SanDisk SSD Ultra Plus, based on Marvell SS889175 6Gbps SATA/NAND controller.
SanDisk Extreme SSD (SandForce SF-2881)the ultra plus is a little faster than the Crucial M4
I have the 64MB Crucial M4 and I am very happy, considering that it is much slower than the same in 128MB and 256MB

Well I think I have it clear, I will opt for the Marvell controller and within this Sandisk Ultra Plus or failing that Crucial M4 all this in 128 Gb.
Thanks for your advice

The Samsung 840 pro 128gb is a bit more expensive but also performs a bit more, it is also an option.

It probably has a bit more performance, but in an APP store near my house there is a price difference right now of 44€ compared to the Sandisk ultra Plus of 128Gb, I think it does not compensate for a bit more performance for that difference. Apart from this, the leap I am going to make in the equipment will be beastly since my operating system is installed on a WD Caviar Blue HDD of 500 Gb at 7,200 Rv of 16 Mb of buffer.
Taking advantage of the thread as you can see this option in terms of performance reliability and price compared to the Sandisk Ultra Plus:
- **Sandisk Ultra Plus 128 Gb SDD 91.80€
- PLEXTOR PX-128M5S M5S SSD 128GB 2.5 SATA3 105,10 €**

They also spoke very well of the plextor, I'm not sure if it was that particular model, if it is I would go for it.

it's not worth it, it doesn't have trim and it consumes a lot
buy the sandisk or the crucial

no tiene trim
:( that's weird... it's worth saving and spending on one with good capacity and performance. At least I don't regret spending the money in the slightest.

Can you explain what exactly trim is, and regarding consumption, generally SSDs usually consume the same amount, right?

Can you explain exactly what TRIM is?
I asked the guru and he said this:
! In computing, a TRIM command allows an operating system to communicate to a solid-state drive (SSD) which data blocks are no longer in use, such as data left behind when files are deleted. An OS operation like a delete usually only marks the involved blocks as unused. TRIM allows the OS to pass that information to the SSD's controller, which would otherwise not know which blocks it can delete.
! The purpose of the instruction is to maintain the speed of the SSD throughout its entire lifespan, avoiding the slowdown that early models suffered when they reached writing to all cells at least once.1
! Although there were already tools to reset some SSD models to their original state, they could not be considered optimization tools since they needed to erase all the data on the drive.
! The initial cause of the problem is that SSDs do not know which blocks are actually in use and which are free. SSDs do not understand the structure of the file system used by the computer's operating system and cannot access its list of unused clusters. This causes problems in two places:
! SSDs can write 4KiB blocks, but due to hardware limitations, they must erase larger blocks (e.g., 128KiB-512KiB). Because the drive cannot know which of the 4KiB blocks is still in use if it has been written before, each write requires a larger read-erase-modify-write cycle, assuming that no additional free blocks are available on the SSD (e.g., after all blocks have been marked as at least partially written). The term for this phenomenon is write amplification.2 3 4
! Wear levelling allows a drive to re-arrange its data so that writes are not confined to one corner of the flash chip. Flash cells only tolerate a limited number of writes before failing, so some SSDs move data around to distribute the write load more evenly across all blocks in the drive. Because the drive does not know which blocks are actually in use by the file system, each block of data written by the drive requires an additional write due to the displaced block.
! The specifications for the TRIM command5 are being standardized as part of the ATA interface standard, led by the T13 Technical Committee of the International Committee for Information Technology Standards.6Source: TRIM - Wikipedia, the free encyclopedia

Haha, needless to say. …., we'll look it up in the wikiespavilaburros

I seem to have read somewhere that you could save yourself the TRIM by leaving the PC on in the BIOS overnight with the garbage collector XD I'm saying this from memory and I'm not sure if the terms I mentioned were exactly these… :ugly:
