Best SSD at 128gb?

Since most benchmarks people point to are done in the 256gb+ capacity, I'm wondering what the fastest 128gb drive is, since that's what I am getting.

From what I read, the Samsung 840 pro has poor write latency at the 128 gb size, so it's either the OCZ Vector or the PLextor M5 PRO Xtreme. The problem is, there is no reviews yet for the 128gb PLEXTOR m5 pro Xtreme. There are a few updated reviews that tested the regular m5 pro with Xtreme firmware, but the actual Xtreme version has hardware changes.

Anyone here who has experience with both the PLextor m5 pro Xtreme 128gb and OCZ Vector 128gb? The plextor looks appealing because it's price is reasable, and comes with a full kit, bracket and such.

I normally recommend Samsung due to their stellar track record. Crucial, Intel, and Plextor are also worth considering.

I maintain the ssd database listed in the sticky at the very top of this forum section. Here is the link:

Scroll down to the brands and models you are interested in and follow the links to the technical reviews.

BTW - The ssd database has links to 6 technical reviews of the Plextor PX-MP5 Pro Extreme.

In those reviews, it is either the 256gb version or the 128gb and not the Xtreme at all. (The closest one was the tweak town review which used the Xtreme firmware, but not the new Xtreme drive. ) I don't see a 128gb Xtreme in there.

In that TeakTown review they said: "As we stated before, the M5 Pro is one of the best, if not the very best, 128GB drives on the market. When you put it all together and test real-world applications that we use every day, the M5 Pro 128GB stands out from the pack."

and

"This was due to Samsung 840 Pro's high write latency after random writes. Vector also performed better when populated with data. So, it really comes down to Plextor and OCZ for the top spot "

and

"At the time of writing we can buy the Xtreme revision for less than the standard M5 Pro and at CES we saw the Xtreme benchmarks and it's faster.

We plan to have an M5 Pro Xtreme 128GB in the lab soon, and we think it may very well give OCZ something to be concerned about."



 
I think there is a bit of misunderstanding about the write latency. If you take a look at the Samsung 840 Pro review which TweakTown published a few weeks before the Plextor review you will see the decline in write latency is due to the 840 Pro's aggressive garbage collection. With the 840 Pro the process starts right away rather than waiting for an idle or near idle state which is referred to as passive garbage collection. As soon as the aggressive garbage collection is completed the write latency returns to normal. TweakTown mentioned that in their 840 Pro review but not in their Plextor review.

The Plextor MP5 Pro Extreme was designed for professionals and enthusiasts working with heavy workloads, especially write workloads. I guess the magic question is what do you do with your computer?

Thanks for explaining. In the Tweaktown M5 pro review at least, the reviewer pretty much blatantly said the 840 pro isn't even eligible for the "best 128gb" title because of that latency issue. Regardless though, the plextor seems to be certainly in the top 3 SSDs for all around speed (top 2 at 128gb it seems), and it's cheaper, and comes with full kit, and also seems to be a good brand as far as reliability. At this point, I think the only way I will buy a 128gb Samsung pro is if I can find it with a bracket adapter (probably have to buy separate) for same price or cheaper than the Plextor, but in my experiences at least, the m5 pro X is usually up to $30 cheaper when you need the bracket. (which I do)

Right now I can get the 128gb Plextor m5 pro Xtreme for $118 CAD with full kit. Samsung 840 pro I can find for $139, and would have to buy the bracket on top of that.
