With the recent debate on various HD cameras going to flash media and hard drives, I thought it'd be appropriate to name a few drives that make on location backup and even editing easier.
With many newer laptops carry FW400, FW800 and even eSATA connections, it's now possible to get fast enough drive enclosures to make archiving in the field easier. With the use of eSATA connections allows fast speed access via the laptop. Note that presently eSATA express 34 cards in express 34 slots on laptops are limited to 134MB/s, probably due to the architecture of the slots. Comparatively a real Express 54 slot on a desktop, which can easily go much faster.
The first compact enclosure to hit 1TB is the La Cie Big Little Disk Quadra. This enclosure is made of aluminum and mates 2 2.5" 500GB SATA drives together. The interfaces include eSATA, FW800 (400 compatible) and USB 2.0. What is cool about this device is you can use it in RAID 0 or 1 and it can be FW bus powered. However the eSATA and USB interfaces rely on the supplied power supply, which limits it's portability. It's also pretty heavy but it does look very cool. I have the older version. The price: MSRP$699 Street approx $550.
A much more versatile device is the Sonnet Technologies Fusion F2 1 TB system. This design is a bigger unit than the La Cie but it does something that the La Cie can't. It can use the eSATA interface while using the FW bus power from your laptop, making it a truly portable drive solution. It also uses 2 2.5 SATA drives and can be set as RAID 0 or 1. It can even take Pro Res HD HQ from an AJA iOHD. MSRP$999 Street approx $800
Now if those alternatives are a little too much investment, there are cheaper, less versatile (but no less functional) storage options.
The Nextodi Extreme ND 2700 enclosure that have built-in 9 format card reader onto a 2.5" SATA drive which has eSATA and USB connections. It has its own power source (Li ION battery that is rechargeable) and automatically downloads the cards without the use of a laptop. The Video Storage ND2725 allows the backup of Sony's EX series and Panasonic HVX series cameras with direct USB connections to the cameras. Both enclosures can fit a 2.5" 500GB harddrive. Both have li ION batteries built in which can be recharged via the USB port. However, they are technically not buspowered as the battery will drain even when plugged in via USB.
With these new tools, field backup and even editing has taken new life and offers compact solutions for those shooting on locations or travelling.
