Hardrives SSD

[team illucid]

It is 3D NAND chipsets. The drive is half the size of an Evo

FWIW - just checked my records - my 1TB Transcend SSD370 was just under $A500 inc shipping in June. http://www.bhphotovideo.com/c/search...385+4291132620 (inc mount)

Recently had 2 sata drives cook themselves in succession. Using some spares atm though need to buy two more. Looking at some ssd sata drives.
Presently have 2 conventional sata 1gb though not using that space. Can anyone recommend a particular brand/quality probably 480gb would suffice depending on price I may even go with
3 x 240gb as I do use remote storage as well.

Hello, I know this is way late but I hope it will help someone out there.
Samsung has got it right with their SSD drives, they have three sets of chips others brands only have two. Try going to their website and that will help make things clearer. They also have a very large range of drives.

If you are still not sure then compare their spec's against any other brand.
You will find that their prices are just as good as any other brand. I get my drives from Umart, they have very competitive prices all round.
One of the most important thing is "PLEASE DO NOT DEFRAG ANY SSD DRIVE OR YOU WILL DESTROY IT"
Use a Samsung 840/850 series 120/256/512Gb or larger SSD drive for media software, programs and games etc where you need speed and power, for files/photo's/video's you want/need to keep safe then use a standard 1,2,3Gb hard drive to store safely. Use a brand you have used before or that you trust.
Anyway. A dollar short and a few years late but so long as this stops anyone from defragging their SSD then it will be worth it. Cheers Bill (Come Lately)

Samsung have software that comes with their SSDs (Samsung MAGICIAN.. funny name) that allows you to sorta defrag,,.. probably better to say optimize/maximize the performance of their SSDs

The other thing you have to do.. is to turn off 'Windows Indexing' on any SSD drive one installs

What an utter load of BS.

The issue you're referring to is the fact SSD's only have a finite number of write's per memory block, so defragging uses up writes unnecessarily but you would literally have to defrag the disk constantly to eventually kill it.

For people reading this wondering why we don't defragment drives anymore it's important to understand why drive defragmentation was ever used.

OLD HDD's

Back in the old days drives worked like a record player. So if you had some data stored on the very edge and then needed to load some data in the centre there was a time delay for the head to move from one location to the next (: hard disk seek time).

Over time you would end up with data dispersed all over the drive with frequent gaps where no data was stored. Defragmenting a drive packed all the data into adjacent storage locations so if your drive was 50% full, only 50% of the drive surface would be used. This meant the head didn't need to traverse the other 50% of the drive whatsoever since there was nothing stored there, thus making for better performance.

It's a bit like having 100 filing cabinets in a row and you've got a few documents in all of them. By moving all the documents into the first 5 cabinets you save a lot of time walking to cabinets that are further away.

SOLID STATE DRIVES

These days hard drives are basically just like large digital camera storage cards. There are no moving parts and the time to retrieve data from various locations on the drive are identical. This means if you have 100GB of data spread over a 1000GB of memory locations there is no speed difference since the physical vicinity of the data to each other doesn't matter.

The downside to SSD's is there is a finite number of times each memory block can be re-written. Think of it like you have a piece of timber and every data write is like scratching your name into the surface, and every re-write is like sanding your name off and scratching something else into it. Over time the timber gets thinner to the point where there is none left. This is how SSD's memory blocks work. Modern SSD's are smart and they work out which blocks have been exhausted so they stop using them. If you used an SSD for long enough the overall storage capacity would decrease as data blocks expire.

But how long would this take? A test was done recently and the best performers took continual rewrites of over 2 Pentabytes of data (ie: 2000 Terabyes). Modern SSD's also have built in algorithms which even out the storage cycles on each data block so that you don't see premature losses on blocks that have been used more than others. To kill an SSD you're looking at between 12 and 18 months of around the clock re-writes so in reality it is a non-issue.

Interestingly most new SSD's come with "overprovisioning" whereby spare memory blocks are included (but not used) so that if any memory blocks expire the spares are bought in to service to replace them to avoid capacity loss over time.

"What an utter load of BS." A mature reply from C4B.
So much for being civil, I could return compliment but they ask us to be civil to each other on this site.
You have, in a round about way said exactly what I said but you have gone into it as if everyone knows what you are talking about. A lot of people will only install a 120-256Gb SSD drive because of prices and that's what is be forced onto them. People are asking for advice because they are not technicians as you MUST be.
We could keep giving technical advise (in a civil way) until we totally confuse everyone and they give up trying to learn. I am just trying to give them advice they will understand. You try doing what you have said about defragging on a OCZ, Kingston, Intel or any other 120Gb SSD drive and let us know how you fare.
I rang Samsung a while back and they made it clear to me that you should not defrag their SSD drives because of exactly what you have said but we weren't talking about a 1Tb SSD.
I have also talked to other suppliers like Umart and others and they told me the same thing but hey it’s you drive so you can do what you like. I was just informing members as to the what can happen. I for one will urr on the safe side.
If people take your advice are you prepared to replace their drives.
You could have just posted your views as a alternative instead of being a whatever.
