We Have a Winner - Seagate
Краткое содержание статьи: Finally, we received one of Seagate's 15,000 rpm monster hard drives. Get ready for one of the most interesting high-performance SCSI drives available, and see how it compares to typical 10,000 rpm models.

Get Ready for Seagate's High-performance Drive

Logo

It took a while before Seagate provided us with the Cheetah X15, one of their fanciest hard drives. The Cheetah series of drives has been groundbreaking in its own right - several years ago, the first model in the series was also the first to break the 10,000 rpm barrier. Increasing the rotation speed is one of the most popular ways of improving hard drive performance. Today, every SCSI hard drive manufacturer ships at least one family of drives that runs at 10,000 rpm, which has become the current standard for high performance SCSI drives. In the IDE sector, 7200 rpm is the current standard, but perhaps it also won't be long until we see the first 10,000 rpm IDE drives.

15,000 rpm Drives: A Balancing Act in Design

There are basically two ways to increase the performance of hard drives: increase the rotation speed or increase the data density. Increasing the rotation speed definitely enables better sequential performance, but only if you adjust the read/write mechanism accordingly. Increasing data density is also a popular method - recently, Western Digital announced the first drive with 27 GB per platter, which is in strong contrast to the 15 or 20 GB per platter for most IDE drives and a greater contrast to the even lower densities for most fast-spinning SCSI drives. However, the catch is that high density doesn't allow top rotation speeds, and vice versa. So essentially, designing a fast hard drive involves creating the most ideal balance between rotation speed and density.

История мейнфреймов: от Harvard Mark I до System z10 EC
Верите вы или нет, но были времена, когда компьютеры занимали целые комнаты. Сегодня вы работаете за небольшим персональным компьютером, но когда-то о таком можно было только мечтать. Предлагаем окунуться в историю и познакомиться с самыми знаковыми мейнфреймами за последние десятилетия.

Пятнадцать процессоров Intel x86, вошедших в историю
Компания Intel выпустила за годы существования немало процессоров x86, начиная с эпохи расцвета ПК, но не все из них оставили незабываемый след в истории. В нашей первой статье цикла мы рассмотрим пятнадцать наиболее любопытных и памятных процессоров Intel, от 8086 до Core 2 Duo.
