I thought my speeds were great but those are amazing! As usual with Intel there are anomalies: your 4k marks are a bit lower but ypur earlier write speeds are much higher!
I've also leanrt a lot from this discussion thread - the main thing being that you can get a heck of a lot more help from the community the you can from Intel! Thanks to everyone who has contributed and I will keep following this even though I've moved to RAID.
I wanted to report back to let everyone know that I am now in 6Gbs bliss. I last week I replaced my PWG2 drive with a new PWG4 drive and I have been running at 6Gbs on both drives ever since. Thanks everyone for your comments and suggestions. I am now thinking about what these drives would be like in RAID 0!!!
That's really good news! So it would seem that having different firmwares is the cause? I had suggested this to Intel but they dismissed it as a possibility. Maybe now they may look into it properly? Did you swap the drives at your own cost or was it an exchange? I think I may now contact Intel and insist they replace my PPG2 with a PPG4. Although I an currently using RAID I may want to change back to AHCI in the future. So Mario, if you are reading this, expect a call when I get hack to the UK next week! Bannon, I think you'll be impressed with the RAID speeds - they're pretty amazing! Any chance you could make one last post showing a benchmark in RAID? I'm glad it's worked out for you.
I had recently added an Intel 510 SSD 250GB (PWG4 firmware) to my system and this problem started acting up too.
CPU : i7-2600
Mobo: Asus P8P67 Pro (1850 BIOS firmware)
RAM : 4 X 4GB Corsair Vengeance DDR3-1600 1.5v
SSD : Intel 510 SSD 120GB (PPG2 firmware) + Intel 510 SSD 250GB (PWG4 firmware)
GPU : 2 X Asus GTX460 DCU TOP 1GB
PSU : Coolermaster Silent Pro Gold 800W
I have iRST 10.6 running and the latest INF driver installed. The drives are randomly going back and forth between 6Gbps and 3Gbps. When I only have the 120GB installed, it is fine. So now I have a very expensive Intel 510 SSD 250GB as paperweight.
Really sorry to hear that you've got this problem too! I went back to Intel and said that even though I am using RAID I wanted the issue fixed so I could use AHCI if I wanted to. That was about 4 weeks ago and I have contacted them at least 4 times to ask for my drive to be replaced. Every time they avoid answering the question and just say that they are looking ito it. I finally contacted the retailers who I bought the drive from and explained the problem to them. The retailers have asked me to retun the drive and they will contact Intel to see what is going on. They reckon Intel will respond quicker to them and even if not, they will replace the drive.
So I recommend gettig in touch with your retailer and telling them about all the cases reported here with this problem. I think Intel have been pretty useless so far. Perhaps they are working on a firmware update but there is no excuse for it to be taking so long. I certainly won't be recommening intel drives after this.
All the best,
After over 7 weeks of INntel doing nothing and making poor excuses I took advice from the Trading Standards Office (via Consumer Direct) here in the UK. They directed me to approach the retailers which I did (see above post). I also informed Intel that I was seeking advice and also wished to make a complaint regarding the awful level of service from Tech Support. I was told to write to firstname.lastname@example.org which I did.
Ever since then my messages are always answered thus:
Dear Mr. Pugh.
Thank you for your communication below, the contents of which are noted.
We have referred your mail to our legal department for consideration and will contact you shortly.
Good morning Mr. Pugh.
Thank you for your mail below.

As previously advised, as soon as we receive a reply from our legal department regarding your previous submission, we will contact you accordingly.

And when I try to contact Tech support to see if they have made any progress (hopefully they will release a firmware update so I don't have to send my drive back to the retailer) I get this response:
Dear Mr. Pugh,
Your case is currently being investigated by Mr. Jim Morris and the Intel Legal Team as advised to you by Mr. Morris on Friday 23rd September.
Please direct any further communications regarding this case to Mr. Morris at firstname.lastname@example.org as we are unable to comment further at this time whilst investigations are taking place.

If this isn't an example of stonewalling then I don't know what is. Quite incredible for a company like Intel. I suppose us little people don't matter and if we make too much fuss they just start using terms like "legal department" in the hope that it will make us go away. Unbelievably bad!
I still haven't heard anything more from Intel. It's now been 8 weeks since Intel were first informed of this problem. I guess they just don't give a sh*t?
It looks like they don't think it's important enough or not enough people have the problem for it to be worth the effort. I recommend just taking the drive back to the retailer and asking for an exchange. It's been proved that there is an issue so they shouldn't give you too much trouble. Howeber, I thought the same of Intel but they've turned out to be utterly useless!
Originally I had hoped it was a firmware conflict issue. After Intel sent me a new replacement Intel 510 SSD 120GB drive with PPG4 firmware, at first I had posted it was fixed cos I checked the speed a few times and it was 6Gbps. However, after running Windows Update and installing other programs, I felt the install speed was slower and when I check again, it still had unstable random switching between 6Gbps and 3Gbps with my Intel 510 SSD 250GB with firmware PWG4.
At least the random freeze up with the Intel 510 SSD 120GB appeared to be fixed. I guess it was caused by a faulty/corrupted sector which I found using HDTune Pro. The new replacement SSD was scanned thoroughly and result was perfect. I haven't froze up in a couple of days of installing programs and patching.
I will move one of the SSDs into a laptop, since the SSD speed is okay at 6Gbps with only one Intel 510 SSD configuration.
