SLC, MLC, and TLC are different types of Nand, each with different physical properties, you can't "flash" one to another. This renders the idea impossible although the concept is intriguing.
1. If you write more than 50% of the free space on the drive all at the same time, it will slow down temporarily until the write is finished. Once the write is finished the drive will take a moment to perform some "cleanup" and then will return to the faster state.
Example: You have 75GB free...
There really isn't anything to "fix" because 3 weeks or 6 months from now you might be down that 20MB/s again through your pattern of usage. Very few drives stay at the very top of their performance 100% of the time. A secure erase will reset everything to out of the box performance though.
We may not be able to get it back without a secure erase. What is the date of your drivers? Right click the line above (in device manager) and select driver and see the date it was published.
You do have a fairly old chipset and even with newer drivers, you may not get the speed. Newer drivers...
They are absolutely related in a fixed way.
IOPS x (the file size you are measuring the IOPS for) = throughput. Change the IOPS and you change the throughput, change the file size and you change the throughput.
@ Berryracer,
His partition is aligned, it shows in AS-SSD as fine. He is using a SATAII SSD and motherboard, you are using a SATAIII SSD and motherboard, you are going to blow him out of the water on AS-SSD scores.
He is also using a SF based SSD which in AS-SSD scores lower in writes because...
Yes, the Windows Toolbox can't update an SF based drive when Windows is running from it. Bootable tools allow the drive to be secondary and update anything.
For the OCZ drive, use the bootable tools: http://www.ocztechnologyforum.com/forum/showthread.php?105168-NEW!!-OCZ-Bootable-Toolbox-PC-Edition
Just make sure you are in AHCI mode, you won't have to worry about drivers this way.
Because of the driver listed in AS-SSD. "asahci64". When connected to the Intel SATA3 ports and the proper Intel RST drivers are installed, the driver says "IAstorA"
You have the drive connected to the wrong SATA ports. You have them on the ASMedia SATA3 ports and thus you have lower performance.
Connect the drive to one of the 2 Intel SATA3 ports.
The 560/430 benchmark is also done with ATTO, not AS-SSD.
It is not common for the SSD to develop bad sectors.
It is common that new Nand may have some, which are found and noted during the initial manufacturing and bad block scan. Which is what the OP is most likely seeing.
The only thing to be concerned about is if the numbers grow in a short amount of time. If you check on a weekly basis and the numbers don't change, you are probably fine. If, after a week, you see changes, there is probably an issue.
I have never done anything to prove it, but it is my belief that the Intel driver somehow uses CPU cache rather than solely using RAM cache.
So, when you disable C1E and in this case get a core to do something else like Prime95, you get better benchmarks. I still feel this is just a synthetic...
The warranty is also only 3 years, if you purchased in 2008, your warranty has expired. Email me the details of your RMA. eryder at ocztechnology dot com.
Thank you.
Mfusick,
Did you enable write caching in the IAstor utility?
Did the benchmark for 4k's go up? That is all that will really change. What kinds of numbers are you expecting from AS-SSD with 2 in RAID0? and what part of the benchmark do you think is slow?
Feels slower, while doing what?
Yes, you have to be in RAID mode, of course.
Here is what you have to do, then find the IAstor utility over by your clock in the tray. Open the utility and make sure write back caching is enabled.
Write caching is disabled by default with the Intel RST driver.
Open the IAstor utility and enable write caching on the array. You need to disable the Windows caching first under disk drives in Device manager (check the 2nd box under policies) then open the IAstor utility. That will improve the...
You want to update the bios because it may help with memory compatibility. You say it is crashing now, so an update to the latest bios may resolve the crashing.
If it doesn't, then run memtest on your new memory to see if it is possibly faulty. The other factor is that the system may not be...
That update is for systems with an SSD installed to them from the factory. This is not an update for the X120e itself, it would update a factory installed SSD's firmware.
What you are saying is that when you put the SSD into the machine, it doesn't see the SSD? Where are you looking to see the SSD?
No, Groberts101 is not employed. He does get a drive, but he receives no monetary compensation. He is a beta tester, if that counts as employed in your opinion, so be it.
I want to clarify 1 thing. SandForce writes 100% of the firmware for their controller. OCZ nor anyone else has anything to do with the firmware that comes for those drives. There is no amplifying of any firmware.
Chipset, although Matrix was out way before Windows 7, you might have to try the "oldest" version of RST.
You can try the newest version too, it may show better performance, but you might pay lose some stability.
I should also note that with every SSD I have tested, platform makes a big difference. Laptops ALWAYS underperform compared to their desktop equivalents.
I have a Sandy Bridge Dell Laptop and when I bench any of our SSD's, the 4K's are lower in the laptop compared to P67/Z68 and X79/Z77 desktop...
If you are in AHCI and using the MSAHCI driver, that is good. To improve 4K performance, install the Intel AHCI drivers for that board. Which, are going to be quite old, but should give SOME (maybe 1-2 MB/s, maybe 10) increase in 4K.
Those drivers should be on the download page for the laptop...
GM965 chipset does not have a proper AHCI mode. Check your device manager under "IDE ATA/ATAPI controllers" is there anything about AHCI listed there? Like "Standard AHCI 1.0 controller"?
