TSSDR TEST BENCH AND PROTOCOL
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, and Enhanced Intel SpeedStep Technology (EIST) has been disabled. Benchmarks for consumer testing are also benchmarks with a fresh drive so that not only can we verify that manufacturer specifications are in line, but also so that the consumer can replicate our tests to confirm that they have an SSD that performs as expected. We even provide links to most of the benchmark software being used; simply click on the section heading with the benchmark’s name.
Today’s analysis will be conducted using our Intel DZ77GA-70K test bench. Clicking on any pictures or benchmarks will open a more easily viewable high-resolution image. Our test system is comprised as follows:
|PC CHASSIS:||Cooler Master N600|
|CPU:||Intel Core i7-2600K|
|CPU COOLER:||Cooler Master Hyper N520|
|POWER SUPPLY:||Sliverstone Strider 600W|
|GRAPHICS CARD:||EVGA GT610|
|MEMORY:||Kingston HyperX DDR3 1600MHz|
|OS STORAGE:||Edge Boost Pro 7mm 240GB|
We would like to extend a TSSDR hat-tip to Cooler Master for providing the N600.
After initializing and formatting the Silicon Power Slim S80 240GB, it shows up in our disk management screen as the E: drive. It also shows as healthy and having 223.57GB of user-available capacity.
The software in use for today’s analysis is typical of many of our reviews, and consists of Crystal Disk Info, ATTO Disk Benchmark, Crystal Disk Mark, AS SSD, Anvil Storage Utilities, Iometer, PC Mark8 and PCMark Vantage. Our selection of software allows each to build on the last, and to provide validation to results already obtained. All results are displayed through screen capture of the actual benchmark’s results for better understanding by the reader of the testing process.
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 and power-on cycles the drive has experienced, as well as informing you of the firmware version of the device.
Crystal Disk Info verifies TRIM, NCQ, and that S.M.A.R.T. drive status and health reporting attributes are enabled. We were initially a little concerned with the fact that our review sample, although delivered in a sealed package, did not have a tamper-seal on the case. This raises the question of the drive actually being new or not, but Crystal Disk Info shows only 10 power-on counts and 0 hours, verifying that this is, in fact, a new drive.
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 read and write performance of various transfer sizes ranging from 0.5 to 8192KB. Manufacturers prefer this method of testing as it deals with compressible data rather than random (which includes incompressible data), which although more realistic to everyday use, results in lower performance results.
ATTO testing reveals read speeds peaking at 555MB/s, and write speeds peaking at 535MB/s. Write speeds exceeded the 500MB/s threshold for all transfer sizes of 256KB and larger, while the read speeds exceeded that same threshold for all transfer sizes from even only 16KB on up. These are excellent performance results for a value-oriented product.
