What are the downsides of a solid state drive in comparison to atraditional hard drive?

From Quora, Franklin Veaux, Technology enthusiast, mad engineer, and tech startup founder. Money. SSDs are way, way more expensive than spinning rust. You can get a 2 terabyte spinning rust drive at Costco for $39. A 2 terabyte SSD is hundreds of dollars. Longevity. An SSD wears out. Every time you record information to it, you damage the memory cells. This problem is getting worse, not better. MLC drives wear out faster than SLC drives. The newest TLC drives wear out even faster. Drive manufacturers do all sorts of under-the-hood trickery, like moving information around on the drive, to help ensure all the cells wear evenly. Data recovery. As a result of this wear leveling, the operating system doesn't necessarily “know” where the information is stored on the drive; the drive controller and the drive itself keep track of that as they move files around to help make the drive wear evenly. If you're in a situation where your disk directory is corrupted or you overwrite the partition map or something, data recovery programs may not work. It is much easier to recover information from a spinning rust drive than an SSD. Information retention. If you save files on a spinning rust drive and on an SSD, stick them both on a shelf, and walk away, the information on the SSD will slowly evaporate as the charge leaks out of the floating gate transistors. Come back in five years and your spinning rust drive will likely be fine. Your SSD, on the other hand, may have incurred significant data loss, and there's a chance everything on it will be corrupted. Again, this problem is worse for newer drives. Hi Morningstar, I am cc'ing the w7 group, as the info applies to them too. Note is cross posting police: Bite Me! Indeed a nice analysis. SSD cons: they break, especially the cheap ones, completely dead and non-recoverable. SSD pros: additively FAST If you want to use an SSD, here are some of my guidelines: First, do not use SSD's if you are infected with CABDs. CABDs, also know as Cheap Assed Buzzard Disease (the "B" might not stand for "Buzzard"), will affect your outcome in a disastrous manner. And you know who your are! If you don't care about your data, find one on sale. There are times when your just don't care about things, like cache. If you care, a good quality SSD will greatly outlive a mechanical drive. As for "good quality", avoid Intel drives. From extensive research, I have found Samsung to be the best ones as far as I can tell. The ones I have used (not a lot so far) have been boiler plate. Their clone utility is so easy to use it is BORING. Their tech support is America based and is unbelievably good. Next, analyze your usage. For low usage, get a commercial drives: 850 EVO etc.. For intense usage or if you just want a long lived drive, get an enterprise drive: SM863a for lots of writes; PM863a for lots of reads. my 2 cents, -T |

Are there still new laptops available WITHOUT SSD?
I expect to need one shortly. -- |\ /| | \/ |@rk \../ \/os |

Also, considering there is (supposed) to be a Flash shortage right now, the manufacturer should temporarily go back to pushing HDD. Also, form factor matters. The thinnest devices get eMMC (flash soldered to motherboard). Ultra devices might get M.2 (plugin to motherboard socket). SSD on SATA port is further down the list. HDD on SATA port is at the bottom (sweet spot for sales volume). Paul |

Also, not as cheap will be a SATA SSD drive or an "economy" NVMe SSD drive. Both are about the same speed. A good (Samsung) NVMe SSD drive will be about 4 times faster than a SATA SSD. And I would recommend Lenovo's T (professional) series. http://www3.lenovo.com/us/en/laptops...pad/c/thinkpad They come with American tech support. You can get them custom with Windows 7 still, if that is your need. And be careful, they don't come with DVD drives anymore. |

Hi Paul, Now that I am Samsung certified (I do believe you had something to do with that -- thank you!), I can see inventories for Samsung at my suppliers. Where as Intel's junk is in very, very short supply, all my distributors have lots of stock on Samsung. But, they are a good 20% more expensive. You pay for what you get. -T |

Most do have SSD in the advertising folders I receive here. For me lifespan of the device and pricing ofcourse are more important than speed. -- |\ /| | \/ |@rk \../ \/os |
