Why DDR SSDs are the next step

In the last 25 years CPU speeds have increased by 1000x, hard disk capacities have increased by 1000x, memory speeds have effectively increased by 500x, mobo bus data transfer speeds have increased by 500x and floppy disks have been replaced by flash disks, which are 100,000x larger and 1000x faster than a 1.44MB floppy. But hard disk access times and sustained transfer rates and IOPS have only increased by around 5x. So hard disk performance is the last bottleneck in the modern PC. In fact the modern PC has become a ludicrously overspecified mechanical hard disk controller. Every component within it cycles at speeds faster than 200 MHz except the hard disk which cycles at 120 Hz (7200 rpm) or 166 Hz (10,000 rpm) or 250 Hz (15,000 rpm).

There is presently only one way to fix this bottleneck. A Solid State DDR drive. Please do not confuse flash SSDs with DDR SSDs. They are entirely different devices. Sure they are both solid state, but then so is a lump of concrete.

You will not double the real world performance of your PC by buying a faster processor, or a faster graphics card or a new motherboard. In many circumstances a large RAID system of the fastest hard disks will double overall system performance. But to achieve an order of magnitude improvement in real world performance you have to tackle the bottleneck of mechanical hard disk latency, or indeed flash drive write latency, which is not much better.

The most effective way of doing this is with a HyperDrive5, which is truly the world's fastest internal SSD. There are flash drives with faster Sustained Transfer rates, their write latency is diabolical and flash drives do not perform to their quoted figures in the real world.

Intel and AMD and the memory companies and the PC magazines which earn advertising revenue from these companies will tell you that you should get a faster processor or a faster Memory stick or a faster Graphics card. But a typical Front Side Bus today goes at 800MHz with a 64bit memory word, which makes a 6400MB per second transfer rate (PC6400). Whereas your Hard Disk has a theoretical Max Transfer rate of around 80 MB per second (if it is a WD Raptor). And in the real world due to seek time delays it will actually be operating at between 10MB and 40MB per second. So your CPU is speaking to your memory at precisely 6400 MB per second because DDR is a Random Access and has a seek time measured in nanoseconds, whereas your Hard Disk is talking to your CPU at 10MB-40MB per second. So your HDD talks to your PC around 200x more slowly than your memory does.

That is the fundamental incompatibility in the modern PC.

Increasing the 6400MB per second figure is not going to help, when the bottleneck is the 10-40MB per second figure. The HyperDrive5 lifts that figure to around 160MB per second all the time, since it has an STR of 175MB/s Read and 145NB/s Write and as no seek time latency to speak of, being a random access device with a 10 microsecond access time. So adding a HyperDrive5 to your system will lift your HDD performance by 400%-1600% depending upon your circumstances. Buying a faster Processor or Memory stick will give you perhaps a 10%-20% real world performance improvement. The Hard drive is to a PC what speakers are to a HiFi. Running a Quad Core CPU from a Hard Disk is like running a Pink Floyd Stage Amplifier through a railway platform speaker!

For performance you must start with the Hard Drive.

The types of users who need DDR SSD performance are...

* Any real time business transaction system (business time is money)
* Any system where highly trained professional people sit in front of screens for hours (professional time is money).
* Any serious PC gamer
* Anyone who uses a PC more than one hour a week, whose time is worth more than £50 an hour
* Any system with a large database, any SQL performance database system
* Any network with more than 2 concurrent users, any heavily used webserver

Here are the SQL database performance figures from a large US customer who compared one HyperDrive4 with an Areca RAID controller against 14 SATA Hard disks.

The simplest and cheapest way to get mainframe performance from your PC.

A $499 notebook with an external SATA HyperDrive5 will be over 3x faster than a $2000 desktop at booting and clicking around the desktop and opening applications and all other IO intensive operations. But it only requires 10% of the power that a desktop PC requires! If your laptop does not have an eSATA port you can buy an express card adapter which gives you eSATA capability and an eSATA to SATA lead to connect it to the HyperDrive5.

Use HyperOS 2009SE SuperGeek to clone Windows from your hard disk to your HyperDrive and then surf the net entirely on your HyperDrive and do not use the lithium battery backup or the external DC adaptor. Then whatever virus or spyware or cookies or malware or zombieware or other clutter you accrue during the session will be forensically wiped at the end of the session by powering down your PC. So each time you surf the net you start anew. Only a DDR SSD can do this. Hard Disks and Flash Disks retain data even after that data has been deleted and overwritten several times.

Suggested Configurations...

Simply install Windows and run it on the HyperDrive5  if you like. It will install very quickly - around 8 minutes for XPSP2. In this configuration the HyperDrive should be primary and bootable. You would attach the HDD as a second primary bootable device but choose to boot from the HyperDrive in the BIOS. With this configuration you should use the DC adapter so that the HD5 does not lose data if the PC is powered off.

Alternatively add the HyperDrive5  as a second SATA disk. Then it can act as a photoshop scratch disk or a general high IOPS work space. You can achieve instant Windows in this configuration by using HyperOs 2009SE Geek or SuperGeek to clone a system from the HDD to the HD5. For true RAM performance please ensure that the paging file is running on the HyperDrive and not on the boot drive. Then you will get an incredibly fast Windows boot up and an instant desktop. The PC will still be booting from the Hard disk but will only look at that drive for the MBR and the boot files, which will not delay the boot significantly.

Thereagain you can use a full disk cloning program and clone your main system onto the HyperDrive so long as your main system is small enough. Then either connect your HyperDrive as a second SATA disk or if you like as the first SATA disk and move your HDD to the second SATA port. You can then choose which one to boot from using either the BIOS or the Windows boot menu, or using HyperOs 2009SE Geek or SuperGeek if you have them installed.
