no moving parts is another advantage of SSD.
I personally think they have a lot of advantages over HDDs. speed, reliabilty, performance.

Reliability isn't one of them.

Actually, reliability is most certainly one of them.   HDD's being mechanical are far more susceptible to failure under general operating conditions than are SSD's.   And even then SSD's are being being used in harsh environements now because they aren't effected by temperature, pressure, noise and vibrations like HDD's are.

Now if you plan to write 1 TB of data to the drive every single day, then an SDD may not last as long....unless you have good wear leveling and over provising software built in like Samsung does.

That's only really for people whose time is worth the money i.e. a programming, developer etc.

The regular joe/janes are better off with HDDs unless they just have money to blow.

Throw a $60 60 GBB SDD into a regular computer as the OS/Boot drive and they'll notice a huge difference in boot times, program start up times, virus scans, etc...

 

As for this SDD specifically, it will likely retail for between $550 to $650.  Samsung is selling some SDD's for $0.65 per GB and these are coming on a smaller memery process meaning costs are reduced.   Granted those are still high prices but an SSD of this capacity isn't developed for every day web browsing, MS Word and email usage anyway.


Was about to say that but you beat me to it.

Agreed. Every PC, even your grandmothers should have an SSD, amazing pieces of technology which makes any PC incredibly responsive.

However, keep in mind these will be using cheap TLC NAND and not just any TLC NAND either, 19nm TLC NAND which means worse latency and longevity.
I prefer to stick to MLC/SLC NAND SSD's if I can.

Samsung's NAND is some of the best.  Not sure where you get the idea it's cheap.  This also 10 nm, not 19 nm.

They've performed longevity tests on modern cell performance and it's now far and away beyond what original longevity tests showed back when flash was first coming to market.  The early SSD tests were not much better and in both, RAM was never taken in as a factor which actually plays a huge role in the longevity of your SSD.

Most longevity tests are actually still based on the old Compact Flash drives.  Those being much smaller in capacity and of older technology did indeed have issues with short cell lifespans but that's really no longer an issue.  Especially with larger drives (meaning fewer write cycles per cell over time), better wear leveling software, great over provissioning software and finally...computers with more RAM which leads to far less paging on the SDD.

It's "10nm class" but actually 19nm.

Samsung did the same thing by stating 28, 22 and 21nm as 20nm aka. "20nm class". - Advertising at it's finest, sorry you fell for it.

In regards to longevity, you're right RAM, SSD controller and other factors play a massive role, but you still have Physics come into play which simply, you cannot get around. (Simply, MLC and SLC will generally have far higher endurance than TLC at the same node.)

For those saying SSD's are pointless, you can get a 64GB drive for your OS for like $80 and your pc loads up in Its a huge jump and well worth the price



Current Game Machines: 3DS, Wii U, PC.

Currently Playing: X-Com(PC), Smash Bros(WiiU), Banner Saga(PC), Guild Wars 2(PC), Project X Zone(3DS), Luigis Mansion 2(3DS), DayZ(PC)

All yours for the amazing value of $1000!(not the real price, but i guessed here) But seriously, SSD's are pointless until they become as cheap as traditional hard drives. Nice to see them in such large sizes though

Why would they need to be as cheap as traditional hard drives? They are significantly faster. A single SSD might be the best investment for many PCs these days.

Because otherwise they are not really viable. I though SSD's would replace Hard Drives in the end but that won't happen until SSD's are cheaper. People don't want to pay more for their computers than they do now.

SSD's may be significantly faster but they hold very little space and are very expensive (up to 10x more costly than a hard drive of the same size)



Xbox Series, PS5 and Switch (+ Many Retro Consoles)

Prediction: Switch 2 will outsell the PS5 by 2030

will there be any benefits for console gamers?
6GBps sounds very good and could break down(ps4-xb1) loading times to 1 second .

I didn't see the "class" part but based on some research, it's most likely going to be 16 or 14 nm, not 19.  Samsung has been working on both 14 and 16 for a while now but nothing about 19 nm.  Only Toshiba is working with 19 nm right now.

Of course SLC and MLC have a highe rendurance than TLC.  I never said otherwise.  In fact, I was speaking about SSD's in general with regards to their mechanical counterparts.  I wasn't comparing the different cell technologies.

I did, however, get the price correct.  The 1 TB model is $650.
