Solved How close should benchmark come to advertised speeds? Tags: SSD Benchmark Storage Last response: January 12, 2013 5:12 AM in Storage Share gleipnir January 12, 2013 2:09:39 AM I recently built a new rig with a 120GB intel 520 series SSD. I'm very happy with the drive, but just wanted to get into the nitty gritty and see how it was really performing. CrystalDiskMark consistently reported read speeds of about ~490MB/s and write speeds of ~480MB/s However, the advertised speeds for the drive are 550MB/s read and 500MB/s write. Are these normal/close enough values for me to conclude that my drive is in fact working 100% properly? I already have the newest firmware and drivers.

It's like cars, sure they say 5.1L/100km or whatever, but in real life and when the car isn't brand new off the assembly line, there is going to be small variations. You are within a few MB/s. gleipnir January 12, 2013 2:14:40 AM I guess for write speeds it's fairly close. What was sort of bothering me was the read speeds which are about an entire ~60MB off Related resources New SSD not reaching the advertised speeds - Forum Why do I have to OC to get advertised speed ? - Forum Solid state drive reading at half the advertised speed but writing - Forum SSD below advertised speed - Forum Slow write speeds with Intel 520 series SSD, why? - Forum Can't find your answer ?

You are a bit slower then that but probably ok. Maybe try updating drivers? Best solution manofchalk a c 94 G Storage January 12, 2013 2:46:10 AM Share The advertised speeds were probably made under ideal conditions, using data that the drive can easily handle and hooked up to a system where it is the bottleneck. 500MB's is about as fast as most SSD's will realistically go. gleipnir January 12, 2013 5:12:29 AM Best answer selected by gleipnir.
