Posted: September 8, 2000 Written by: Dan "Tweak Monkey" Kennedy Benchmark: SiSoft Sandra Since SCSI drives are so versatile (they can be put to many uses and raw speed isn't really the best way to test them), these benchmarks only hold so much bearing on its performance. Anyway, here we go... SiSoft Sandra Disk Benchmark  The performance here is quite impressive, especially since I tested two 7200 RPM Maxtor DiamondMax ATA66 drives and both scored just under 10000 on this test. Another interesting point is that this drive scored 29500 earlier when I ran the benchmark. I'm not sure why the performance varied so much, so I decided to use other tests as well.  This is the Atlas 10K (not the 10K II); an earlier model of the same drive. It supports most of the same features as the Atlas 10K II, but alas, it's much slower. The technical information at the bottom (specific #s on performance) are as follows: Atlas 10K II: Test File Size: 192 MB Current Disk Cache: 68 MB Maximum Disk Cache: 120 MB Minimum Disk Cache: 5 MB Typical Role: Network Server Benchmark Breakdown: Buffered Read: 112 MB/s Sequential Read: 36 MB/s Random Read: 11 MB/s Buffered Write: 89 MB/s Sequential Write: 19 MB/s Random Write: 13 MB/s Average Access Time: 4 ms Atlas 10K: Test File Size: 192 MB Current Disk Cache: 60 MB Maximum Disk Cache: 120 MB Minimum Disk Cache: 5 MB Typical Role: Network Server Benchmark Breakdown: Buffered Read: 143 MB/s Sequential Read: 20 MB/s Random Read: 7 MB/s Buffered Write: 9 MB/s Sequential Write: 14 MB/s Random Write: 7 MB/s Average Access Time: 6 ms (estimated) As you can see, the Atlas 10K II really rocked the Atlas 10K, even though it is still one of the fastest SCSI drives on the market. Benchmark: HD Tach HD Tach is another benchmark that I decided to give a shot. It seemed to be pretty accurate with my IDE drives so I thought it would be accurate with these SCSI drives. Here's how they performed:  Atlas 10K II; Click to enlarge  Atlas 10K; Click to enlarge While the performance appears to be more consistent with the Atlas 10K, the Atlas 10K II is definitely faster. And now, onto the last page... some more benchmarks, and a conclusion... |
