Waxaan soo marnay waddo dheer tan iyo markii 5-tii ugu horeysay ee Hard Drive-yada ah lagu keenay diyaarad xamuul ah oo lagu wareegay fargeeto. Maalmahan waxaad haysataa fursado badan oo waaweyn oo loogu talagalay baahiyahaaga kaydinta xogta. Dhab ahaantii, waxay u badan tahay inaad leedahay doorashooyin badan! Doorashadan kala duwan waxay keeni kartaa jahawareer. 

Marka aad iibsanayso darawal adag maanta, waxaad haysataa saddex nooc oo wadis ah: SSD , HDD ama SSHD . Maraq la soo gaabiyey ayaa laga yaabaa inay ku tijaabiso inaad iska tanaasusho oo aad dib ugu laabato kiniiniyada dhoobada ah, laakiin waxaanu kaa caawin doonaa inaad ogaato midka ugu fiican baahiyahaaga.

Waa maxay SSDs, HDDs iyo SSDs

Talaabada ugu horeysa ee cad ee waxaas oo dhan waa in la sharaxo waxa ay yihiin saddexdan nooc ee wadista iyo ballaarinta macnaha erayada gaaban ee dhabta ah.

SSD-yadu waa wadayaasha Dawlad adag. ^{(SSDs are Solid State Drives.)}Ma haystaan ​​qaybo dhaqaaqa si kastaba ha ahaatee waxay isticmaalaan xusuusta flash-ka ee xaaladda adag^{(solid state flash memory)} . 

HDDs waa Hard Disk-yada. ^{(HDDs are Hard Disk Drives.)}Kuwani waa wadiiqooyinka farsamada dhaqameed ee caadiga ahaa ilaa dhawaan. Waxay isticmaashaa saxannada wareegta ah oo lagu daboolay walax birlab ah si ay u kaydiso xogta. Madax wax-akhris/qoraal ah oo yaryar^(Tiny) ayaa ka duulaya dusha saxannadan oo ku dul sabeynaya barkin hawo ah qayb ka mid ah ballaca timaha.

SSHDs waa wadayaasha isku-dhafan ee Gobolka Adag. ^{(SSHDs are Solid State Hybrid Drives.)}Qaybta "isku-dhafka" ee magaca ayaa tilmaamaysa xaqiiqda ah in darawalladani ay ka kooban yihiin labadaba xusuusta adag iyo saxanadaha farsamada. Software-ka xariifnimada^(Clever) ah ee ku dhex jira darawalka ayaa tilmaamaya faylalka ay tahay in lagu shubo xusuusta adag ee gadaasha. Markaa markaad rabto inaad gasho faylalka lagu shubay kaydka adag ee gobolka, waxaad heli doontaa waxqabad la mid ah SSD saafi ah .

Waxqabadka

Isagoo ka hadlaya waxqabadka, waxaa jira kala sareyn cad marka ay timaado isbarbardhigga. 

Wadayaasha Dawlad Adag^{(Solid State Drives)}

SSDs waa nooca ugu dhaqsiyaha badan ee wadista marka la barbardhigo. SATA 3 SSD oo tayadeedu wanaagsan tahay ayaa in ka badan ama ka yar ku dhufan doonta xadka nooca isku xidhka ee leh wax akhrinta iyo qorista ku dhawaad ​​600MB/s. 

Laakiin SSD^(SSDs) -yadu waxay sidoo kale ku yimaadaan qaabab kale, sida NVME . NVME SSDs oo leh xawaare wax-akhris iyo qori ah oo ku dhow 3500 MB/s ayaa hadda ah meel caadi ah, jiilka cusub ee wadista ka shaqeeya in ka badan 5500 MB/s ayaa soo socda.

Wadayaasha Isku-dhafka Gobolka Adag^{(Solid State Hybrid Drives)}

SSHD-yada waxa kaliya oo loo heli karaa sida darawalada SATA , markaa waligood kama dhaafi karaan xadka xawaaraha 600MB/s ee xidhiidhka. Sidoo kale, waxay kaliya ku gaari karaan xawaaraha SSD waqtiyada gaaban ee dillaaca. Asal ahaan ilaa inta kaydka SSD uu xogta ku jiro. Markaa mar kasta oo kaydka SSD -gu uu weynaado , waa ay dheeraanaysaa tirada wakhtiga ay ku ilaalin karto xawaaraha xogta sare. 

