Unfortunately, I wasn't able to test the Instant GigaDrive against a network shared SCSI drive or RAID Array. However, the benchmarks against other IDE Drives are very impressive. There was a fair amount of consistency between the results of the two separate benchmark utilities. The unit appears to be much faster than a shared drive of the same drive type when downloading from it. However, uploading to the drive appeared somewhat slower. What really confused me is the fact that the drive seemed to perform much better during tests when other systems where placing large loads upon it. My only theory for explaining this is that multiple loads on the unit prevent it from spinning down. I'm only guessing though.

The first thing I did was to test latency from the systems on my home LAN. In each case the pings received were the best possible times. Unfortunately, I'm going to have to explain this. If you receive a ping time of between .1 and 1ms, the Microsoft ping tool will list the time as <10ms. It makes no sense whatsoever, but that's the way they wrote the tool (It should say =<1.0Ms). If you look at the bottom of the ping test results you will see the Minimum, Maximum and Average ping times are listed as "0ms", which is also an inaccurate representation. To sum up after this mess: The Instant GigaDrive received the best possible results from the Microsoft Ping Tool test.

Aside from the multiple access testing (bottom of the page), I used one system as a 'BASE' for the single connection benchmarks. The system specs are as follows:

  • Abit BE6 (rev1) w/ built in ATA/66 controller
  • Intel PIII 600Mhz
  • 256M of PC100 8ns RAM
  • Win98SE
  • Soundblaster Live
  • Creative TNT2U
  • DLink 10/100 PCI NIC (Set to 100Mb FD)
  • WD 18G ATA/66 HD (7400 RPM, 2M cache)
  • Maxtor 20G ATA/66 HD (7400 RPM, 2M cache)
  • no USB/LPT/Serial Connections active
  • registry tweaked with the current '98' tweak INF from Speedguide.Net for Cable/DSL performance

As you can see, the GigaDrive performed MUCH faster at 'read' tests than similar shared PC drives. However, it was considerably slower at write tests (writes to it). I'm very happy with the results. Networks drives are normally downloaded from much more than they are uploaded to.

Again, the GigaDrive does much faster when files are downloaded from it compared similar shared PC drives. However, it also was once again slower when files were uploaded to it (not by much though).

I have to say I'm somehow confused by the results. The Instant GigaDrive seems to perform better when three systems are using it at the same time. Considering that normal network transfer rates are much slower than even the slowest hard drive, the increased usage may have kept the RPM level up on the drive and provided better performance. I'd have to say that you should take this with a grain of salt. I ran this test three times and received the same results. But, I have no idea if this is an accurate representation, or how to explain why the results appear as they do.

I do like the testing results that I've seen. In my experience downloads from a network drive are much more frequent than uploads, and this unit performed much better at file downloads than similar Hard Drives shared in local PC's.

Let's move on and take a look at how this unit can also be used as a Print Server.
