The SSD and the HDD then co-exist to drive optimal performance in the upgraded desktop For notebooks, SSDNow drives are a perfect replacement for hard drives resulting in faster, more reliable performance. Making this change will improve a notebook's efficiency in a wide range of tasks, from booting up to running the most robust operating system and demanding applications. SSDNow uses a standard SATA interface but, unlike a regular HDD, SSD is very rugged and built with no moving parts, making it ideal for power users and road warriors who push the limits of their notebooks. Other benefits include reduced power usage, less noise and less heat generation. Product Features Performance – enhances productivity; makes users more efficient Innovative – 2.5 inch form factor; uses NAND flash memory components Silent – Runs silent and cool with no moving mechanical parts Reliable – less likely to fail than a standard hard drive Shock Resistant – No moving mechanical parts so the SSD handles rougher conditions Supports S.M.A.R.T. – Self-Monitoring, Analysis and Reporting Technology tells the user when a drive is about to fail Storage Drive Size 2.5 Inches Memory Type NAND Flash Memory Size 64 GB Memory Package Solid State Drive RAID Support , Performance Data Transfer Rates Data Transfer Rates: Read Speed 200 MB/s Write Speed 110 MB/s Mean Time Between Failure (MTBF) 1.0 Million Hours Latency Latency (Reads) , Latency (Writes) Interfaces/Ports Interface(s) SATA ( ) Environmental Operating Temperature Operating Temperature 0 to 70 °C Storage Temperature Storage Temperature -40 to 85 °C Operating Humidity - Humidity Vibration (Operating) 2.17 G (7-800 Hz) Vibration (Non-Operating) 20G (20-2000 Hz)
