SSD Write Speed Cut In Half?

I installed a Phoenix Pro 120GB G.Skill SSD a couple days ago. Was a little rocky at first, but I finally got it running. Once I got it running it was amazing. Boots into Windows in about 12 seconds. I ran a bench to check speeds and it's was within acceptable range due to the limitations of our chipset. One thing that has alarmed me is that the write speed has been cut nearly in half. I ran the bench about 4 times, and did 3 passes of 50MB. I was getting nearly 140MB/s random write speeds, but now it's around 80MB/s. From what I read, sounds like a secure erase will get me back up to speed, but what a pain in the a__ . And then, will it only last a couple days like now? I've done all the tweaks posted in this forum. Please help!

 

Shot in the dark but drive space is a big factor on speed. How much space do you have left out of your 120GB.

 

85GB, or about 75% free space

 

I would do some research on this as the SSD's are so new, if you did not have a hardware failure on the drive then it may be nothing more that a software issue, or conflict with another driver . Have you tried calling the tech support for the drive. They may have a fix and and know what is happening to your drive. I would do that straight away before I did anything else like RMA it or any major reloading of the system.

I do not know how many times I have out smarted myself on issues like this . Only to find out later that there was an easy fix just a question away.

 

Seems it's just the random writes taking a huge dive. I haven't changed anything from the initial install as far as drivers go, so if there was a conflict, it would be right out of the gate, which is not the case here.

I did a secure erase, and nothing changed. Still halved random write speeds.

 

I figured it out, had to secure erase. Problem was finding one that allowed me to erase. HDDErase and Gparted would not allow me to secure erase. HDDerase would not detect the drive, and Gparted would not secure erase. Would say permission denied. Found one called Parted Magic that worked perfectly. Now I'm back up to speed.

 

Glad you got it working. At first I thought you might have switched battery profiles. If you optimized high performance but bot your other profiles that would affect your speeds (assuming you were NOT in high performance when running the test, still I've found profiles only affect my speeds 10 Mbps or so). Other than that I didn't have any ideas. Your benchmark numbers will be closer to the factory specs if you change the crystal settings to 0 or 1 rather than ransoms. Also for me ATTO bench comes almost identical to the factory specs (285/275), I think it gets 275/255. Another curiosity is that you bootup in 13 seconds. From power on to full windows takes me 34 seconds. My OCZ Vertex 30gb only took 29 seconds. I have about 39gb used on the drive. Also newegg refunded the 9$ shipping I paid to RMA so that was nice. Which optimizations did you run?

Did you do a clean install originally or a drive copy? I read at gskill you only want to do a fresh install as a copy will reduce speeds (mainly if your sectors are not aligned, windows 7 does it automatically on a fresh install). I did a fresh install so maybe that why I dissent have issues.

 

I only run it in high performance mode. I did all the optimizations for our particular chipset, and all the SSD ones in your post in another thread. I get only slightly better speeds after all that. I also did a fresh install, but I initialized and formatted the SSD in Windows prior. The 12 seconds was when I first installed and had no PW to input, and i was just counting like one one-thousand, two one-thousand, etc. Now it's closer to about 25sec. When I restart, its so fast, Steam still thinks I'm logged into another computer, lol
