SSD Performance Atto Disk Benchmark

Atto Disk Benchmark
One of the finest tools available to measure storage performance is ATTO. I love it to death as it is so reliable and reproduces such accurate results. The great thing about ATTO is that we can test with predefined block sizes. So we can test with a 32 MB sequence of 4KB files, yet also 32 MB in 1MB files. This gives us an excellent scope of overall performance with small and large files.
ATTO Write performance:
The most important task for the SSD is ... writing files. We scale 4KB block sizes towards large 1024KB block sizes in bursts of 32MB and then measure how fast the storage device is dealing with them. The storage units we used:
- Samsung SP0802N ATA (80 GB)
- Maxtor 6 Y200M0 (200GB)]
- WD15 00ADFD0 Raptor (150GB)
- OCZ CORE SSD (64GB)
- Silicon Power SSD SLC (32GB)
- G.Skill SSD (64 GB)
As you can see all SSD drives stumble into their Achilles heel with small file block sizes. For any SSD, small block files are much harder to write fast. But still that's really performance that can be compared to an average 5400 RPM HD.
Once we pass 16KB file sizes ... the Silicon Power SSD starts to rock. Current word is that, for Windows Vista, a patch is in the works to prevent small block-sizes, which would help greatly. For an MLC SSD the write performance is good above the 16K block size, below that it could be better.
We see that the G.Skill drive indeed surpasses the 90 MB/sec write performance and in some instances even touched 100 MB/sec of write performance.
ATTO Read performance:
Once we look at read performance of the tested unit we are a little flabbergasted. Again we see the drive surpass the advertised 155Mb/sec performance threshold and we measure over 165 MB/sec at several points.
Follow the bright green line, we see the SSD to be slower at really small block sizes. But here as well, after 16KB file-sizes .... the performance goes into the stratosphere.
That read performance is twice as fast compared to a 150 GB WD Raptor drive. Mind you that the G.Skill drive is one of the cheaper MLC drives available. Roughly 160 USD. As Paris Hilton likes to say: "That's hot".
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.
