by - 4 years ago

There are quite a few different types of memory cards on the market and thanks to Lexar and their Professional Workflow series I’m able to test almost all of them now. Today I’m starting off our new memory card reviews by taking a closer look at Kingston’s CompactFlash Ultimate 600x card with a capacity of 64GB. Kingston also offers the CompactFlash Ultimate 600x as a 32GB model for those that don’t need as much storage and would like a lower purchase price.


Professional photographers need Flash memory they can count on for even the most demanding shoots; When every image, every pixel, and every frame counts. A failing or bad memory card could cost you those moments and captures that you simply can’t get back again, so this isn’t a place where you should go for anything but the best. The CompactFlash Ultimate 600x offers a sustained write speed ratings of up to 600 times, hence the name 600x (600 times 150KBps), and it makes it Kingston’s fastest card to support high-end digital cameras and other devices using CompactFlash.


The card is designed to deliver superior results with fast data transfer and support for continuous shooting. The CompactFlash 600x card is rated for fast transfer rates of up to 90MB/sec when reading and writing. Especially the write performance has to be good on a card like this to support those burst shot actions in high resolutions. For added peace of mind, CompactFlash Ultimate comes with a bonus download of the data recovery software from MediaRECOVER. It lets you recover lost or deleted files and restore corrupt files on both Windows or Mac systems.

The CompactFlash Ultimate 600x is also a very economical card thanks to the auto sleep mode where it preserves the system battery life in the camera that you are using it in. The card has an operating temperature of zero to plus 60 degrees Celcius and a storage temperature rating of minus 20 to plus 85 degrees Celcius, allowing you to take your equipment into harsher environments.

Kinston flash memory undergoes the strictest quality controls and every single card is 100 percent tested, allowing you to use the cards with a peace of mind. Kingston further backs this quality with the well-known lifetime warranty. So whether you are capturing and storing high-definition video or high volumes of images in RAW, JPEG, TIFF and other large file formats, the Kingston CompactFlash Ultimate 600x will be a great card.

Two convenience factors added to the Ultimate 600x is the protective plastic case for the memory card as well as the ability to write a few notes on the rear of the card, helping you to keep track of what you’ve got stored on the card.

We can see a few more details we can see a few more details of the memory card on the rear of the package, provided in several languages. The compatible operating systems for the MediaRecovery software are also covered here.

The inside leaflet folds out but doesn’t hold much more information. Other than that, we only find the memory card in its protective casing inside the blister pack.

Testing & Methodology

Test system:

Card Reader


  • AIDA64 Storage Benchmark
  • Anvil’s Storage Utilities
  • AS SSD Benchmark
  • ATTO Benchmark
  • CrystalDiskMark
  • HD Tach

I will be testing the memory cards with my new Lexar Professional Workflow drive hub and card readers, initially empty as I receive them and then fill them with 25%, 50%, and 75% data in order to see how they keep up the performance when they start to get full with data.

I will be using a wide variety of benchmark programs to test both the sequential performance and access times. I’ve purposely left out the random performance tests as they’ll be both slow and irrelevant on this type of storage, but also because the tests can damage the drives severely. They are simply not built nor intended for that kind of usage.

On the following pages, I have included the benchmark screenshots from all fillage tests as well charts with a drive analysis of the results over the different fillage levels.


AIDA64 & HD Tach


AIDA64 is a streamlined Windows diagnostic and benchmarking software for home users. It provides a wide range of features to assist in overclocking, hardware error diagnosis, stress testing, and sensor monitoring.

It has unique capabilities to assess the performance of the processor, system memory, and disk drives and is compatible with most Microsoft Windows operating systems. It also has a disk benchmark tool, and that is the one I’ll be using.

Kingston_Ultimate_600x-Bench-aida suite

The Access time tests are designed to measure the data access performance by reading or writing small 0.5KB data blocks at random locations on the drive surface.

Kingston_Ultimate_600x-Bench-aida write access

HD Tach

HD Tach is a program that tests the sequential read, random access and interface burst speeds of the attached storage device (hard drive, flash drive, removable drive etc.). Drive technologies such as SCSI, IDE/ATA, IEEE 1394, USB, SATA, and RAID are all supported.

Version is sadly the final version and the software has reached its end-of-life support. It’s still a nifty benchmarking tool and it can’t hurt to include it in our tests.

Anvil’s Storage Utilities

Anvil’s Storage Utilities is a new benchmarking utility that we have started using here at eTeknix, it’s completely free to download and has the ability to test mainly hard drives and solid state drives, but also any other form of storage medium that you can throw at it.

As well as testing the drive in a variety of benchmarking tests, it also has a drive endurance test that consistently reads and writes data to the selected medium to give days, months and potentially even years of use in a shorter period of time to see how the drive copes in the longer term.

Drive Performance Analysis

The AS SSD software determines the performance of Solid State Drives (SSD). The tool contains five synthetic and three practice tests. The synthetic tests determine the sequential and random read and write performance of the SSD. These tests are performed without using the operating system caches. In Sequential tests, the program measures the time it takes to read and write a 1 GB file respectively. To give a clearer picture of the drives tested, I’ve chosen to include all tests. Special the copy test is one that I think is relevant on the consumer level as it gives the user a view into one of the operations he’s going to do many times.

The ATTO Disk Benchmark performance measurement tool is compatible with Microsoft Windows. Measure your storage systems performance with various transfer sizes and test lengths for reads and writes. Several options are available to customize your performance measurement including queue depth, overlapped I/O and even a comparison mode with the option to run continuously. Use ATTO Disk Benchmark to test any manufacturers RAID controllers, storage controllers, host adapters, hard drives and SSD drives and notice that ATTO products will consistently provide the highest level of performance to your storage.

Final Thoughts


At the time of writing, the 64GB Kingston CompactFlash Ultimate 600x can be yours for $76.99 through NewEgg, £41.18 through CCL Online, or €60.61 through Geizhals.


The Ultimate 600x is Kingston’s top CompactFlash card that comes with a great 600x speed rating as well as a capacity of up to 64GB, plenty of space and speed for all your digital memories. Whether you shoot high framerate HD videos or burst shoot still photos, you’ll want a great performing storage card to make sure that you capture every pixel and prevent video corruption.

The Ultimate 600x easily does both that and it blasted way past its speed rating in our benchmarks. The card comes with a speed rating of up to 90MB/s, but it had no trouble reaching the 150MB/s read speeds throughout the entire benchmarks. It was also a card that kept the performance up, showing a steady line of performance no matter how full the card was. This is something cheaper NAND products have trouble with and it shows the quality in Kingston’s products.

The included MediaRECOVER software to restore deleted or corrupted files is an added bonus to the already great memory card that comes with a lifetime warranty and Kingston customer support. The price is more than fair with a cost of just £0.64 per GB unformatted storage.


  • Great performance
  • Lifetime warranty
  • Recovery software included

“Kingston created an amazing CompactFlash card with their Ultimate 600x 64GB. It impressed us by blowing way past its official speed ratings.”
