We are all pretty used to reading reviews on ‘state of the
art’ high performance SSDs here at Myce.com, and we enthusiasts usually demand
the latest and greatest from a performance perspective. Having said that, there
is a massive market for users who are still running an operating system from an
old and slow HDD, and who would like an entry level SSD to breathe new life
into an older PC, or for that matter would like to boost the performance of a
new PC which was supplied with an HDD rather than an SSD.
Enter the budget or value line SSD. So what is the
difference between a ‘budget’ SSD and a ‘state of the art’ high performance
The most obvious difference is the price. Budget SSDs by
definition cost less than a ‘state of the art’ high performance SSD. So how can
the manufacturer reduce the cost of the budget SSD?
Use cheaper components. State of the art high performance
SSDs will use the highest quality ‘binned’ NAND, and the top of the line SSD
controller. The budget SSD may use lower quality NAND, and may simply slow down
the clock rate of the SSD controller, thus slowing down the write rate of the
SSD. Slower writes mean better NAND endurance. So cheaper NAND can last as long
as the higher quality NAND, if you take care of how quickly you program the
NAND. Slowing down the SSD controller will of course reduce performance, but as
a bonus, the SSD controller will consume less power.
Another way of reducing costs is to include fewer
accessories in the package. You can remove the 3.5 inch to 2.5 inch converter
bracket, and fixing screws. You can also remove the bundled software, and
reduce the term of the warranty.
So we end up with a cheaper but slower SSD. Sequential
reading and writing speeds will generally be substantially slower when compared
to high performance enthusiast SSDs, small file random performance will also
see some slowdown. Having said that, you can still have a very fast budget SSD,
if the manufacturer gets the performance profile right.
Target the market segment that is likely to purchase a
budget SSD, then adjust the performance profile of the SSD to meet that market.
In my opinion that market will most likely be casual PC users, whose PC
workloads are likely to be quite light when compared to the semi-pro user who is
more likely to demand the performance offered by a ‘state of art’ high
So how do you tune the performance profile of a budget SSD,
so that SSD feels just as fast to the casual user as a state of the art SSD?
If you have studied mainstream user workloads, you will find
that pretty much everything happens at very low queue depths. As low as a queue
depth of one or two, so tune the performance profile for high performance at
low queue depths will result in an SSD that feels just as fast to the casual
It has been a while since OCZ released a budget SSD, but
that is the market segment where the new OCZ ARC 100 series of SSDs is aimed
at. The ARC 100 further consolidates OCZ’s transition to all in-house
components, in this case the transition to Toshiba A19 MLC NAND. The next SSD
to make the transition to A19 MLC NAND will be the Vector 180, due later this
In 2015, OCZ expects to launch a new product family that
will cover everything from mainstream to workstation class SSDs, with a new
product family called JetExpress. Whilst there is no information currently
available for this new family of products, I can speculate that JetExpress will
cover PCIe (hopefully NVMe) and also include SATA Express variants. See the
Right then, let’s get back to the ARC 100 SSD series. There
are three capacities available, 120GB, 240GB, and 480GB. The version that I am
looking at today is the 240GB version, which OCZ very kindly sent me for

Now it’s time to take a look at the drive itself and what it
came shipped with.
