Benchmarks Real world tests of Ultra Plus SSD vs Extreme SSD

4K Random Read

Ultra Plus SSD
127.4 MB/s
Extreme SSD
123.46 MB/s
Ultra Plus SSD Extreme SSD @ ssdreview.com
Benchmark Results: IOPS are a good bit below the SanDisk specification of 82k on reads and a little above the 39k specification on writes but overall decent performance.

4K Random Write

49.81 MB/s

Ultra Plus SSD Extreme SSD @ ssdreview.com
IOPS really doesn't vary as dramatically with reads ranging from 79k to 82k and writes from 29k to 39k.

Windows 7 Boot-up Time

Ultra Plus SSD Extreme SSD @ ssdreview.com
It does a nice job of moving data quickly without the need for compression to boost performance; however, it does rely on a cache to buffer data as needed which sets it apart from the SandForce drives.

It would be interesting to put all three capacities on the test bench and see how the real world usage pans out.

4K Random Read Access Time

Ultra Plus SSD
5.02 ms

The Ultra Plus, however, impresses in the 4K random read/write results and posts the fastest read speeds we've seen and is pushing on for 60MB/s on the writes.

4K Random Write Access Time

Ultra Plus SSD
1.96 ms

For such a quick drive, which is incredibly responsive on the desktop, to be on the market at 51p per GB is fantastic - and if you can't afford to push the boat out for either the OCZ Vertex 4 or Vector drives then the SanDisk Ultra Plus will not disappoint.
