WinBench 99

We have extended our WinBench 99 portion of our benchmarks to include not only the Disk Transfer Rate tests, but also a couple of other disk performance related tests including Disk Access Time and CPU Utilization. As we present our results, we will explain how each test is relevant in our methodology.

Disk Transfer Rate

In the past, we have just given the beginning and ending transfer rates, which doesn’t really show the performance of the entire disk because there is so much more in between that we are not reporting. Our new method includes a graph:

The WinBench 99 transfer rate test reports results that are extremely sporadic. Starting at a rate of 28.1 MB/sec, the ExBoot drive produces transfer rates anywhere between 26-31MB/sec. Later, we’ll see that HDTach produces similar results.

Disk Access Time

WinBench 99 also has a Disk Access Time test that gives us the summation of the latency, seek time, as well as any overhead involved in seeking data across the disk.

WinBench 99 - Disk Access Time

The 13.9ms access time is quicker than Seagate’s 15ms access time for the 120GB version of their external drive. The ExBoot uses the Western Digital WD800BB drive with 2MB of cache and a 7200RPM rotational speed. The WD800BB is designed with triple 27GB platters, so it’s a wonder why the access times were lower than the Seagate drive.

Disk CPU Utilization

The disk CPU utilization test measures the CPU usage while the hard drive transfers data at a rate of 4KB/sec. While transferring data, our test bed utilizes about 77% of the CPU time on average.

WinBench 99 - Disk CPU Utilization

This figure looks to be around the ballpark of CPU consumption for USB based drives.

    I was able to backup my notebook's SATA hard disk without any problem but when it comes to restoration, it is a different ball game. As my notebook does not support boot up from USB, I used the Recovery CD from exboot to boot up. Unfortunately, the restoration cannot be done because the recovery software does not detect the hard disk in my notebook. Is it because the software cannot support SATA hard disk?

    External USB/Firewire drives are commonplace these days. I can choose from a dozen manufacturers based on price, quality of construction (I prefer metal-cased drives and rubber antishock mounts for the HDD itself), etc., or I can even buy an enclosure and choose my own drive, which I've already done, since a USB 2.0/Firewire case was about $40 on sale a year ago, which lets me choose the performance I want by choosing a hard disk to fit my needs

    What makes or breaks a pre-made drive then, is the software and features like the pushbutton backup, which the company didn't even bother to include software support for (or so it sounds like from the wording of the review). Does the backup software offer data compression so I could perhaps fit 100-140GB of data on that 80GB drive? Didn't sound like it, but it wasn't made clear. How well did the backup software work? You didn't tell me how a backup/restore of a boot drive worked. And of course, it was mentioned that the user couldn't choose which files to back up. The ExBoot says on the side of the case "Backup and Instant Recovery". For any drive that bears that logo, a review ought to exhaustively test that claim.

    I agree this is a less-than-average product. Most uber-geeks don't buy an external HDD for ultimate performance; for that, we'd get an internal SATA or PATA drive. Performance testing is good up to a point, but most enthusiasts buy an external disk for transfer between multiple computers, or for backup. If ExBoot wants to sell me a drive, I want all the features working, and your top quality software, no matter which capacity drive I choose. Otherwise I can buy a five-year warranty Seagate IDE disk (note: very few external HDD manufacturers offer more than a 1-year warranty) and put it in an enclosure of my choosing, and then purchase Symantec Ghost or even use Windows Backup for free.

    Does this thing boot to windows externally? I don't think win xp can boot from an external hdd. When XP initially loads, all the USB devices reset. Therefore I don't think you can boot to windows with this?

    The system will actually boot off this USB device if a successful backup is made with the software. It is also one of the main features of the drive.

    This would be good for someone booting from a 74GB Raptor drive. As mentioned, the spartan software is not a problem if backing up an entire volume.
  • ElFenix - Thursday, November 10, 2005 - link

    i doubt you'd find many volumes to back up that were larger than that.

    I have a 120Gb external that I use for backups of DVD images and the like, and that is too small. 80Gb? wow
