G710 hard drive read/write speed

Hello,
I have a brand new Ideapad G710 with 1TB Serial ATA 2, 5400rpm with advertised speed of 3 Gb/s (= 384MB/s).
I am running Windows 7 ultimate x64 with SP1.
When I test hard drive read/write speed (I used CrystalDiskMark) I get results of about 100MB/s, which is 3-4 times slower than it should be.
I am not running any resource heavy applications (Resource monitor reports Disk I/O to be 0 most of the time in idle state). I have 3 partitions, each with 16-32GB paging file size and all are >90% empty. All partitions have been defragmented before testing.
Is this normal? Are there any lenovo drivers or utilities than I might be missing or that can slow/speed this?
Solved!

hi Daew,
Welcome to the Lenovo Forums.
The results that you got while running CrystalDiskMark is normal. The SATA 2 (3Gb/s) that you mentioned is actually the SATA interface support, not the actual read/write performance.
If you have a Seagate HDD (eg. ST10000LM024), check these specs
From the above specs, the unit has a cache that has a read/write max speed of 145 MB/s but there are environmental factors and power requirements to get this speed (eg. read/write speed on AC power is differente from battery power).
AFAIK, if this is the specs that is design for this drive, there's no way to speed it up.
If you're planning to upgrade in the future though, you can get an SSD for faster read/write.

Hard drive read write speeds are too slow

I was having an issue with 17inch macbook pro. was getting 4.0mb/s read write speed tops. and smart status failure.
So i replaced the drive. The new drive is a 7200 RPM 500GB WD drive. I'm getting 12.0mb/s on top speed. Computer feels a little quicker but still slow overall.
I ran this test on a fresh install of snow leopard.
Is it just me or do those read/write speeds on the new drive still seem slow?

That does seem slow - on the other hand, what are you using to measure it?

Thunderbolt drive Read/Write speeds have significantly dropped

I got a new Western Digital Thunderbolt VelociRaptor drive. When I did speed tests on it using "BlackmagicDesign" Speed Test software initially (when empty) the drive was giving me read and write speeds of 350 MB/s. Now however I have 90% of the drive occupied with data and the read/write speeds have dropped significantly to 230 MB/s. Any ideas as to why and how I could improve this?
Thanks

Welcome to Apple's discussion groups.
Apple's AirPort base stations aren't known for fast file serving, but for most purposed they're fast enough.
I can't comment specifically on your Aperture plan, but with some software it's important to avoid simultaneous access by more than one user.

Usb hard drive - slow write speed

Hey all you mac savvy people out in mac land.
I got the airport extreme n edition for christmas and I set the thing up at the 5Ghz N speed (300Mbps) and all is happy. then I connected my external usb 2.0 hard drive to begin using that as a network storage, the airport picks it up and sees it, and I can read/write to it. When I read from it, it reads really fast at about 6 MBps (i can see this speed by using the iStat widget) but the write speed to it is about 2 MBps (again, through iStat). I know that the hard drive itself is not slow because hard wired to it is really fast and i know that the airport extreme is fast for transfers because i transfer about 12-13 MBps to my pc. Why is it that the write speed going wireless to it is slow? any ideas?

Make external hard drive read/write

Not quite sure if there is in the right section but oh well.
Here's the story:
SeaGate FreeAgent GoFlex Drive (1.5TB) (THE FOLLOWING INFO WAS TAKEN FROM ITS APPLICATION: ("SEAGATE DRIVE SETTINGS")
Drive Info
Model: FA GoFlex Desk
Firmware: 0D19
Volume Info
Format: Windows NT Filesystem
Capacity: 1397.26 GB
Available: 1224.35 GB
Used: 172.91 GB
Mount point: /Volumes/FreeAgent GoFlex Drive
So it seems to slow down my iMac (10.6.8), 2GHz Intel Core 2 Duo, 1.5GB 667 MHz DDR2 SDRAM (memory) (1st Generation 17 inch) a fair bit. Could this be because of the Format? I have no idea why it says that. When I first installed it, it asked what OS I'm going to use it for. Not quite sure if I chose both or just Mac. But those files have somehow dissappeared.
Now in Disk Utility...the RAID tab, Format says it is set to Mac OS Extended (Journaled) but then in the Erase tab it says Format: Windows NT Filesystem
Which format is it set to!?!?!?!?!?!?!
Now to the main point:
I also have a new 13" MacBook Pro. When I plug it into it, I only have Read Permissions. How do I make it have Write Permissions as well?
Sorry for the long essay...I hope you can help me. I might have two problems here.
1. Is the format correctly set up for my iMac?
2. How do I set it to have Read/Write permissions on different computers?
Thanks.

