Intel SSD: 24k IOPS vs 41k IOPS

[sereneman]

Hey guys!

As i'm building my pc, i have another question, this time regarding an SSD.

Considering the reported lowest return rate and the very long warranty (5years), i've picked the Intel 530 series for my SSD of choice.
I will always put reliability before speed.

I have two questions, though:

530 Series 120GB - 24,000 IOPS read / 80,000 IOPS write
530 Series 180GB - 41,000 IOPS read / 80,000 IOPS write

Note that the difference in storage means nothing to me. I don't even need 120GB as i'm not a file hoarder, let alone 180GB.

What i'm interested in is the difference between that random 4KB Read speed, 24k vs 41k. How will that impact daily operations, such as browsing, copying, extracting archives and gaming? I found nothing specific on google.

Is it worth buying the 180GB version just for the IOPS difference?

Question two: What kind of sata3 cable do i need for the ssd (i'm buying the generic pack, it's cheaper). 2x male or 2x female?

Thanks!

How will it impact it? A rather small amount, not massive, but noticeable.

The reason being is that IOPS are a measure of the number of Input Output Operations a Second.
The higher the number the faster the rate at which the SSD can find and pull/push the data from/to the disk, as you can see, the IOPS for read is double so the read of random files will be double on the 180gb.
Unfortunately, not all data is random, and some is sequential (though I believe most is random).
The read IOPS are to most people more important than the write as we spend more of our time looking at data already on the disk rather than data we want to add.
For your said processes:

Browsing - Probably no difference, very small read and writes, not noticeable.
Copying - Start times might be slightly quicker with the 180gb, but again, this data is sequential and just going from one location to another so probably not much in it once it gets going as the write's are the same.
Extracting archives - Similar performance
Gaming - Faster load times with the 180gb. Here it will probably most noticeable as games save data in so many different places, to go and collect the data from all the different places will need a high IOPS to be done quickly. Lots of randomly stored data.

Of course, both SSD's, being SSD's will be very fast as is. They're performance will be similar, but the 180gb will no doubt be faster.

Is it worth it? Million dollar question, do you feel it's worth it? How much more do you want that bit of extra speed or the extra space for peace of mind.

Q2: Be on the safe side get a sata 3 6Gb/s male to male (safe side being get the fastest there is).
There's not really much price difference between them anyway so go for those.

Well, since it only makes a difference in game load times, it's not worth it. Considering the fact that i'm upgrading to my first SSD from a 7 year old hitachi 160GB HDD, the 120GB SSD will make an immense difference anyway.

Thank you for the thorough answer!!!

I'm honestly amazed every time i ask a question on this forum. You people are so helpful!

Most welcome.
Yeah, it will make an immense difference.
