SanDisk Extreme II 120GB SSD Review - Benchmarks - Sequential Performance

SanDisk Extreme II 120GB SSD Review
We're starting our SanDisk Extreme II review coverage with the 120GB capacity size. Later today we'll publish reviews of the 240GB and 480GB, but the 120GB size has more talking points and shows why SanDisk now has the most advanced NAND on the market today. (NASDAQ:SNDK)

HD Tune is a Hard Disk utility which has the following functions:


Benchmark: measures the performance

Info: shows detailed information

Health: checks the health status by using SMART

Error Scan: scans the surface for errors

Temperature display


HD Tune Pro gives us accurate read, write and access time results and for the last couple of years has gained popularity amongst reviewers. It is now considered a must have application for storage device testing.





This review isn't just going to be about write performance though, the Extreme II can bring it in sequential read performance, too. Here we see a list of top performers and popular SSD's on the market today. The SanDisk Extreme II wrestles the highest average speed away from the Phison controlled MyDigitalSSD BP4, another drive with new 16K page size Toggle NAND.




On this chart the SanDisk Extreme II turns in a 322MB/s sequential write performance result. This test uses compressible data so the LSI SandForce controlled drives get to use their compression technology. We'll look at incompressible sequential results later in this review with CrystalDiskMark.



HD Tach - Sequential Write Performance after Random Writes




Here we see the sequential read and write results after a few random read and write tests. The write performance only drops below 200MB/s on a few occasions.