Waxa kale oo ay ku xidhan tahay in SSD^(SSHD) -gu uu hore ugu shubay faylalka saxda ah ee kaydinta. Haddii aysan taasi dhicin waxaad dib ugu dhici doontaa heerka xawaaraha darawalka adag.

Hard Disk-yada^{(Hard Disk Drives)}

Dareewalada adag ee dhaqameedku waa kuwa ugu gaabis badan. Halka kuwa sare ee 7200 RPM ay gaari karaan ku dhawaad ​​230MB/s iyo darawallada tijaabada ah ayaa la muujiyey inay garaaceen ku dhawaad ​​500MB/s, waditaanka 5400 RPM ee caadiga ah waxaad ka heli doontaa laptop ama kombuyuutar desktop meelna uma dhowa. Xawaaraha u dhexeeya 30MB/s iyo 110MB/s ayaa aad uga caadi badan.

Cabirka Jirka

SSD-yada waxaa lagu soo saaray 3.5"iyo 2.5" cabirrada wadista caadiga ah iyadoo la isticmaalayo isku xirka SATA . Xaaladdan oo kale waxay qaataan mugga la mid ah darawallada farsamada ee cabbirradaas. Si kastaba ha ahaatee, taasi waxay u tahay waafaqid wadista, ma jirto baahi dhab ah oo ay u qabaan inay sidaas u weynaadaan.

Qaababka NVME Drives -ku waxa ay la le’eg yihiin ul ka mid ah ^(NVME)RAM -ka desktop-ka , waxayna si adag u fadhiyaan Motherboard-ka. Taas oo la macno ah in aanay haba yaraatee qaadan meelo baabuurta lagu kaxeeyo.

SSHD^(SSHDs) -yada iyo HDD-yada^(HDDs) waxaa lagu heli karaa oo keliya 3.5"iyo 2.5" qaab isirrada. Waxay sidoo kale aad uga culus yihiin SSD^(SSDs) -yada , markaa waxay ku dari doonaan inta badan nidaamka, ugu yaraan marka loo eego shuruudaha.

Qiimaha iyo Awoodda

Qiimaha SSD^(SSDs) -yada ayaa hoos u dhacay dhowrkii sano ee la soo dhaafay, laakiin darawal tayo leh ayaa wali ku amri doona qiimaha ugu sarreeya gigabyte kasta oo nooc kasta ah. SSD^(SSDs) -yada sidoo kale waa kuwo xadidan awoodooda ugu badan. 

Wadayaasha ugu waaweyn ayaa hadda cabbirkoodu yahay 2TB, laakiin waxay leeyihiin qiimayaal indho-indhayn ah oo boosas badan ah. Sida caadiga ah nidaamyada waxay ku qalabaysan yihiin 250GB ilaa 500GB drives. Taasi wax badan kuma aha adduunyada 100GB ee ciyaaraha fiidyaha iyo fiidiyowga 4K^{(4K video)} !

SSHD^(SSHDs) -yada iyo HDD-^(HDDs) yadu waxay leeyihiin qiime isku mid ah, iyadoo SSD^(SSHDs) -yada ay ku kacayaan xoogaa ka badan iyada oo ay ugu wacan tahay ku daridda waxoogaa yar oo kaydinta SSD ah iyo qalab elektaroonik ah oo aad u casrisan. Labadan nooc ee wadista baabuurtu waxay leeyihiin qiime jaban halkii gigabyteba waxaana lagu bixiyaa awood aad u weyn, oo ka badan 10 TB dhamaadka sare.

Kalsoonida

Biyuhu waa wax yar oo dhoobo ah marka ay timaado isku halaynta noocyada kala duwan ee darawalnimada. Waxaan haynaa xog aad u badan marka ay timaado isku halaynta wadista farsamada. Kuwaani waxay sida caadiga ah haystaan ​​MTBF (Waqtiga Dhexdhexaadka ah ee Guuldarrada)^{(MTBF (Mean Time Between Failures))} oo ah 100,000 saacadood. Guuldarrooyinka waxaa inta badan sababa qaybaha makaanikada oo gaboobay. Markaa xitaa haddii aadan aad u isticmaalin darawalkaaga adag, laakiin uu ku sii socdo, wuu guuldareysan doonaa ugu dambeyntii.

Aragti ahaan SSD^(SSDs) -yadu waa inay waligood jiraan, laakiin nooca badan ee la awoodi karo ee xusuusta SSD ee aad ka hesho darawallada macaamiishu wax yar ayay dataan mar kasta oo aad xog u qorto. Kani waa mowduuc dhib badan, marka waxaan kugula talineynaa inaad akhrido Wax kasta oo aad u baahan tahay inaad ka ogaato SSD Wear & Jeex^{(Everything You Need To Know About SSD Wear & Tear)} si aad si fiican u fahanto arrinta. 

