040904 - performance on SDS. ref SDS 1 9J3L

040917 - ..
040918 - 1. A solid-state drive (SSD), sometimes called a solid-state disk
040919 - or electronic disk, is a data storage device that uses
040920 - solid-state memory to store persistent data with the intention
040921 - of providing access in the same manner of a traditional block
040922 - I/O hard disk drive. SSDs are distinguished from traditional
040923 - magnetic disks such as hard disk drives (HDDs) or floppy disk,
040924 - which are electromechanical devices containing spinning disks
040925 - and movable read/write heads. In contrast, SSDs use microchips
040926 - that retain data in non-volatile memory chips and contain no
040927 - moving parts.[1] Compared to electromechanical HDDs, SSDs are
040928 - typically less susceptible to physical shock, are silent, have
040929 - lower access time and latency, but are more expensive per
040930 - gigabyte (GB). SSDs use the same interface as hard disk
040931 - drives, thus easily replacing them in most applications.[2]
040933 - ..
040934 - 2. As of 2010, most SSDs use NAND-based flash memory, which
040935 - retains memory even without power. SSDs using volatile
040936 - random-access memory (RAM) also exist for situations that
040937 - require even faster access, but do not necessarily need data
040938 - persistence after power loss, or use external power or
040939 - batteries to maintain the data after power is removed.[2
040941 - ..
040942 - 3. A hybrid drive combines the features of an HDD and an SSD into
040943 - one unit, containing a large HDD and a smaller SSD cache to
040944 - improve performance of frequently accessed files. These can
040945 - offer near-SSD performance in most applications (such as
040946 - system startup and loading applications) at a lower price than
040947 - an SSD. These are not suitable for data-intensive work, nor do
040948 - they offer the other advantages of SSDs.
040950 - ..
040951 - 4. Windows 7
040952 -
040953 - Windows 7 is optimized for SSDs[92][93] as well as for
040954 - traditional magnetic hard disks. The OS looks for the presence
040955 - of an SSD and operates differently with that drive. If an SSD
040956 - is present, Windows 7 will disable disk defragmentation,
040957 - Superfetch, ReadyBoost, and other boot-time and application
040958 - prefetching operations. It also includes support for the TRIM
040959 - command to reduce garbage collection of data which the OS has
040960 - already determined is no longer valid. Without support for
040961 - TRIM, the SSD would be unaware of this data being invalid and
040962 - would unnecessarily continue to rewrite this data during
040963 - garbage collection causing further wear on the SSD.[

041080 - By........... S HOgan in The Blog
041082 - ..
041083 - The next big improvement for your computer is here. The always
041084 - spinning, ever failing hard drive is becoming an artsy door
041085 - stop, replaced by Solid State Drives (SSD). They have a lot
041086 - going for them but there are also some misconceptions about
041087 - what they provide.
041089 - ..
041090 - Untill now, cooling fans, optical drives, power supplies and
041091 - hard drives, all had moving parts. Moving parts and wear go
041092 - hand in hand, so it?s no surprise that hard drives are at the
041093 - top of everyones failure list. Now, thanks to SSD technology,
041094 - it?s possible to put together a consumer computing system with
041095 - no spinning hard drive or optical drive. You could conceivably
041096 - get by without even a cooling fan but why try. Using one low
041097 - rpm fan would provide fresh cool air with little to virtually
041098 - no noise.
041100 - ..
041101 - Lets take a real look at what SSD drives are, and what they
041102 - can offer us in real life improvements.
041104 - ..
041105 - PHYSICAL CONSTRUCTION
041107 - ..
041108 - Size. Their small 2.5 in. x 4 in. size makes them perfect for
041109 - use in desktops, laptops, and notebooks. In fact they use the
041110 - same form factor as your current SATA laptop drive. They are
041111 - available in a 1.8 in. size in addition to the 2.5 in. size
041112 - popular now. The technology on the 1.8 sized drive is actually
041113 - faster, but the 2.5 size is getting all the action due to
041114 - manufacturing costs.
041116 - ..
041117 - Data And Power Interface. SSD drives use the exact same
041118 - connections as existing SATA and SATA II drives. Some of the
041119 - lower priced SSD drives even come with an IDE connection.
041121 - ..
041122 - If your laptop uses a standard SATA interface you can just
041123 - unplug that drive and replace it with the new SSD. The drive
041124 - holder/heat sink and securing mechanism are interchangeable.
041126 - ..
041127 - Maintenance is much changed when using SSDs.
041129 - ..
041130 - DO NOT DEFRAG.
041132 - ..
041133 - Defragging degrades drive performance. This caution should be
041134 - placed in clear view, on the drive itself. New owners should
041135 - be made aware before physically installing this hardware.
041136 - Drive defragmentation has become such a standard procedure that
041137 - itâ??s likely many will defrag before knowing the consequences.
041139 - ..
041140 - This supplements notice in article reviewed above that Windows 7
041141 - disables defragmentation feature, relies on "trim" technology to
041142 - optimize performance of SSD storage devices. ref SDS 0 084G
041143 -
041144 - [On 120525 1033 research from Mydefrag company that sells
041145 - "mydefrag.exe" indicates using this software program has
041146 - benefits. ref SDS 6 MR6K
041148 - ..
041149 - Article "To SSD or Not to SSD" concludes...
041150 -
041151 - Drive Life of SSD drives is much extended over standard
041152 - drives. Because of the extended time without failures and the
041153 - rugged build of the drive having no moving parts, the military
041154 - was one of the first to adopt this technology. Drive life is
041155 - expressed as MTBF or Mean Time Between Failures. For SSD
041156 - drives this can be as long as 2,000,000 hours and is years
041157 - beyond what would be needed.
