Samsung SDD Difference

[Gnexus]

I'm thinking about getting a Samsung SSD, and I wanted to wait till Black Friday to do it. I was also thinking of setting up the SSD in a Raid 0 format. According the local Computer shop the Samsung Evo has a 4k random read speed of 97,000 IOPS and write speed of 66,000 IOPS.

 

The Samsung pro is listed as 100K IOPS for read, and 90K IOPS write speed. 3.1% difference in read, and 36% difference in write speed.

 

I'm typically pretty good at staying on top of anything new that comes out, but I've never heard of the phrase IOPS before. Could anyone explain what it is, and why the 4k read and write times are important ?

I believe it means <something> Operation per second?

 

Maybe Internal Operations Per Second. Iunno

IOPS stands for input/output operations per second and is used to benchmark storage devices.

 

4k (file size) write writes scattered data on the drive 

 

SSDs in general are more or less saturating sata 6gb/s to its fullest, so you'd be hard pressed to perceive any speed difference.

I would avoid samsung drives (atleast EVOs) for the time being. There is a read bug, that causes slow reads and has yet to be fixed (firmware is on the way tho).

Well there isn't a big difference in the price from the two, so I will look into getting the pro. Can you set up the drives for Raid 0 and then make a mirror image of my Windows drive, and copy it over to the Raid 0 drives ?
