Help Me Choose: Primary Storage
Primary storage is where the operating system, software applications, files and data are stored on a PC. The following factors should be taken into account when deciding what type of storage option will best meet your needs.
Primary Storage Decision Factors
- Capacity requirements. More gigabytes (GB) mean more capacity. Presentations, videos, spreadsheets and photos take up much more space than word processing documents and emails, and will require a hard drive with more storage capacity. High-capacity hard drives help to provide your enterprise with a scalable technological foundation that can meet its changing needs — both today and in the future.
- The importance of the data. Data loss is always a concern. Data redundancy on multiple drives (RAID 1) and backing up your system to external storage are the best way to prevent data loss in the case of drive failure.
- Performance. System performance and boot time are influenced by the type of storage you select. For hard drives, the speed of the drive, measured in revolutions per minute (rpm), indicates the performance of the drive. A 7200 rpm HDD is standard performance for desktop applications.
SATA, or serial advanced technology attachment, is a serial link — a single cable that creates a point-to-point connection between two devices.
All Vostro™ systems use SATA 3.0Gb/s (formerly SATA II), a serial revision of the popular legacy ATA bus, featuring a raw data transfer rate of up to 3.0 Gbps, small connectors and cables, and a dedicated bandwidth and cable for each device. SATA 3.0 Gbps delivers an excellent blend of high performance and configuration convenience.
All Vostro™ systems use native command queuing (NCQ), a technology that increases drive performance by internally optimizing the order in which read and write commands are executed to minimize head movement within the drive.
