You need to have a recent, verified backup of your Windows partition before trying any of this. If you are a beginner, then please leave it well alone. It is straight-forward provided you are experienced enough.

Secure-erasing the SSD is a very fast process, upon issuing the command it is done in less than a second.
#SANDISK SSD TESTING SOFTWARE ISO#
You will also need unetbootin to convert the Parted Magic iso into a bootable USB stick. You can still do it using a bootable USB stick containing Parted Magic. Some manufacturers provide tools for secure-erasing but SanDisk doesn’t - and I hope this changes in future SanDisk releases, an included tool to secure-erase would be great. This will bring a used-and-abused SSD back to its new out-of-the-box state.
#SANDISK SSD TESTING SOFTWARE FULL#
SanDisk, we are waiting!Īt the end of the day, the only way to get the full performance back out of a modern SSD is to secure-erase it. Still, if SanDisk puts some effort into it they can produce a tweaked firmware that does the job at least adequately. Don’t expect miracles, like the Vertex 4 recovery figures on the above link, that model uses an Indilinx controller, not SandForce. I hope that SanDisk will produce a properly tweaked firmware soon with optimized algorithms for garbage collection, and with a TRIM that gives back the performance.

Currently the SanDisk Extreme suffers from poor firmware as you can see from the Degradation and Steady-State Performance tests here (this is the most recent test for the SanDisk Extreme): The efficiency of TRIM and GC varies between manufacturers. Of course the degree of the performance you will be able to get back by TRIM and Garbage Collection, depends on how full is the SSD, and how optimized is its firmware. Have a look here for a comprehensive review that showcases its equally strong 4K IOPS results for both read and write testing - which is something of a rarity: The great thing about the Extreme for me is its great out-of-the-box performance, which is at least on a par with other more expensive brands. Here’s a test I performed today that proves that this little program does work:ĭon’t forget to save screenies of your PRE-TRIM and POST-TRIM results for later comparisons. I managed to find a copy after a lot of searching, and I have uploaded it here: Remember, it is not supported for RAID configurations. It forces TRIM on the drive, but it is currently hard to find. Personally I use a free program ( ForceTrim) which was made available at the OCZ forums in the past.

SSD Tweaker Pro and Tweak-SSD both have such a function but only on their paid versions.

There are some software which allow you to manually induce the TRIM command. TRIM is initiated automatically by the OS after files have been deleted (Vista SP2 and Win7 only, WinXP doesn’t support TRIM). Performance recovery also takes place by the issuing of the TRIM command in Windows. This is done by the SSD’s internal Garbage Collection which is is built-in in the SSD’s controller and kicks in automatically when the drive is idle - it cannot be initiated by the user. Most modern SSDs will perform wear leveling and automatically recover at least some of their performance over time. This is even more evident on drives with SandForce controllers (like our SanDisk Extreme). The top performance that you see on various reviews online is based on brand new out-of-the-box drives. Out of the box all SSDs are fast but the performance will deteriorate over time, especially when the drive is almost full. It’s a german project, but the software also has english support (select it under the Language menu of the program). It provides more realistic results than CrystalDiskMark and it uses incompressible data for its test so don’t expect high numbers out of SandForce drives like the Extreme (which work faster with compressible data). Latest version is 3.0.1c, it’s free, get it from here:Īnother good free benchmark which is made specificaly for SSDs is AS SSD Benchmark.

Do a run, then choose Random (which is the default) and you’ll see the difference in numbers. Click File - Test Data and choose 0-fill or 1-fill.
#SANDISK SSD TESTING SOFTWARE PORTABLE#
I’d recommend for you to download the portable version as it needs no installation, just run the executable. You can easily see the difference between 0-fill/1-fill and Random benchmarks by using CrystalDiskMark. 0-fill/1-fill gives higher numbers so the companies use those to entice customers into choosing their products. When SSDs are advertised, the figures that you see are usually based on synthetic benchmarks using 0-fill/1-fill data, not Random. I wanted to provide some tips for novice users who may worry about the poor performance of their drives. I already own a 240GB SanDisk Extreme and I’m waiting for a second one to arrive tomorrow!
