One of the finest tools available to measure storage performance is ATTO. I love it to death as it is so reliable and produces such accurate results. The great thing about ATTO is that we can test with predefined block sizes. So we can test with a 32MB sequence of 4KB files, yet also 32MB in 1MB files. This gives us an excellent scope of overall performance with small and large files.
ATTO Write performance
The most important and difficult task for any storage unit is ... writing really small files fast, so let's start off there and have look at that with this WRITE test. We scale 4KB block sizes to 1024KB block sizes in bursts of 256MB with a queue depth of 4 and then measure how fast the storage device is dealing with them. The storage units we used:
OCZ Vertex 120GB (MLC) Indilinx Barefoot
OCZ Vertex 2 100GB (MLC) SandForce SF1200
G.Skill Phoenix 100GB (MLC) SandForce SF1200
G.Skill Phoenix 120GB (MLC) SandForce SF1200
We recently added the latest revision of the Western Digital WD1500HLFS VelociRaptor to our test suite, it is considered amongst the fastest and most expensive 10k RPM HDD your money can get you. It's read/write performance is unprecedented good for a traditional/mechanical HDD of course.
Then the original OCZ Vertex, then the OCZ Vertex 2 in yellow (fall under the phoenix lines) and finally in red, the MLC based Phoenix nearing ~250MB/sec write performance.
Look at the 4KB file size test by the way and compare it to the Indilinx product in green, that is astonishingly good. That's the strength of the SandForce controllers.
ATTO Read performance
The previous test was write performance, but let's have a peek at read performance. The SandForce-1200 controller based SSDs kicks ass and definitely take a lead in this particular benchmark.
The SSDs are all really fast, but that's 282 MB/sec read performance when it's peaking. And again look at the tremendous increase in small file operation performance. Again that's more than double of Indilinx based products up-to 64KB in this particular test.
G.Skill Sniper 8GB CL7 DDR3 memory review G.Skill designed another 8GB low voltage DDR3 kit (2x 4GB) that can be set at 1600 MHz yet still run a CAS latency of 7. And that is truly interesting because the denser the ICs get, the higher latency typically gets.
G.Skill 2x4GB CL7 1600 MHz Trident DDR3 review We feel that more memory is rather important, and in that trend memory manufacturers have started to increase the density of DIMM modules. Where 1 and 2GB DIMM modules have been the standard, we now see very good progress in 4 GB DIMM modules. Today we\'ll do things a little different, G.Skill designed a 8GB low voltage DDR3 kit (2x 4GB) that can be set at 1600 MHz yet still run a CAS latency of 7. And that is truly interesting because the denser the ICs get, the higher latency typically gets.
G.Skill Flare DDR3 2000 MHZ C7 AMD kit review We test and review the G.Skill Flare DDR3 2000 MHZ C7 AMD kit. These kits are optimized for AMD platforms preferably with the new six-core X6 processors, and in specific some ASUS motherboards. The kit we'll be testing today obviously comes from that series and is a 2,000MHz CL7-9-7-24 1.65V 4GB (2GBx2) DDR3 kit with its latest Flare heatsinks.
G.Skill Phoenix PRO 120GB SSD review The SSD tested today once again is the Phoenix series from G.Skill. After we tested their 100GB Phoenix SSD (which received a very positive review) G.Skill instantly requested if we would like to review the 120GB PRO model. Both drives pretty much are the same thing, same controller ... The 100GB Phoenix uses Samsung memory though but the trick is that there is 20GB extra volume space available on the new 120GB Pro (compared to the 100GB model) for nearly the same price. A new Firmware for the SandForce 1200 based controller that is inside this 120GB model simply reserves less NAND flash memory for its data-compression scheme. As a result the overall write performance could be a tiny bit slower, but only a few percent as best. It however will give you 20 GB more space to play around with at the same price. And since price per GB is everything in the land of SSDs -- this certainly is a significant for any vendor and for you as an end-user.
