 SINGLE LARGE EXPENSIVE DRIVE Definition
We define SINGLE LARGE EXPENSIVE DRIVE |
SINGLE LARGE EXPENSIVE DRIVE - Back in the early days of hard disks you had two choices: SLED or RAID. SLED systems used a single high capacity hard drive to store lots of data. The drive may have contained a platter that was three feet (one meter) across, and it was very expensive. RAID allowed users to link a bunch of smaller, cheaper hard drives together for redundancy and to save the cost of a SLED. As costs and physical sizes of high capacity hard drives decreased and physical drive sizes were standardized, the term SLED has lost its meaning. |
