It means that it has both SSD drive in for caching and frequently used files and plate-based hard drive for all other files.
Hybrid hard drive
An SSD (Solid State Drive) is a type of hard drive that uses no moving parts, but rather stores data on Flash chips, similar to a Flash drive or CompactFlash.Solid State Drive
A hybrid hard drive is a Hard Drive that has a SSD built into it also. There is currently only one manufacturer that does it- Seagate. The Hard drive is a standard 7200 rpm drive(in flavours of 250, 320 and 500gb) and the SSD component is 4gig. The 4 gig ssd does not sound like much but the impact it can have is enormous. It has some onboard chip that evaluates your running processes and then puts your frequently used ones onto the ssd. I have a mac with a 5400rpm drive. I swapped it out with a hybrid drive and the increase in speed is great. Much much cheaper than ssd's and in my opinion hybrid drives are going to dominate the market for the next few years until SSD prices come into line with current Hard Drives.
HDD stands for Hard Disk Drive. SDD stands for Solid State Drive.

If you're replacing the old drive with the new one - you'll have to re-install every program - and copy any saved game (and other personal data) onto the new SSD drive.If you're adding an SSD drive as an extra storage device, you can leave all your programs on the old drive - and just move any user data to the SSD. It's entirely up to you as to how you go about it.
That 128GB drive is actually an SSD not a Hard Drive and no it isn't possible to replace the internal drive in a mac
ide hard drives are the old, slower, less capacity drives. sata are the modern, faster, large capacity drives. and ssd are the new, MUCH faster, medium capacity drives. ssd stands for Solid State Drive. it has no moving pieces inside. its basically a flash drive but in hard drive form. ssd's are also very durable u can drop them and they wont be damaged. ide drives have moving parts in them therefor the read/write head can scratch the disk easily if it is dropped and if shaked very hard it cna be damaged also. ssd's are VERY expensive though.
No, unless it's an ssd drive, at which point it would no longer be a "disk drive".
i really dont know help please
The RPM of your hard drive. A 7000RPM drive is faster than a 5000RPM drive, and an SSD is faster than all Platter hard drives.
