Transcend was kind enough to lend us two of
their latest high performance consumer grade solid state drives for review, one
with 32GB capacity and another with 256GB capacity, both MLC based. Both
drives feature a 2.5" form factor with an SATA2 interface. These SSDs can
be fitted directly into a laptop that supports an SATA hard drive, but for this
this review, we will be using a desktop PC that supports SATA2 drives.
As we have mentioned in previous reviews of
SSD drives, running synthetic benchmarks on SSDs is of limited use, as they
rarely show how well the SSD performs in the real world. With most hard disks,
the main factors that affect performance are read/write speeds across the
platter, random access times, their burst speed and their cache size. As SSDs
use wear-levelling to try giving as even wear as possible across the NAND
blocks and also need to carry out an erase cycle on blocks before they can be
rewritten, these factors have a huge impact on an SSD’s performance.
For example, an SSD fresh out of the box
will perform quicker than an SSD that has been quick-formatted after several
months of heavy use filled to near capacity. A hard disk on the other hand
will perform exactly the same out of box as after even several years of heavy
use, assuming the hard disk’s mechanical functionality is still in perfect
working order and the platter does not have any defects.
So in this review, we start by carrying out
a small number of synthetic benchmarks, comparing it to an OCZ Agility, a
desktop hard disk, a laptop hard disk and against other SSDs for some tests.
The rest of the review involves a variety real world tests with a clean Windows
7 installation and again with an aged Windows 7 installation that has been in
everyday use over a year. Finally, we measure performance as the SSDs are filled
up to capacity with small files.

These SSDs were shipped to us in shrink-wrapped
retail packaging, as shown in the following images:

The only difference with the content of the
256GB model is the drive itself. Both SSDs were enclosed in a static-proof
bag, as shown at the upper right of the above image.
The retail bundle consists of:
- Transcend 2.5” SATA2 SSD.
- 4 mounting screws.
- A quick installation guide.
- Warranty guide (not shown.)
- Transcend product guide (not shown.)
The following shows close-ups of the label
side of the 32GB and 256GB SSDs:
On the bottom of the SSDs, we can see the
model numbers, serial numbers, the power handlings and the SATA connectors,
along with various certification logos. The reverse side is plain black with a
holographic Transcend logo.
Both SSDs appear to have hard plastic
At this time of writing, the only
specifications we were able to obtain were those printed at the upper left at
the rear of both boxes. Even still, these specifications don’t appear to be
accurate as both boxes show the same specifications in this table and the write
speeds mentioned do not match up with any of the write speeds mentioned on the
front of the boxes! We were also unable to find detailed specifications
The following shows a close-up of the
read/write speeds mentioned on the front of the box for the various models:
The following shows a close-up of the SSD
specifications table at the rear. This table is identical on both boxes:
As there is no clear mention of the controller,
we contacted Transcend and they mentioned that both SSDs use the JMicron 612
controller and that the 32GB model is also supported by Hynix.
Now let’s head to the next page where we
will look at our test PC and testing procedures…
