Viking’s solid state drives are available in Enterprise and Client versions:
Enterprise SSD – An Enterprise SSD contains hardware and firmware that
detect and manage power failures. This allows the drive to flush the controller
cache and harden data to NAND flash. No data is lost or corrupted.
Client SSD – A Client SSD does not include power failure detection or
management features. MLC NAND, as opposed to SLC NAND, can become
corrupted if power is removed during a write, also known as lower page
corruption. Therefore, a Client SSD using MLC NAND is well-suited in a system
that already manages power fail events, allowing for graceful SSD shutdown.
Accordingly, system support should include issuing a Standby Immediate
command to the SSD while maintaining power for at least 50ms.
If a Client drive with MLC NAND is used in a system that does not manage power
failures and shutdowns, there is a small chance of data corruption. Viking Client
SSD’s take sophisticated hardware and firmware measures to prevent or mitigate
such issues making the chance of corruption very small.
If the SSD controller detects data corruption, the drive will be locked. The only
way to recover the drive is to return it to the factory for reprogramming; all data
will be lost.
