Here's a DriveDx triumph. DriveDx showed my just out of AppleCare iMac with two pre-fail conditions for the hard drive. Made appointment and took it to Genius Bar yesterday. Tech looked at DriveDx and was very impressed. Even though out of warranty - they replaced the drive without question.God knows how many dollars and troubles DriveDx saved me since I had several vital FinalCut projects on it!
I just registered my copy of DriveDx. I want to say thanks for saving me a whole lot of time, expense, and aggravation. I’m trying to keep my 2011 MPB running for as long as I can….or at least until Apple gets their act together and starts making 17” laptops again. My Samsung 840 EVO SSD is aging, and my laptop gets very heavy work, managing networks, and saving the world.Lately, the system has been hanging under heavy load. On a whim, I loaded up DriveDx, which told me there were CRC errors on the SATA cable. A $13 cable later, and I am no longer able to crash the system no matter how hard I try. Drive Dx is well worth the $19.99! Thanks a million!
Speed Test For My Mac
As a photographer, I’m always concerned about drive failure because I know it will happen to all of my drives. What I don’t know is when.DriveDx exposes low-level information of internal sensors, pre-fail indicators and lifetime accumulators of information that have allowed me to anticipate problems before they affect my system. As a result, I sent external drive back to LaCie for exchange under warranty due to anticipated drive failure.
This is one of the best investments you can make in your system. I recommend it highly.

External backup disk will have been gone soon. It's time for NAS server. Thanks for letting me know @BinaryFruit!
A couple of days ago, DriveDx warned me (pre-failing) for one of my external drives. I don't use it any more for backup. After DriveDx warning, drive behaved abnormally, I heard loud clicking noises and I got warnings from OS X as the drive unmounted abnormally while it was not the case.Thanks to DriveDx. Best in its class. Excellent tech support.
DriveDx app warned of pending drive failure before it happened. Nice!!! @binaryfruit
DriveDx just warned of pending drive failure - second time @binaryfruit app has avoided server crash.
Shout out to @BinaryFruit for offering a great product and great service over and beyond what they advertise! DriveDX is an awesome app!
Cheaper and better than it's main OS X competitors. DriveDx has a better GUI layout, clearer presentation of data, and explanations of each of the SMART attributes. Beautiful.
Absolute Must for the OS 'Toolkit'! I was having some serious issues with an SSD hybrid drive on my macbook pro, and well since seagate doesn't support mac, their 'seatools' software was useless (and required) for getting a proper exchange. That one event way more than paid for the price of the software. THIS software generated a report that was acceptable for me to get my exchange, and before the drive died completely. Got my replacement drive and I will most certainly never go back to not having it installed.
Just in Time! I downloaded DriveDx and discovered that the second HDD in my MacbookPro (in the superdive location) was having 'failing warnings', although DiskUtility said the drive was OK. So I decided that I had to replace it. I did that and enclosed the failing disk in an external enclosure to use it some more. A week later I began to have serious issues with the failing disk and ditched it. I am very happy with DriveDx, worth the money on all accounts.
I have a not so supported fusion drive in my Macbook Pro. There has never been any way to see the S.M.A.R.T. status. Decided to give this a try and the first thing that pops up is that my Crucial M4 SSD was close to failure because of a bug in the microcode. I have not tried to use this to look at my USB attached drives, since the only one I have is a small external that I boot from in emergencies. But DriveDx not only clearly sees both drives making up my fusion drive, but it also shows me the status of my 3 eSATA drives.
It's finally great to have something even better than Crystal Disk Info to monitor hard drive life signs.
Arrow PrevArrow NextAdvanced Drive Health Diagnostics
Regular diagnostic tools simply check the built-in S.M.A.R.T. status of the drive, which provides the user with little information about the actual state of the physical drive. As opposed to such tools, DriveDx analyzes the current state of the drive using all the drive health indicators that are most likely to point to a potential drive issue (for instance, SSD wear out / write endurance, I/O errors, pending sectors, reallocated bad sectors, etc). See competitive analysis against several popular products hereDrive Failing (Pre-fail) State Detection
Unlike most other tools, DriveDx detects not only “OK/Verified” and “Failed” drive health states, but also the “Failing (Pre-fail)” drive state. Thanks to that, you will detect problems much earlier than when using any other SMART monitoring utilities. This means that you have more chances to save your critical data before any data loss actually occurs. Learn moreReal-time Drive Health Monitoring
DriveDx runs in the background and periodically performs checks to determine the health of your SSD or HDD. When any issue or problem is found, it alerts you immediately. DriveDx acts as an “early warning system” for pending drive problems. As a result, you have more chances to save your critical data before any data loss actually occurs.Early Warning System
DriveDx features a special multi-tier warning system that will inform the user about deviations from the normal state of drive attributes. It constantly monitors each S.M.A.R.T. attribute (and its change dynamics) and starts continuously warning the user as the drive degrades. On the initial stages of drive degradation, the user will receive notifications of the Warning type, then Failing (means that this drive parameter is in a pre-failure state) and only then Failed. Learn moreDrive Self-tests
DriveDx allows you to start and control diagnostic self-tests of SSD / HDD. The primary goal is to quickly identify if the drive is faulty. Usually self-tests consist of a collection of test routines like electrical and/or mechanical performance tests as well as the read performance test of the drive. Depending on self-test type it does read scan of a small area or the entire media. Learn moreModern SSDs and HDDs Support
When evaluating the state of various drives, DriveDx can use different heuristic algorithms depending on the drive model and even its firmware version. One of the key advantages of the software is that the state of HDD and SSD drives is assessed using different algorithms, since many state indicators of HDD drives are not applicable or make no sense for SSD drives.Automatic E-mail Reports
The user can get problem notifications and drive status reports to email. Reporting can be configured on the basis of various criteria. Thanks to this feature, the user does not need to have physical access to a specific computer all the time, which is especially useful for all kinds of server rooms, data centers, etc.A modern, good-looking and user-friendly interface
DriveDx is one of the first drive diagnostic tools created in the true Mac style. All interface elements are clear and intuitive, so it will only take you a few minutes to learn the basics and start using the program. When a problem is identified, you will see a notification on the desktop and the status bar will show the status of your drives. Learn moreDrive Key Metrics Evaluation
DriveDx calculates various ratings of the current status of key drive characteristics (percent values):- SSD lifetime left indicator (in case of an SSD drive)
Mac Os Disk Benchmark
Thanks to these features, users can now have a fuller and better understanding of the current state of their drive.Drive Free Space Monitoring
Mac OS X and applications might fail due to an inability to allocate storage space. In addition, low disk space might cause disk fragmentation. To avoid data loss and to ensure the continuous functioning of your computer it is important to monitor the amount of available storage space on your drive. DriveDx can automatically monitor free disk space and will alert user immediately if user defined free space threshold exceeded. Learn moreDriveDx will protect you from data loss and downtime!

