Solid State Drives?

Thanks for the info.
I will edit out my FUD!

Read cycles are not really limited.

Write and ERASE cycles are more limited.


That being said, with TRIM it gets better, and SandForce controllers are really working their sweat off to ensure longetivity of the SSD. It's a greater probability that HDD will suffer a mechanical error than SSD rendered unusable because of write-erase cycle limitations, especially in laptops.

I heard that TRIM is not recommended in many RAID configurations due to the way that LUN initialisation causes writes to all blocks in order to generate checksums.

However, this is an infant technology. In a few short years I'm sure these obstacles will have been negotiated.

I saw a press-release the other day for a 440Tb SSD RAID cabinet. I don't think it's actually available yet, but it's only a matter of time.

I think RAID is not really necessary with SSDs considering their performance (well, perhaps JBOD). Besides, some today's SSDs have internal RAID with two SandForce controllers.

RAID isnt always about performance. Data redundancy can be important too. And capacity. I'd always prefer to go 'proper' RAID rather than JBOD for either of those.

In the corporate/enterprise world, RAID has always been a matter of juggling various factors - performance, integrity, durability/reliability, scalability. Even today, multiple concurrent failures can still bite you. Remove the mechanical component from the equation and all of these factors are positively affected. As soon as this technology is accepted in the business world, the focus will shift to data delivery (faster networking, deduplication, etc.). Consumer systems will also evolve, perhaps to the point where no on-board storage is required, or maybe even thin-client

I think I'm wandering OT here
