What's the difference between mSATA boot and SSD?

Msata is an interface. SSD is a solid state hard diskSolid state storage technology, referred to as SSD. can generally be divided into two types, one is the SSD: flash memory using FLASH MEMORY as the storage medium which is usually based on the common SSD, U disk is often used, digital cameras and other electronic memory and some ATA, SCSI, FC connection Flash Disk, referred to as flash disk.The SSD interface can be msata, SATA, PATA, USB, eSATA... The speed of contrast is meaningless. Whether it is Caching (understood to add a super large memory) or Boot (Understanding RAID), the fast startup is pure SSD. If the program on HDD is started fast, caching will be better.

What's the SSD of a laptop computer? Its role?

SSD is a solid state hard disk. Generally speaking, the speed of solid state hard disk is faster than that of a normal mechanical hard disk.It's too professional to say. For example, if a computer starts normally, it will take 40 seconds. If your computer has solid state hard disk and install the system in solid state drive, it will start more than ten seconds. If you put the game into a solid state hard disk, the game is getting into the game greatly.

Is the SSD hard disk partitioned or not partitioned well?

The partition has no negative impact on SSD life. If there is a negative impact on the design of the SSD vendor, there is a problem. For instance。 For example, a 200G's mechanical hard disk and a 200G solid state hard disk are divided into 2 100G partitions: C and D disk. And then have to write C, D disk without. In this case, for mechanical hard disks, the physical space of 100G is wasted, and nothing has been written in [1]. But it does not have any effect on the solid state disk, because the firmware (Firmware) can dynamically set the logical address of 0~100G (LBA logical, block address) mapped to the entire 200+G physical space (200+G instead of 200G, because the real capacity of SSD is greater than the nominal capacity, because of the need of extra space to move data convenient background defragmentation). So it's not like a mechanical hard disk that writes only the physical medium of 100G, causing this 100G to hang out first. More counterintuitive is to write only 100G, while the other 100G doesn't write at all, but it will extend the life of SSD (life is defined as the total amount of data written before SSD hangs up). There is a concept of cold and hot data in the storage field (cold and hot data, which is not very clear how the Chinese literature is generally translated). In the above example, the 100G logical address that is written without stopping is hot LBA, and the logical address of 100G belongs to cold LBA. Each SSD vendor has more or less in the firmware, or a good or effective algorithm to distinguish hot/cold data and treat it differently. The use of heat and cold is the premise of the treatment of cold and hot data. The WAF (write amplification factor) is smaller than the complete probability of writing any LBA, so the life expectancy is longer. Of course, if there is no ability to distinguish between cold and hot data in SSD, and the user's condition has obvious cold / hot data, it will have a negative impact on life expectancy. But it doesn't have anything to do with your partitions. The first 512 byte data block (logical block) of your D disk is partitioned. Its LBA is 100G/512 + 1, no partition, or 100G/512 + 1, which is not affected. In the end, it's all nonsense. For ordinary users, do not overestimate their ability to make data. You basically didn't give a piece of SSD could produce enough flash (PE) SSD NAND flash times lead to aging and hang up. There was a very interesting report on Flash Memory Summit last year. The data of an enterprise - level storage server manufacturer tracking SSD usage in a product is that 97% enterprise level SSD users write less than 0.2 PE[2] a day. As for ordinary users, only less.  Bug or SSD firmware in a flash chip is defective when you slip through the inspection or the room humidity is too high resulting in a circuit out of the original problem, cause probability SSD hang possible than the probability of SSD is written up much. The conclusion is that you want to partition the partition and don't worry about the life span. The more general conclusion is how to use it, pay more attention to speed, and pay less attention to life. [1] now Shingle technology has been widely applied to mechanical hard disk, so this example is only applicable to some mechanical hard disk and previous mechanical hard disk. [2] here I started the wrong conclusion, then check the original report "All-Flash Arrays Require Scalable CostEfficient Software-Defined Architectures" by Shachar Fienblit, found that 97% enterprise users a day to a total capacity of 0.15*SSD data, however, this is written before the data write amplification, amplification is about on the day the SSD write it again. But the cheapest enterprise SSD is generally designed by writing the entire SSD 1 days before writing and enlarging, so the amount of the data is still very small. The consumption level SSD can't find data, but it should be similar.

i have a computer that uses ddr2 memory will this solid state drive work with?

