That is not true. I guess you are referring to the infamous OCZ case. The performance is the same as long as the amounts of NANDs is equal. In the OCZ case, OCZ used higher capacity NANDs in some lower-end models, meaning that less channels were populated. For example in the 64GB model, it used to use 16x4GB 32nm NANDs but when OCZ switched to 25nm, they doubled the density and used only eight 8GB NANDs. When less channels are populated, the performance degrades. However, being 25nm or 34nm does not affect this, at least not significantly.

It IS true. OWC's change to 2?nm has also failed to reach the advertised speeds.
 
Do you have a source for that? And a source showing that the amount of NANDs is the same?

I believe Nick is referring to this test from Diglloyd.

Quote from article:

Sustained transfer rate
The OWC Mercury Pro 115GB SSD with the Sandforce controller shows a impaired write speed with pure random data. This appears to have worsened with the move to 25nm flash; prior tests with 34nm devices showed significantly higher write speeds of about 93MB/sec. A 2nd sample showed the same results.

I'm not sure if this is an issue inherent to the 34>25nm change or is just the way it was implemented in the OWC SSD in this test?

It could be similar to the OCZ case. Smaller manufacturing process means that higher capacities can be manufactured so maybe OWC did what OCZ did and doubled the capacity of each NAND, which means there are less channels in use and that affects the performance, especially the write performance.

That was what I was referring to, as well as sporadic reports on forums about this as well. OWC has failed to change their speed listings on their drive despite having made changes which almost makes it a different product. Their drive sizes got smaller, their speed may have decreased, and their price ________???

Perhaps I am overly bitter as I thought so much of their design, company, and end product, and that all of the recent things that I have observed regarding their SSDs have made me question everything.

Well, it's OWC. It wouldn't be the first time they are lying to their customers and it definitely won't be the last.

Snaky69 say's...SATA 111 is not compatible with macbook pro of my model.

No, it IS compatible, it's just wasted speed as the SSD will not be running at it's maximum capacity. If it happens to be cheaper than a SATA II drive, then go right ahead, if not, I'd go to a SATA II just to save some money.

Think of it as buying a honda civic and sticking a ferrari engine in it, it'll never be able to use it to it's full potential because it just wasn't meant to do it.

Thank god it's the mac on the Honda civic end of that damn analogy, for once ;)
 
i Installed my OCZ2 vertex on my MBP 13
Its performace is good, boots up very fast and wakes from sleep very fast
The only thing i noticed is the battery usage, the battery drains very fast, is this normal folks.
after i installed the drive, i didn't made any hardware or tweaks changes
Leave your opinion please

I guess because I am relatively new to Macs I am not familiar with this??? Without a doubt, this issue has changed my perception but I did not know this has happened before?!?

I'm referring to the ongoing issue about the wire thingy in the new 6Gb/s Mercury SSD. Though to be honest, they have been promising the OS X FW updater for months now which IMO is close to a lie nowadays. You can't say that it will be available "shortly" if it has already taken like 6 months and they have no idea about its status.

OWC used to be a good company but their current attitude and business models are something else.
 
Between the OCZ Vertex 3 and the Crucial M4 which of these two drives would benefit from OS TRIM support and which one can go it's entire life without OS TRIM support?

I ask because of the issues with TRIM Enabler and the fact that Crucial drives have been known to degrade in write performance with time.

My past experience with OWC have always been fantastic. I'd been pressing them on this until I decided to go with intel. Everybody that I'd spoken with at OWC at their SSDs have been difficult. And not forthcoming with info. Almost deceptive. I wonder if they're under new management, or ownership, or something. They've left a bad taste in my mouth. Sad. They had been so great to work with up until I started shopping for an SSD.

SandForce controllers are known for their great garbage collection. Vertex 3 should be a safe choice in this matter.

I have used the C300 in a Macbook Pro with the trim hack and it caused beach balls and lags. Without trim enabled there are no problems at all.
Currently you can get the C300 at a good price AND trim the drive periodically by simply downloading an Ubuntu live CD iso, burn it to a cd, connect an ethernet cable to your MBP and boot from then boot from the cd.

Once you select to "try it" you will be running the Ubuntu OS from the cd. Then follow these instructions to trim your SSD.

Regardless of what ssd you choose - last year's 34nm at a good price or current 25nm with benchmark bragging rights - it can be trimmed with little difficulty, and no trim hack to the os need. I am no expert, but I think you'd need to do a heck of a lot of writes to the C300 before you notice the kind of degradation described in that Diglloyd write up.

Thanks for answering

Thanks for this, looks simple enough. Problem is, i'm kinda lazy. I just want to dump the SSD in there and forget about it...not have to worry about maintenance for years at least.

If i go Crucial as opposed to the OCZ it seems i'll have to take on a hands-on approach in order to keep things moving smoothly no? or is this characteristic of any SSD out there?