That second command isn't going to measure the read speed of your disk at all. It's reading from /dev/zero and writing to /dev/null; both are virtual devices. The first command already wrote out a temporary file, so just read from that: For a better view of disk performance, these commands should be run with varying block sizes (bs=) and the results plotted. This is left as an exercise for the reader.

Thanks. The submission had the same command twice, and as it was anonymous, I couldn't contact the poster. I did some Googling and found that second command. It seemed to work for me, but I've changed it in the hint.

The read speed test is flawed as written. Using /dev/zero as dd's input and output file doesn't hit the disk at all and will return ridiculous speeds like 15-20 GB/sec. The proper way to do the read test is to be to dd the tstfile created by the write benchmark into /dev/null (but only after clearing the RAM cache by using the 'purge' command).
This one-liner will test the write speed, clear the cache, properly test the read speed, and then remove tstfile to reclaim disk space:
dd if=/dev/zero bs=1024k of=tstfile count=1024 && purge && dd if=tstfile bs=1024k of=/dev/null count=1024 && rm tstfile

dd if=/dev/zero bs=1024k of=tstfile count=1024 && purge && dd if=tstfile bs=1024k of=/dev/null count=1024 && rm tstfile
Here's what I get using this method (and dividing by 1048576 to get Mb/sec):
Internal laptop hd (7200 rpm, sata): Write=42.99 Mb/sec, Read=38.09 Mb/sec
External G-Raid (esata): Write=134.76 Mb/sec, Read=192.32 Mb/sec
External Seagate hd (laptop drive, USB-2): Write=33.59 Mb/sec, Read=36.38 Mb/sec
External G-Raid (Firewire 800): Write=60.79 Mb/sec, Read=66.17 Mb/sec
Encrypted sparsebundle image on external G-Raid above (esata): Write=68.66 Mb/sec, Read=81.33 Mb/sec

That's not really very fast for Thunderbolt.
I bought a Factory Refurb LaCie Little Big Drive for $229 (LaCie.com), removed the drives and the fan, and replaced the drives with a pair of SSDs. Using RAID0, I get around 450MB/s read and 360MB/s write speeds with every test I've tried. It's much faster than the internal SSD in my 2011 iMac.
Yes, the WD My Book is a bit slower, but it has no fan, which is a big plus. I wonder, though, if I should be getting higher speeds.. Oh, BTW, I'm not using RAID 0. I'm using mine as two 2 TB disks. That cuts the speed in half. I bought a Factory Refurb LaCie Little Big Drive for $229 (LaCie.com), removed the drives and the fan, and replaced the drives with a pair of SSDs.

