Solis-state drive

0 comments
Is it time to say good bye your hard disk!?

Unbelievable isn’t it. However it’s true.

Let’s see what coming for us.

Solid-State Drive [ S.S.D ]

This is the new technology which already uses Apple Company in their laptop. It save our time, about 50 time faster than our hard disk. This S.S.D didn’t produce heat, so suitable for using inside laptop. Small size, so easy to move. Within few days this S.S.D will be popular both desktop & laptop computer.

Comparison HDD with S.S.D


Attribute or characteristic

Solid-state drive

Hard disk drive


Spin-up time

Almost Instantaneous; nothing mechanical to "spin up". May need a few milliseconds to come out of an automatic power-saving mode.

May take several seconds. With a large number of drives, spin-up may need to be staggered to limit total power drawn.


Random access time

About 0.1 ms - many times faster than HDDs because data is accessed directly from the flash memory.

Ranges from 5–10 ms due to the need to move the heads and wait for the data to rotate under the read/write head.


Read latency time

Generally low because the data can be read directly from any location; In applications where hard disk seeks are the limiting factor, these results in faster boot and application launch times.

Generally high since the mechanical components require additional time to get aligned.


Consistent read performance

Read performance does not change based on where data is stored on an SSD.

If data is written in a fragmented way, reading back the data will have varying response times.


Defragmentation

SSDs do not benefit from defragmentation because there is little benefit to reading data sequentially (beyond typical FS block sizes) and any defragmentation process adds additional writes on the NAND flash that already have a limited cycle life.

HDDs may require defragmentation after continued operations or erasing and writing data, especially involving large files.


Acoustic levels

SSDs have no moving parts and make no sound.

HDDs have moving parts (heads, spindle motor) and have varying levels of sound depending upon model.


Mechanical reliability

A lack of moving parts virtually eliminates mechanical breakdowns.

HDDs have many moving parts that are all subject to failure over time.


Susceptibility to environmental factors

No flying heads or rotating platters to fail as a result of shock, altitude, or vibration.

The flying heads and rotating platters are generally susceptible to shock, altitude, and vibration.

Magnetic susceptibility

No impact on flash memory.

No impact on flash memory.


Weight and size

The weight of flash memory and the circuit board material are very light compared to HDDs.

Higher performing HDDs require heavier components than laptop HDDs (which are light, but not as light as SSDs).


Parallel operation

Some flash controllers can have multiple flash chips reading and writing different data simultaneously.

HDDs have multiple heads (one per platter) but they are connected, and share one positioning motor.



Write longevity

Flash-based SSDs have a limited number of writes (1-5 million or more) over the life of the drive. Software controllers manage this limitation in such a way that drives can last for many decades before failure. SSDs based on DRAM do not have a limited number of writes.

Magnetic media do not have a similar limited number of writes but are susceptible to eventual mechanical failure.



Software encryption limitations

NAND flash memory cannot be overwritten, but has to be rewritten to previously erased blocks. If a software encryption program encrypts data already on the SSD, the overwritten data is still unsecured, unencrypted, and accessible (drive-based hardware encryption does not have this problem). Also data cannot be securely erased by overwriting the original file without special "Secure Erase" procedures built into the drive.

HDDs can overwrite data directly on the drive in any particular sector.


Cost per capacity

As of February 2011, NAND flash SSDs cost about (US)$.90–2.00 per GB.

As of February 2011, HDDs cost about (US)$0.05/GB for 3.5 in and $0.10/GB for 2.5 in drives.


Storage capacity

As of April 2011, SSDs come in different sizes up to 2TB but are typically not larger than 64-256GB, due to their high cost per GB.

As of April 2011, HDDs are typically 500GB-1TB but drives as large as 2 or 3 TB are also available.


Read/write performance symmetry

Less expensive SSDs typically have write speeds significantly lower than their read speeds. Higher performing SSDs have a balanced read and write speed.

HDDs generally have slightly lower write speeds than their read speeds.



Free block availability and TRIM

SSD write performance is significantly impacted by the availability of free, programmable blocks. Previously written data blocks that are no longer in use can be reclaimed by TRIM; however, even with TRIM, fewer free, programmable blocks translate into reduced performance.

HDDs are not affected by free blocks or the operation (or lack) of the TRIM command.



Power consumption

High performance flash-based SSDs generally require 1/2 to 1/3 the power of HDDs; High performance DRAM SSDs generally require as much power as HDDs and consume power when the rest of the system is shut down.

High performance HDDs generally require between 12-18 watts; drives designed for notebook computers are typically 2 watts.