The Format is incorrect for Mac use, as you guessed. Go into Disk Utility again, highlight the external har drive in the left hamd column by clicking on it and select the "Erase" tab, up and over to the right. Then select the Format below that will be installed as "Mac OS Extended (Journeled)". THEN, OK the erasure. That should clear things up.
Note: your Windows PC will NO LONGER be able to read the external hard drive. It will be formatted for OS X use.
Hope this helps

Hard drive read/write problems

I have three external hard drives connected to my iMac that are always on with the computer. Just recently, I started having trouble with permissions. Every day I have to go into disk utility and click "verify disk" to be able to write to the drive, if I don't do that then I can only read the drive. It's the same with all three of them! This just started a couple of weeks ago. What is wrong?
Oh! My recollection recalls that a couple of weeks ago upon starting the iMac one morning, one of my hard drive's name, as well as a .iso file that I have on my desktop, were totally wacko. Full of numbers and characters, etc. I'm wondering if my HD problem is caused from this?
I desperately need some help!

if running "verify disk" helps at all it's definitely not a permissions problem. it's a file system problem. when system detects a serious file system problem when mounting an external drive it will mount it as a read only file system. run "repair disk", not "verify disk" using disk utility on all the drives involved. see if that helps. and are there any errors when you run it?

Hard drive read/write question

Hi,
I purchased this mac pro(2008) with the stock seagate 320gb hard drive (model ST3320820AS_P) and I am interested to know what kind of read write numbers to expect from this drive.
I am having a tough time trying to find any numbers that aren't in reference to RAID setups, and became concerned that this drive might be working at peak performance due to firmware issues others are talking about.
(tangent - I would like to add more drives, but am on the fence for WD or seagate)

I saw some systems came with WD 320GB. Guess Apple is using both for now.

Mac Pro - Boot drive - Read & Write speed differences

Hi
My Mac Pro came with a 500GB boot drive when I ordered it 3 years ago. It has been used most days and now runs
Snow Leopard (for scanners and a canopus video box that don't work with Lion) and Lion.
I did a write & write test on the drive recently at both were approx 60 - 65 MB/s. I have another drive in my machine
I bought last month, replacing an WD drive that failed in less than 18 months. This new drive (complete same as replacement
is a WD Caviar (Black) 1TB 64Mb drive.
This drive tests at speeds for 110MB/s. This may seem an obvious question, but will I notice much difference if I swap the drives
around and have the newer drive as my boot drive.
Also, does having two OS on a HD slow the drive down also?
Thanks in advance
Matt

Use the 500 for a system backup clone then.
If you want to and have $150 then I recommend this for the system actually (you don't need 1TB and even if you did use a 1TB which are now $120, I would 'short stroke' and use just 1/3 to 1/2 for the system anyway.

[SOLVED] Log hard drive read/writes

Is it possible to monitor everytime a file on the hard drive is read from or written to and to add that information to a log?
Last edited by Chris Denton (2010-07-25 10:32:57)

Thanks. That seems to be working quite well.
One problem though, I notice I have to exclude /dev (otherwise it seems to get stuck in a loop like fukawi2 mentioned). This does raise a question though, I notice that it isn't actually accessing the physical disk when this happens, so I wonder, is there a way to tell it to only include events that occur on the disk?

