On my next visit to the States I need to bring back some new SSD's for one of my workstations. Stumbled across this website when looking at reviews to decide if I should get the 850 pro or not.
I recently built a new computer and bought the 840 EVO; In a word, they are incredible. Highly recommend them. I have two 500 gigs running in raid 0. Windows 7, from boot logo to desktop, loads in 10 seconds! Actually 10.38 seconds... Almost Every program that loads is instant. Best part - No moving parts... so its quiet... You never realize how much sound a hard drive makes until you get one of these.
From my research: There is not much "noticeable" performance difference between the standard and the pro. Of course this depends on what you are doing with it. The price compared to the standard drive is almost double. Plus the 840 Pro seems to have a higher failure rate. Check out the reviews on 840's vs the 840 pro on New Egg. It will give you a good idea on performance and issues. From what I am reading the new 850 standard has comparable specs to the 840 pro.
Question> did u see much of a difference with NT7 reloading a chart before and after SSD Im thinking of upgrading just for this reason. I have a very fast pc for non ssd
The 840 EVO is supposed to be even more advanced than Pro. The lower ranking for the read and write are basically due to a software bug in performance shifting logic. That has been taken care of with the new release of the performance software, as noted in earlier posts. The EVO versions are a bunch cheaper for minor performance differences with Pro version that are not normally noticeable. The 840 EVO is a great value.
By the way, I assume you are comparing the 850 Pro and 850 EVO since the 850 Pro is a generation ahead of the 840 EVO in terms of performance (nearly 50% faster on everything, random and sequential read/write).
The main reason for the price difference between the Pro and EVO is that the 850 Pro can endure 2x as many write cycles than the 850 EVO and has a 33% longer MTBF rating (Telcordia reliability test). Basically, it is more durable. I've seen people use the 840/850 Pro in data center environments where you're expected to switch it on and leave it alone for 5 years, but never the 840/850 EVO. That's something that isn't measured on the benchmarking site mentioned above.
My recommendation would depend on the use case:
- For a workstation, the Intel 730 was at $109 during Black Friday and that would've been my first choice. But any value-oriented SSD would probably work, e.g. Samsung 850 EVO, Crucial M550 or MX100, whatever's cheapest.
- For a 24/7 and fault-intolerant environment, and maybe if a RMA is pain-in-the-neck e.g. you're out of the country, I would recommend at least the Intel 730 or 850 Pro.
- For a write-intensive environment (e.g. data), I would recommend at the least the DC S3700, but this is unlikely for most of us, because use cases in finance aren't write-intensive, rather, they are write-once-read-many.
I have a bunch of 840 pros in servers in Chicago, not a single failure ever. On the other hand, every single OCZ and Crucial has failed. They were all replaced with 840 pros, the last being only a few days ago
