What is better HDD or SSD?

So I want to get a new HDD/SSD because my PC takes ages to boot and is sometimes slow at opening programs, what is better HDD or SSD

    SSD's are getting cheaper, though at capacities well short of a typical HDD, but if you can live with a 64GB or 128GB capacity....

    The thing which IS left looking really silly, is the "fast" hard drives, like the WD Raptor / Velociraptor, as they are not that much faster than the "performance" versions of current hard drives, but lose out on capacity and are soundly beaten by SSD in speed.

    When using SSD though:

    1. Never defrag - it just puts extra write cycles on the drive, and the life of the flash media is measured in write cycles.

    2. If you have a hard drive and an SSD, put the swapfile on the hard drive - if you think you need superfast swapfile - ADD MORE RAM!

    3. It helps if your OS and drivers support "TRIM" - this allows deleted space on the SSD to be precleaned to allow faster write. When trim is not available, once all space on the SSD is "dirty", a slower wipe+write cycle is needed.

    Of course, a modern "performance" HDD, such as a WD Caviar Black, will be faster than previous generation drives - even the "Green" models can manage decent sustained transfer rates, but have slower seek times.

    Older generation SSD's tended to have impressive "seek" times, because there is no mechanical delay but less than impressive transfer rates, while modern SSD have greatly improved the sustained transfer rates, even for write.

    you can get faster boot times, SSD is better. SSD's are much faster than HDD's,but more expensive . no physical disk or mechanical arm doing the writing/reading like hard drives have.

    If you are looking to get faster boot times, SSD is better. SSD's are much faster than HDD's, as there is no physical disk or mechanical arm doing the writing/reading like hard drives have.

    However, solid state drives are quite expensive. Because of this, it's not uncommon to see an SSD as a boot drive, with HDD's used for storage (as data access doesn't take that long on an HDD anyway). If you are going with an SSD, I would recommend getting a 60-100 GB drive, using it purely as a boot drive, and storing everything on an HDD.

    Both SSDs and HDDs do the same job: They boot your system, store your applications, and store your personal files. But each type of storage has its own unique feature set. The question is, what's the difference, and why would a user get one over the other? We break it down:

    Price: To put it bluntly, SSDs are more expensive than HDDs in terms of dollar per GB. For the same capacity and form factor 1TB internal 2.5-inch drive, you'll pay about $60 to $75 for an HDD, but as of this writing, an SSD doubles that to $130 to $150. That translates into 7 cents per gigabyte for the HDD and 14 cents per gigabyte for the SSD. Since HDDs are older, more established technologies, they will remain less expensive for the near future. Those extra hundreds may push your system price over budget.

    Maximum and Common Capacity: As seen above, SSD units top out at 4TB, but those are still very rare and expensive. You're more likely to find 500GB to 1TB units as primary drives in systems. While 500GB is considered a "base" hard drive in 2015, pricing concerns can push that down to 128GB for lower-priced SSD-based systems. Multimedia users will require even more, with 1TB to 4TB drives as common in high-end systems. Basically, the more storage capacity, the more stuff (photos, music, videos, etc.) you can hold on your PC. While the (Internet) cloud may be a good place to share these files among your phone, tablet, and PC, local storage is less expensive, and you only have to buy it once.

    Solid State Drive

    Speed: This is where SSDs shine. An SSD-equipped PC will boot in seconds, certainly under a minute. A hard drive requires time to speed up to operating specs, and will continue to be slower than an SSD during normal use. A PC or Mac with an SSD boots faster, launches apps faster, and has faster overall performance. Witness the higher PCMark benchmark scores on laptops and desktops with SSDs, plus the much higher scores and transfer times for external SSDs versus HDDs. Whether it's for fun, school, or business, the extra speed may be the difference between finishing on time or failing.

    Fragmentation: Because of their rotary recording surfaces, HDD surfaces work best with larger files that are laid down in contiguous blocks. That way, the drive head can start and end its read in one continuous motion. When hard drives start to fill up, large files can become scattered around the disk platter, which is otherwise known as fragmentation. While read/write algorithms have improved to the point that the effect is minimized, the fact of the matter is that HDDs can become fragmented, while SSDs don't care where the data is stored on its chips, since there's no physical read head. Thus, SSDs are inherently faster.

    Durability: An SSD has no moving parts, so it is more likely to keep your data safe in the event that you drop your laptop bag or your system is shaken about by an earthquake while it's operating. Most hard drives park their read/write heads when the system is off, but they are flying over the drive platter at hundreds of miles an hour when they are in operation. Besides, even parking brakes have limits. If you're rough on your equipment, an SSD is recommended.

    HDDs are cheaper, but SSDs are faster, reliable and versatile. All 2.5 inch SSDs use NAND memory, the same memory found in USB flash drives. Samsung's and Intel's as well as Kensington's are the best you can get; one reason I like them, is that you don't have to defragment them.

    SSD is way faster than a HDD.

    your talking 3 times faster at least

    SSD for sure. I've been using one for 2 years now, could not go back to an HDD except for exteral storage...

    1. Completely Silent – Because there are no moving parts, Solid State devices make no noise with the exception of some of the higher end models that have an attached cooling fan.

    2. The random access memory of a Solid State device is quick, due to the lack of writing implement necessary to save the data.

    3. Solid State Memory has access times that are approximately 250 times that of the standard hard drive, making access time lag virtually imperceptible.

    4. Solid State disks can boot up over 25 times faster than the standard hard drive, since there are no disks that need to warm up.

    5. Little to no Mechanical Failure – Because there are no moving parts to an SSD, it is rare that any mechanical failure can occur, because there are no parts that can break. As such, SSD can withstand a great deal of movement and vibration – far more than the standard hard drive – without risking any broken pieces.

    6. The lower capacity SSDs (and presumably the higher end SSDs in the near future) require very little power usage and produce far less heat. While the higher end ones currently produce more than the standard hard drive, this is generally considered to be a result of their novelty and is expected to be rectified in the not too distant future.

    7. Clearly Understood Performance – Because Hard Drives can wear down at random speeds due to the life of their moving parts, estimating the life of a hard drive is somewhat difficult. With SSDs, however, it is easy to calculate how they will perform because there are no moving parts, so all of the pieces wear down at the same, pre-established speed.

    8. Most of the lower capacity disks tend to weigh less and can fit in smaller areas. Since most SSD are flash drive disks, up to 512 GB are lighter than their Hard Drive counterparts, and exponentially lighter as the capacity grows smaller (Hard drives tend to require the same components regardless of the capacity, resulting in increased weight and size).

    9. Many models contain batteries that allow them to be saved/backed up in the event of a power outage or transferred from computer to computer without losing data.

    10. Growth Potential – Unlike hard drives, as SSDs start to grow in popularity, their disk space is expected to increase with it without the performance or speed being affected. In addition, the space required to maintain these SSD when they grow is expected to be less, making them ideal for laptops in the near future.

    Both. SSD for the operating system and programs and standard hard for media files. Because SSD-it has a number of records.

    SSD is better, hands down.
