Hi there!
I was hoping someone here could help me crunch some numbers. I have two SSDs of equal capacity (240GB). One is the Kingston SSD now V300, and the other one is the Sandisk Ultra II. I have two computers and I want to use the fastest of the two in my everyday use computer, and the other one in my second computer (both computers have a SATAIII port).
So I searched around, read lots of reviews and opinions and I ended up downloading a benchmarking software (AS SSD). I tested both drives and got some results. Now apparently, all numbers are not as important. I read that e.g. sequential read/write is important for moving big files, which I won't do, but I should pay more attention to 4K numbers and access time. And If I only look at these, I don't have a clear winner.
Here are the numbers I got:
(Kingston vs Sandisk):
Seq read: 392.74 MB/s VS 464.12 MB/s
Seq write: 176.37 MB/s VS 453.59 MB/s
4K read: 14.71 MB/s VS 21.41 MB/s
4K write: 61.16 MB/s VS 46.72 MB/s
4K -64Thrd read: 91.55 MB/s VS 314.67 MB/s
4K -64Thrd write: 157.47 MB/s VS 268.74 MB/s
Acc. time read: 0.187 ms VS 0.086 ms
Acc. time write: 0.305 ms VS 0.084 ms
I know whichever I use there will be a huge difference compared to my current 5400 rpm HDDs, but if one is better, I'd rather use it where it will gets more used.
4K write is seemingly the only significant advantage for Kingston, so how important is that number compared to the others, and is this benchmark even remotely an indication of how the drives will perform in real life?
Thanks a lot for enlightening me!
