I doubt you would be able to tell the difference if you tried both side by side. We are probably talking about milliseconds, even nanoseconds in everyday usage.
How fast is your SSD, and when did you buy your MacBook Air?

So I dedided to run few tests on my MBA 13" Ultimate with that Samsung SSD.
AJA System Test gives values already seen here:
Write 210.4 MB/s, Read 260.9 MB/s
diglloyd DiskTester (sequential suite):
Averages for "Macintosh HD" (2GB/start, 2 iterations)
Transfer Size Write MB/sec Read MB/sec
32K 88.7 102
64K 100.7 116
128K 136.4 163
256K 165.4 205
512K 186.1 236
1MB 192.6 255
2MB 197.6 260
4MB 206.3 269
8MB 209.2 275
16MB 210.6 278
32MB 211.2 280
64MB 211.4 280
128MB 211.7 281
256MB 212.6 281
In real world I don't really have any feeling of any noticeable speed gain over previous models.
Actually I've got some bad feeling regarding the random write performance though it's just a feeling.

I bought mine less than 2 weeks ago. It should be noted the correlation between this SSD change and when the Apple stores started carrying 4 gig RAM models. That is when/why I bought mine.
People who are saying that they just bought theirs and yet it has the Toshiba that probably means its been sitting in the back stock room since before they made this change.
I am not sure how Apple will/would respond to this because it is a pretty substantial difference. Its the difference in shaving a few seconds off functions, and that is similar to paying for the upgraded processor for example.

the only post i've seen that makes any sense. most are just i'm upset mine is the slower drive blah blah blah. I can understand wanting a a faster drive, but will you see any difference?
what if the new drive writes slower randomly, so while you can obtain sustained higher sequential speeds, you'll be slower in many other tasks???
micro sd cards suffer the same issues. for example if you want to run android off a sd card you'll do much better looking into sandisk class 2 and 4 cards vs. any class 6, 8 or 10 cards. This is because random r/w is awful on the higher class cards vs. sandisk when running android of sd card. Yes, we don't run android but the same reasoning applies here.
personally, i'd want faster sequential r/w since i don't normally do large file transfers on my machine. When I do, a few extra seconds won't kill me. I'd like faster overall perf.
my 2 cents.
Hey.
So I bought my 1.6 GHz 11.6" with the 128gb HD and 4gb RAM on Dacember 22nd.
With that 4gb file size I ran:
Write: 206.9
Read: 262.5
Someone should make a survey monkey for this.
Make fields with size of computer, size of HD, amount of DDR and then write/read speeds; and CPU

alex, open up console after you run the AJA test and do a screen shot of that results posted to console. I ask this because I am seeing different results for me posted in console from the AJA test.
Just received my refurbished 13.3", 1.86GHz, 4GB RAM, 128GB SSD MBA in the mail today and I have the Toshiba SSD, and I honestly do not care one little bit. The speed of the MBA is out of this world. I've been using PC's with hard drive's my entire life, the fastest HDD I've had only being a 5200RPM HDD, so to me this is an extremely big change and I LOVE it!

Go calibrate your battery
Damn you lol.
Nah, I'm just kidding. Lol, but anyways, I am trying to calibrate it, but I'm still killing the battery lol. Funny because if this was on my Windows laptop, I would've been able to kill the battery in 10-15 minutes tops by just browsing a few websites with some tabs open.

that's cuz your windows laptop was a pos. my thinkpad lasted just as long if not longer than my 13 ulti.
That's true, but how much was your thinkpad? My windows laptop was $379 lol... possibly lower.

i've just checked and i'm stuck with the toshiba driver ah well. its alright, MBA's still fast enough for me - as compared to my faulty macbook pro 2008
i knw this is off topic, but are the airs getting sandy bridge processors in the next upgrade?

No one knows. Nothing has been confirmed.

Ultimate MacBook Air 13 (bought yesterday):
180.9 / 207.7
Revision: CJAA0201
So it turns out I was sold an older revision, right? That's why it's slower, right? I'm mad!!!
Should I have asked the sales person to pull out the latest revision? Is it even possible to identify one?
Jeeze Louise,if this makes you mad, you are going to have to sell it, unless you can look past this "problem"

My refurb has the ? Version, I just don't care, I am totally in love with my 11" MBA

New 11"
I have a 1.6 GHz 11.6" with the 128gb HD and 4gb RAM which i bought off the apple store via phone and i have the toshiba SSD, Honestly does anybody know what the difference side by side would be for different tasks? are we talking 2 seconds or 2 milliseconds? only bought this in feb, clocked out at 182, 205.

I dont think you will see major differences on the order of 2 seconds vs 2 miliseconds.
The question is...do you want the better spec'd drive and are you willing to make a return to get it. For me, I would return it (if within the 14 day return) for the better spec'd SSD.
ssd
So does the ssd only affect the download speed??? or does it affect overall system performance? like surfing the web for instance?

It theoretically affects anything that access disk. However no matter how much you try to time times with a stopwatch, you will never be able to measure the difference. It's too insignificant to worry about. Just enjoy your new Mac and don't worry about it. Even if you return this one, there is no guarantee that another one won't have the same brand SSD.

Not sure if this was mentioned before but according to Techreport the Samsung 470 doesn't have very good Garbage Collection. (source). While the Kingston V+ (Toshiba controller) has very good GC (source: Anandtech).
So those with a TS SSD may not be unlucky after all.
