Bootable Thunderbolt on OSX 10.8



I had to use an external Thunderbolt bootable mac drive for the past 2 weeks and the experience has been great.
If you ever booted off Firewire or USB 2.0, the experience was horrible. You often felt like you were using a 2004 Macbook with a 5400  4800 rpm hard drive. Even USB 3.0 operates fairs very poorly due to random reads/writes. Thunderbolt doesn't seem to have those lag issues and feels nearly native to me.

My early 2012 27" iMac went kaput so it went into service. Before it went in, I cloned the drive to a SSD. While the iMac was in the shop, I booted off the SSD via the Seagate (STAE121) Go-Flex Thunderbolt adapter. I simply plugged the drive into another iMac (and Macbook) and it just worked like usual. No need to install different drivers for different hardware or re-configure anything.

Booting off Thunderbolt is a dream. In fact, running off an external SSD was faster than booting off the normal internal 7200rpm hard drive. Mountain Lion boots in about 10 seconds off Thunderbolt.

Carbon Cloning (ghosting) a Mountain Lion OS with the full Adobe CS 5.5, MS Office, GIT, MySQL suite took less than 10 minutes. My working OS build was approximately 40GB in size so this is pretty fast. I did not suffer any sleep issues or drive disconnecting. The typical usage was 9-10 hours a day.
The only thing that was a slight concern was the Thunderbolt cables warming after extended use.




This is an ideal setup for someone who wants to run different versions of OS and Apps. For example, you can keep up to date with FCP X and have a fast bootable OS with just Final Cut 7 when you need it.

BlacX 5G USB 3.0 Update. Fastest USB 3.0 on a Mac

A few months back, I blogged about the BlacX 5G USB 3.0 dock and it being one of the few USB 3.0-SATA dock device to support UASP (USB Attached SCSI Protocol). UASP is a supercharged version of USB 3.0 with an extra boost of turbo. Anandtech noted that the new 2012 Ivy Bridge Macbooks now supports UASP.

With 10.8.2 update, I decided to follow up by seeing if anything has changed using Samsung 830 SSDs.

Today, I tried USB 3.0 booting from an Samsung 830 SSD and I was floored. 12 second cold boot into Mountain Lion. But most importantly, I was getting Thunderbolt speed in the "real world."


Then I ran some benchmarks.
305 MB/s Write on average and 400 MB/s Read.



Thats right. 300/400 MB/s. I still could not believe it so I booted into a few different installs of Mountain Lion 10.8.2. I even tried another Samsung 830. I ran this test 4-5 times with different configuration to see if there wasn't a fluke.


I discounted BlackMagic's speed test and monitored the Disk I/O the Activity Monitor. As you can see, copying and reading 50GB of tests, you can see it reading 400 MB/second. OK, BlackMagic wasn't acting weird.



I then tried my real world test of copying a 30GB Virtual Image .VMDK file.
A 30 GB ( 29.31 GB VMDK to be exact) took 1.33 seconds to copy.





To do the math. It definitely corroborates the benchmark. According to my calculator, it wrote at 300.56048 MB/second in real time. This is not a synthetic benchmark but what you will actually get in the real world.


After reading all of this and you still don't believe me?
I did a video on my iPhone.

There you have it. This may be the fastest USB 3.0 to SSD adapter setup on a Mac and even PC (unless you have a new rare Gigabyte motherboard with UASP USB 3.0 controllers). These test were done using the Samsung 830 SSDs.

The Blac X 5G is smoking fast with UASP. It appears to have an ASMedia 1051 controller.

Macbook Pro USB 3.0 RAID ZERO with USB sticks


What happens when you try to stripe two USB 3.0 sticks together in a RAID 0 on a 2012 Macbook with USB 3.0 support?


I decided to find out to see if there is any tangible benefit gains.


Here, I have two Patriot Supersonic Xpress 32GB USB 3.0 sticks for my test. I used Disk Utility to make a stripe set and had the set formatted HFS+. I ran Black Magic Disk Speed Test to see the before and after differences.



Single USB stick benchmark.


Striped Zero RAID benchmark.



In short, you will get twice the speed in RAID 0. Pretty cool!

