| - | * Volume - The recorded images are large: think 100k x 50k pixels. Sometimes in 16-bit RGB color resolution. An individual slide can be anywhere between a 100 MB in size (a needle biopsy e.g.), or several GB in size (a solid tumor section samples scanned at 40X magnification) | + | * Volume - The recorded images are large: think 100k x 50k pixels in 16-bit RGB color resolution.

This poses challenges in terms of how much pre-treatment and time you can spent on any individual slides. | + | * Velocity - Data comes in rapidly, with 100s of slides being scanned on a daily basis.

| - | This hybrid configuration model also means you can scale easily over time: you can start with a setup whereby your slides are mostly placed on a (big) local hard disk. After a while, you switch over to your organization's network storage. Even at a later stage, you can transparently migrate to S3-compliant cloud storage. When you have an external collaborator that temporarily wants to share their slide collection with you, you can ask them to setup an FTP server and patch a root-directory through to that one. | + | This hybrid configuration model also means you can scale easily over time: you can start with a setup whereby your slides are mostly placed on a (big) local hard disk.
