SSD's, "rated" preformance & benchmarks question

[imortal]

I've been reading around the net and doing testing for about 6 hours, started off with getting annoyed that my new 550 mb/s rated SSDs were only performing at about 240-350 mbs read/write so after couple benches and more reading realized that I wasn't running on AHCI, So got that taken care of then did about 2 more tests and still only in the 400's. Stopped testing when I started reading mixed reviews that benchmarks on SSDs can kill it, So my question here is, what is the real verdict on that? one of my drives has 400 gbs of bench write data and 50gb read on it, did I severely reduce its life?

If there's a professional storage person out there please feel free to answer me I really need some Pro advice here.

you didnt severely reduce its life with a couple benchmarks

which testing software were you using? which ssd?

 

[noidea_77]

The data written to and read from the device is not relevant for it's lifetime so far. On the other hand, the read/write speed is irrelevant as well, as long as it is so close to the maximum. The most important advantage of a SSD over a HDD is the very short access time, not the read/write speed. You will never notive any difference between the 400 mbs and the theoretical optimized benchmark maximum of 550 mbs. Stop waisting your time.

AS-SSD, ATTO, UserBench and samsungs magic software probably a total of 6 bench's on each drive between the programs

What SATA port is it plugged into? Intel or Marvell? (it makes a difference)
What drive is it?

You've not reduced the lifespan.
Doing that 10 times a day, every day for a year...maybe.

Z68 board, using the SATA 6gbs intel chipset as the port, funny cause the main drive is that one the 840 EVO, it seems to be up to par last bench before i stopped showed 505/502 mbs but im concerned about this Corsair Force GT which it reported around 460 / 250 almost every time, the 250 of which is half of what its rated max is suppose to be. of 520