Macbook Pro and 16GB of RAM


I'm going to dispell some myths right now concerning the (non retina) MacBook Pro's maximum RAM upgrade. Apple only officially sells 8GB upgrades.

Since 2011, Sandy Bridge architecture allowed you to install up to 32GB depending on processor. Most of the processors had a max 16GB ram limit. It is supported by Intel's chipset.
Apple does not officially support it as well as many other manufactures. Since there are no dual 32Gb sticks, the most you can install is 16GB (2x 8GB sticks).
This holds true for the Ivy Bridge mid-2012 updates.

I have a mid 2012 i5-3210M MBP 13 running 16GB. The sticks are running DDR3 1600MHz (very fast RAM) and the total cost was $115. My other 16GB sticks running 1333 MHz can be as low as $80 discounted.

I have four or five Virtual Machines running concurrently without a sweat. With my M4 512GB SSD, starting Win8 preview and Win 7 with 4GB each is no problem.

Here are some picture proof. Apple may not officially support and sanction 16GB but it can run.

2012 Ivy Bridge MacBook Pro 13 short review

With the retina 15" Macbook Pro stealing the show, the best selling MacBook Pro 13 gets very little fanfare. In fact, there are not many reviews on the net for the new Ivy Bridge refresh. It isn't as exciting as newer laptops on the market and the resolution of 1280x800 is very dated with newer machines now sporting full HD. However, if you are a mac user, this machine is still a viable option for those who prefer the OS X operating system.

Frys recently advertised the 2.5ghz i5-3210M, 4GB Ram, 500GB 5400 rpm hard drive model for $999. This may have been a price mistake but nonetheless, I had Best Buy price matched it. I had about $900 in Best Buy gift certificates and $115 out of pocket, I got myself a new 2012 MBP 13. I already have extras SSD, extra 2.5 drives and memory lying around so I chose the MBP 13 over the Air due to expandability reasons. I now have MBP13 with dual drives (512GB SSD and 7200 rpm Seagate hybrid HDD in cd bay) and 16GB of RAM. No Air can match this. This will be my secondary Mac while I wait for a corporate issue Retina MBP 15 to arrive.

Here is my take on the new device. This machine is a nice welcome upgrade. I'm going to mostly cover expandability/upgrade and the new USB 3.0 performance.  This post might come in handy for those considering 3rd party upgrades for the Macbook Pros.

First of all, I want to comment that Apple has excellent packaging. Compared to my Dells and Thinkpads, no one comes close in terms of packaging. Opening the box, you get a very good first impression. Not that it matters for geeks like us but I did take note.


Compared to previous MBP 13, the only noticeable exterior change are the Thunderbolt port and the new USB 3.0. Otherwise, it looks exactly the same as the previous models.




And pictured below is the reason why I would get an MBP 13 over an comparable Air. Expandability.


Opening the interior, you can see the precision engineering Apple puts into its products. The interior is a fine piece of industrial design.  This corroborates what I've said earlier, Apple takes packaging very seriously and the quality shows. The interior is tight and I can see why Apple decided to go soldered ram/daughter card on the new Retina Macbook Pro. You can't get any smaller with off-the-shelf components.

I replaced the CD burner and place an SSD into the bay. You can get cheap adapters on ebay or use something like the OWC data-doubler pictured below. With every Macbook I've owned, I usually toss out the CD burner for a second drive.



I'm not going to go into CPU and graphics benchmarks because I'm not qualified to do so.With Google, you can probably find reviews of the i5-3210M and geek bench scores online. Coming from a Core Duo 2.5 (circa 2009), this machine is almost two times faster. 

Most important for me is disk I/O. Everything about it is better. SATA 6 all the way (even the CD bay is SATA 6), UHS-1 SD card reader, Thunderbolt, and USB 3.0. I'm going to be using this machine for Lightroom photos, minor final cut editing and managing my 500GB or so music library. I'm usually backing up and copying hundred of gigs worth of data so the fast I/O is important to me. 

Lets get started with my review.

I got a Crucial M4 512GB SSD as my OS drive. Street price is roughly $350 if you know where to look. You can't get this price and performance in any Apple upgrade. I also have a 7200 rpm HDD in the main drive.

Internal Storage Speeds.

