Dose phone memory work like a ssd

Recommended Posts

Posted · Original PosterOP

I was wondering if cell phone memory works like a ssd? Where it has a number of times you can rewrite it before its drive starts to fail.

Yes, it's flash memory so eventually it's going to die.

...is there a question here? 🤔

Sauron'stm Product Scores:


Just a list of my personal scores for some products, in no particular order, with brief comments. I just got the idea to do them so they aren't many for now :)

Don't take these as complete reviews or final truths - they are just my personal impressions on products I may or may not have used, summed up in a couple of sentences and a rough score. All scores take into account the unit's price and time of release, heavily so, therefore don't expect absolute performance to be reflected here.


-Lenovo Thinkpad X220 - [8/10]


A durable and reliable machine that is relatively lightweight, has all the hardware it needs to never feel sluggish and has a great IPS matte screen. Downsides are mostly due to its age, most notably the screen resolution of 1366x768 and usb 2.0 ports.


-Apple Macbook (2015) - [Garbage -/10]


From my perspective, this product has no redeeming factors given its price and the competition. It is underpowered, overpriced, impractical due to its single port and is made redundant even by Apple's own iPad pro line.


-OnePlus X - [7/10]


A good phone for the price. It does everything I (and most people) need without being sluggish and has no particularly bad flaws. The lack of recent software updates and relatively barebones feature kit (most notably the lack of 5GHz wifi, biometric sensors and backlight for the capacitive buttons) prevent it from being exceptional.


-Microsoft Surface Book 2 - [Garbage - -/10]


Overpriced and rushed, offers nothing notable compared to the competition, doesn't come with an adequate charger despite the premium price. Worse than the Macbook for not even offering the small plus sides of having macOS. Buy a Razer Blade if you want high performance in a (relatively) light package.


-Intel Core i7 2600/k - [9/10]


Quite possibly Intel's best product launch ever. It had all the bleeding edge features of the time, it came with a very significant performance improvement over its predecessor and it had a soldered heatspreader, allowing for efficient cooling and great overclocking. Even the "locked" version could be overclocked through the multiplier within (quite reasonable) limits.


-Apple iPad Pro - [5/10]


A pretty good product, sunk by its price (plus the extra cost of the physical keyboard and the pencil). Buy it if you don't mind the Apple tax and are looking for a very light office machine with an excellent digitizer. Particularly good for rich students. Bad for cheap tinkerers like myself.

Both are flash memory so yes, in that sense they are the same.

Fine you want the PSU tier list? Have the PSU tier list: https://linustechtips.com/main/topic/1045610-new-psu-tier-list/

Smartphone, Tablet, SmartTV, and pretty much every cell phone and PDA since 2004 use NAND flash memory as secondary storage (eg disk) space that is soldered to the device's PCB.


SSD's, USB drives, and SD cards (and their various form factors like MMC, transflash) and similar devices used by cameras and camcorders are also NAND flash based storage devices, but are typically a little more elaborate due to needing to be removable/installable/replacable. For example the Panasonic P2 and the Sony SxS are also flash media, but in more ruggedized forms.


In general, everyone moved towards UFS, and the cards for these only started in 2016. UFS are basically "SSD"'s in a microSD style memory card shape, though many devices with internal storage are using it internally. 


So in short yes, your smartphone has a soldered in SSD.

Only real difference between what's used in phones, and what's used in larger machines is the parallelism, or lack thereof. Desktop SSDs achieve high throughput from having many individual NAND devices on board. While smartphone SSDs may only be a single device, and thus not blessed with gobs of throughput, the latency remains undiminished, and random read/writes are still quite high. Only thing you're losing is file transfer speed, and possibly game loading times.
