ssd vs hdd

[samzap]

what is the difrence between a ssd and hdd except the price and everyone saying that the ssd is better?

Most ssds are much faster. Generaly around 5x faster than a regular hhd.

SSDs are a ton faster. They're lifespan is also more predictable, they tend to take up less space, and they're more durable and aesthetically pleasing.

[RS2007GOD]

Also ssds arnt as prone to mechanical failure but to have a limited read/write lifespan but its a lot and will last as long as most people would want. Petabytes of of data.

I love SSD's in laptops due to less power consumption. 

 

For desktops you're not going to get as much of an advantage besides speed, but I'd recommend at the very least putting your OS on a small SSD and using a regular hard drive to handle the bulk of storage.

The difference between a sad and a hdd is that a sad as flash memory cells that can move data very fast but can wear out.  A hdd has platters that can be written and/or read from forever until some other part of the drive fails

On the surface, the main difference is performance. Most SSDs will achieve 500-550MB/sec on SATA and up to 2000MB/sec on NVMe, compared to up to about 150MB/sec on a good day for an HDD. However, I don't think that's their shining point. Their shining point is access time. SSDs can achieve 0.1us or less access time, whereas HDDs putter about 3-5ms. Most file operations are reads for small amounts of data, so having faster access time trumps transfer rate. As some measure of evidence, Microsoft reported regarding activity on the page file:

Quote

• Pagefile.sys reads outnumber pagefile.sys writes by about 40 to 1,
• Pagefile.sys read sizes are typically quite small, with 67% less than or equal to 4 KB, and 88% less than 16 KB.
• Pagefile.sys writes are relatively large, with 62% greater than or equal to 128 KB and 45% being exactly 1 MB in size.

 

In terms of the behind the scenes stuff, SSDs use flash memory which has a limited number of writes (about 10,000 or 1,000 depending on the type), but this is practically a non-issue. You have to write a lot of data and by the rate most people go at, the SSD will easily outlast the computer. The flipside though is since there's no moving parts, you can jostle an SSD all you want.

Regular hard drives as platters, as in spinning disks that are read by an arm with a needle on it (much like a record player). SSD's use a way different approach for data storage, they have memory sothered onto a 'motherboard' and the advantage with this is that SSD's are much faster (roughly 5-10 times faster, depending on what is being compared) and don't have moving parts inside, making them much less fragile.

 

This is newer technology and thusfar more expensive technology. It is very worth it for really all people, at least for installing Windows/other programs on it because everything installed on an SSD would start up a lot faster.

More speed and less noise. Oh what I would give to change my WD Black to SSD of same capacity (2tb).
