OCZ ARC 100 SSD Review (240GB) – Consistency in a Value SSD


SSD Testing at TSSDR differs slightly, depending on whether we are looking at consumer or enterprise SSDs.  For consumer SSDs, our goal is to test in a system that has been optimized with our SSD Optimization Guide. To see the best performance possible the CPU C states have been disabled, C1E support has been disabled, Enhanced Intel SpeedStep Technology (EIST) has been disabled. Benchmarks for consumer testing are also benchmarks with a fresh drive so, not only can we verify that manufacturer specifications are in line but also, so the consumer can replicate our tests to confirm that they have an SSD that is top-notch.  We even provide links to most of the benchmarks used in the report.

Sean Webster Test Bench

This is an updated test bench and, as such, we would love to thank those who jumped in specifically to help the cause.  Key contributors to this build are our friends at ASUS for the motherboard and be quiet! for the PSU and cooling fans. We have detailed all components in the table below and they are all linked should you wish to make a duplicate of our system as so many seem to do, or check out the price of any single component.  As always, we appreciate your support in any purchase through our links!


This Test Bench build was the result of some great relationships and purchase; our appreciation goes to the below mentioned manufacturers for their support in our project. All of the components we use for testing and evaluation can be easily purchased at a relatively affordable price. The links provided below can assist in pricing, as well as availability for those of you who may find interest in our equipment.

PC CHASSIS: Corsair 650D
MOTHERBOARD: Asus Maximus VI Extreme
CPU: Intel Core i5-4670K
CPU COOLER: Thermalright Silver Arrow
POWER SUPPLY: be quiet! Dark Power Pro 10 850W
SYSTEM COOLING: be quiet! Silent Wings 2
MEMORY: G.Skill Ares DDR3-1866Mhz Memory


The software we will be using for today’s analysis is typical of many of our reviews and consists of ATTO Disk Benchmark, Crystal Disk Info, Crystal Disk Mark, AS SSD, Anvil’s Storage Utilities, PCMark Vantage, and PCMark 8. In consumer reports, we prefer to test with easily accessible software that the consumer can obtain, and in many cases, we even provide links. Our selection of software allows each to build on the last and to provide validation to results already obtained.


Crystal Disk Info is a great tool for displaying the characteristics and health of storage devices. It displays everything from temperatures, to the number of hours the device has been powered, and even to the extent of informing you of the firmware of the device.

OCZ ARC 100 240GB Crystal Disk Info

Crystal Disk Info shows us that the ARC 100’s S.M.A.R.T. data does not feature a working temperature attribute nor DevSleep support.  However, it does provide ample attributes for health monitoring of the SSD over its lifespan with gigabyte read and written values. It also shows us that it supports TRIM and NCQ.


ATTO Disk Benchmark is perhaps one of the oldest benchmarks going and is definitely the main staple for manufacturer performance specifications. ATTO uses RAW or compressible data and, for our benchmarks, we use a set length of 256mb and test both the read and write performance of various transfer sizes ranging from 0.5 to 8192kb. Manufacturers prefer this method of testing as it deals with raw (compressible) data rather than random (includes incompressible data) which, although more realistic, results in lower performance results.


ATTO shows us a high of 489MB/s read and 429MB/s write. The read speed surpasses the rated spec. of 480MB/s by 9MB/s and write is just 1MB/s shy of the rated 430MB/s.

    it makes me wants to consider them again.

      Well, considering MX100 is both cheaper and faster and on top of that offers hardware encryption i really see no reason buying this. It needs to come down on price

        Performance and features wise the SSD series is actually darn close to the Vertex 460 we recently tested and overall it is faster than the Crucial MX100 really. That MX100 will drop in performance fast once you start to really utilize that SSD, that’s not the case with this ARC 100 though.

        Yeah that kind of crazy consistency is not really applicable to the potential buyer, that buys value drives. Yeah, its nice to have great consistency, but then again, avarage user will never write that much and if you’re using trim aware OS, performance will always restore to its optimal state.

        So the way i see it; its 22€ more expensive and has 16GB less space (for 256GB class). Yeah i think pretty much everyone buying a value drive will go with cheaper “alternative”.

        But not the cleverer ones, I believe/

    the mx100 looks cant be bought for under £74 in the Uk and this can be picked up for £65

    Great Review. Thanks. It helped me.
