Anyone fancy testing the 'unlimited' drive writes claim on Nimbus Data's 100TB whopper SSD?
Found on The Register on Monday, 19 March 2018
The 100TB ExaDrive has a 3.5-inch enclosure, a SATA interface, and is built from MLC (2bits/cell) 3D NAND. It has, Nimbus claims, the lowest power/TB rating, down to 0.1W/TB, 85 per cent lower than Micron's 5100 drive.
Savings offered by the ExaDrive over these drives are physical space and power. A theoretical 100PB constructed from 3,264 Samsung PM1643 SSDs would need 6 x 45U racks, according to Nimbus, and around 50kW of power.
The same ExaDrive-sourced capacity would need one rack, 990 drives and draw about 16kW.
At 500MB/s write speed, that 100TB drive could be loaded with roughly 41TB per day. Other manufacturers give a warranty for up to 10 complete drive writes per day. So basically Nimbus just makes drives slower so that they last longer; no magic.