The SSD produces an average 512 MB/s read and 250 MB/s writes. This is smoking fast.
Boot times takes less than 8 seconds. Photoshop CS5 and Lightroom starts up in less than 2 seconds. Cycling through 100 20MB Raw Image files is buttery smooth. Again, CPU processing doesn't matter for my needs but with fast I/O, you can clearly see the benefits. Couple with 16GB of RAM, I can now open 5-10 Gigabyte TIFF files with ease that even my old Mac Pro struggles with.


Now for the Seagate Hybrid 750 Momentus XT hard drive. This is a 7200 rpm Hybrid drive with a 32MB SSD cache. Retail is $179 but if you hang out on slick deals and discount forums, you can find them for $80 street price if you know where to look. If I didn't have a few SSDs lying around, I'd probably use this as my primary drive. It is probably overkill for my needs as it is mostly for storing music and videos. 

When you are used to SSD, HDD benchmarks aren't so impressive any more. Still, this clocks better than 80% of the users out there still using 5400/7200 rpm drives. It clocks in at 108 MB/s read and 104 MB/s writes. My old 2009 Macbook with a 7200 rpm drive and SATA (1 or 3) interface could only muster 80MB/s.




External Drive Speeds

Now for the external drive speed observations. How does USB 3 fare? Well, I decided to find out using a Crucial M4 128GB SSD w/ SATA 6. I've tested this drive and normally get 500MB/s reads when plugged in internally. I am also using another Seagate Momentus HDD for the external HDD comparison. All the devices will be connected via Go Flex SATA controller adapters.

Seagate Go Flex drives comes with a variety of SATA adapters including esata and pricey Thunderbolt. I have a few of their adapters - USB2, USB3, and FireWire800.

It is not going to be an accurate comparison because each controller have different characteristics. It is also hard to know which brand of USB2/USB3 controller is the fastest. However, I think this is going to be fair comparison since all the controllers are made by Seagate. I will do a review of the Seagate Go Flex devices in another post. If I can pony up the money, I will also follow up with a Thunderbolt adapter review. After reading many reviews on the Thunderbolt to SSD benchmarks and comparing with my own USB3 benchmarks, I may just stick with USB 3.



Here it is in action. 


USB 3.0

I have to say, I was a big fan of Firewire 800 for years. Before eSata, I only used Firewire 800 due to its inherit advantages over USB 2.0. With the arrival of Thunderbolt, I was hoping manufactures would come up with Thunderbolt docks and enclosures. That hasn't happen yet. USB 3.0 is the most economical external I/O connection. In my general use, it is by far faster than USB 2 and Firewire.

From the screen grabs below, we have 204.4 MB/s read and 152 MB/s reads. This is fast but not as fast as native SATA 6. You also have to remember this is USB 3 connected to a fast SSD. 


USB 3 to HDD won't get these speeds. Also, USB 3 to HDD is very close to Firewire 800 to HDD that I think it is a toss up. So if you are using a portable drive enclosure, your usage may vary.

Here is is with a HDD. 90MB/s and 83MB/s write and reads.





Firewire 800

As you can see in the following screenshot, there is no real benefit to connect a SSD to a Firewire 800 controller or enclosure. You will get the same speed as you would connecting Firewire 800 to a 7200 rpm hard drive.

73-80 MB/s read is typical of what you get from Firewire 800. I've seen  Firewire 800 go up to 80-90 on some high-end controllers but I wanted to stick to using Seagate GoFlex adapters for these tests. Using different controllers, you can get the same speed as the USB 3.0 to HDD I pictured above.




USB 2.0

Like Firewire 800, there is no advantage to connecting a SSD to USB 2.0
38 MB/s read and write is on the very high end of USB 2.0's bandwidth threshold.



So what do these benchmarks tell us?

For mac users, USB 3.0 is a very cost effective and fast I/O. Thunderbolt's advantage that I've seen only comes when you have fast RAID setups. The SSD-Thunderbolt reviews I've seen on the net are in the high 200 MB/s. ESATA still rules for external I/O. Unfortunately, there is no ESATA on macs and it is harder to come by even on PC. I've even had problems with ESATA on my Thinkpad with drop-off and connectivity issues.

