Intel SSD 710 Tested: MLC NAND Flash Hits The Enterprise

Sequential Performance Versus Transfer Size

There are a number of enterprise-oriented workloads that push a lot of random data. Exchange information stores and online transaction processing are both good examples. Sequential tasks might include writing out log files or backing up data to disk. Either way, though, you're going to see more outstanding I/O operations using those applications than in a desktop environment, and that's why we're configuring ATTO to use its maximum queue depth of 10.

At high queue depths, RAID really delivers better performance at smaller transfer sizes. There is a performance overhead incurred with every page request (8 KB), so scaling up using striping is the only way to improve our results in that discipline.

While the RAID array stands apart in read operations, it's not as dominant in our write test; the SSD 710s deliver about ~40% more performance. In a single-drive configuration, the 710 continues to perform like the 320.

SandForce's compression technology really puts things into perspective, as the Vertex 3 leaves other SSDs in the dust at transfer sizes greater than 32 KB. It's the only SSD of the group to easily break through the 500 MB/s barrier, though it relies on the fact that ATTO uses compressible data (like log files) to achieve those numbers. Subject the same drive to incompressible data at the same queue depth and throughput drops to about 240 MB/s (using 128 KB blocks) instead.

    TLDR; Although expensive, the drives offer greater amounts of data transfer, reliability and expected life - however, they cost a f'ing arm and a leg (even for a corporation).

    Expect these to be the standard when they've dropped to 1/3rd their current price.

    To some companies or institutions.. The data this devices hold far outweighs the prices of this storage devices..

    I think the writer missed the whole point on this article.

    What happens when you RAID5 or RAID1 the SSD's??
    I don't think any enterprise would trust a single SSD without RAID.

    Nice. Now let's see how many comments complain about the price. :sarcastic:

    __-_-_-__with the reliability those have they will never ever find their way into any serverMy Vertex 3 has been very reliable and I'm quite satisfied with the performance. However, I've heard reports that some, just like with anything else, haven't been so lucky.

    I thought ssd drives were unreliable because they can die at any moment and lose your data, and now I see that they're used for servers as well? are they doing daily backups of their data or have I been lied to? ;(

    halcyonSSDs are generally accepted to be more reliable than HDDs...at least that's what I've been lead to believe.Yes, but when they die, that's it; you're done. You can at least send a mechanical HDD to Ontrack (or a competing data recovery service) with a GOOD chance of getting most or all of your data back; when a SSD bricks, what can be done?

    nekromoboI think the writer missed the whole point on this article.What happens when you RAID5 or RAID1 the SSD's??I don't think any enterprise would trust a single SSD without RAID.The assumption is that ALL servers will have raid. The point of this article is how often will you have to replace the drives in your raid? All of that down time, and manpower has a price. If the old Intel SSDs were about as reliable as a traditional HDD, then that means that these new ones will last ~30x what a traidional drive does, while providing that glorious 0ms seek time, and high IO output.
    Less replacement, less down time, less $/GB, and a similar performance is a big win in my book.

True, when the drive is done then the data is gone, but real data centers all use RAID, and backups for redundancy. Some go so far as to have all data being mirrored at 2 locations in real time, which is an extreme measure, but worth it when your data is so important.
    Besides, when a data center has to do a physical recovery of a HDD then they have already failed. The down time it takes to physically recover is unacceptable in many data centers. Though at least it is still an option.
