About This Product  The ThinkSystem 5400 PRO Read Intensive SATA 6Gb SSDs are general-purpose self-encrypting SSDs (SEDs) based on the Micron 5400 PRO platform and are available in capacities ranging from 240GB to 7.86TB. They are engineered for greater performance and endurance in a cost-effective design and to support a broader set of workloads.This product guide provides essential presales information to understand the 5400 PRO SSDs their key features and specifications components and options and configuration guidelines. This guide is intended for technical specialists sales specialists sales engineers IT architects and other IT professionals who want to learn more about the 5400 PRO SSDs and consider their use in IT solutionsAutomatic encryption It is vital that a company keep its data secure. With the threat of data loss due to physical theft or improper inventory practices it is important that the data be encrypted. However challenges with performance scalability and complexity have led IT departments to push back against security policies that require the use of encryption. In addition encryption has been viewed as risky by those unfamiliar with key management a process for ensuring a company can always decrypt its own data. Self-encrypting drives comprehensively resolve these issues making encryption both easy and affordable. When the self-encrypting drive is in normal use its owner need not maintain authentication keys (otherwise known as credentials or passwords) in order to access the data on the drive. The self-encrypting drive will encrypt data being written to the drive and decrypt data being read from it all without requiring an authentication key from the ownerInstant secure erase The self-encrypting drive provides instant data encryption key destruction via cryptographic erasure. When it is time to retire or repurpose the drive the owner sends a command to the drive to perform a cryptographic erasure. Cryptographic erasure simply replaces the encryption key inside the encrypted drive making it impossible to ever decrypt the data encrypted with the deleted key. Self-encrypting drives reduce IT operating expenses by reducing asset control challenges and disposal costs. Data security with self-encrypting drives helps ensure compliance with privacy regulations without hindering IT efficiency. So called Safe Harbor clauses in government regulations allow companies to not have to notify customers of occurrences of data theft if that data was encrypted and therefore unreadableAuto-locking Insider theft or misplacement is a growing concern for businesses of all sizes; in addition managers of branch offices and small businesses without strong physical security face greater vulnerability to external theft. Self-encrypting drives include a feature called auto-lock mode to help secure active data against theft. Using a self-encrypting drive when auto-lock mode is enabled simply requires securing the drive with an authentication key. When secured in this manner the drive’s data encryption key is locked whenever the drive is powered down. In other words the moment the self-encrypting drive is switched off or unplugged it automatically locks down the drive’s data.When the self-encrypting drive is then powered back on it requires authentication before being able to unlock its encryption key and read any data on the drive thus protecting against misplacement and theft.While using self-encrypting drives just for the instant secure erase is an extremely efficient and effective means to help securely retire a drive using self-encrypting drives in auto-lock mode provides even more advantages. From the moment the drive or system is removed from the data center (with or without authorization) the drive is locked. No advance thought or action is required from the data
