Fine, let's deconstruct your post:

"Theyre slower (r/w) speeds than normal drives AND they cost more, so why do people get them?"
They are NOT slower than normal drives in random speeds... where it actually matters.


"http://www.newegg.com/Product/Product.aspx?Item=N82E16820167047"
That is a Intel 320, not X25-M.


"This is a perfect example, 90mb/s write, my HDD has better speeds than that."
Sequential write.... again.. s-e-q-u-e-n-t-i-a-l writes. Already and repeatedly stated that this is of low importance to most users but you insist on using it as your one and only performance metric.

"not to mention 25nm NAND."
What's your point?


If you want to discuss the cost of a particular SSD, then why are you not comparing it to other SSDs? Stop trolling or you will recieve an infraction. People are providing constructive response but you are insisting on your limited point of view. In fact, your entire OP is flawed in understanding or is purposely flamebaiting.
25nm degrades quicker
since we were talking about SSD's i assumaed your logic was powerful enough to realize that i meant normal SSD's, or solid state DRIVES

Not really true, since:
1)You can convert random writes to sequential 99% of the time
2)Random reads can be covered by cache "most" of the time
3)After a couple of days of writes, an SSD is down to a fraction of its optimal performance

Pretty sure that is false. I have a few benchmarks where my performance has even gone up marginally even after a year.

Proof?

I think a couple of days is a bit of an exaggeration, but its a well known fact that SSD's degrade over time. Especially the 25nm versions.

That is what TRIM and Garbage Collection are for, which most modern SSDs have.

HMM.. Here's mine:

Apparently if you buy tons of cheap SSDs they tend to work quite competently together

25nm NAND is rated for 3000 P/E cycles minimum so this is 5-8 years for typical consumer usage. Furthermore, the NAND is still readable for at least one year after it no longer can be written to. This 25nm arguement is a moot point.

Logic has nothing to do with power. It is what it is.

What are you talking about? Define "normal" SSD? Intel SSDs are known for their reliability and brand name.


And again... why are you blaming me for bring in HDD when you did so in your OP? And again again.... why are you only considering one benchmark? You still have not addressed those two point so stop picking and choosing.

1) Yes, but why would you as it would increase write latency and read latency. To convert random writes to sequential, you would have to wait until to queue up a few write blocks before writing. When bundling random writes together, there is no way of ensuring that this data is related so when a read occurs later.... it has to be a random read instead of sequential.
2) Depends... are you talking about RAM or disk cache? The intial read of data has to be done to place data into cache. Larger programs like Visual Studio or Photoshop are larger than disk cache.
3) That is why TRIM and garbage collection exists. The performance impact of writes is now less than 5% for all current SSD. The only time it might be an issue is if you hit your drive with massive random writes and/or there is little spare disk space left. The number of random writes required for an issue is not real-world consumer usage.

They have answered it by telling you that random > sequential. You pointed to sequential writes as your arguement for your HDDs being faster, people here responded by pointing out that aside from the sequential writes, the Intel SSD is faster in every other way and in many cases by a great margin.

If your PC usage is such that having fast sequential write speeds is of great importance and more valuable to you than any other area of drive performance then yes I guess the Intel X-25 would be a bad buy.

First off youre either trolling or blind. I never mentioned ONCE in my OP the word (or acronym) HDD. It was in fact YOU who ws the first to bring up a benchmark of an SSD vs a velociraptor, thus derailing the entire thread.

So just close this thread i have my answer and u had ur troll.
