CF/SD Performance Database Archive - Continued

July 29, 2004: The D2H section of the database is no longer being updated, as we no longer have access to this camera.

Any digital SLR can benefit from a fast CompactFlash card. Like the D1H before it, however, Nikon engineers have done a superb job of minimizing the need for maximum card speed with the D2H. Its generous memory buffer in all file formats, ultra-quick write interface and a playback mode that allows for photos to be reviewed and zoomed immediately after they're shot (even while the camera is still writing to the card) means a speedy CompactFlash card is not a necessity with this camera. All digital SLRs should be designed like this.

CompactFlash Write Speed - Nikon D2H (Firmware Version A: 2.00 B: 2.00)

The data in the table below was derived by timing how long it took the Nikon D2H to write out 20 JPEG Fine and 20 uncompressed RAW .NEF photos to the card. Timing commenced when the camera's card status light illuminated, and stopped when the light went out. Each test cycle was performed 3 times (if the card's capacity allowed for that) to ensure accurate results.

Card-to-card speed variation within the same brand and model, photographing scenes of varying detail and at different ISO settings - these and other factors may slightly alter write speed performance. As a result, write speed differences of 5% or less from card to card in the table below should be considered insignificant. If one card's write speed is within 5% of another's, the two cards are likely to offer effectively the same performance in the real world. Similarly, it's unlikely that most photographers would notice a difference between the fastest card and one that was up to 10% slower.

The results are arranged in the table from fastest to slowest (based on JPEG write speed). The top 10% (based on JPEG write speed) are marked in blue.

(1) To help determine whether the card you purchase is substantially similar to the one tested, the card's description includes an identifier - series number, internal name or other unique value - where possible and applicable.
(2) Many companies sell CompactFlash media; relatively few actually design and manufacture the key internal components, including the controller and flash memory. This column lists the manufacturer of the controller.
(3) Type I CompactFlash cards are 3.3mm in thickness; Type II, 5.0mm.
(4) K/sec = Kilobytes per second (1 kilobyte = 1024 bytes); MB/sec = Megabytes per second (1 megabyte = 1024 kilobytes).
(5) Companies that source CompactFlash cards from Toshiba may opt for either the faster single level cell (SLC) or slower (but less expensive to manufacture) multi level cell (MLC) architecture. The Kingston cards tested were MLC; the company does, however, offer SLC-based CompactFlash cards on special order. Kingston's SLC-based cards have "-S" appended to the end of their part number, ie CF/512-S. Not all of Kingston's distributors will have the SLC cards listed among the products they can ship to dealers. For more information, contact Kingston.
(6) Delkin has not revealed the design and manufacturing partner for their Pro line of CompactFlash cards.
(7) These cards contain controllers from an unknown manufacturer, likely of Taiwanese origin.
(8) This camera's built-in formatter will format cards over 2GB as FAT32 with a 32K cluster size. This cluster size ensures more efficient camera-to-computer transfers than the more-typical default FAT32 cluster size of 4K.
(9) This card, which began to ship in mid-March 2004, contains faster memory than the original 40X card. Lexar has revamped their entire 40X Pro Series lineup, from 256MB to 4GB, with the faster memory, though we've only tested the 1GB model. The packaging for the revamped 40X doesn't indicate that the card inside is different from an original 40X, though the card itself does: if the series number stamped on the card's edge ends in C977, it's a revamped 40X.
(10) Lexar began shipping their 80X line of cards in late June 2004. The card marked *first edition* in the table is a production model representative of the 80X lineup that began shipping in late June 2004. For now, it's safe to assume that any 80X card available at dealers until at least the middle of October 2004 (and perhaps beyond) will be a first edition model. Lexar promises that second edition models will be readily identifiable as such when they hit store shelves, with details on how to distinguish them from first edition cards forthcoming at the time of their release. Note that the first edition/second edition designation is our own, and is not how Lexar plans to distinguish the original and revamped 80X line.
