SanDisk 1GB SD WORM (Write Once, Read Many)

How does it work?

Write Once, Read-Many (WORM) technology from SanDisk is the best solution that ensures the evidence you collect cannot be deleted, over-written, or tampered with. It's tamper-proof evidence collection. SanDisk SD™WORM technology offers two key features for law-enforcement applications, and we have the evidence to prove these features. First and foremost, it truly is a write-once technology. When data is recorded, it's instantly write protected. You can physically destroy the data outright, but you can never alter it.

Extensive life-testing under accelerated-stress conditions has shown that SD™WORM has a guaranteed life expectancy in excess of one hundred years. Furthermore, it does not require expensive climate-controlled archival storage - you can store it under normal conditions as with other evidence.

From the outside, SD™WORM works like conventional SD Cards, with a few key differences. First, only compatible devices can write to it. And inside, SD™WORM uses SanDisk-proprietary technology to offer the convenience of flash memory combined with tamper-proof, hundred-year data storage*.

How do I use it?

You don't need any special training to use SD™WORM. Just insert one in any SD™WORM compatible camera or audio recorder, and record your evidence. When you're done, insert the card into your laptop or PC, and use your evidence. Don't worry about erasing it - it can't happen.

You can read the contents of a SanDisk SD™WORM card in any SD compatible device. Any. This includes virtually all PCs, laptops, PDAs, and many other devices. They fit the same devices as any SD card, but the cards can only be written by cameras, audio recorders, and other devices designed for the purpose. Devices you control, so you know what was recorded, by whom, and when. Several major digital camera vendors offer compatible devices. Click for more information.

Each SD™WORM card has a unique serial number. When issued for a case, the evidence collected for that case is preserved, with a clear and unimpeachable chain-of-custody. You do less paperwork, fewer files transfers, and fewer backups. And you get more and better work done.

What do I need?

SanDisk's memory cards let you collect and record digital evidence just as you do today. Our Write-Once, Read-Many (WORM) technology combines the convenience of SD memory cards with the integrity of analog media, all with the longevity to last for one hundred years*.

SD™WORM cards plug into a SD WORM enabled evidence camera like a conventional SD Card, and plug into your PC or other equipment in the same way. Use them like any SD Card, with the secure knowledge that the evidence you collect is there, for life.

Acceptance By Police

In Japan, the agencies related to the National Police have conducted an extensive trial of both the SD WORM memory card's technology and its practical applications. As a result, they have adopted the solution and are deploying it across the force, to police officers, investigators, and other law enforcement personnel.

Expected Life

SD WORM cards last for one hundred years*. SanDisk has over twenty years of experience in data storage. We've been a leader in the industry in all types of flash and non-volatile storage. We've developed and studied this technology over many years.

We would not put our name on it if we weren't willing to back it with our reputation.

Why SD WORM Is Better

SD™WORM cards are a superior solution for many reasons. First, they are tamper-proof. No other general-purpose media is. Sure, you can use conventional flash cards, then transfer the data to recordable CDs or DVDs, but this adds extra steps and complicates the chain-of-custody.

Second, SD™WORM cards are easier to use. They plug into your evidence camera like a conventional SD Card, and plug into your PC or other equipment in the same way. Use them like any SD Card, with the secure knowledge that the evidence you collect is there, for a hundred years*.

Chain-of-Custody

Tamper-proof evidence collection simplifies chain-of-custody.
How does this help you? First, it saves you time and effort. It's fully read-compatible with most existing storage and processing systems. So the media your officers use is the media you process is the media you archive.

Each SD™WORM card has a unique serial number. When issued for a case, the evidence collected for that case is preserved, with a clear and unimpeachable chain-of-custody. You do less paperwork, fewer file transfers, and fewer backups. And you get more and better work done. It virtually eliminates processing mistakes or overwritten files. The unique serial number simplifies the chain-of-custody documentation, and provides positive identification for all your case data.

Finally, it has already received evidentiary acceptance in a major court system. Because the SD™WORM card can be read in any PC, you have the ability to DIRECTLY display the evidence, and the chain-of-control, in the courtroom.

Compatibility

SD™ WORM memory cards work almost exactly like the SD cards you're accustomed to. The card is designed such that it can be written to, like a conventional flash memory card, but only once.

The circuit requires no power to maintain data, and uses semiconductor technology, which remains stable up to one hundred years*.

From the outside, SD™WORM works like conventional SD Cards, with a few key differences. First, only compatible devices can write to it. And inside, SD™WORM uses SanDisk-proprietary technology to offer the convenience of flash memory combined with tamper-proof, hundred-year data storage*.

SD™ WORM Memory Cards In The Japanese Police Force

In Japan, the agencies related to the National Police have conducted an extensive trial of both the SD WORM memory card's technology and its practical applications. As a result, they have adopted the solution and are deploying it across the force, to police officers, investigators, and other law enforcement personnel.

Reliable Record-Keeping

In commercial markets, electronic cash registers (ECR) and point of sales machines (POS) can leverage the unique SD WORM card features to preserve the integrity of receipts for accounting and tax purposes. And in the medical field, SD WORM cards can provide long-term storage of medical records and diagnostic imagery.

SD™ WORM technology from SanDisk combines the 21st-century convenience of flash memory technology with the permanence of an old-fashioned photograph. It's film for digital devices. SanDisk has developed a proprietary memory technology that records data once and forever*.
