Pros: Purchased this drive for use as a SLOG on an HDD-only ZFS RAIDZ array. Unfortunately, it's one of the few SSDs that's really able to support the use case without the possibility of data loss, due to the employment of power loss protection capacitors. But what an SSD!
The individual drive specs are well-published elsewhere, so I won't repeat them here. But for use as a SLOG device, marvelous. After adding the SLOG, 4K random write over sync NFS, my throughput raised from around 2MB/s to around 30MB/s. Similar increases in throughput throughout the write range.
I'm using the array as a VMware datastore, via sync NFS share. Prior to adding the SLOG, write operations in a VM were unbearably slow. Access times varied wildly, and maxed out in the 1-2s range. Now seeing access times averaging around 1ms (over 1Gbps ethernet) and spiking (rarely) around 12ms. Needless to say, I am very happy with the results.
Cons: None found so far.
Other Thoughts: Overall a much better choice than iSCSI or async NFS. The price is a bit steep, but I am happy I paid it. VMs are now extremely responsive, and consistent. Would be nice to see some other SSD makers put their focus on consistent performance and (!!!) power loss protection.READ FULL REVIEW
Pros: Works well with the new SAS3 HBA series from LSI. Note that this is the internal connector type.
Length was fine for reaching inside an Antec P180 case. I like how thin the cable is. It is pretty stiff, but that's not really a problem.
Cons: None noticed.READ FULL REVIEW
Pros: I was able to easily install and verify working via the HBA's BIOS. Updated to the latest firmware and BIOS using the EFI console and files from LSI's support site. All SATA III drives were detected correctly (3 WD Reds and an Intel SSD) by the HBA BIOS.
I installed the card on a Xeon box, intending for it to be used via passthrough in a ESXi virtualized environment (FreeBSD guest). The connected drives were available in ESXi, and in the guest OS when the RAID card was passed through.
Cons: Unfortunately, LSI has not released drivers for my guest OS, FreeBSD 9.1. I was able to compile the kernel with the drivers for FreeBSD 9.0 and connect to the drives successfully, however there were large numbers of errors in the system logs, so it is clearly not ready for prime time on that OS. FreeBSD 9.2 is out and considered production stable, so it is a little frustrating that LSI is so far behind in their driver development/validation process. No eggs taken off of the review, because my understanding is that those drivers are in works, and the supported versions are documented on the LSI driver download site. It took some digging, however, to find out that unlike previous LSI HBAs, the new SAS3 generation is not supported via FOSS drivers. More concerning is that they may not be for a long time due to a disagreement between the FOSS maintainers and the LSI developers.
Other Thoughts: Great product, paid the price for being an early adopter.READ FULL REVIEW