Awooda sare ee casriga ah ee SSDs , runtii dhib maaha. Tijaabooyinka jirdilka SSD^(SSD) waxay tuseen inay sii waaraan in ka badan cimrigooda qoraalka xogta la qiimeeyay. Si kastaba ha ahaatee, waxay ku noqotaa meel laga welwelo SSD^(SSHD) -ga oo leh kayd yar oo SSD ah oo si joogto ah loogu qoro meel haynta ku meel gaadh ah. 

Kiisaska Isticmaalka lagu taliyay

Hadda oo aan soo koobnay meelaha adag iyo kuwa daciifka ah ee darawalladan kala duwan, waa waqtigii laga hadli lahaa darawalada ugu fiican ee kiisaska isticmaalka.

SSD^(SSDs) -yada waxaa sida ugu wanaagsan loogu adeegsadaa nidaamka kaxeeya nidaamka hawlgalka iyo codsiyada ka faa'iidaysta xawaaraha SSD . Kuwaas waxaa ku jiri doona tifaftirayaasha fiidiyowga, codsiyada wax soo saarka iyo dabcan ciyaaraha fiidiyowga. Maadaama ay qaali yihiin, SSD^(SSDs) -yada waxaa lagu lumiyaa faylalka warbaahinta ama kaydinta xogta.

SSHD-yadu^(SSHDs) runtii waa ikhtiyaar macquul ah oo keliya kombuyuutarrada laptop-yada kuwaas oo leh kaliya hal meel oo wadista. Haddi ay tahay sababtoo ah miisaaniyadaadu way xadidan tahay ama aad u baahan tahay meel banaan oo gudaha ah, SSHD waxa ay bixisaa wax qabad maalinle ka maalin kor u kaca iyadoo waliba bixisa kayd badan oo jaban.

Wadayaasha HDD^(HDD) waxay ku fiican yihiin inay kaydiyaan faylalka warbaahinta waaweyn, kaydinta ciyaaraha fiidiyowga iyo codsiyada kale iyo nooc kasta oo xog ah oo aan u baahnayn xawaaraha SSD si loo isticmaalo. ^(SSD)Wadayaashani waa raqiis oo haddii aad isticmaasho darawallada HDD -ga dibadda ah ee aan si joogto ah u shaqayn, waxay sidoo kale sameeyaan xalal kayd ah oo wanaagsan.

Nidaamyada yeelan kara wadiiqooyin badan xalka ugu fiican maanta wuxuu u muuqdaa inuu yahay darawal weyn oo SSD ah, oo leh HDD weyn oo ah wadista kaydinta ballaaran ee sare. Si kastaba ha noqotee, iyada oo qiimihii SSD hoos u dhacayo oo cabbiraduna kor u kacayaan, mustaqbalku wuxuu u muuqdaa inuu yahay xaalad adag. Weli halkaas ma nihin, laakiin maalinta ay kaydinta SSD ka jaban tahay kaydinta HDD waxaa laga yaabaa inaanay ka fogayn sidaad u malaynayso.

SSHD vs SSD Drives: Which Is Better?

We have come a long way since those very firѕt 5 MB hard drives were delivered by cargo plane and mоved around with forklifts. These daуs you have рlenty of greаt optionѕ for your data ѕtorage needs. Actυally, you probably have too mаny choices! This variety of choіces can lead to some confusіon. 

When buying a hard drive today, you have three drive types: SSD, HDD or SSHD. This acronym soup might tempt you to just give up and go back to clay tablets, but we’ll help you figure out which is best for your needs.

What Are SSDs, HDDs and SSHDs

The obvious first step in all of this is to explain what these three drive types are and expand on what those acronyms actually mean.

SSDs are Solid State Drives. They have no moving parts whatsoever and make use of solid state flash memory. 

HDDs are Hard Disk Drives. These are the traditional mechanical drives that were standard until quite recently. It uses spinning platters covered in a magnetic substance to store data. Tiny read/write heads flit across the surface of these disks floating on a cushion of air a fraction of a hair’s width.

SSHDs are Solid State Hybrid Drives. The “hybrid” part of the name refers to the fact that these drives contain both solid state memory and spinning mechanical disks. Clever software inside the drive figures out which files should be loaded onto the solid state memory in the background. So when you want to access files that have been loaded onto the solid state cache, you’ll get similar performance to a pure SSD.

