My thoughts on software and technology

Interesting readings for the weekend.


In case you are looking what to reading during the weekend I found a couple of articles. I like hardware stuff so all of them are mostly that. The guys at www.bit-tech.net have some very good hits.

 

CPU related.

Intel 45nm technology overview High-k, Metal Gate Transistors and Penryns.

Intel talks about Nehalem, Larrabee & 32nm Event more acronyms - Nehalem, Tukwila, Larrabee, Sandy Bridge.

My guess is that we will remember one for a long time - Nehalem (just like web now know Conroe).

 

Memory.

Read the very detailed articles on PC Memory. What DDR is? DDR1 vs DDR2 vs DDR3 vs Graphics DDR (GDDR) vs QDR and XDR. What is a Data Eye? DDR Topology, memory hierarchy, latency and bandwidth and more.

The Secrets of PC Memory: Part 1

The Secrets of PC Memory: Part 2

The Secrets of PC Memory: Part 3

The Secrets of PC Memory: Part 4

 

HDD stuff.

Understanding RAID

In the last few years RAID has become really quite popular. Once purely in the domain of high-end enterprise servers, today, any self respecting enthusiast motherboard had better have onboard RAID if it wants to be taken seriously. The abundance of onboard RAID controllers mean that it’s not unusual to see small arrays in today’s home computers. The reasons for this can be for increased speed, increased reliability or simply for bragging rights. After all, two (or more) disks are better than one, right?

One thing I can add is "Never do a RAID 5 array on your MB integrated controller (P965 to be specific), NEVER".

 

Introduction to hard drive technology

So then, what do all of these fancy letters mean? NCQ, TCQ, RAID, IDE, SCSI, SATA, MTBF, SCSI vs. SATA, Asynchronous Notifications. Article for HDD basics.

 

Misc

64-bit: More than just the RAM - The 64 million dollar question!

First Look: Extensible Firmware Interface EFI the new Bios is here.
