A flash drive has increased endurance and longevity by reducing writes to flash. An Endurance Translation Layer (ETL) is created in a DRAM buffer and provides temporary storage to reduce flash wear. A Smart Storage Switch (SSS) controller assigns data-type bits when categorizing host accesses as paging files used by memory management, temporary files, File Allocation Table (FAT) and File Descriptor Block (FDB) entries, and user data files, using address ranges and file extensions read from FAT. Paging files and temporary files are never written to flash. Partial-page data is packed and sector mapped by sub-sector mapping tables that are pointed to by a unified mapping table that stores the data-type bits and pointers to data or tables in DRAM. Partial sectors are packed together to reduce DRAM usage and flash wear. A spare/swap area in DRAM reduces flash wear. Reference voltages are adjusted when error correction fails.

A Virtual-Memory Device (VMD) driver and application execute on a host to increase endurance of flash memory attached to a Super Enhanced Endurance Device (SEED) or Solid-State Drive (SSD). Host accesses to flash are intercepted by the VMD driver using upper and lower-level filter drivers and categorized as data types of paging files, temporary files, meta-data, and user data files, using address ranges and file extensions read from meta-data tables. Paging files and temporary files are optionally written to flash. Full-page and partial-page data are grouped into multi-page meta-pages by data type before storage by the SSD. ramdisks and caches for storing each data type in the host DRAM are managed and flushed to the SSD by the VMD driver. Write dates are stored for pages or blocks for management functions. A spare/swap area in DRAM reduces flash wear. Reference voltages are adjusted when error correction fails.

A controller for a Super Enhanced Endurance Device (SEED) or Solid-State Drive (SSD) increases flash endurance using a DRAM buffer. Host accesses to flash are intercepted by the controller and categorized as data types of paging files, temporary files, meta-data, and user data files, using address ranges and file extensions read from meta-data tables. Paging files and temporary files are optionally written to flash. Full-page and partial-page data are grouped into multi-page meta-pages by data type in the DRAM before storage by lower-level flash devices such as eMMC, UFS, or iSSD. Caches in the DRAM buffer for storing each data type are managed and flushed to the flash devices by the controller. Write dates are stored for pages or blocks for management functions. A spare/swap area in DRAM reduces flash wear. Reference voltages are adjusted when error correction fails.

The invention provides a VMD (Virtual-Memory Device) executed on a host and application thereof for enhancing flash memory endurance of an SEED (Super Enhanced Endurance Device) or an SSD (Solid-State Drive). The VMD driver utilizes a high-level or a low-level filtering driver to intercept and capture access to flash memory of the host and to sort access to the flash memory of the host into paging file data type, temporary files, meta data and user data files by using address range and file extensions read by the meta data. Optionally, the paging files and the temporary files are written in the flash memory. Full pages and local pages are grouped into multi-page metapage according to data type before SSD storage data passes. A virtual RAM disk and cache storing the data type in the host DRAM are managed and refreshed to SSD through the VMD driver. Write data is stored for blocks or pages managing functions. Flash memory abrasion is reduced in a backup/exchange area in the DRAM. The reference voltage is adjusted when error correction fails.

An automated system for software installation in a build-to-order information handling system. In one embodiment of the invention, a plurality of software applications are received and are disassembled to separate the individual constituent program files. These program files are decompressed and are stored in temporary file directories. Program files that are common to each of the software applications are identified and indexed.

A method and apparatus for minimizing the size of the cache that is required to store software packages for installation on an information handling system. An analysis is conducted on the individual program files contained in a software application file. In the analysis, the software application file is disassembled into the individual program files and each of the program files is decompressed and stored in temporary file directories. Files that are common to each of the software packages are identified. After the file comparison, the method and apparatus of the present invention is used to re-group the files to generate a composite program file library that contains all of the program files needed to regenerate the software application files. This composite program file library is then stored on a cache in a factory server used to manufacture information handling systems in a build to order process.

A system and method for automatically executing a participating application upon insertion of a removable media into a computing device. When the computing device detects that the removable media containing has been inserted, a task disk control file is read from the removable media. The task disk control file contains all of the configuration information necessary to run the participating application from the removable media The participating application is then launched for use by a user. After the user is finished using the participating application, the removable disk is automatically ejected. In addition to monitoring for insertion of the removable media, events such as a completion of the self-contained application and a request to eject the media are monitored. When a completion event is encountered, all data files are saved, temporary files deleted and configuration information removed prior to the removable disk ejection. When an ejection event is encountered, the computing device is instructed to wait until the completion events are executed prior to actual ejection of the removable media.

The invention discloses a method for encrypting files by adopting an encryption sandbox, which borrows ideas from the sandbox principle. When opened, a filed is copied and reoriented to a virtual disk, and all editing operations are performed in the virtual disk; when closed (or every once in a while), the file is encrypted and copied and covers the original file to achieve the effect of encryption. All files stored in the virtual disk are temporary files which can be deleted, but the deletion can not influence a system, which is just like a sandbox. With the method, the stability of encryption and decryption can be improved and the policy setting can be simplified.