The freeware Xbench's Disk Test offers a nice method for getting a few different kinds of disk benchmarks.
Disk Speed Test For Mac Os X 10.10
To obtain speed expressed in MB/sec, just append the following string to each one of the commands:
i.e: and No need to google around.
Also keep in mind it's only as fast as your system's slowest bottleneck. I realized this myself when I recently upgraded my internal HDD to SSD. Obviously I didn't do proper research. I got a top of the line model and was expecting super fast speeds around 460MB/s on SATA-III, only to realize that my 2008 MBP only has SATA-I so I get about 120 MB/s.
Probably still faster than HDD, but I never did measure the speed before I upgraded.
You wouldn't save a great deal of money going sata-I or II ssd and this way you are future proof if you'll get a new mac.
That thought had occurred to me too. However if I was going to upgrade my Macbook Pro the new one would probably already have SSD and wouldn't be user-replaceable (like in the new Retina Display version)
…or you can just use a disk benchmarking tool like bonnie, which is available to be installed from MacPorts.
When I tried:
time dd if=/dev/zero bs=1024k of=tstfile count=1024 2>&1 | grep sec | awk '{print 'scale = 2 ; '$(NF-1048576) '}' | bc
I got:
awk: non-terminated string }cale = 2 .. at source line 1
context is
>>> <<<
awk: giving up
source line number 2

That awk line has an extra quote, it appears.
Any way, I found that this works:
time dd if=/dev/zero bs=1024k of=tstfile count=1024 2>&1 | grep sec | awk '{print $1 / 1024 / 1024 / $5, 'MB/sec' }'
You don't need bc at all, awk can do the arithmetic. I am dividing the total bytes by the total seconds and by
By the way, my standard internal drive in my 27' iMac (2.8GHz, a couple of years old) did the writing at 91 MB/sec.
Even better, leave out grep also. Awk can do its own pattern matching:
time dd if=/dev/zero bs=1024k of=tstfile count=1024 2>&1 | awk '/sec/ {print $1 / $5 / 1048576, 'MB/sec' }'
One additional thing that might be worth mentioning..your test file (tstfile) should be larger than the amount of physical ram.
This prevents caching and artificially inflated read speeds. Allow me to demo this on my snazzy new iMac with the PCI-e drive..
The system has 16GB of ram, a 3.5 GHz i7 and 512 GB PCI-e SSD:

~> time dd if=/dev/zero bs=2048k of=tstfile count=1024 2>&1 | awk '/sec/ {print $1 / $5 / 1048576, 'MB/sec' }'

Wow faaaast writes - love this drive..
now check the file size
madht@host (]> 01:20:12
~>ls -al tstfile
-rw-r--r--+ 1 user staff 2147483648 Jan 4 13:30 tstfile
2GB, way less than 16GB.
Now lets Read it back..
madht@host (]> 01:30:19
~> time dd if=tstfile bs=2048k of=/dev/null count=1024 2>&1 | awk '/sec/ {print $1 / $5 / 1048576, 'MB/sec' }'

real 0m0.329s
user 0m0.002s
sys 0m0.329s
Mother of God!! 6.2 GB/sec!!
Hmmm..that can't be right.
So lets try a much larger test file.
NOTE: The file size does not *need* to exceed your total ram, just the amount you have free. If you feel this is a valuable use of your time ;) hint, hint -- then adjust block sizes and counts to just exceed the amount of free memory you have available.
Here Goes with a 16GB file:
madht@host (]> 01:30:44
~> time dd if=/dev/zero bs=2048k of=tstfile count=8192 2>&1 | awk '/sec/ {print $1 / $5 / 1048576, 'MB/sec' }'
728.792 MB/sec
real 0m22.583s
user 0m0.007s
sys 0m5.543s
Still bloody fast writes, yum.
Check the size (I always do)
madht@host (]> 01:42:45
~>ls -al tstfile
-rw-r--r--+ 1 user staff 17179869184 Jan 4 13:42 tstfile
Yep, that one there is a whale that can't be crammed into my ram.
madht@host (]> 01:42:49
~> time dd if=tstfile bs=2048k of=/dev/null count=8192 2>&1 | awk '/sec/ {print $1 / $5 / 1048576, 'MB/sec' }'
779.598 MB/sec
real 0m21.018s
user 0m0.006s
sys 0m4.323s
Aaaah much more like it. And still pretty performant, yo.
One more thing to add and I don't know if was already mentioned or not tl:dr -- this is a sequential test only. iow - this is as fast as it gets and in no way indicative of how your drive performs when ~30-50% of its reads and writes are random - i.e. during regular multi application usage of the OS. ioMeter is the best open source benchmarker out there however they don't fully support OSX, just the worker engine binaries -- so iometer itself would have to run on a separate machine. But it's doable ;)
Would anyone be able to tell me how to use these commands to test my USB 3.0 drives or Thunderbolt drives?
