Power Consumption
Like I mentioned on the introduction page, the Vector 150 doesn't support any form of ACHI Link Power Management (also known as HIPM and DIPM) nor does it support Windows 8's DevSleep. Even with those disabled, the idle power consumption ends up being higher than Samsung's although it's good to see that OCZ has done some improvements compared to the original Vector. Power consumption under load, on the other hand, is very good as OCZ is able to stay within their 2.5W spec.

I have 2 60GB Vertex 2 in RAID-0 that I bought in 2009, that I still boot to as of today with no problems.profquatermass - Friday, November 8, 2013 - link
Me 2!A Vertex 3. I think most people don't bother ensuring they've got current Firmware in them when buying from a shop.
Shops (brick or online) are notorious for keeping old stock on their shelves.
Also make sure it is partition aligned correctly.

I've been using a 128 GB Vertex 3 since they launched it back in 2011. It had the blue screen issue but that got fixed after a firmware update. It's been working great ever since. Too bad for OCZ, looks like they're beyond hope at this point. Based on the comments their reputation has been soiled, and they'd need a miracle to keep going.derzerb - Thursday, November 7, 2013 - link
I've been using ocz products in several builds psu/ssds and never had any issues. The current affordable prices for ssds is partially attributable to ocz's aggressive pricing in the past.mayankleoboy1 - Thursday, November 7, 2013 - link
isnt the metric "4k random read at QD=1/2the only relefant metric for 80% of a typical desktop workload ?
In that metric, Samsung 840Pro still rules.

Exactly correct. QD 1-3 are all that matter....not Destroyer benchmarks with insane workloads.Gigaplex - Friday, November 8, 2013 - link
I'm confused as to why the 4K random reads are so slow. Much slower than writing. Anyone care to explain?Kristian Vättö - Friday, November 8, 2013 - link
Random writes can take advantage of write combining (i.e. small IOs are combined to make look like one big IO), which in turn will allow higher level of parallelism as the operation can be spread to a number of die.With random reads that is not possible because when the host sends a read IO request, the controller can't wait to combine it with more reads because that would add unnecessary latency (which means whatever you're doing will slow down because the OS is waiting for your SSD). Low queue depth random reads cannot take much advantage of parallelism because at QD=3, the controller can only read from three dies simultaneously (decrease QD to 1 and it can only read from one die).

Not bad in a review, but the review sample did die.While better alternatives exist, most people would avoid the OCZ brand like the plague, and that's the sad fact of the matter for OCZ.
I too can throw my anecdote into the ring with a Vertex 2 that gave random trouble. I RMA'd it, and the replacement sees only light duty in a seldom used laptop.

I have 2 ssd's, both would be considered the cheaper "consumer" quality, and usage would be considered very light. Would spending extra on an enterprise level ssd with higher warranty get me a drive that lasts a good bit longer?
