The difference between SSD and HDD on server.

[Edison thomas]

1.Reading and writing speed
SSD read speed can reach 400M / s, writing speed up to 130M / s or more, and the Speed of server is 3-5 times than HDD.
2.Seismic capacity
Seismic capacity HHD of is poor due to HHD high-speed operation of the internal hard disk heads.It is generally a mechanical hard drive or electrical shock if it is used in sports, it is easy to damage the hard disk.But SSD storage solutions use chip inside without heads,so it is superior seismic capacity.Even with the movement or vibration , and not easily damaged.
3.Price
Generally speaking,The price of SSD is higher than HHD.
4.data recovery
After deleting the data on SSD ,you can not recover them by data recovery software.while HHD can be identified by general professional data recovery software to retrieve.

HDDs
• Enthusiast multimedia users and heavy downloaders: Video collectors need space, and you can only get to 4TB of space cheaply with hard drives.
• Budget buyers: Ditto. Plenty of space for cheap. SSDs are too expensive for $500 PC buyers.
• Graphics arts: Video and photo editors wear out storage by overuse. Replacing a 1TB hard drive will be cheaper than replacing a 500GB SSD.
• General users: Unless you can justify a need for speed or ruggedness, most users won't need expensive SSDs in their system.

SSDs
• Road Warriors: People who shove their laptops into their bags indiscriminately will want the extra security of an SSD. That laptop may not be fully asleep when you violently shut it to catch your next flight. This also includes folks who work in the field, like utility workers and university researchers.
• Speed Demons: If you need things done now, spend the extra bucks for quick bootups and app launches. Supplement with a storage SSD or HDD if you need extra space (see below).
• Graphics Arts and Engineering: Yes, I know I said they need HDDs, but the speed of a SSD may make the difference between completing two proposals and completing five for your client. These users are prime candidates for dual-drive systems (more on that below).
• Audio guys: If you're recording music, you don't want the scratchy sound from a hard drive intruding. Go for the quieter choice of SSDs.

Now, we're talking primarily about internal drives here, but the same applies to external hard drives. External drives come in both large desktop form factors and compact portable form factors. SSDs are becoming a larger part of the external market as well. The same sorts of affinities apply, i.e., road warriors will want an external SSD over an HDD if they're rough on their equipment.

Like a memory stick, there are no moving parts to an SSD. Rather, information is stored in microchips. Conversely, a hard disk drive uses a mechanical arm with a read/write head to move around and read information from the right location on a storage platter. This difference is what makes SSD so much faster.