The memory you have in your computer has no bearing on whether this SATA SSD will work in your computer. As long as your computer has SATA power cable and ports on the motherboard it should work. 

What does the ddr3 dram cache buffer stand for?

The type of RAM you have does not affect the hard drive. It will work fine with your system. 

How to calculate the daily write of a hard disk (DWPD)

How to calculate the daily write of a hard disk (DWPD)Hard disk write every day (DWPD) calculation so that we can use TBW disk according to the specification, used to specify the TBW JEDEC [1] work load calculation, during the warranty period (or different years period) the number of users every day can be written to the hard disk storage capacity.Hard disk writes every day =TBW (TB) * 1000 of solid state hard disk365 days * years * solid-state disk user capacity (GB)The warranty period is 5 years 1.8TB DC400 SSD, is calculated asHard disk writes every day =1432TB * 1000365 days * 5 * 1800GB= 0.43 or 43% per day user capacity (that is, 774GB)Reference resourcesJESD219: solid state hard disk (SSD) durability work load, JEDEC Committee . These client and enterprise workload represent a standard. The industry uses this standard to grade their SSDs and get their rated TBW supported by SSDs. Note: your workload can be different. Because the unique WAF you use, over time, the rated TBW specification may be higher or lower than your workload.

Which three kinds of particles of solid state hard disk, TLC, MLC, SLC, which is better and more sta

SLC has better life, faster, and most expensive for enterprise hard drivesMCL second life is twice as long as TLC (Theory) a little faster than TLCTLC finally came out more controversial but the price was quite cheap (at least when I bought it, 120G was hundreds cheaper than MLC).But now the price has risen to almost no cost to the MLC.The current situation suggests that the stability of the MLC's solid state hard disk can be almost used in the process of shaking and even wrestling.But mechanical hard drives can't be damaged that way.

Good mechanical hard disk or solid hard disk?

Now there are 3 kinds of hard disks on the market, the mechanical hard disk: the traditional hard disk, the advantage is the priceSolid state hard disk: the new generation of hard disk, the advantage is that the speed of reading and writing is fast, the disadvantage is the higher priceHybrid hard disk: a mechanical and solid mixture, a bit like RAID, and it's not a lot of people now.Because SSD prices so many people will choose to buy a small solid-state drives, such as 64G only install the system, and then with a mechanical hard disk storage data, if choose the SSD of course better, this is not only the system speed, and operation and call the other disc the data will be relatively fast

What are SSD and HDD, what's the difference?

SSD is a solid state hard disk HDD that is now the mainstream mechanical hard disk.The difference between the two words, the working principle of different SSD which is composed of flash memory read speed of particles to more quickly than HDD but the service life of the SSD not HDD him for so long reading times is limited and is currently SSD high price now or in group HDD disk array more cost-effective

Can u use it with a smartphone?

Yes. If you're an electrical engineer you can open the phone and solder a USB port onto your phone to accept this giant monstrosity of a hard drive. That or be simsible and get an sd card, you know. The part that actually is used by the phone for storage. Good luck doc brown, o I KNOW you cameo it! 

Can i install this into a sony vaio sve17135cxb laptop, replacing my current hard drive?

Yes you could but you’ll lose your windows install. 

How many years guarantee has this item?

This SSD drive has a three year warranty. 

How do I load windows onto this drive after installing it into a thinkpad?

If you use a flash drive or CD to install windows you can choose what drive to install windows on during the set-up process 

What is the actual available space to user on the 120gb and 240gb ssd models ?

The 120GB SSD drive would should up as about 110GB and the 240GB would be 220GB.
