Toshiba Tecra R850-1CD HDD Solid State Disk (SSD) 500GB Samsung 840
Samsung 840-series 500GBThis Samsung 840 500GB Solid State drive (SDD) is equipped with
the current Serial ATA revision 3.0 technology and permitted so a
transfer speed of up to 6 Gbit/s.The new
SATA III standard is downward compatible. Therefore the SSD hard disk is also ready for operation with a conventional Serial ATA-300 and/or SATA-II.
SSD (Solid State Drive) is a technology based on NAND-Flash-memory. The information is stored in form of electrical states of charge. The states of charge remain if the power supply is missing. Therefore the SSD is seen as a equivalent replacement of the Hard Disk Drive (HDD).
The box contains:
- 6.4 cm (2.5 inch) SSD 840 Series
- Samsung software & manual CD
- Quick user manual
Pros of the SSD:
- working noiseless
- low power-consumption
- longer period of operation in battery-mode
- extremely fast access times
- no mechanical abrasion
- extremely tough against agitation and vibration
- SSD's tolerate temperatures between 0 and 60 degree of Celsius
Specifications:
capacity: 500 GB
size: 2.5 "
interface: Serial ATA Revision 3.0 - 6.0 Gbit/s
height: 7mm
Serial ATA (SATA or Serial Advanced Technology Attachment) is a computer bus interface for connecting host bus adapters to mass storage devices such as hard disk drives and optical drives.
Serial ATA was designed to replace the older ATA (AT Attachment) standard (also known as EIDE), offering several advantages over the older parallel ATA (PATA) interface: reduced cable-bulk and cost (7 conductors versus 40), native hot swapping, faster data transfer through higher signalling rates, and more efficient transfer through an (optional) I/O queuing protocol.
SATA host-adapters and devices communicate via a high-speed serial cable over two pairs of conductors. In contrast, parallel ATA (the redesignation for the legacy ATA specifications) used a 16-bit wide data bus with many additional support and control signals, all operating at much lower frequency. To ensure backward compatibility with legacy ATA software and applications, SATA uses the same basic ATA and ATAPI command-set as legacy ATA devices.
As of 2009[update], SATA has replaced parallel ATA in most shipping consumer desktop and laptop computers, and is expected to eventually replace PATA in embedded applications where space and cost are important factors. SATAs market share in the desktop PC market was 99% in 2008.[2] PATA remains widely used in industrial and embedded applications that use CompactFlash storage, though even here, the next CFast storage standard will be based on SATA.