If you are using HDD (standard platter based hard drives), Firewire 800 is still a good platform. If you are like me, I would not rush to dump your existing legacy Firewire 800 for new USB 3.0 drives yet. Those docks, enclosures are still good for standard platter drives.

About these benchmarks, I have the luxury of having 4-5 fast SATA 6 SSDs lying around and it is great to see 200+ MB/s speeds. However, for the majority of people, HDD is still a way more cost effective solution. You can pick up 1TB drives for $80 versus $120 for 128GB SSD.

Going forward, I will be investing in USB 3.0 for future proofing.

UHS1 SD Card Reader

Now for the SD card reader. As most photographers know, built in SD card readers on laptops are woefully slow. Most people I know get expresscard/PCMCIA adapters to get a fast SDcard reader. I had to do the same thing for my Thinkpad T420 because the the SDcard reader was so slow.

The MacBook Pro since 2011 now have UHS-1 (Ultra High Speed) readers. If you have a UHS1 card, expect a pleasant surprise. Using a SanDisk Extreme 45 (rated at 45MB/s), I got the rated speed of 45MB/s of my card. I wish I had a 90MB card to compare but I don't.

As you can see by the screen grab, it reads as fast as the card and you don't need to invest $30-40 for a new high speed reader. It is faster than many USB 2/USB 3 sd card readers.

As for the writes, I assume that is the limitation of the card or formatting of the card as FAT32 which causes problems for mac based disk benchmarks. Furthermore, I hardly ever write to SD as I am usually reading files that have been written by my camera.




In conclusion, the MackBook Pro 13" Mid 2012 Ivy Bridge is a great machine. The I/O improvements are very tangible for a mac users who want a portable lower price macbook. The expandability of this machine is more attractive to me than the portability form factor of ultrabooks or Airs. 16GB RAM is my minimum requirements and this book is capable of it. The only drawback is the 1280x800 screen resolution. It is very antiquated. I don't mind so much because I will mostly be docked into a WQHD Cinema  Display 90% of the time.  As I said before in another post, anything is better than 1336x768. 768 resolution doesn't cut it for me.

Now, I can't wait for my Retina MBP 15 to arrive to compare this with.

Apple's unique hardware feature: Target Disk Mode


One of the best feature of Apple hardware is Target Disk Mode. The icons you see below indicates that this particular mac is now an external hard disk.


Apple has had some pretty cool hardware innovations throughout the years/decades.For example, in 1987,  the Macintosh II was the first personal computer to support dual/multi-monitor displays. Since the early nineties, Apple computers had auto-sensing, auto switching ethernet ports that allowed you to connect computers together without a hub or cross-over cable. These technologies are now taken for granted and are available for Windows and Linux users. However, Apple is the only computer brand of hardware that has the nifty feature called Target Disk Mode.

With a keyboard combo press at boot, you can turn your macbook, mac mini, imac, or mac pro into a bootable, external hard drive. The "target" computer will be seen as a portable hard drive by another computer. This is a very unique feature of Apple hardware. In fact, many of my friends and colleagues do not know this even exist.

You can use this to clone and deploy software builds. You can use to trouble shoot hardware defects of the target computer. I remember when the very first iPod came out, we deployed software builds with a 12" powerbook and an iPod 5GB using Target Disk Mode. All the Mac Workstations were built, clone and restored in less than 10 minutes. Firewire back in those days was light years ahead of USB 1.0.

Target Disk Mode now supports thunderbolt so you can shuttle large files quickly from mac to mac. For example, I know people who take their SSD powered Macbook Air on photo and video shoots. They create gigabytes of footage and proof their work remotely. When they get to the office, they target mode their Air's to their main Mac Pro workstations. They get 300 Mb/s transfer speed over Thunderbolt and it is 10-20 times faster than conventional firewire/usb. As you can see, there are many numerous usage for Target Disk Mode.



Today, I used Target Disk Mode to clone the factory fresh drive of a 2012 Macbook Pro 13" 5400 rpm drive to a 512GB Sata 6 SSD drive. There is no need to remove the internal drive. There is no need for a bootable USB stick to run a cloning software like Clonezilla.

Maybe someday, other platforms will have this unique and neat feature.
