As we've seen previously, drives a with superior dedicated cache perform best in the burst speed test (as data is being read from the cache, not the drive itself). It's for this reason that the Samsung F1 1TB is able to produce such good result here, with its large 32MB cache working well to record a burst speed of a whopping 234MB/s.

Speed (MB/s
Average read speed across the drive isn't too different from the both the Seagate 1TB and 250GB hard drives, with the Samsung able to poke its nose ahead by just a few MB/s. It's certainly no match for the zippy SSDs we've tested, but then we never expected it to be - this is still a mechanical drive when it comes down to it after all

Disappointingly random access times were a little slower than the Seagate 1TB, and were a long way off the 8.9ms response time quoted by Samsung. While still nippier than a basic 250GB drive, we were expecting a little more.
