Which SSD is cheap, lives for the longest time, and doesn’t drop the speed after just running on your machine for a few weeks? Many SSD’s are really overpriced and do not offer what is to be expected of them. There are simply just some brands that dominate this market more than others. And if haven’t been researching the market, it can be very hard to find the best SSD in 2015. Which is why we decided that this task had to be easier for users. So, therefore, we came up with Best SSD 2021, where we do our best to make sure that you can find the SSD that fits you.
In this article, we will announce the best SSD in 2021. If you are still wondering if you should pick up an SSD, then worry no longer. The SSD is dropping in price in 2021, and they constantly get improved. The first SSD was released in 1976, but they first started to get a lot of attention when Samsung started entering the business in the late 2000s. Now every new gamer computer almost has an SSD. And I can definitely recommend you to pick one up. It has personally made my life in front of the computer a lot easier. What really makes me fall in love with SSD’s is the insane speed that you can load up Windows 8 or 7. And programs such as Adobe Photoshop will run much faster and smoother.
The Solid State Drive is converting to the standard storage in a good number of informatics segments special in mobile devices (tablets, laptops, 2 in 1 and Ultrabook’s). the extension for portables of great consumption and desktop is only a matter of time to increase their formats uses, and improve its technology and a constant price drop happens.
You know its advantages over other solutions such as hard disks, drives starting with its lower consumption, vibration, noise and heat emission by the absence of moving parts, along with much higher performance. Today we review five General aspects to be considered in the purchase of an SSD.
Here are the Best SSD Prime Day Sale 2021:
The fall in the price of memories NAND flash are based SSD, have led to a price collapse in the final product. If in 2010 the average price a little bit more than 0,3 dollars per GB.
SSD has never been cheaper but the price is an aspect (perhaps the only) where hard disks have a great advantage.
As in hard disks, purchasing a larger SSD usually offer more value for money. As an example of a series that dominate sales (Samsung EVO 850), buy the 120 GB model supposes paying 0.61 per GB while the model with 500 Gbytes of capacity, lowers the cost to 0.36 dollars per GB.
Search for the balance between capacity and price. To replace the hard disk of a laptop a 250-Gbyte SSD should be sufficient for most users. Desktops with 1, 2 or 4 Tbytes HDD replacement by SSD assumes wasteful spending. The best choice – for the moment – is to combine both. 250-Gbyte SSD recommended for installation of the operating system and major applications and drives for mass storage and backup is an ideal combination for the current market because it guarantees performance and ability to price.
The most popular SSD are those that use a standard 2.5-inch format (same as hard disks) but beware its height because not all services for all laptops. There are 9.5 mm and 7 mm. Make sure that you buy the correct size hard disk for your laptop will be able to fit your laptop.
Para ordenadores de sobremesa teres no problem whit the thickness. You can use them as they come even though the ideal is to buy an adapter to 3.5 inches for the best mounting on a PC Tower.
In recent times have appeared other types of SSD, among which we can highlight the mSATA and M.2. They are specially intended for the market of portable although some motherboards for PC from latest generation are starting to include them. With a size of memory in the case of mSATA module and allow even smaller in the case of M.2 decrease the thickness, weight, and consumption from the same noticeably against the standard 2.5-inch SSD. See if your laptop supports them prior to purchase. They are more expensive but you rate your purchase.
Attention also to the bus connection. If units of 2.5 inches are connected to the SATA interface (do not buy anything that does not support SATA-III – 6 Gbps), some M.2 models are connected to the PCIe bus with a substantial increase in performance. Special mention to the development PC on PCIe. Especially aimed at professional workstations, is a format similar to a dedicated graphics card, which uses native interface PCI-e to fire its performance up to a theoretical maximum reaching five-fold of the solid-state drives connected to SATA. For now, its price is prohibitive for large consumption but there goes the future of storage on PC.
It is one of the main advantages of SSD. When you replace a hard drive you’ll see as your laptop “comes to life” during startup, opening applications, file transfer and overall performance of the machine. Are equally remarkable as a result on a PC by combining SSD HDD.
However, not all SSD offers the same performance, derived from the used memories and especially of its driver. Users who buy an SSD currently should not settle for a unit that does not reach the 500 Mbytes per second in a SATA both reading and writing data transfer speeds. There are very cheap SSD that reduce this figure, especially in writing. Avoid them, don’t worth it.
There is an important difference between the way that handles an HDD and SSD data. An SSD write data in chunks called “pages”. A page group is called a block and to write new data to an occupied block, the entire block has to be deleted first. To avoid loss of data, all the information that exists on the block first should be moved elsewhere until the block can be erased. Once data is moved and the block is cleared, only then they can be written
This process is almost instantaneous but requires free space so that it works correctly. If there is not enough free space the process loses efficiency and slows down. We discussed this technical section because it affects the ability when we carry out the purchase of an SSD. to achieve their maximum efficiency should leave approximately 20 percent of the free unit. That is why we recommend the purchase of a unit of at least 250 Gbytes.
For the short term future, SSD capacity will match and even exceed the hard discs. Samsung will offer the 850 EVO with 2 Tbytes; companies such as Fixstars already have for sale 6 Tbytes models; SanDisk will commercialize 8 Tbytes units in 2016 and Intel from the hand of Micron offer next year models with 10 Tbytes.
Resistance and longevity
Despite their mechanical components, hard disks are still “standard and signal” for resistance units of storage, and hence its mass use on servers and 24/7 data centers where premium reliability above all. In addition, they require tests and certifications that can last for months and therefore the entry of SSD has been up to now very shy.
Unlike hard drives, SSD has no moving parts that give them a great advantage in terms of the impossibility of mechanical failure. On the other hand, SSD is more prone to power failures While the unit is in operation, causing data corruption or even total failure of the device. In addition, SSD memory blocks have a limited number of write operations.
Fortunately, new generations have improved a lot in reliability. All SSD include free additional memory cells when others fail to not lose capacity, reallocating damaged sectors. Manufacturers offer 3 or 5-year warranty and the official average life of an SSD is estimated between 5-7 years.
Latest stress tests have confirmed this increase in reliability with any series of units surviving after one support massive test of writing over 2 petabytes. A huge amount of data that a user in real conditions (normal use) would take dozens of years to complete.
