Hello,

I currently have a 1.5 tb external hard disk that has music videos and documents on it. i was thinking of transfering all of that on maybe 2 or 3 ssds. i add new content maybe 1 every week. so with this in mind, is it still neccessary to have 25% room free as is sujjested for a ssd for normal use?

Also, for above use, do i still need to get the intel ssd (which from reviews seems to be the best) or will any brand do?

EDIT: i often have to search through the entire document folder for small strings ( using the 'search text in files' search option in adobe ). will having those documents on ssd increase the time with which results are returned? right now, i have to wait for ~30mins before the search is completed.

Putting your documents on an SSD will greatly reduce search times, due to massive read speeds. However putting music and videos on SSDs is a waste of money for most people as they won't really load noticably faster, it's all down to the program.

As for brands, samsung crucial and intel are all solid choices. Avoid OCZ as they are famously plagued with problems.

I've never heard that you need to keep 25% free for normal use, I suppose it's beneficial as it means that the flash is less used and lasts longer. But if you are only reading then you don't need to leave space for over provisioning as reading doesn't wear out the flash.

SSDs are much more expensive than standard HDDs. So generally folks buy SSDs to increasing speed or shorten software and game loading time. If u have a lot money u could store tons of data into SSD anyway. But putting a lot of small files into SSD can shorten your search time.

Because I haven't really used a SSD ( u know budget betters) but Intel should be good enough though it's expensive. And never make a SSD full 'cause it would greatly slow down because of that.

I would have thought the same thing for videos but since my HD is reaching its capacity, when i fast forwards videos, sometimes it takes a while for the video to catch up with the audio. it is either moving very slowly or just remains static.

Also would the read only performance slow down like MAxime said? or is that only for write only?

25% may a bit too much to leave free, but SSD write speed is directly related to how much free space there is.

1) SSDs have a shorter lifespan then HDDs on reads and writes which in your case be a factor as your intending to read / write CONSTANTLY videos in the 10s is not hundred of Gbs weekly to daily, this is NOT what a SSD is for, especially as they are significantly more costly for the same amount of space a common TB drive can store.

2) Using multiple drives and search engines from a program (Adobe) is all relative to how the program was designed. Personally I use Everything, it is a freeware indexer, but if you use indexing on a SSD it again constantly reads the drive in 10s of GBs every minute thus killing the drive quickly. It is standard to turn off indexing and Virtual memory on SSDs.

3) personally I would just stick to a fast TB drive, say a 7200RPM, and use Everything to index it to pull the results faster.

I think you misunderstood. i will only transfer the 1.2 tb of data on 2-3 SSDs only ONCE. then i will add new content to it MAYBE once a week.

but to be honest, from the above replies, i think i will just get a faster HDD for the videos and music and only transfer the documents, ~200k pdf files totaling around 100gb, on a single 256 gb SSD (either samsung and intel). I also looked up the Everything software you mentioned and it specifically states it does not search file content, which is what i need.

Will searching file content, for example strings with in the text content of these pdf files, write anything on the SSD or is this a completely read only function?

Would of course be read (which is a problem for SSDs) and write if it hosts the Database that it will create on the same drive it works from (SSD or HDD) OR the drive it is searching from, which each time it does a search does a update and table consistency check of the DB (again a problem for SSDs wearing out).
