Hosted by: Scott Moulton of MyHardDriveDied.com and Steve Cherubino of Podnutz
Topics discussed:
New Seagate SSD (Solid State Drive)
Large drive, looks like a blade server, about 200GB in size
Handles 30,000 Read operations per second and 25,000 Write operations per second
SSD Intel-X25M handles 5,000 Read operations per second, priced around 1TB for $2,500, 512GB for $1,200
A normal 72rpm SATA drive handles 90 operations per second
SCSI drives handle 180 operations per second, they are more reliable and intended for servers
World’s fastest & most advanced memory card backup
The ioDrive is a revolutionary new solid state technology that dramatically increases bandwidth and application performance
Solid State device on a card, high speed (server based device), made by Fusion-iO
Flash on card, has its own processor for faster data processing
Handles 80,000 operations per second, largest ioDrive available is 80GB

Question:
Blaine
Q: Does Harmonic Vibration causes performance degradation in modern hard drives?
A: Scott ventures to say “No”, drives are supposed to adjust to their own environment; heat may cause expansion but small vibration will no degrade the performance.
Q: Can you please compare MHDD to SpinRite?
A: MHDD is free, uses a remap function (moves bad sectors to bad blocks section).
SpinRite reads bad sectors and will run complex read algorithms trying to recover such bad sector, writes to the same drive
Media Tools Pro writes to a different destination drive (much better than SpinRite)
