Doesn't matter as long as the median is 100.

Thanks for replying to my specific question ... appreciate that.Thanks for your reply ... unfortunately it does not answer my question. My question is very specific, i.e. "will upgrading to an SSD have a significant performance improvement specifically for CS6, LR 4.4 & Final Cut Pro, after they have been launched?I am aware that SSD will significantly increase the start up times and read/write times but I have a specific question regarding the the performance of Adobe CS6, Lightroom 4.4, Final Cut Pro etc, with an SSD:
I currently have a Mac Book Pro Mid 2010 (OSX 10.8.3) with 16 GB DDR 3 RAM, 750GB HDD, 2.9 GHz intel Core i7 processor, and all of the above programs work perfectly, I have no issue at all, but what I want to know is will upgrading to an SSD will have a significant performance improvement after those programs have been launched?
It is a little like a DSLR, there are many components that make it better.
I am no fan of anything "Apple" and I recommend the high end Lenovo or Dell machines for heavy image, engineering apps and HD video etc.
That aside, it will give you a boost upgrading to an SSD if all the components are correctly in place and aligned. The CPU plays a major part, the video card again is extremely important, your RAM and the type of RAM etc. Plus a lot of people forget the bus, if you connect an SSD to a SATA 2 bus then performance will be limited. I think 3 (GB/s) is the latest (not sure though), so no matter what the SSD claims is the read/write speed if your laptop cannot handle those speeds you just won't get them
My laptop currently has two SSDs in it and could have four, but for me the main advantage with SSD (apart from the speed) is how quiet they are. Really makes a difference to your day if you work somewhere very quiet.
So would I recommend an SSD, definitely. Do I recommend upgrading a current laptop from a 750GB spin drive with all the headaches that that entails? That is the major question imho. Personally, I probably would wait until you want to upgrade your entire laptop. But if you are comfortable technically moving from a 750GB spin to a SSD then why not.
I also use a Dell Alienware Mx14 (2012 version Core i7) which has a dedicated graphic card, yet the MacBook Pro outperforms but my question, about SSD replacment, remains the same for either systems.
It will help with program start up but after the program starts for the most part everything is in your RAM. So for the most part no additional help after start up. Write should be faster so that may be the only noticeable increase.

SSDs are great for boot drives and program installs. For data storage, it can still be expensive and you must be religious about backing up. (A good idea whether using standard HDD or SSD)
Haven't heard of this "EQD" brand. Would it be just as good as a Dell IPS 24", which often is on sale as well?
how much image difference would this have versus a 70-200 2.8L IS II with a 2x converter? you'd have 140-400 f/5.6 w/IS-

SSD capacity continues to increase ...
If you're going to rent a 70-200, don't get the f4, go for the f2.8, the sharpness is amazing. You also may want to consider renting an L Prime, as they also produce good results.My friend doesn't want to use my bodies because he wants to be able to put all the good ones that he took in his personal portfolio. Weird but he doesn't want to get his clients hopes up by using a body that he doesn't have. Its his personal preference.
Yet he wants to use a rented lens?
So if we go for the f/2.8 should we get the non-IS or the IS version?
Lenses aren't a big deal for him. He can rent all the lenses he wants. It's the body that he really wants to wait for. He will not shoot with a FF camera until he has his own. He's set on that ideology. I've tried telling him that 5Dc's aren't that expensive.
the AF from the 7D is more or less wasted on baby shots.
So basically you're saying the ISO50 setting only affects metering, not sensitivity?
If I set up at ISO100, meter dead center, take a photo, and then drop to ISO50 with all else being equal, I'll see the meter move one stop to the left, but the actual picture will be the same?
Metering and the ISO value recorded in the metadata. Assuming you're in manual mode (since in an AE mode, the change from ISO 100 to ISO 50 will result in a compensatory change in aperture or shutter speed to maintain metered exposure), the RAW data file will be the same - an ISO 100 exposure. The jpg file will be pulled down a stop, and when you open the ISO 50 RAW file in an editor, it will display darker than the ISO 100 file, because the RAW editor/converter will pull the exposure down based on the ISO value in the metadata.
I see lots of confusion here.
Except for the EXIF flag indicating exposure, the RAW file you'll get with ISO50 @ f/8 @ 1/400 will be exactly the same as the one you'll get at ISO100 @ f/8 @ 1/400. The only difference is that, if the camera's meter tells you that the proper exposure is ISO100 @ f/8 @ 1/400, it'll tell you that you should be exposing the ISO50 shot at f/8 @ 1/200. And, of course, the RAW developers are programmed to invisibly apply a stop of digital pull to the ISO50 shot.
There will be a difference between ISO50 @ f/8 @ 1/200 and ISO100 @ f/8 @ 1/400 -- and it's that difference that people almost always compare.
BUT!
There won't be a difference between ISO50 @ f/8 @ 1/200 and ISO100 @ f/8 @ 1/200.
And, of course, there will be a difference in the RAW files between ISO100 @ f/8 @ 1/400 and ISO200 @ f/8 @ 1/400.
Hope that helps clear things up....
Cheers,

P.S. A very similar thing happens with highlight tone priority, except in the opposite direction. The RAW files for a given shutter and aperture will be identical between ISO100 and ISO200 + HTP, but the meter will be different. b&
I've not noticed a marked difference between 100 and 160, but this chart is worth a look.

Indeed. All the recent/current Canon bodies except the 1D X have that sawtooth pattern.
But I am not sure of my facts on these 'non native' ISOs. I've read that people claim there is less noise at ISO 160 than 100, but I have not found this to be the case. However I have found that ISO 50 (L) can give smoother data than 100.
Tolerance buildup can cause lenses to be tight or loose on the mounting.
