sec result.
My current D: drive, a single Hitachi 1 TB spinning drive, clocks in at about 100 MB/sec for large reads/writes.
The SSD array should push the throughput up at least 5x as compared to my current drive C: array, to over 1 GB/sec, but the biggest gain should be with random small accesses (no seek time in an SSD), where I'm hoping to see at leasdt a 25x improvement to over 100 MB/second. That last part is what's going to speed things up from an every day usage perspective.
I imagine that when the dust settles on this build-up, I'll end up pointing virtually everything at drive C:, including the Photoshop scratch file, since it will have such a massively fast access capability. It will be interesting to experiment. I suppose I'll have to come up with some gargantuan panoramas to stitch in order to force Photoshop to go heavily to the scratch drive for testing.
I'll let you all know how it works out, and I'll be sure and do before/after comparisons of real use scenarios (big files in Photoshop, and various other things). Perhaps fully my "real world" results can help others looking to get more Photoshop performance out of their systems understand what SSD can and can't do for them.
I welcome your thoughts and experiences.
-Noel

Not sure who might be following this thread, but I have executed the final phase of this plan, restoring a system backup from my spinning drive array onto the new 4 drive SSD array.
All went off without a hitch, I have my same system configuration including all apps and everything just as it was, except everything is now MUCH faster.
The 4 drive array achieves a staggering 1.74 gigabytes/second sustained throughput rate.
Windows 7 WEI score is 7.9 for the Primary hard disk category.
Windows boots up quickly, everything starts immediately, nothing bogs the system down, and just overall everything feels very fluid and snappy. And there is no seeking noise from the drives.
Regarding what this has done for Photoshop... I've only tested on Photoshop CS6 beta so far today, but everything is incrementally improved. Startup time is faster, things seem more smooth and fluid while editing overall, and a benchmark I created using an action to run a lot of image adjustment operations on a big, multi-layer image ran this long to completion:
When the file is opened from (and the Photoshop scratch file is on) a single spinning disk:
4 minutes 26 seconds (266 seconds)
When the file is opened from (and the scratch file was is on) a fast array of spinning drives:
3 minutes 45 seconds (225 seconds)
When the entire system is run from the SSD array:
2 minutes 31 seconds (151 seconds)
During the action, because so many steps are performed on the big file, Photoshop writes a 30+ gigabyte scratch file on the scratch drive.
Summary
Clearly the very fast disk access markedly improves Photoshop's speed when it uses scratch space.
Plus copying big image files around is virtually instantaneous.
I don't use Bridge myself, but I have noticed that all the image thumbnails (via FastPictureViewer Codec Pack) just show up immediately in Explorer windows and Photoshop File Open/Save dialogs. We can only assume this kind of drive speed would really make Bridge blaze through its operations as well.
Following my footsteps would be expensive, but it can really work.

Are these times slow?

Wait, there's more
But nothing LOOKS funny to me either here. But I tell you, opening a file in OpenOffice or sometimes just typing a URL into Firefox takes 10 times what I think it should. It was faster before, too. Not sure what/when it changed.

DISK SPEED SOLARIS 2.6

Hi ALL
We have just had two new disks added to our sun box!!
Question: Do we neew any paramaters/switches adding anywhere to tell solaris 2.6 which speed to write/read at?
QUESTION: If so what are they and do they differ on solaris 8.
QUESTION: I have also been told (but i think i am being blagged) that if i use longer mount point names such as /user01 this can mean poorer performance?
SORRY ABOUT ALL THE QUESTIONS. BUT ANY HELP WOULD BE GREATLY APPRECIATED

Hi
I've never had to tell Solaris which speed to write/read at. Could you elaborate on this.
As for long mount point names causing poorer performance, I think your being "blagged" :0)

Unchangeable disk speed is set at 1x

I have created a disk image and am going to burn it to DVD using disk utility. However, when I get to the last drop down box (where I can change the disc speed) the box is set at 1x and is greyed so I can not change it. Can I do anything to change the speed or am I stuck here? Why is this optioned greyed out?

Wow, I didn't know that. I kept it at 1x. It burned, then I got a prompt saying it couldn't verify the disk. I went this rout as when I burned direct from iDVD the dvd recorded, but when I played it back in the DVD player, it basically repeatedly stopped, then skipped ahead a few seconds. I read this article:
http://homepage.mac.com/geerlingguy/macsupport/mac_help/pages/0015-burn_idvdother.html
So I gave it a try, made this topic and went ahead by burning the disk image through DU. It was MUCH better. It still repeatedly stops and skips throughout the video. It is a home movie I made in imovie and copied the .mov to idvd then wanted to see on disk. Any suggestions before I try to post a new topic as my origional question was well answered?
Thanks. Apple boards rule!

AEB and disk speed

I just got an AEB last week, really was looking forward to the disk capabilities.
Hooked up a printer, and a drive to the AEB, printer works fine, but the drive is GLACIALLY slow.
I know there have been reports of slow speeds when using wireless and the drives, and that even using the LAN port it will drop down in speed. But my performance is less than 500k/sec consistently.
I tried copying a set of backup files (approx 50gb) and the estimate was 45 hours to complete. I disconnected the drive and connected it directly to my 20" iMac, and it took about 15 minutes.
I have the latest update of 10.4.9, and the only thing I could think of was that maybe it's a problem with the hub maybe.
Can anyone recommend a good Mac friendly hub to use?
Thanks

Well, I've given up using the Airport Express Basestation and having a drive connected to it. It's pretty much useless with the slow speeds you get.