Performance

Speaking of performance, there’s a clear hierarchy when it comes to this comparison. 

Solid State Drives

SSDs are the fastest type of drive in every comparison. A good quality SATA 3 SSD will more or less hit the limits of the connection type with read and write speeds at around 600MB/s. 

But SSDs also come in other formats, such as NVME. NVME SSDs with read and write speeds around 3500 MB/s are commonplace now and a new generation of drive that runs in excess of 5500 MB/s is on the horizon.

Solid State Hybrid Drives

SSHDs are only available as SATA drives, so they can never exceed the 600MB/s speed limit of the connection. Also, they can only achieve SSD speeds for short bursts of time. Basically for as long as the SSD cache has data in it. So the larger the SSD cache, the longer the amount of time it can sustain high data speeds. 

It also depends on whether the SSHD has pre-loaded the right files into the cache. If it hasn’t you’ll fall back to standard hard drive speeds.

Hard Disk Drives

Traditional hard drives are the slowest of the bunch. While high-end 7200 RPM drives can attain around 230MB/s and experimental drives have been shown hitting almost 500MB/s, the typical 5400 RPM drive you’ll find in a laptop or desktop computer comes nowhere near that. Speeds of between 30MB/s and 110MB/s are much more typical.

Physical Size

SSDs have been produced in 3.5” and 2.5” standard drive sizes using the SATA connector. In which case they take up the same volume as mechanical drives in those sizes. However, that’s for drive bay compatibility, there’s no actual need for them to be that large.

NVME format drives are about as large as a stick of desktop PC RAM and sit tightly against the motherboard. Which means they take up no drive bays at all.

SSHDs and HDDs are only available on 3.5” and 2.5” form factors. They are also significantly heavier than SSDs, so they will add to the bulk of the system, at least in relative terms.

Cost and Capacity

The cost of SSDs have come tumbling down over the last few years, but a quality drive will still command the highest price per gigabyte of any drive type. SSDs are also relatively limited in their maximum capacity. 

The largest drives are currently 2TB in size, but have eye-watering prices for that much space. So typically systems come equipped with 250GB to 500GB drives. That’s not much in a world of 100GB video games and 4K video!

SSHDs and HDDs have similar pricing, with SSHDs costing a bit more thanks to the inclusion of a small bit of SSD storage and more sophisticated electronics and firmware. Both of these drive types have a low per-gigabyte cost and are offered in huge capacities, exceeding 10 TB at the high end.

Reliability

The water is a little muddy when it comes to the reliability of these different drive types. We have a huge amount of data when it comes to the reliability of mechanical drives. These typically have a MTBF (Mean Time Between Failures) of 100,000 hours. Failure is usually caused by mechanical components wearing out. So even if you don’t use your hard drive much, but it stays powered on, it will fail eventually.

Theoretically SSDs should last forever, but the more affordable type of SSD memory you get in consumer drives wears out a little every time you write data to it. This is a complicated topic, so we suggest you read Everything You Need To Know About SSD Wear & Tear to get a good grasp of the issue. 

In modern high capacity SSDs, it’s not really a problem. SSD torture tests have shown them lasting far beyond their rated data writing lifespans. However, it does become a point of concern on an SSHD with a small SSD cache that is constantly being written to as a temporary holding space. 

Recommended Use Cases

Now that we’ve covered the strong and weak points of these various drives, it’s time to talk about which drives are best for which use cases.

SSDs are best used as system drives that host the operating system and applications that benefit from SSD speeds. These would include video editors, productivity applications and of course video games. Since they are expensive, SSDs are wasted on media files or data archiving.

SSHDs are really only a sensible choice for laptop computers that only have a single drive bay. Whether it’s because your budget is limited or you need a lot of internal space, an SSHD offers some day-to-day performance increases while also offering plenty of cheap storage.

HDD drives are perfect to store large media files, backups of video games and other applications and any other data types that don’t require SSD speeds to use. These drives are cheap and if you use external HDD drives that don’t run constantly, they also make for good backup solutions.

In systems that can have multiple drives the optimal solution today seems to be an SSD main drive, with a large HDD as a secondary mass storage drive. However, with SSD prices going down and sizes going up, the future does seem to be purely solid state. We aren’t quite there yet, but the day when SSD storage is cheaper than HDD storage may not be as far away as you’d think.
