With Speedmark 7 development behind us, Macworld Lab can once again focus on other Mac-related performance stories. On the top of the list of projects is a follow-up on previous Thunderbolt performance stories (Thunderbolt versus FireWire and USB 2.0, Target Disk Mode and more). This time around, we look at Lion versus Snow Leopard performance, MacBook Air performance, and update our eSATA comparison results using a 6Gbps ExpressCard from StarTech.

In our testing, we used the Thunderbolt-equipped Promise Pegasus R6. We also used a Promise SmartStor DS4600. (We don’t have access to a non-Thunderbolt to an array that’s similar to the R6.)

Snow Leopard versus Lion

Our first few lab reports on Thunderbolt were done before Lion was released. Now that Lion has been released upon the Mac world, we ran tests to see if the operating system affects performance. We tested a Thunderbolt-equipped 17-inch MacBook Pro with a 256GB SSD with Snow Leopard and then with Lion.

Performance wasn’t affected much by the new operating system. Each of our six tasks were a megabyte or two per second slower under Lion when testing eSATA speeds. Results were mixed on the Thunderbolt tests, though, with half of the tests (AJA System Test read, 2GB file read and write) speeding up under Lion and the half of the test slowing down a bit.

Overall, I’d say its a wash, with the average Thunderbolt file transfer speeds being less than one percent slower on Lion than on Snow Leopard, while AJA Read tests were 7 percent faster on Lion and AJA Write tests were 9 percent faster on Snow Leopard.

AJA System Test is included in retail software downloads for KONA, Io and T-TAP products, and is used throughout the industry to provide accurate and detailed evaluations of drive performance statistics. This information allows users to predict the capabilities of any drive system for recording and playing back various resolutions and codecs.

MacBook Air vs. 17-inch MacBook Pro

It hardly seems fair pitting the diminutive MacBook Air up against Apple’s largest laptop, but it turns out that the speedy flash storage in the Air helped it take top honors in three of the six tests. The average file and folder transfer speeds were almost identical between the two, as was the AJA System Test Read scores. The AJA write tests were 6 percent faster on the Air.

eSATA 6Gbps vs. Thunderbolt

We received a 2-port 6Gbps ExpressCard eSATA Controller Card from StarTech and tested it with our 17-inch MacBook Pro and the Promise SmartStor SD4600. Compared to the results of a 3Gbps Apricorn eSATA ExpressCard, the Promise SmartStor DS4600 using the 6Gbps card was nearly twice as fast in the AJA System Test read scores and 33 percent faster in the AJA write test. In our files and folders transfer tests, the 6Gbps card was 44 percent faster reading a 2GB file, 30 percent faster reading a 2GB folder, 34 percent faster writing a 2GB file and 24 percent faster reading a 2GB folder.

These faster speeds also closed the performance gap between eSATA and Thunderbolt, though many tests were still much faster with Thunderbolt. For example, Thunderbolt was still 2.5 times faster reading and 5.5 times faster writing than eSATA 6Gbps in our AJA System Test. In our files and folders transfer tests, writing is still considerably faster on Thunderbolt, with 74 percent faster file writing and 59 percent folder writing times. Our read speed results were much closer with the Thunderbolt drive being a little more than 2 percent faster than eSATA in our file transfer and eSATA actually finishing the folder read test nearly 4 percent faster than Thunderbolt.

The drives we tested with are not identical, but they’re as close as we can get with the hardware we have on hand.

Enables you to verify the performance level of any of your drives in order to let you know if each device is tuned to provide the best results

AJA System Test is designed to measure the input and output performance of your volumes, and it works by writing a certain amount of data while measuring how long it takes to read and transfer the info to your storage device, to your RAM or to a KONA Video capture card.

Capable of testing both local drives, as well as all drives accessible over the local area network

Furthermore, the AJA System Test utility offers you the possibility to tune your tests by changing the amount of data that will be processed during a test (goes from 128MB to 16 GB) and the video frame size (the amount of data that will be processed in each transaction).

Also worth noting is the fact that AJA System Test automatically detects all connected volumes and you can select the one you want to perform your tests on from the Volume drop down menu.

Moreover, if you want to test network volumes, you must check the appropriate box in the Preferences window.

Makes it possible to run multiple types of drive performance tests

AJA System Test provides six types of performance tests: Disk Read/Write, Disk Read Existing File, Sweep Video Frame Sizes, Sweep Binary Frame Sizes, Sweep File Sizes and KONA DMA (requires a Kona card and to have the driver software installed).

Additionally, while using AJA System Test to test a drive, you should disable the file system cache to make sure that it does not interfere with the test readings.

Powerful yet easy to use hard drive read/write performance testing tool for macOS

Thus, by clicking the Graph button you will be able to visualize the test results in the drawer panel (you can also choose to view them in text form).

On the whole, AJA System Test is a simple to use macOS utility which will allow you to run performance tests on the storage drives connected to your Mac and determine if they work properly.
