The SSD Review The Worlds Dedicated SSD Education and Review Resource | 
TEST BENCH AND PROTOCOL
Our analysis today will be conducted with our new Asus Z77 Premium Test Bench.
In testing, our main objective is to obtain results as pure and as accurate as possible and we want to ensure that no anomalies slip through. Simply put, we want to provide you with the absolute best results the tested hardware can provide. Repetition in testing is standard and, if necessary, we may conduct specific tests in Windows 7 safe mode to ensure the OS has little to no influence on the end result.
In order to validate and confirm our findings, testing is supported by industry accepted benchmark programs. All results are displayed through capture of the actual benchmark for better understanding of the testing process by the reader.
We would like to thank ASUS (P8Z77-V Premium
), Intel (Core i7-3770K), Crucial (Ballistix), Corsair (H100) and Be Quiet (PSU/Fans) for supporting the build of our Z77 Premium Test Bench.
BENCHMARK SOFTWARE
The software we will be using for today’s analysis is typical of many of our reviews and consists of ATTO Disk Benchmark, Crystal DiskMark, AS SSD, Anvil Storage Utilities and PCMark Vantage. We rely on these as they each have a way of supporting one another yet, at the same time, adding a new performance benchmark to the total picture. Much of the software is free and can be downloaded simply by clicking on the linked title.
SSD COMPRESSION AND TESTING FLUCTUATIONS
All SSDs are not created equal and many new SSD enthusiasts realize that when they test their new drive to confirm specifications and ensure all is in order. LSI SandForce controlled SSDs, as in the Corsair Force GS 240GB SSD we are testing today, use compression techniques in storage whereas many others do not.
This creates a bit of confusion when enthusiasts test the drive with random data through benchmarking programs such as AS SSD and Crystal DiskMark. The results seem to be lower than the listed specifications.
Crystal Disk Info provides some excellent information about the SSD itself to include its health, product information, power on information as well as the characteristics of the SSD. We can see that the SSD is capable of TRIM as it is not greyed out as with AAM.
Doesnt the Sandisk Extreme SSD 240GB use the same toggle NAND??
The identification numbers do not match that of the extreme. We have word that the answer is no but are hesitant to commit until SanDisk can confirm.
when will the days of drive makers OVERQUOTING the size of their drives, if I buy a 240GB drive, I want to use 240GB not a byte less!
Well, there is 2 answers to that question, its not only a ? about them deliberately putting incorrect values ??on, if i remember right its also the hole bits to byte or the other way around, but i got a IT education and a CCNA,but i cant remember the all the dif. values, other than a byte is “Normal” 8 bits, if u dont also count the “overhead”,then it can b 9 or even 10,hehe,anyways,the companys that sell u a HD define a megabyte = 1,000,000 bytes, but some OS/Programs/Systems(like Windows/Fdisk/Bios) say that a MB is = 1,048,576 bytes (if u dont belive me, go find a big file and right click on it, windows will say its like 6.5GB, but then in ( ) it will say its = 7.082.606.592 byte, so there u have why when they say the HD is 1TB, and u format it,and right click on it,it will never ever say u got 1 TB free! Hope u could use my answer, else try and google “what is a byte” or “Byte to bit converter” or what ever size u wanna get the “real” value of, like “TB to GB converter”!

i have just put one of these drives into my dell xps 17 l702x and when i run crystaldisk im only getting about 45MB/s 4k write. should i be concerned? your help would be much appreciated
Conduct the test while your system is in safe mode and see the 4k result. It shoud be higher and this will let you know whether it is SSD/install related or he result of the OS environment. It is not Crucial that it be higher but we like to see it. Did u migrate or do a fresh install?
Thanks for quick reply. I did a fresh install of windows 7 and followed the optimization guide on here. My atto result is a tad off aswell. Only got 488MB/s write although the read hit 552. Just wondering if different systems with different hardware would affect the result
Have you followed my advise and tested in Safe Mode?
Yes I tested in safe mode with the same results. Not sure what it could be.
My sequential write on crystaldisk only hovers around the 200 mark too
I have Silicon Power V60 240GB for testing at the moment, it has the same Toggle Mode SanDisk Nand Flash modules found inside the Force GT, it is showing great performance up till the moment as well, with only 202 $ price tag @ Amazon. This is a real deal 🙂
