Benchmarks
ATTO Disk Benchmark v2.46
The ATTO benchmark is a widely-accepted Disk Benchmark freeware utility to help measure storage system performance. It performs read/write tests on the storage system and provides numerical data about the performance of the drive indicated by it’s read speeds and write speeds measured in megabyte per seconds (MB/s). Overall the 750GB drive performed very well with sustained read/write speeds ranging between 100 and 120 MB/s. This drive is very quick!

CrystalDiskMark x64 v3.0.1
Another widely adopted tool to measure drive performance is CrystalDiskMark. These tests provide valuable information about the drive such as the sequential reads/writes speed & random 512KB, 4KB, 4KB (Queue Depth=32) reads/writes speed. The sequential read/write is basically reading or writing data records one record after the other making for the quickest method of record read/write. The random read/write 512KB, 4KB, 4KB QD32 tests read or write data records in random order, slower and tends to be common when multi-tasking on a computer. CrystalDiskMark was run 5 times for each 50, 100, 500, and 1000 MB test file sizes. The read performance ranges between 102.7 and 116.6 MB/s sequential which again is excellent for a drive of this capacity and in a laptop 2.5″ form factor.

HD Tune v4.60
This utility is a great way to subject a drive to a range of read/write tests and see the results in a detailed graph showing the speed and time performance of the drive throughout the course of the test run. HD Tune will also perform a variety of functions including the “ability to measure the drive’s performance, scan for errors, check the health status (S.M.A.R.T.), securely erase all data and much more.” First off for those interested in the advanced specification of the Seagate Momentus 750GB here is what HD Tune Reports:
HD Tune Info about drive
Next up a full read test showing minimum, maximum, and average transfer rates; access time; burst rate; and CPU usage:
Transfer Rates
Minimum: 59.5 MB/s Maximum: 112.9MB/s Average: 88.8 MB/s
Access time: 15.2 ms
Burst rate: 145.9 MB/s
CPU usage: 4.6%
The Seagate Momentus 750GB is fast with an excellent maximum and burst rate. The average transfer rate is fantastic with an approximate 27% increase over the 640GB version reviewed earlier. The access time is a little higher, but this is because of the high capacity of the drive.
Below are some additional tests done with 32KB, 1MB, and 64MB. This drive performs consistently well, especially capable as file size increases.

All new drives,whether SSD,SSH or HDD should be SATA III 6gb/s,with backward compatibility for SATA II ans SATA 1.
The switch needs to be made,NOW!
Rotational media and most released SSD’s barely max out the bandwidth of SATA-IO spec SATA II, releasing all drives with SATA III as standard would increase costs so the switch is not totally necessary right now.
If the device is capable of SATA III speeds and exceeds SATA II speeds then yes it should definitely be SATA III
