Like it or not, the price war in the SSD world involves the incorporation of NAND memory systems that make better use of space, manufacturing costs, etc. This means adding more layers of memory. TLC memories have driven down the prices in the world of SSD. If you can find 240GB drives for fewer than 100 Euros it is largely thanks to these memories that, like everything else, have evolved surprisingly for the best.
Technical performance of the OCZ Trion 100
This new OCZ series will be introduced in its lowest range. With lower prices. It changes quite a bit in relation to other models of the brand. Toshiba puts its new TLC A19 of 19nm memories as the driver, and OCZ puts its expertise in product positioning and engineering.
The Trion 100 is still a SATA model and therefore it is limited by its own interface rather than its own technical performance. It’s not an OCZ advanced model and its objectives are clear. It gives an economic option for all of us who see in an SSD a way to give new life to our computers, either portable or desktop. A SSD drive is largely responsible for having extended the lifespan of many laptop and desktop computers.
Some renowned flash memory manufacturers also produce some of the best SSDs you can find. SanDisk is a good example of this with a varied catalog, and you can also find really attractive prices. The one we present you today is their last high-end creation for SATA interface.
The Sandisk Extreme PRO is a lightweight format disc but it has a powerful controller that incorporates a new system cache to maintain solid performances of the unit over its lifetime. It’s a unit with a rare, easy to manage security for the user and excellent for improving the performance of all kinds of systems, especially laptops.
Samsung expands its storage solutions based on solid state with two new models in M.2 and mSATA formats under the SSD 850 EVO series. This is the best in the SSD market with the new generation of 3D V-NAND memories.
The new SSD 850 EVO is offered in the new M.2 and mSATA formats. Just like the classic 2.5-inch drives, they connect to the SATA interface but with significant improvements in terms of weight, space and energy consumption, which are perfect for laptops, Ultrabooks or convertibles that have this type of connectors.
Intel Corporation, in collaboration with Micron Technology, announced today the availability of its new 3D NAND Flash memory, the highest density flash memory in the world, which will allow bringing SSDs in M.2 format with capacities of up to 3.5 Terabytes and up to 10 TB for SSD in 2.5" format.
This is possible thanks to vertical cell stacking, with 32 layers ("stories") that allow to reach 256 Gb per cell by using MLC or 384 Gb with TLC memory, with the maximum capacity at 3.5 TB for SSDs in M.2 format or 10 TB in the 2.5" format.
This is undoubtedly a breakthrough, since access to solid state drives of larger capacity will help reduce both the price of higher capacity models as well as the models of smaller capacity. Will this be the end of mechanical hard drives?
Having a solid-state drive (SSD) in your computer can be a blessing. A lot more speed than what we get with a conventional hard drive. It may seem silly but you only have to compare how long it takes for the same equipment to load with one or the other.
We’ve told you about them and how we can use them in our computer. Today we want to go a little further and tell you about how to keep it for a long time. They require a little more care, yes, but it’s worth it.
Solid-state vs Hard Disk Drive
Before our advice, let’s do a brief summary about what a solid-state drive offers. Unlike a hard drive, it doesn’t have a head-positioning system that reads different parts of a sector. Its operation is more resembled to that of a pen drive memory. It’s just that: the memory.
In order to achieve this speeds, the new and striking creation from OCZ uses the NVM Express 1.1b technology, which allows to use the PCI Express bus (PCIe 3.0 x4 in this case). This OCZ Z-Drive 6000 NVMe uses a SFF-8639 type connector with hot plug connection.
This way it is possible to achieve reading speeds higher than 3000 MB/s and writing speeds higher than 2000 MB/s. Also, if we talk about performance desktop access, we have an incredible reading 700,000 IOPS and writing 175,000 IOPS. All this with a PCM Sierra Princeton controller with OCZ’s own firmware.
Its capacity goes from 800 GB up to 3,2 TB, although OCZ is expecting to release soon a model with 6,4 TB capacity, that, without surpassing the 2,5 inches, but with a 15 mm thickness, this as thick as we are used to see in conventional SSDs.
However, by now you might have guessed that this product is aimed at the business market, where the size is not a problem, as is its price, which is still unknown and will likely be as astronomical as its speed.
Solid state memories have allowed reducing the sizes of storage devices to unthinkable levels till a few years ago. Currently we have a thick 7mm SSD in SATA format and even in much smaller formats such as the M.2 or mSATA. This makes it possible to provide more capacity and speed to compact devices such as laptops, but this also opens the door to creating external storage units with small sizes and speeds that would be unattainable with mechanical drives.
The new Samsung SSD T1 are a series of external SSD with capacities of 256, 512 and 1TB that are noted for offering speeds up to 450 MB/s via its USB 3.0, practically the theoretical limit that can be achieved with this type of connector.
Samsung has announced the release of the new Solid State Units which will be replacing the 840 series and with the new generation of 3D V-AND memories used for the first time on the 850 PRO. Some chips that can surpass the density limit that the flat NAND architecture is currently facing in conventional flash memories, producing some speed, endurance and energy efficiency improvements.
The 850 EVO SDD’s are available in sizes of 120 GB, 250 GB, 500 GB, 750 GB and 1.000 GB and with prices starting going from $100 up to $500 for the 1TB model.
As SSD endurance test has confirmed the reliability upgrade that the last generation solid state units have experienced, with two of the models tested surviving after standing a massive writing test of over 2 petabytes, an enormous quantity of data that a real person would take dozens of years to complete.
The multiple advantages of having an SSD (consumption, noise, heat emission or performance) derived from the absence of mobile parts are evident, but a few years back there were doubts of the practical endurance of the units in solid state as the standard use for massive information storage. Based on NAND flash memories, the successful writings erode the individual memory cells, both in capacity and performance.
Crucial has introduced its new generation of SSD for the domestic market. The SSD Crucial M600 is one of the greatest innovations with its memory chips manufactured at 16 nanometers with a capacity of 16 GB (128 GB) type MLC, but are capable of changing dynamically to SLC mode when the cells are empty. In such a manner that the capacity of each cell is reduced by half and allows much faster script writing with less consumption. Once the cells are filled it changes back to MLC mode to increase its capacity.
While the SLC cells are filling, the SSD transfers existing data to cells in MLC mode. This is why we will maintain SLC cells (much faster). Naturally, the more space we occupy in SSD, the more the available SLC cells will decrease and we will lose this improvement. However, in order for this to happen we would have to fill almost all the disk. Top speed is achieved when the SSD is below 50% capacity.
