Recommended SSD for pre 2011 MBP

Hello, does anyone know if there has been an update of Hellhammer's recommendation of Intel 320 series SSD's for pre 2011 MBP's ?

OWC backorders

Just a quick word of advice for those considering ordering an OWC SSD -- they seem to be very backordered on a number of drives. I ordered my drive on 12/30 and it was supposed to ship by 1/10. I have live chatted with them a few times and the ETA has been pushed back to 1/18 and then 1/21. Meanwhile I've been unable to get my new Mini set up :( May want to look for other drives if you're considering SSD's and don't want to wait a month!

RAID 1 Question.

If I put a 500gb SSD and a 500gb HDD into a raid one array, will the SSD be limited to the HDD's read and write speed? In other words, will they both need to operate and the same read/write speed, or can the SSD do 500mb/s and the HDD do 100mb/s. This is not for OS X specifically, just wondering.

Buy m4 SSD or wait for m5

Oh man, that has me excited! This year is the year where SSDs are going to hit a very nice bottom in prices!

I'm finally getting around to doing this upgrade. In reading about the m5, it sounds like it has some very strong benefits compared to the m4. On the other hand, the m4 is affordable for me right now and I'm sure the m5 will cost a pretty penny as it starts to roll out. Should I buy the m4 now or wait for the m5?

i have the 256 right now, but i ordered the 512 from crucial because amazon wouldn't ship it to an APO :-( the 256 works fine, no issues :)

i stopped reading at "irregardless" since it is not a word...:eek:

davidlv said:
Did you really mean that "unreliable"?
Irregardless of the corporation's record, I must admit Intel has some very competent engineers, and they use Sandforce controllers in their SSD products.
As far as I know their SSDs have a very good reputation for reliability, maybe the best on the market. How does that make the Sandforce "unreliable"?:confused:
The conclusion I have reached from info in this thread, etc., is that the Sandforce drives vary somewhat depending on the firmware, but in general, due to the way they compress data when writing, is that certain benchmarks that use compressed data show slow results for Sandforce drives. The idea is that for use with a large number of large compressed files, video files etc. a non-Sandforce drive will be faster, but for ordinary use the Sandforce drives are really fast enough. That has been my personal experience (admitted very little), in any case.

Thats the one I have. Been using it for about 18 days and haven't run into any issues. It's a very big step up from my 7200RPM HDD, even at SATA2 speeds. Everything loads quickly, and my MBP sounds a lot quieter unless I'm doing some heavy workload.

I would recommend it.

I just got a 13" uMBP and have 2 SSD drives from other machines that I can install. The choices are:

128 GB Samsung 830 SSD
256 GB Crucial M4 SSD

I don't keep hardly any media on my laptop since I have a home server. More space is always better, but I had read that the 830 may be faster than the M4 though. If true, then speed vs space? Or realistically is the speed the same? Thanks!

The difference in performance is marginal, so I'd install the Crucial SSD as it is the larger of the 2.

Hi,

I'm planning on buying a Samsung 840 Pro for my Macbook Pro, but it's an early 2011 MBP and I've heard that the SATA ports have some compatibility issues. Given the price of the SSDs I wanna be sure that it is going to work properly, so is there any way to know in advance if the SATA is gonna play nice with the SSD ?

Hi all,

I'd like to know the same thing with my mid-2009 MBP 17". Thanks!

I have the 840 pro in my early 2011 MBP and it works flawlessly. It needs to be installed in the main hdd bay to achieve SATA 3 speeds as the optibay is restricted to SATA 2.

Follow this link for the speed increase over the stock HDD.

The 840 pro should would with your MBP but you will only achieve SATA 2 speeds.

