i have cmbp 2012 high end model and there is a sale on SanDisk Ultra plus 256gb SSD at price of samsung 840 pro 128gb, is it a good drive? wait or buy?
I'm not able to comment on the SanDisk, but I can vouch for the Samsung and say that it's a great drive. I have 4 of them in various computers and haven't had any issues with them.i have cmbp 2012 high end model and there is a sale on SanDisk Ultra plus 256gb SSD at price of samsung 840 pro 128gb, is it a good drive? wait or buy?
i checked your link and compared sandisk with samsung 840 256 ,samsung is a little better in write speed in all write tests and power consumption.Did you check Tom's?
Here it is with the other top ten 256GB drives. Here's the full list: http://www.tomshardware.com/charts/ssd-charts-2012/AS-SSD-4K-Q64-Random-Read,2786.html
but if you check the sandisk ultra plus web page there is no 480/500/512 gb optionit should do fine, its a good controller, however that capacity is off, to function properly that controller needs at least 480gb
I dunno which SSD drives are "best" for that price but yes, the benchmarks offered there are very useful in determining real-world performance. Primarily because there are so many different kinds benchmarks offered. Find the one or two stats which relate or seem to relate to the real-world use you wanna know about.i checked your link and compared sandisk with samsung 840 256 ,samsung is a little better in write speed in all write tests and power consumption.
sandisk scored around 20000 IO/s in IOMeter 4K Random Reads Benchmark
ver. 2006.07.27 , samsung scored 73000 IO/s
what you think?, are these numbers really affect total performance (coding,photoshop,illustrator,HD movies,gaming,long usage)?
after research i think this drive is slow and old, i will wait for getting 500 gb ssd at reasonable price.From what I have read, the Sandisk Ultra Plus is the 'value' drive in the Sandisk range of SSDs and uses the Marvell SS889175 controller.
Then there is the the Sandisk Extreme (old model with Sandforce controller).
The new 'performance' model is the Sandisk Extreme II using the Marvell 88SS9187 controller (same controller as Crucial M500).
You might have to search for some application based benchmarks to see if it's worth spending the extra money.
Which drive are you referring to?after research i think this drive is slow and old
If you are waiting for 768MB/s SATA-3, you are in for a long wait.i will wait for getting 500 gb ssd at reasonable price.
sata 3 offers 768MB/s and i want drive at this speed,is it available?
I'm referring to sandisk ultra plus.Which drive are you referring to?
If you are waiting for 768MB/s SATA-3, you are in for a long wait.
SATA-3 is 6Gb/s or 6000 Mb/s, but that is the raw bitrate including overhead, so you will never get a SATA-3 drive that can transfer your data at that speed - sata-io.org mention a "theoretical" maximum throughput of ~600 MB/s.
If you want a fast SATA-3 SSD with a good reputation for reliability, then get a Samsung 840 Pro.
Or, if you want something faster in a MBP, then you will need to wait for new rMBP models which are likely to include pci-e flash storage.
Most people find that a slightly slower SSD makes no difference that they could ever notice without benchmarking. I'm probably going to get the Crucial M500, but most of the drives mentioned in this thread should be a big improvement over any spinning disk.
The Samsung 840 (non pro) appears to be a popular choice. I'd prefer to let others beta test the TLC NAND drives like the 840, but I'm probably being overly cautious.
