CF/SD/XQD Performance Database - Continued
Card-to-Computer Transfer Speed: SD/SDHC/SDXC Readers
This page was last updated on April 11, 2011

If you're faced with copying pictures from a stack of SD/SDHC/SDXC cards to a Mac or PC, and time is of the essence, this section of the CF/SD Performance Database is for you. CompactFlash card readers are covered on a separate page.

The Readers

delkin_expressard34_multicard_thumb.jpg Delkin ExpressCard 34 Multi-Card Adapter

This adapter is compatible with computers equipped with ExpressCard 34 and ExpressCard 54 slots, and accepts SD/SDHC plus certain other smaller memory card formats. Once inserted, the ExpressCard 34 Multi-Card Adapter sits flush with the slot opening, which means with some or all ExpressCard-capable laptops it can stay in there all the time. Case in point: it doesn't protrude at all from our MacBook Pro 17 inch test machine, plus it stays in place as cards are inserted and removed.

ExpressCards can be designed to communicate internally with the host via USB 2.0 or PCIe. This adapter appears to use USB 2.0, and delivers read speeds in line with that. This isn't really a hindrance, however, as the current SD/SDHC specification limits card throughput to less than USB 2.0's real world maximum.

The Delkin ExpressCard 34 Multi-Card Adapter is an all-too-rare example of an adapter-style reader that worked seamlessly and without incident during benchmarking here.

griffin_simplifi_thumb.jpg Griffin Simplifi

The Griffin Simplifi combines a USB 2.0 card reader that accepts CompactFlash, SD/SDHC and various other memory card formats, a powered two-port USB 2.0 hub and iPod charging/syncing dock into one trim, well-designed desktop accessory.

It connects to the computer via a detachable cable.

hoodman_raw_usb_thumb.jpg Hoodman RAW UDMA USB 2.0

This CompactFlash and SD/SDHC USB 2.0 reader connects to the computer via a non-detachable cable and is nearly the same in appearance as Hoodman's RAW UDMA FireWire 800 CompactFlash reader.

(It's difficult to see in the picture at left that there is a separate SD/SDHC card slot beneath the larger CompactFlash slot.)

kingston_19in1_thumb.jpgKingston 19-in-1 Media Reader

This USB 2.0 reader, which accepts CompactFlash, SD/SDHC/SDXC and various other memory card formats, connects to the computer via a short, non-detachable cable that's an ideal length for use next to a laptop. An extension cable is included for when the reader needs to sit further from the computer. The card slots can be slid flush with the reader's front when in use (as shown in the picture), then slid back inside the reader's shell for storage and travel.

lexar_udma_dualslot_thumb.jpg Lexar Professional UDMA Dual-Slot

This CompactFlash and SD/SDHC USB 2.0 reader features a pop-up design that, when popped down, keeps its twin card slots protected. It connects to the computer via a detachable cable.

sandisk_ext_usb_thumb.jpg SanDisk Extreme III USB (original version)

This CompactFlash and SD/SDHC USB 2.0 reader is one of the most dependable and goof-proof readers we've ever used. Though it's a couple of years old now and not the speediest, it remains a favourite here because it just works.

SD/SDHC read speeds with this reader are effectively the same as those from numerous other older USB 2.0 SD/SDHC readers on the market, since like this one, many other brands and models were (and still are) built using reader controllers from Genesys Logic. The SanDisk Extreme III USB (original version) connects to the computer via a detachable cable.

(In mid-2008 this model was replaced in SanDisk's lineup with a CompactFlash-only reader that has a similar name and appearance, but no SD/SDHC slot.)

sandisk_multicard_thumb.jpgSanDisk ImageMate Multi-Card USB 2.0

Slated to ship in November 2008, this SD/SDHC/SDXC USB 2.0 reader features a proprietary data timing mode designed expressly for faster throughput with SanDisk's Extreme III 30MB/s Edition cards. With all other brands and models of this card type, the ImageMate Multi-Card USB 2.0 operates as a standard reader.

The ImageMate Multi-Card USB 2.0 includes a removable, magnetically attached three-legged stand. It connects to the computer via a detachable cable. It's hard to tell from photos of the reader that it's exceptionally small, particularly when separated from its stand.

sandisk_allinone_thumb.jpgSanDisk ImageMate All-in-One USB 2.0

Ghis four-slot reader accepts CompactFlash (CF I only, which means thicker CF II cards such as the Hitachi Microdrive won't fit), SD/SDHC/SDXC and numerous other memory card formats.

Unlike the ImageMate Multi-Card reader, the ImageMate All-in-One doesn't include support for the proprietary data timing mode found in SanDisk's Extreme III 30MB/s Edition cards. This means it doesn't deliver an extra speed boost when paired with one of these specific cards.

The ImageMate All-in-One USB 2.0 includes a removable, magnetically attached three-legged stand. It connects to the computer via a detachable cable.

The Systems

The test systems are:

iMac_thumb.jpg iMac 27 inch (2010)

Quad-Core Intel Core i5 2.66GHz, 8GB RAM, 1TB hard drive, Mac OS X 10.6.x. This computer is used for FireWire 800 and USB 2.0 reader testing.


macbook_pro_thumb.jpg MacBook Pro 17 inch (2009)

Intel Core 2 Duo 3.06GHz, 8GB RAM, 640GB RAID 0 hard drive array, Mac OS X 10.6.x. This computer is used for ExpressCard 34 adapter testing.

thinkpad_t60_thumb.jpg Lenovo Thinkpad W700ds

Intel Core 2 Quad 2.53GHz, 4GB RAM, 256GB 7200 RPM hard drive, Windows 7 Home Premium 64-Bit. This computer is used for ExpressCard 34 testing.

vista_thumb.jpgAcer Aspire M5811

Intel Core i5 3.2GHz, 8GB RAM, 1TB 7200RPM hard drive, Windows 7 Home Premium 64-Bit. This computer is used for SATA/eSATA and USB 3.0 reader testing.

The Results

The SD/SDHC read speed results below were generated with QuickBench 4, a cross-platform benchmarking utility we like because it produces numbers (on the Mac in particular) that equate closely to real world performance when using the operating system to copy digital SLR JPEG and RAW files from a memory card to the computer. QuickBench was set to Large Test (2-10MB), Allow Cache Effects was turned off and 3 test cycles were run. All cards were secure erased and formatted in a Canon EOS-1D Mark IV before testing.

Use the NEXT FOUR READERS and PREVIOUS FOUR READERS links to navigate through all the reader data. The fields marked in blue represent the fastest read speed for that card. In the case of an incompatibility between card and reader, the field is marked --Error--.
