AnandTech Storage Bench 2011 - Light Workload
Our new light workload actually has more write operations than read operations. The split is as follows: 372,630 reads and 459,709 writes. The relatively close read/write ratio does better mimic a typical light workload (although even lighter workloads would be far more read centric).
The I/O breakdown is similar to the heavy workload at small IOs, however you'll notice that there are far fewer large IO transfers:
| AnandTech Storage Bench 2011 - Light Workload IO Breakdown | ||||
| IO Size | % of Total | |||
| 4KB | 27% | |||
| 16KB | 8% | |||
| 32KB | 6% | |||
| 64KB | 5% | |||
For lighter workloads that involve far less incompressible data, the 830 takes a clear backseat to the SF-2281 based drives. For nearly all users SandForce's real-time compression/dedupe architecture is a significant boon. You simply can't outperform a well designed controller that just writes less than the competition. The SSD 830 is at least significantly faster than the 470 and within striking distance (~10%) of the Intel SSD 510 and Crucial m4.

Compatability?As far as I am aware, Intel and Samsung were the only drives compatible with XP and every other OS out of the box
Am I wrong on this point?
I believe ALL other SSD's require Partition Alignment for compatability
It would be nice to get an update to see if ANY newer 6Gbps are compatible with every OS out of the box like the Samsung 470 and Intel drives
Is there a compatability list floating around somewhere Anand?
A Google Search turns up no reliability issues from anyone who actually knows what they are doing either
If you want to find hundreds of reliability or compatability issues, just visit the OCZ Forum or go read the Newegg reviews
or go sleep it off

EVERY SSD should be 4KB aligned for best performance.Out of Box Experience - Wednesday, October 5, 2011 - link
Intel and Samsung SSD's do not require end user alignmentOnly SSD's that do not have the offset in firmware require alignment

Quite a bit more juice running through them than the other drives - is this partly from the 256 mb cache?tipoo - Saturday, September 24, 2011 - link
Even the most power hungry SSD's don't require any additional cooling. It may look big on the graph, but that's still sucking way less power than most things in your system like the processor, graphics chip, etc. It just won't produce that much heat.sequoia464 - Saturday, September 24, 2011 - link
Thanks, Reason I asked is that My Toshiba based Kingstons seem to run (at least to the touch ) cooler than my both Intels and Vertex2's. (not that they are hot by any means, just warmer).Probably the workload and usage that is at play here - now that I think about it.

Different people have different concerns.Yes, if you install this in a desktop box power is not an issue.
If you install it in a laptop, the concern is probably not the thermal load but the maximum power draw. If your laptop is not specced to handle that, you'll find the machine crashing when you do a lot of back-to-back writes.
Same thing if you hoped to use it in a USB enclosure, whether USB2 or 3.

Probably a combination of things. Certainly, the DRAM is much larger than what is used by the other drives. Also, notice that this 512 GB version is being compared to 256 GB drives, so right off the bat its flash is taking twice the power as those it is being compared with. This was mentioned in the article. Samsung has not yet supplied a 256 GB version for testing. So I doubt it is a controller issue. Probably just the fact that it has twice the flash.infini - Saturday, September 24, 2011 - link
I don't think Intel is the king of reliability with the 8mb problem of the 320 series. Beenthere can you provide a link with compatibility and reliability problems of Samsug drives?
