Kingston HyperX 3K (240GB) SSD Review
by Anand Lal Shimpi on April 10, 2012 3:00 AM ESTAnandTech Storage Bench 2011 - Light Workload
Our new light workload actually has more write operations than read operations. The split is as follows: 372,630 reads and 459,709 writes. The relatively close read/write ratio does better mimic a typical light workload (although even lighter workloads would be far more read centric).
The I/O breakdown is similar to the heavy workload at small IOs, however you'll notice that there are far fewer large IO transfers:

Just out of interest, when you talk about filling the drive and then 'TRIMing the drive', how exactly do you do this? I thought TRIM was automatic (in the right OS), or is there some command that can be run to 'TRIM' a drive?Coup27 - Tuesday, April 10, 2012 - link
In Windows 6, TRIM is triggered when a file is actually deleted, so a format, empty the recycle bin or shift+del a file. When AT test SSDs they are connected as a storage drive, so it is easy to torture the drive and then TRIM it by formatting it within disk management.Coup27 - Tuesday, April 10, 2012 - link
^ Windows 7.Aside from that, Intel and Samsung have toolbox programs which allow you to manually force a TRIM and GC pass.

Thanks Coup!hrrmph - Tuesday, April 10, 2012 - link
BIG THANKS for including the information that it has a toolbox and that the toolbox doesn't support secure erase!hechacker1 - Tuesday, April 10, 2012 - link
What's Kingston's warranty on this? That lets me know about what they expect in terms of support.itsmepj - Monday, May 28, 2012 - link
fast is fast.. but not reliable..... i bough mine in Jan 2012... last week sent back for warranty, cannot detect..... all data gone.... yet replacement unit have to wait for 4-8 weeks time from Taiwan.... very bad backup service..... sadkillabee_me - Saturday, June 2, 2012 - link
I would love to see Anandtech review Sandisk Extreme SSD 240GB .The word is that Sandisk managed to fix one of the biggest problems with Sandforce - the TRIM actually works 100% and the performance is back to the advertized one even after hours of torture tests with incompressible data.
In addition the Extreme series use a very fast SanDisk's own 24nm Toggle Mode NAND and a custom optimized firmware, which results in one of the fastest SSD on the market. The price is extremely competitive as well.
It would be interesting to see what it can do in AnandTech Storage Bench.

Anand,Why have you assumed a write amplification of 10x ?
Looking at xtremesystems dot org forums for SSD-Write-Endurance-25nm-Vs-34nm, it appears that 1x seems more common (with only the Samsung 470 showing 5x).
Are these stress tests unrealistic and therefor somehow lowering write amplification?
Could you please provide some insight as to how you came up with this figure.
I thought that most SF and Micron based drives had write amp neer 1.0

In the end, I buy the HyperX or HyperX 3K?
