Adaptec RAID 1800 He added that he would not be able to write on-the-fly. Let's start with SATA drives with a fairly large amount. The graphs this time Adaptec RAID 1800 be separate - the speed and delays for each of the four test scenarios. On sequential read operations, the array shows stable results regardless of the type of cache used, which is quite expected. Recall that in reading the array of hard drives showed a maximum of about IOPS, but at this boundary, delays have already begun to exceed ms.
In the operations of random recording, we see the greatest effect - the growth of indicators by two and a half times with a simultaneous increase in load capacity. When Adaptec RAID 1800 the cache, you can have delays of up to ms with two to three times more threads.
General conclusion on this configuration: Let us now look at the variant of the caching Adaptec RAID 1800 of the second pair Adaptec RAID 1800 SSDs. On sequential reading, the results do not differ from those given earlier, which is quite expected. On the sequential write, we now have three groups - the configuration with Write Write cache lags behind, Instant Write Back shows approximately half the maximum speed, and only Write Back does not differ from an array without a cache.
The same alignment and with the waiting time.

At the same time, the wait time does not exceed ms, even with a large number of threads. Adaptec RAID 1800 last participant, who does not use the cache on write operations, shows about IOPS, just like an array of hard drives.
Perhaps the most interesting option for this caching volume is Instant Write Back. True, it is slower on streaming read operations.
It may be possible to fix this using the RAID10 configuration for the maxCache volume, but this will already cost four compartments in the storage enclosure. In general, we can say that the application of the maxCache technology can really be useful for improving the performance of arrays from hard disks, especially Adaptec RAID 1800 there are many random operations in the load. The manufacturer offers also five-year limited warranty along with PSU.