Read/Write speeds with Airport Extreme and USB Hard Drives

Anybody know how fast the read/write speeds are with a USB hard drive and the Airport Extreme Base Station?
My Setup
I have a 17 MBP (2010) and a 13 MBP (2011) - no SSD's
MBP generally connect via 802.11n 5Ghz with a very strong signal
Gigabit connection on a Windows Desktop
I have a variety of external drives (7200, 5400, Drobo) at varying capacity (320GB, 2TB, 5.6TB)
Goals
Backup: Time machine
Backup: File copies of pictures and home videos (greater than 1GB files)
Backup: Crashplan
File sharing: Aperture libraries--not sure if that is possible or practical. That is something that I need to research further...but on the off chance people have experience with it.
Thanks!

Required read write speeds

hey
i'm currently in the process of building a NAS and have been previously working with a firewire hard drive box..
my question is simple (at least i think so).....what are speeds that are typically seen when editing with firewire boxes....i was using a 800 firewire box and i know real world situations you don't get 800 mb/s....
i edit HD footage (captured AIC 1080i @ 60fps) and this new NAS box that i'm building says it can achieve anywhere between 22-45mb/s read/write speeds
will this be fast enough?
thanks for your time guys!
Thanks
~Will-i-am~

it can achieve anywhere between 22-45mb/s read/write speeds
will this be fast enough?
If all you deal with is DV.

Macbook pro 2011 HD read/write speed

My 2 and half year old macbook pro seemed little slow so i did read/write speed test and it shows about 45MB/sec read/write speed. It is normal for a old 5400rpm hard disk. I have mountain lion.

Yes, that's probably about normal for an older, slow drive.

Macbook Pro 1.1 how to improve read/write speed

Hello,
I am looking to improve the read/write performance of a 2006 2.16 Intel Core Duo Macbook Pro with 2gb RAM (the max), that I use on a specific job in a specific workflow.
In the workflow there are three retouchers using three different MBPs and transferring files via Ethernet network to a fourth MBP (the one in question) which is used as a dropbox, if you like.
So the MBP in question has no applications running. Files are saved to it and opened from it and saved back to it.
How can I improve read/write speed on this MBP under these conditions?
Would installing an SSD be the answer? Or is it really a processor issue and there's nothing to be done? I figure RAM doesn't really come into it, but in any case 2GB is the max this model can accept.
Many thanks in advance.

An SSD would definitely improve read/write speed. However, depending on capacity needed, are you sure you want to sink the money into this machine? Start here:

MacBook Pro (13-inch, Mid 2009) - Maximum internal hard drive size and speed?

What is the maximum size of hard drive and speed for an internal hard drive to my Macbook Pro (13 inch, Mid 2009), please?
I bought myself a Technics 1TB, 7200 rpm internal hardrive. Made a clone successfully in Super Duper.
It fits, but It is not available for starting up my Macbook Pro. Not available in System Prefs, but visible and grey in Disc Utility.
Although it starts up my Mac Pro just fine.. but not my Macbook Pro.
Is there a limit of hard drive specifics?
What is the maximum size of hard drive and speed for an internal hard drive to my Macbook Pro (13 inch, Mid 2009), please?

Thanks for the reply
I cloned the Technics HDD ( 2,5" HGST Travelstar 7K1000 - 1 TB : HTS721010A9E630) from the MBP.
I tried to boot it up with my Technincs ( 2,5" HGST Travelstar 7K1000 - 1 TB : HTS721010A9E630) installed in my MBP (as my internal hard drive).

I am moving from PC to Mac. My PC has two internal drives and I have a 3Tb external. What is best way to move the data from the internal drives to Mac and the best way to make the external drive read write without losing data

Paragon even has non-destriuctive conversion utility if you do want to change drive.
Hard to imagine using 3TB that isn't NTFS. Mac uses GPT for default partition type as well as HFS+
