Show us your SSD performance

Here is a little story to add to your homework folder. The Vertex2 came out with the 34nm nand and performed very well and earned a great reputation. Somewhere around last November (when I bought mine) they changed to 22nm nand and quality suffered. They just didn't tell anyone they changed and used the same name and model #'s. There was a big blowup on the OCZ forums about it. The thing about it that some might question is--- They buy their nand from none other than Intel.

The newegg ratings reflect this problem also.

The nand/memory is Intel. The controller is Sandforce and was changed from the 34nm to 22nm not the Intel storage chips.
Went from Sandforce 1200 to 1500 series controller. I believe those are the right numbers.

Vertex2 early version. Looks like SF1227 on the controller chip.

Here are some interesting facts: http://apcmag.com/ssd-roundup.htm

To change the subject just a little, can someone explain why an SSD will not perform on a Dell? I have a Dell with an i3 and an H57 chipset. I've installed 2 SSds both aligned and in ahci and the best I can get is the same performance I see on a WD drive?

Can you quantify how you are measuring and checking for a change? I installed an 80GB Intel 320 series SSD into my work Dell Latitude E6400 and it made a difference that's easily measured.

I ran wei and scored 5.9 and ran AS SSD and don't recall the numbers but was extremely low. Everything was properly set up the same as on my other 2 desktops. I just assumed it must be something with the Dell propiatary stuff.

There is definitely something wrong - and I do not think that it is a Dell thing. My Vertex performs as expected in my Dell Inspiron.

Did you double check the alignment? SSD Alignment

Yes. I aligned and formatted it at installation using diskpart. Also checked the alignment after installation and made sure it was in ahci mode in bios. I have read in places on the internet where others had the same problems with Dells, but they were usually laptops. I guess it really doesn't matter. The Dell is a "In case of emergency" computer. I'll try again later.

(Almost missed the most recent posts, this is a note on the Vertex 2/Vertex 3/Intel/whoever question.)

Hard drive manufacturers have touted all sorts of benchmarks which make their drive look "better", on paper at least. Remember the ATA 133 hype? Real world you couldn't tell the difference between that and ATA 100.

I'm with WHS on this. Instantaneous access times are the whole point of the SSD performance boost to begin with. Add in reliability as a "value" factor and the other stuff is just numbers. :)

I've always seen better access times on Intel drives, (AS SSD) 0.075/0.114 on my X25-M 120GB and 0.092/0.076 on my X25-V 40GB.

From what I've seen/read in the last few months, I'm going with the Intel drives.
If OCZ can iron out some marketing and reliability issues, I will be happy to buy one.

Intel 320 series now have a 5 year warranty.

SSD failure rates
- Intel 0.3%
- Kingston 1.2%
- Crucial 1.9%
- Corsair 2.7%
- OCZ 3.5%

Have seen these numbers on several sites.

The X25-V is now in my Dell Laptop and running very well.
WEI 7.5
AS SSD is 301, not as good as when in my desktop 340, but the specs aren't near as good either.
You might try the Intel RST drivers from Intel instead of from Dell, not sure if it will make a difference but, I've been using them for years.
