Corsair P64 Performance Series 64GB SSD (CMFSSD-64GBG2D)
Aug 9th, 2009 | By SimonATTO Disk Benchmark
ATTO Disk Benchmark is probably one of the gold standards when it comes to basic drive performance. The software itself is fairly old but it works, measuring transfer rates at different transfer sizes for a file being 256MB in size.
Our first reading benchmark shows negligible read transfer rate differences between second generation Samsung based SSDs and Barefoot controller based drives. The Corsair P64 easily smashes through the 200MB/s wall and stays up with its bigger brother the 128GB second generation Samsung SSD branded by Super Talent.
When it comes to file writing, the Corsair P64 starts off on par with the 128GB Super Talent MasterDrive SX but loses steam as the block sizes increase. However, comparing the P64 to the same size Patriot Memory 64GB Torqx based off the new Indilinx Barefoot Controller, the two drives have very similar performance.
Crystal Disk Mark
Crystal Disk Mark is another disk benchmark software commonly used and unlike ATTO Disk Benchmark, Crystal Disk Mark is our first look at sequential transfer rates as well as 4KB and 512KB Random transfer rates.
Crystal Disk Mark paints a very similar picture. The differences in read transfer rates between the P64 and the competition are very small. We also see no difference between the empty drive and full.
When it comes to writing, the Corsair P64 goes toe-to-toe with its same sized 64GB Indilinx cousin with 4KB random writing. The P64 is a few MB/s slower with the 512KB random writing but has a significant lead with sequential writing. The 128GB SSD has the upper hand in all our benchmarks but that’s generally expected with SSDs – the bigger the drive, the better the performance. I bet if we had the P128 on hand, Corsair and Super Talent would be dancing on a very thin line of difference.

There’s nothing fancy to DiskBench – I commonly use it to see how long it takes to copy a file from one source to another. Seeing as this is a hard drive review, I’m going to use the “Create File” feature and determine the speed at which the hard drive is able to create a 200MB file consisting of 100 2MB blocks.
The Corsair P64 puts up numbers closing resembling the mechanical Seagate drive and the SSDs, with the exception of the G.Skill JMicron.
I’m buying just this Corsair 64GB model. I hope that makes all the difference, because an investment is high for such a low capacity. The gap needs to actually exist in the speed of all applications on the disk.
Had the option of another series SSD Corsair, but as this has 128MB Cache ended up choosing this model. Others have only 64MB Cache, however, have read up to 270mb / s and recording of up to 130MB / S while the P64 model offers up to 220MB of read / write S and up to 120MB / S.
I hope I have made the right choice at the time to prioritize the most CACHE 128MB, not just the reading speed.
I intend to use it on my ThinkPad Lenovo Y430 Laptop (T9300 C2D 2.50ghz / 6mb L2 / FSB 800 – 4 GB DDR2 800 Memory) so far with a 250GB SATA 5400RPM HD.
I made a good investment in the choice of SSD HD CORSAIR P64??
