Sandisk feels generous, open sources key tech that will supercharge any SSD — great news for AI, but not for your…
- Sandisk reduced SSD pre-conditioning times from days to only several hours
- SPRandom achieves steady state performance using only one complete drive write
- Open sourcing SPRandom gives hyperscalers faster deployment options
Sandisk has open sourced a key algorithm which can dramatically speed up the pre-conditioning process for solid-state drives (SSDs).
SanDisk Pseudo Random (or SPRandom) reduces the time required to prepare a drive for steady-state operation from over 160 hours to roughly 6.5 hours.
Traditional pre-conditioning methods require writing data two or more times the drive's total capacity using sequential and random operations. But the new algorithm writes to every logical address just once, completing the entire process in less than five percent of the original time.
SSD pre-conditioning matters for data centers and AI workloads
Fresh out of the box SSDs show variable performance, until they go through a process called pre-conditioning that stabilizes their behaviour.
During this...
