Ilaa dhawaan, darawalada SSD aad ayey uga qaali san yihin Hard Disk-yada oo isticmaaleyaal badan ayaa iska ilaalin jiray in ay ku cusboonaysiiyaan Hard Disk-gooda SSD Drive-ka. Si kastaba ha ahaatee, sida tignoolajiyada ^(How)SSD ay u horumartay, qiimuhu hoos buu u dhacay oo hadda waxaan haysanaa darawalo kaydin deeqsinimo leh iyo heerar kala wareejin ah oo la ixtiraamo, qiimo jaban. Kingston SSDNow UV400 waa mid ka mid ah doorashooyinka miisaaniyada ugu caansan ee aad ka heli karto isticmaaleyaal badan ayaa u janjeera inay ka iibsadaan noocyo ka qaalisan. Caannimadiisu si fiican ma u qalantaa? Intee ayuu^(How) degdeg badan yahay Akhri faallooyinkan si aad u ogaato jawaabaha su'aalahan:

Unboxing iyo hardware qeexida

Marka ay timaado khibrada unboxing, SSDs waa qaar ka mid ah aaladaha caajiska badan ee aad iibsan karto. Dhamaadka, ma jiraan wax cajiib ah oo ku saabsan iyaga: qalabkooda yar yar ee keena kaydinta degdega ah. Hoos waxaad arki kartaa sida fudud ee baakadaha Kingston SSDNow UV400 .

Markaad gooyso baakadaha, waxa kaliya ee aad ka heli doonto waa SSD drive. Ma jiro buug-gacmeed ama saxan wadata darawallo. Daboolka wuxuu u eg yahay oo wuxuu dareemayaa xoogaa jilicsan, markaa waxaa fiican inaad fiiro gaar ah u yeelato markaad ku rakibayso darawalka gudaha kombiyuutarkaaga.

Dhanka dambe ee wadista, waxaad arki doontaa SATA^{(SATA Rev)} Rev. 3.0 iyo koronto, iyo sidoo kale qaar ka mid ah macluumaadka aqoonsiga ee ku saabsan darawalkaaga 2.5 " SSD . Markaad gacantaada gasho, waxaad ogaan doontaa in darawalkani uu aad u fudud yahay, culeyskiisuna yahay 2.01 ounces ama 57 garaam.

Awoodda la xayaysiiyay ee wadista aan tijaabinay waa 480 GB. Si kastaba ha ahaatee, Windows ayaa sheegay in 447 GB ay diyaar u yihiin in lagu qoro xogta. Kingston SSDNow UV waxa kale oo lagu heli karaa awoodo kale sida: 120GB, 240GB iyo 960GB.

Kingston SSDNow UV400 waxa ay^{(Kingston SSDNow UV400)} xayaysiisaa qiimaha kala wareejinta ilaa 550MB/s ee xogta akhriska iyo 500MB/s ee qorista xogta. Si loo siiyo xoogaa aragti ah, waa kuwan sicirka wareejinta ee lagu yaboohay darawalada ku tartamaya isla qiimaha kala duwan:

• ADATA Premier SP550 - 560 MB/s ee xogta akhriska iyo 510 MB/s ee qoraalka xogta.
• Muhiimadda BX200^(BX200) - 540 MB/s ee xogta akhriska iyo 490 MB/s ee qoraalka xogta.

Xakamaynta loo isticmaalo Kingston SSDNow UV400 waa Marvell 88SS1074 , halka nooca NAND uu yahay ^(NAND)TLC (wax badan oo ku saabsan qaybta xigta ee dib u eegistan).

Isticmaalka korontada ee la xayaysiiyay waa 0.672W marka darawalku aanu shaqaynayn iyo 0.693W ee xaaladaha isticmaalka celceliska. Heerkulka hawlgalku wuxuu noqon karaa 32°F ilaa 158°F ama 0°C ilaa 70°C

TLC NAND iyo waxa ay adiga kugu tahay

Marka ay timaado darawallada SSD , mid ka mid ah tilmaamaha ugu muhiimsan waa nooca xusuusta NAND ee loo isticmaalo. Tani waa nooc ka mid ah kaydinta aan kacsanayn oo aan u baahnayn awood lagu hayo xogta. Waxay leedahay tiro xaddidan oo wareegyo qoraal ah. Waxa loo isticmaalaa in lagu kaydiyo dhammaan xogta ku jirta darawalkaaga SSD . Waxaa jira saddex nooc oo ah xusuusta NAND flash loo isticmaalo SSD -yada casriga ah: SLC (ka ugu qaalisan iyo kan ugu cimri dheer), MLC iyo TLC .

