I was looking up SSD prices and storage sizes when I came accross something called a hyperdrive 5. I have never heard of one before. The website bigs them up though. Are they asny good?
From the website
The HyperDrive5 is the fastest Internal Hard Disk in the World from a seek time perspective.
It has less than 10 microseconds read access time and less than 10 microseconds write access time.
It does not - as the best Flash SSDs claim - offer... 'RAM-like performance.'
It offers RAM performance.
If that doesn't solve your IO bottleneck nothing will!
800x faster at finding files than a 10,000 rpm SATA WD Raptor WD740ADFD
125x faster at serving files than a WD Raptor.
The HyperDrive5 is a Solid State disk made not from Flash RAM but from DDR2. HyperOs Systems have teamed up with with Taiwan to provide the World's best value DDR SSD at $449 (£299). DDR2 is still hundreds of times faster than commercially priced Flash RAM at write IOPS. Although Flash drives have caught up as regards Sustained Transfer Rate. Flash drive specs rarely quote random write IOPS. But for database applications and software compilation and photoshop and video editing that is the real bottleneck.
The HyperDrive5 is faster than all Flash Drives because DDR2 has both read seek times and write seek times measured in nanoseconds. Whereas flash drives have very poor write seek times and poor write overheads on top of that. Neither do they perform to their published specs. For example the FusionIO drive, the fastest Flash drive in the world, which is not bootable and runs through the PCI express bus, quotes 120,000 IOPS, but its Toms Hardware review shows 30,000 IOPS as measured by Intel's IOMETER. The HyperDrive5 manages 65,000 IOPS measured by Intel's IOMETER (on a MOBO with a good SATA controller and good Southbridge BUS driver). So it is twice as fast as the world's fastest flash drive (which costs several thousand dollars) at processing lots of small files