Have a look in this thread:

I have a 2011 13" MBP and I don't know which SSD would be better for me:

250GB
http://www.newegg.ca/Product/Product.aspx?Item=N82E16820147189
http://www.newegg.ca/Product/Product.aspx?Item=N82E16820147186

128/120GB
http://www.newegg.ca/Product/Product.aspx?Item=N82E16820147188
http://www.newegg.ca/Product/Product.aspx?Item=N82E16820147192

Or would I really notice the speed increase if I forked over the extra cash for this
http://www.newegg.ca/Product/Product.aspx?Item=N82E16820147193

I didn't want to spend that much money, but I would prefer 25Xgb if I can. I'm fairly certain that most people say the 840 series is better than the M4 in terms of idling power, but if there's another SSD that's cheaper and gives me 25Xgb with no more drain on battery I would certainly be interested in that!

Without - unless you plan on using the drive in a desktop then buy the kit otherwise go with the cheaper one.

First of all, the Samsung 840 uses triple-level cell (TLC) memory vs. the multi-level cell (MLC) memory used for almost all other SSDs. So what is the difference between TLC and MLC? With TLC memory, 3 bits of information (8 possible values) are stored per cell instead of the 2 bits (4 possible values) in MLC memory. This might sound better but it also means that the cells are used more and there is less voltage fault tolerance. In the most simple terms, you can think of cells being "filled" or "emptied" by applying voltage. When 3 bits (8 possible values) of information are stored per cell, the SSD may have to apply voltage to the entire cell multiple times even though just one bit of information is encoded (depending on the bit being changed). The multiple voltage applications to each cell also slows down the write speeds and causes more wear in general.

Performance-wise, the Samsung 840 is actually worse than the previous generation Samsung 830. On the Passmark benchmarks, it is slightly lower than the OCZ Agility 4 which uses asynchronous MLC NAND flash.

Right now, the top three SSDs (best selling and best reviews) on Amazon are the OCZ Vertex 4, Samsung 830, and the Crucial M4. However, all three of these SSDs are cheaper and they perform better than the Samsung 840. Eventually, the TLC NAND should mean that the Samsung 840 will sell for less because less NAND is used. However, it is not worth it right now. To be safe, I would say that you should wait until the drive is at least 10-20% cheaper than the three drives above due to the uncertainty of how it will perform in the long run.

One puzzling thing is that I couldn't find any mean time before failure (MTBF) estimates for the 840, while the MTBF for the 20nm MLC based 840 Pro is 1.5 million hours (lower than the 2 million hours for many 25nm MLC drives). Also, it is interesting that the drives are not 128GB, 256GB, 512GB. There are probably three reasons for this. The TLC NAND manufacturing process has lower yields so they have to "turn off" a portion of the cells to account for this. This is similar to what Nvidia does for their GPUs (16 functional streaming multiprocessors become GTX 580, 14-15 functional streaming multiprocessors become a GTX 570, etc...) Another possibility is that they anticipate that there will be more wear to the TLC NAND so that there is an unused memory bank to replace any dead cells. The third and most likely reason is a combination of the two, i.e. a portion of the turned off cells are nonfunctional due to the new manufacturing process and the remaining portion of the turned off cells are reserved for replacement.

I handle tech purchase decisions for my department and so I bought one Samsung 840 to test for due diligence but won't buy more until they become much cheaper.

Any truth to that? One of the comments to it:

You are quite the little liar trolling for votes. You published this same misleading review for the 250 GB drive only, but you said in a comment there you only had use of the 120 GB drive! To continue, you claim to be some type of IT at a business considering using this drive, when no intelligent IT would even consider a consumer grade drive for business use. Actual people in such business operations only consider the two other memory type SSD platforms due to their more predictable use and their longer MTBF. I suppose you want others here to think Amazon "misplaced" your review here for the 250 GB kit when you have purposely placed it here - again for a 250 GB drive you never had use of, and of the kit you also have obviously never used. You also haven't bothered to mentioned the kit items, since you never had them. Have a wonderful life liar. You can fool all of the people some of the time - but you can't fool everyone all of the time. Abraham Lincoln would have opened you to ridicule for such writing as you've cobbled together here from what you've read and pieced together from the Internet.

As someone who's not even close to an expert on SSDs, I'm not sure to continue to buy the 250gb 840 or to just move along.
