Corsair P64 Performance Series 64GB SSD (CMFSSD-64GBG2D)
Aug 9th, 2009 | By SimonSisoft Sandra – File System
Another common benchmarking program, we have SiSoft Sandra File System Benchmark. The File System Benchmark gives us a quick glance at the overall performance and whether we have a new or full drive, the performance is both consistent and comparable to the 64GB Indilinx drives and 128GB second generation Samsung based drives.
Corsair stays with the class in our File System benchmark. This time we see little difference between a 128GB drive and a 64GB Samsung controlled drive. The one slip I kept seeing was the slow random write speed when the drive is full. The P64 is only performing at 25% the original rate as the newly installed drive.
SiSoft Sandra – Physical Disk
The Physical Disk Benchmark benchmarks the hard disks and not the file system, meaning the graph below compares the performance of the physical disk to the storage adapter, unlike the SiSoft Sandra File System benchmarks which shows performance between the file system itself and the adapter.
The Corsair P64 takes the cake in the Physical Disk benchmark. The random access time is the quickest we’ve seen in a while and the index speed is right at the top with only a 7% difference between a new and full drive.
HD Tune
HD Tune is another hard disk utility to determine the performance of your drive. HD Tune runs a few tests to provide a transfer rate (minimum, maximum and average). It also trends the performance through the entire disk and gives you the access time, burst rate and CPU usage.
New Drive
Full Drive
HD Tune lets us clearly see the performance drop between a new empty drive and one that is completely full. The empty P64 gets to spend about half its time up in the 200MB/s barrier where the full drive stays relatively flat at 170MB/s. The burst speed, random access time and CPU usage is not affected by the free space of the drive, this is a very welcome change compared to the Indilinx drives I’ve worked with in the past; it’s often a 20 point increase in percentage when the drive is full.
HD Tach
HD Tach is a low level hardware benchmark for random access read and writes. The performance numbers are quite similar to HD Tune.
New Drive
Full Drive
Basically the same HD Tune story but imposed onto the HD Tach graph. There is roughly a 20MB/s drop between the new and full drive.
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??
