Dude, Here’s Your 100TB Flash Drive!

It’s been only a month since I wrote about Samsung’s 30TB solid state disk and already the bar has been set higher.  This week Nimbus Data announced a 100TB 3.5″ SSD (the DC100) that blows past the proof of concept 60TB drive demonstrated by Seagate only a few years ago.  How real is 100TB in… Read more »

Rent Out Your Spare Disk Space With Storj

As I think I’ve mentioned a few times on this and other blogs before, around the late 1990s I looked at the practicality of creating a distributed storage platform that would act as a backup for personal storage.  As the amount of data being personally stored was increasing (via photos, video and other content), being… Read more »

The Risk of Shared Service Level Agreements
