Hard drive - 18.2 GB - hot-swap - 3.5" - Ultra2 Wide SCSI - 80 pin Centronics (SCA-2) - 10000 rpm

Advantages: Smaller, less power hungry
Disadvantages: None

...Following on from my review yesterday on server Ultra SCSI hard disks, here im going to tell you about their younger, smaller and better brother. The Serial SCSI hot swap 146.8Gb Hard disks by HP. As with all technology, everything seems to be in the constant evolution to downsize. Hard drive downsizing always struck me as a difficult one to tackle as people require more and more storage, hence bigger disk space. Somehow the Serial SCSI has mastered this by shrinking the form factor down from a width of 3.5 inches to 2.5. The Height of the device is also somewhat reduced. A reduction in size means a reduction in moving parts size. This in turn leads to a great power saving which makes these drives more economical and environmentally friendly than their older but bigger brothers. As mentioned we have a mixture of G4 and G5...

Advantages: Great reliability. Good storage. Quick to install
Disadvantages: Power hungry

...When you need large disk capacity, bulletproof performance and reliability in your servers, you cant really go wrong with the Hewlett Packard Ultra320 146.bGb Scsi hard drives. When you are running RAID5 on a server and need lots of disks to add to the array, these meaty old disk are a surefire winner every time. Whats more they are in the standard 3.5 inch size and can fit in almost all server applications that require Ultra320 disks. We have a mixture of G4 and G5 Hewlett packard servers here at work and these drives suit the G4 style servers. The have an easy access and hot swap caddy to contain them which makes swapping the drives much easier should you need to as well as the initial install. Installation. You cannot get simpler. Open the box. Slide the Hard drive into the allocated bay in your server until you feel... Read review

...to hold five Ultra3 hard drives, a 133MHz bus and Intel's newest processors which run on a ServerWorks Entry ServerSet III LE chipset. It achieved satisfactory results in our benchmark tests. More drives should mean better performance. However, the PowerEdge's had a middling performance on our file server benchtest, a more hard-drive-dependent metric that measures a server's throughput in file read and write requests from clients. The server’s total throughput was 1.31 MB per second. Our web server benchmark test rated better with throughput at 1.78 MB per second. The server managed 122.5 transactions per second in the file server test and 118.8 transactions per second in the web server test. The PowerEdge 2450's slender chassis can support 90GB of total storage with five 18GB drives running at 10,000rpm. An integrated Adaptec AIC-7899... Read review
