Any limitation to FFT calculation for large sampled signals

Hi,
I'm finding FFT of signal .
Sampling frequency is 1KHz and sampling freq is 50MHz
Number of samples =fs/f=50000.
For these many samples is it possible to find FFT?
Or any limitations?
Thank you

Example below with 5e7 (50,000,000) points -- 1000 times more than you were asking for. The number you are asking for is no problem at all.
data = rand(1,5e7) - 0.5;
f = fft(data);
plot(abs(f))
