  1. Hybrid Hard Disk Drive Radhika Patel

  2. Basic Terms • HDD (Hard Disk Drive): storage center for data • SSD (Solid State Drive): same thing as a hard drive, but with no moving parts Example: USB flash drive, internal memory on cell phones and cameras

  3. HDD • A hard drive is cheap and that’s why consumers prefer that option. • Typical price range for a HDD is $74.99 to $120.99 for a terabyte (1024 GB). • The typical cost of a HDD is about 7cents per GB which shows its extreme cheapness.

  4. HDD continued • Performance of a HDD: Base speed of a low-end hard drive is 5400 rpm (revolutions per minute) and a high-end hard drive would be 7200 rpm. • The faster the disk spins, the faster the computer performance will be. In other words, the boot time and/or loading applications will be faster, hence more heat generation.

  5. SSD • It will boot the operating system much quicker and applications will appear much faster since it has no moving parts. Compared to the HDD, SSD produces little to no heat. • Price: Ranges from $130 for 40 GB to $800 for 256 GB. This gives us an estimated cost of $3 per GB.

  6. Comparison HDD SSD Speed: faster as there are no moving parts Cost: expensive Reliability: technology is fairly new, can operate reliably in harsh environments as there are no moving parts • Speed: slower than SSD • Cost: cheap • Reliability: technology is mature and failures are rare

  7. Comparison cont. HDD SSD Storage Capacity: 256GB and 512GB becoming available, thus less storage capacity available • Storage Capacity: 1TB+, more storage capacity available

  8. Hybrid Hard Disk Drive • HHDD combines the disk of a HDD and the memory chips of a SSD. • Combines the performance of the SSD with the price and capacity of the HDD, hence the term Hybrid Hard Disk Drive. • HHDD uses 128MB or more of high speed flash memory (embedded in hard drive). • So, when booting a PC, operating system loads data from flash memory first, speeding up boot time and also removes need to quickly spin up the drive (saves power consumption). • Expect HHDD to come out in end of 2010 or beginning of 2011.

  9. Pros/Cons • Much cheaper than SSD • Higher performance • Product hasn’t came out so we don’t know if it is good or not • Not much information has been revealed regarding the new HHDD’s • All information revealed are estimations