TLC NAND waa ka ugu jaban saddexdaas hadafkeeduna waxa uu ahaa in la dhimo kharashka xoogaa yar iyo in la kordhiyo awoodda ugu sarreysa ee chip si memory-ga uu ugula tartamo qiimaha hard disk-yada caadiga ah. Dhimista qiimaha TLC NAND waxaa lagu sameeyay kharashka dulqaadka. Sida isbarbardhigga dhammaystiran uu muujiyay^{(thorough comparison has shown)} , TLC NAND waxaa la filayaa inay sii jirto wax ka yar noocyada kale ee NAND . Taasi waa sababta aan loogu talinayn goobaha ganacsiga iyo isticmaalayaasha u baahan kaydin aad u waara oo si weyn loo isticmaalo, si joogto ah

Kingston hadda waxa uu u isticmaalayaa Toshiba 's 15nm TLC NAND UV400 SSD^{(UV400 SSD)} . Maaddaama Kingston uusan ahayn soo-saare semiconductor, helitaankuna uu yahay mid is-beddelaya, waxa laga yaabaa inay u baahdaan inay NAND Flash ka helaan alaab-qeybiyeyaal kale mar kasta oo ay jiraan isbeddello jiil. Si kastaba ha ahaatee, UV400 had iyo jeer waxay la kulmi doontaa faahfaahinta liiska iyada oo aan loo eegin qaybaha gudaha.

Waxqabadka marka la barbar dhigo

Si loo qiimeeyo waxqabadka darawalkan SSD , waxaanu ku socodsiinay dhawr bartilmaameed oo nidaamka tijaabada ah:

• Taxanaha: Taxane^(Sequential) ( Block Size=1MiB ) Wax ku Read/Write hal dun
• 4K: Random 4KiB Ku qor^{(Read Write)} hal saf iyo dun

Hoos waxaad ka arki kartaa natiijooyinka aan ku helnay nidaamka imtixaankeena. Guud ahaan way wanaagsan yihiin, laakiin uma badna sida lagu xayaysiiyay tilmaamaha rasmiga ah. Si kastaba ha ahaatee, marka la barbar dhigo Hard Disk-dhaqameedka, Kingston SSDNow UV400 aad buu u dheereeyaa.

Marka xigta, waxaanu isticmaalnay HD Tune si aanu u cabbirno ugu yaraan, ugu badnaan iyo celceliska xawaaraha wax-akhriska ee MB/sec . Halbeeggani waxa kale oo uu ina siinayaa celceliska gelitaanka wakhtiga millise seconds (ms) iyo sidoo kale heerka dilaaca (xawaaraha ugu sarreeya ee xogta lagu wareejin karo interface-ka wadista nidaamka hawlgalka. metric kale oo faa'iido leh oo ay wadaagaan HD Tune waa Isticmaalka CPU wuxuu muujinayaa (intee in le'eg ee processor-ka (in%) nidaamku u baahan yahay inuu akhriyo xogta SSD -ga ) Waxaad arki kartaa natiijooyinka aan helnay hoos. Mar labaad^(Again) , way ixtiraamaan laakiin hubaal way ka hooseeyaan waxa Kingston xayeysiiyo.

Halka qiimaha la mid ah waxaad ka heli kartaa darawallada kuwaas oo wax yar ka dheereeya Kingston SSDNow UV400 . Si kastaba ha ahaatee, kala duwanaanshiyaha ayaa aad u yar.

Reviewing the Kingston SSDNow UV400 - Generous SSD storage on a budget!

One bullet-proof way to ѕpeed up an aging computer is to replace itѕ traditional hard disk with an SSD drive. Until recently, SSD drives were а lot more expеnsive than hard disks and many users avoided upgrading theіr hard disk with an ЅSD drive. However, as SSD technolоgy has evolved, prices went down and now we have drives with generous storage and respectable transfer rates, at an affordable рrice. Kingston SSDNow UV400 is one of the most popular budget choices уou can find and many users tend to buy it over more expensive models. Is its pоpularity well deѕerved? How fast is it? Read this rеview to learn the answers to theѕe questions:

Unboxing and hardware specifications

When it comes to the unboxing experience, SSDs are some of the most boring devices you can purchase. In the end, there's nothing fancy about them: their just small devices that deliver fast storage. Below you can see how simple is the packaging for Kingston SSDNow UV400.

Once you cut the packaging, all you will find is the SSD drive. There's no manual or disc with drivers. The casing looks and feels a bit fragile, so it is best that you pay attention when mounting the drive inside your computer.

On the back of the drive, you will see the SATA Rev. 3.0 and power connectors, as well as some identification information about your 2.5" SSD drive. When you take it into your hand, you will notice that this drive is very light, weighing only 2.01 ounces or 57 grams.

