[Pages:34]Your Laptop's Midlife Crisis How to Help It Cope
Part 2 ? Upgrading Your Laptop's Hard Drive
Presentation to APCUG VTC - 5/07/16 G. Skalka
What is the Lifespan of a Laptop?
? Hardware is "current" for about 2 years ? Expect to avoid repair problems for about 4 years ? Could likely run for 10 years without problems if cared for ? "Useful" life is typically 5 years ? Varies with initial cost and capabilities ? Probably good for the useful life of the installed operating
system
Example: My two Fujitsu Laptops
? Lifebook AH531 - $380 new in Sept. 2011
? 15.6" display, Intel i3 processor
? Lifebook LH531 - $400 new in June 2012
? 14" display, Intel i5 processor
? Both have:
? 500 GB hard drive, 2 GB RAM ? USB 2.0, HDMI, 10/100/1000 LAN, 802.11N ? Dual-layer DVD-RW, 1.3 Mpixel camera ? Windows 7
Useful Life Trade-offs
? What they have going for them
? Still fairly fast ? Have most current interfaces ? Good operating system ? Appear to be reliable
? What they lack
? More RAM ? Larger hard drive and/or solid state drive ? USB3 ? Blu-ray drive
Most Popular Laptop Upgrades
? More memory ? Larger hard drive ? Solid-state drive ? Faster interfaces (USB3, Gigabit Ethernet, 802.11N
wireless) ? HDMI output ? Blu-ray drive ? New battery*
Why Upgrade Your Hard Drive?
? Increase storage space
? More room for data and applications
? Speed up laptop
? Magnetic drive (HDD)
? Higher rotational speed (5400 or 7200 RPM) ? Faster electrical interface (3 or 6 Gbits/s)
? Solid State Drive (SSD)
? Faster access time ? Faster electrical interface
Hard Drive Interfaces
? PATA - Parallel ATA (AT attachment)
? Old technology - uses pins on drive
? SATA - Serial ATA
? Standardized serial high-speed interface
? Same for 2.5" and 3.5" hard drives ? Uses fingers on connector
SATA Interface Speeds
? SATA Revision 2
? 3 Gbit/s, 300 MB/s ? SATA/300
? SATA Revision 3
? 6 Gbit/s, 600 MB/s ? SATA/600
? SATA Revision 3.2
? 16 Gbit/s, 1969 MB/s
? Rev. 3 is backwards compatible with Rev. 2
