The two key parameters that go in favor of Solid State Drives (SSDs) when
compared to conventional Hard Disk Drives (HDDs) are that they offer better
read/write speeds and high reliability. Having said so, many notebook users were
not keen on switching to SSDs for they didn’t offer large storage capacities.
And we know any standard 2.5” notebook HDD offers upto 500 GB of data storage.
Now Transcend has launched a 2.5” SSD which offers a respectable 192GB storage
capacity and has SATA-II interface which makes it compatible for notebooks.
Given the capacity, it can lure notebook users to switch from standard HDD to a
SSD to get better performance and reliability.

Price: Rs. 37,000 + Taxes (2 yr. Warranty)

Meant For: Mobile users
Key Specs: SATA-II interface, NAND Flash chip, built-in Error
Correction Code, RoHS, 1500G Shock Resistance
Pros: Incredible read/write speeds, light weight
Cons: flimsy packaging

This Transcend 192 GB SSD is made of NAND flash memory, which has no moving
parts. Due to this , it offers high reliability over standard HDDs as it won’t
be susceptible to mechanical failures arising from vibration or shock. HDD on
the other hand may crash or its magnetic disk can get damaged from shocks as the
writing heads can scratch the disk’s magnetic surface. The SSD also has a
built-in feature of ECC (Error Correction Code), which ensures accurate data
transfers. The drive has a Mean Time Between Failure (MBTF) rate of 1 million
hours and can resist shocks of upto 1500G, which shows the reliability of the
drive. For a notebook, power drawn by a hard drive affects the battery life. A
standard notebook HDD draws between 5-7 Watts during write operation while
Transcend SSD draws just 2.9 Watts. This difference can result in increased
battery life.

Performance
The main benefit of using a SSD is that they offer high data transfer rates and
negligible latency (access time). Therefore a computer equipped with SSD will
boot up faster and the system’s responsiveness will have noticeable improvement.
We tested this drive on Intel Core 2 Duo based machine with 1GB RAM. SSD is
meant to perform better than HDD, and to show the performance gap we compared
this SSD’s performance with a standard 5400 rpm notebook hard drive. We ran the
HD Tune benchmark to evaluate performance, and it gave astounding average
transfer rate of 132.3 MB/sec with an access time of 0.2 ms, while the HDD had
clocked average transfer rate of 64.4 MB/sec with 18.1 ms of access time. We ran
the Business Disk and High-end Disk Winmark tests of the WinBench99 suite, which
are used to check a drive’s throughput for business productivity and high-end
applications. Transcend SSD scored 30.3 MB/sec and 57.4 MB/sec respectively
which is much greater to the scores of the HDD.

Bottomline: The SSD with its low power profile is ideal for notebooks
as it will make them more energy efficient, while delivering better performance,
but then very few would be able to afford it.
