Kingston HS4 Media Reader and 64GB CF Ultimate 600x CompactFlash Card Review


The CompactFlash memory card was introduced in 1994 and helped the digital camera market grow into a multi-billion dollar industry. Despite being around for 21 years, CompactFlash is still used by Canon and Nikon for as the memory card of choice for their flagship digital cameras. CompactFlash cards might be larger than their SecureDigital counterparts, but they are without a doubt more rugged due to their extra thickness. Since CompactFlash cards are still relevant it should come a s big surprise that Kingston Technology is still coming up with and releasing new CompactFlash cards as well as USB 3.0 media readers to go along with them.

Kingston HS4 All-in-One Memory Card Reader

Kingston announced just last week the release of their 4th generation HS4 All-In-One Media Reader and the expansion of their CompactFlash Ultimate 600x family by adding a larger 64GB capacity card to the lineup. These two parts are all about giving photographers and videographers capture content on a high-end lifetime warrantied memory card and then quickly and painlessly back up and transfer all of that digital data through the SuperSpeed USB 3.0 interface. The Kingston 32GB and 64GB CF Ultimate 600x cards support read and write speeds of up to 90MB/s to support burst mode photography or HD video and the new media reader is more than capable of supporting those speeds.

The USB 3.0 reader measures in at 93.3mm x 52.68mm x 16mm and weighs in at 1.7 ounces (48 grams) thanks to the lightweight white plastic body and gunmetal aluminum top cover.

ASUS USB 3.0 Boost

We tried out the Kingston HS4 All-In-One Media Reader and the 64GB GF Ultimate 600x memory card together on our Intel X99 test platform. Our test system was built around the following hardware:

  • Intel Core i7-5960X Processor
  • ASUS X99 Deluxe Motherboard
  • 16GB Crucial Ballistix Elite DDR4 2666MHz Memory
  • Corsair Hydro Series H105 CPU Water Cooler
  • Gigabyte GeForce GTX 980 Video Card
  • Corsair Neutron XT 240GB SSD
  • Corsair AXi 860 Power Supply
  • Windows 8.1 w/ all available updates


The Kinston CompactFlash Ultimate 600x 64 GB Flash Drive CF/64GB-U3 memory card comes formatted with the FAT32 file system and there was 58.4GB of free space on the card in this format.


The first benchmark test we ran was ATTO and we found that the HS4 memory card reader and CF Ultimate 600X card worked well together and the card hit 117MB/s read and 102MB/s on the 8MB file test. On the smaller 128KB file test we found the performance to be 115MB/s read and 73MB/s write. The 4KB file size performance was 21.5 MB/s read and 2.5 MB/s write, which would make this a horrible primary partition drive, so it’s a good this this is a memory card designed for camera use and not as the primary OS drive in a PC.


CrystalDiskMark v3.0.3 showed the sequential read/write peformance at 117 MB/s read and 99 MB/s write, so this CF memory card certainly exceeds the rated ‘up to 90 MB/s’ speed ratings placed on it by Kingston.

Final Thoughts and Conclusions

The Kingston FCR-HS4 All-In-One Media Reader was found to be speedy compact unit that read everything we threw at it since it fully supports the latest SD card speeds (UHS-I, UHS-II) and CF Type I and II (UDMA 0-7). Since it supports the latest card formats it is a worthy successor to the three previous versions! The Kingston FCR-HS4 runs $26.18 shipped and is backed by a 2-year warranty should anything fail on the reader. Take note that Kingston Technology does upgrade the firmware on their memory card readers when needed, so if you purchase one of these and ever do run into an issue with a card be sure to check and see if an update is available!

The Kingston CF Ultimate 600X 64GB card is basically just a speed bump for the CF Ultimate 600x product lineup, but a much needed one. Our tests found the sequential read/write speeds topped out at 117MB/s read and 102MB/s write, which are both well over the rated 90MB/s speeds. If you are looking for a CompactFlash card with plenty of room for capturing your images and videos it doesn’t look like you can go wrong with this one. The Kingston CompactFlash Ultimate 600x 64GB card runs $96.72 shipped and is backed by a lifetime warranty.