The advertised capacity of the drive that we tested is 480 GB. However, Windows reported that 447 GB were available for writing data on it. Kingston SSDNow UV is available also in other capacities like: 120GB, 240GB and 960GB.

Kingston SSDNow UV400 advertises transfer rates of up to 550MB/s for reading data and 500MB/s for writing data. To give a bit of perspective, here are the transfer rates that are promised by competing drives in the same price range:

• ADATA Premier SP550 - 560 MB/s for reading data and 510 MB/s for writing data.
• Crucial BX200 - 540 MB/s for reading data and 490 MB/s for writing data.

The controller used on the Kingston SSDNow UV400 is Marvell 88SS1074, while the NAND type is TLC (more on that in the next section of this review).

The advertised power consumption is 0.672W when the drive is idle and 0.693W under average usage conditions. The operating temperature can be anything from 32°F to 158°F or 0°C to 70°C

TLC NAND and what it means for you

When it comes to SSD drives, one of the most important specifications is the type of NAND flash memory that it is used. This is a type of non-volatile storage that does not require power to retain data. It has a finite number of write cycles. It's used to store all the data on your SSD drive. There are three types of NAND flash memory used in modern SSD drives: SLC (the most expensive and the most durable), MLC and TLC.

TLC NAND is the cheapest of the three and its goal has been to reduce the cost per bit and increase maximum chip capacity so that flash memory can compete in terms of price with traditional hard disks. Cutting down the cost in TLC NAND was done at the expense of endurance. As this thorough comparison has shown , TLC NAND is expected to last less than the other types of NAND. That's why it is not recommended for business environments and users who need very durable storage that's used heavily, on a regular basis

Kingston is currently using Toshiba's 15nm TLC NAND in its UV400 SSD. As Kingston is not a semiconductor manufacturer and availability is ever-changing, they may need to source NAND Flash from other suppliers whenever there are generational changes. However, the UV400 will always meet the specs listed regardless of the internal components.

Performance in benchmarks

In order to evaluate the performance of this SSD drive, we ran a couple of benchmarks on the following test system:

• Processor: Intel Core i5-6600T
• Motherboard: ASUS Z170 Pro Gaming
• Memory: HyperX FURY Black 16GB, DDR4 at 2133MHz
• Graphics card: GIGABYTE GeForce GTX 950 OC WindForce 2X, 2GB GDDR5, 128-bit
• Operating system: Windows 10 with Anniversary Update

We started by running CrystalDiskMark, which runs several tests for reading and writing data, both sequentially as well as randomly:

• Seq Q32T1: Sequential (Block Size=128KiB) Read/Write with multiple queues and threads
• 4K Q32T1: Random 4KiB Read/Write with multiple queues and threads
• Seq: Sequential (Block Size=1MiB) Read/Write with a single thread
• 4K: Random 4KiB Read Write with a single queue and thread

Below you can see the results we got on our test system. They are generally good, but not as great as advertised in the official specifications. However, when compared to a traditional hard disk, Kingston SSDNow UV400 is a lot faster.

Next, we used HD Tune to measure the minimum, maximum and average read speed in MB/sec. This benchmark also gives us the average access time in milliseconds (ms) as well as the burst rate (the highest speed at which data can be transferred from the drive interface to the operating system. Another useful metric that is shared by HD Tune is the CPU usage shows (how much processor time (in %) the system needs to read data from the SSD). You can see the results we obtained below. Again, they are respectable but definitely lower than what Kingston advertises.

At a similar price point you may find drives which are slightly faster than Kingston SSDNow UV400. However, the differences are rather small.

Pros and cons

Here are the pluses we identified for Kingston SSDNow UV400:

• The price - this SSD drive is very affordable, making it easy for budget users to replace their traditional hard drives
• The performance you get for the price is very respectable

There are also a few downsides to consider:

• This SSD drive uses TLC NAND, which makes it less durable than SSDs with other types of NAND flash memory
• It is not recommended for business environments and users who need very durable storage

Verdict

Kingston SSDNow UV400 is targeted at budget users who want to get more performance out of their computers, by replacing traditional hard drives with affordable SSD drives. If this is what you want, then Kingston SSDNow UV400 is a good choice. It is much faster than traditional hard disks, the capacity is generous enough for most computers and you won't spend a lot of money when purchasing it. The only downside is endurance. While at this point there is no data on how long SSD drives with TLC NAND tend to last, most probably it won't be as long as more expensive SSD drives last. If money is an issue, than Kingston SSDNow UV400 might be the best choice for you!
