Need help about an SSD comparing..

[Ragnarous]

Why is Intel's 730 ssd write speed so slow (270mb/s) while samsung 850 evo has 520mb/s write speed and is cheaper than Intel's?Here are the links to my local hardware store!

That shop site is displaying different things.

For the Intel:
550 MB/s (Random Read 100% Span 75000 IOPS).
270 MB/s (Random Write 100% Span 7500 IOPS).

For the Samsung:
540 MB/sec Sequential Read .
520 MB/sec Sequential Write.


Go to the manufacturers sites, or other independent tests, for real results.

Sequential is one big block of data.
Random is pieces of random data scattered all over the drive.

Yes, it makes a HUGE difference.

Yes, it makes a HUGE difference.

So, that means intel's is more stable or faster? Or both?

No, it just means that the site is showing you different things.

Go to the manufacturers sites, and go read independent reviews. Both are good drives.
Probably little actual difference between them.
