If you need fast and reliable store , there ’s no interrogative sentence — you should choose one of thebest SSDsavailable , as select the right one can give you years of honest storage . However , by definition , SSDs do n’t last forever . The NAND ostentation remembering that powers them only has a finite turn of write and erase cycles , which mean that over time , your SSD will fail .
The question is , how long do SSDs really last ? Do you involve to occupy about that when you rat , and what are the signs to look out for ? We ’ll explore all of that and more in this article .

How long do SSDs last?
On mediocre , many SSDs may operate well for five to 10 years before show signs of bankruptcy . However , this estimate can commute depending on the picky SSD in question . Things that may prolong or contract the life of an SSD include the type of NAND split second memory it uses , the workloads it handles , and how often ( and how to a great extent ) it ’s in use .
For something that ’s responsible for storing information , there ’s surprisingly little intel on the average life of an SSD . Although SSDs may work well for up to 10 age , the mean SSD will go sooner than that , and late studies lay claim that SSD unsuccessful person becomes likelier with time more so than with usage . Long story short : It ’s OK if you use your SSD a whole lot every twenty-four hours . clock time alone will still do its work whether you employ it gently or not .
According to aresearch paperfrom by Bianca Schroeder of the University of Toronto and Google ’s Raghav Lagisetty and Arif Merchant , NAND flash drives have a much lower replacement pace than good onetime HDDs . In the early daylight of consumer SSDs , some mass claimed that they ’d be much less reliable than HDDs , but this turned out to be acommon PC myth . On the other bridge player , that same field of study found that SSDs get more uncorrectable errors and bad blocks than HDDs , which does n’t of necessity lead to full crusade failures . It ’s more about degradation over a sure period of time .
Backblaze , a cloud warehousing and backup company , also share some interesting insights on SSD reliability by write mid - yearreports . In mid-2023 , the companionship was using a humongous 3,144 SSDs in its store server . In the 2nd quarter of 2023 , out of those 3,144 SSDs , only eight failed . The fellowship ’s annualized failure rate ( AFR ) vacillate between 0.36 % and 1.72 % .
What ’s perhaps more interesting is that Backblaze also reckon the average age of bankruptcy for its SSDs . In the 2023 report , the companionship find a total of 63 failed SSDs . Taking into explanation power - on hours ( POH ) , Backblaze determined that the mediocre age of an SSD was just 14 months . But this information is misleading — the average SSD years in Backblaze ’s entire fleet is just 25 months . With sentence , the average age of SSDs at the time of failure will likely increase .
Wanting to determine just how long SSDs last is specially unmanageable because almost every individual report talking about SSDs in the context of data point centers , not consumers . It ’d be arduous to measure the exact average life-time of a consumer SSD , sketch or not , because there ’s more to it than just fourth dimension , although it does seem like prison term play the adult part . How you habituate your SSD is also a ingredient — regular use of television redaction software likeAdobe Premiere Pro or alternativeswill have a intemperate impact on its lifetime than day - to - day documents and spreadsheets .
Another thing to keep in mind is that many SSDs will just never fail . You ’ll sooner exchange your entire system of rules than see the SSD die . Some SSDs will fail and some wo n’t , and there ’s no easy elbow room to presage what will go on to yours .
What contributes to the lifespan of your SSD?
Although the lifespan of an SSD might seem fairly equivocal , every SSD has an count on amount of data it can handle before it ’s at risk of break down . Let ’s soften it down .
TBW, DWPD, and MTBF
When you shop for an SSD , you ’ll often see various spec that estimate how long the SSD should function before things go south : terabytes written ( TBW ) , drive writes per mean solar day ( DWPD ) , and mean fourth dimension between failures ( MTBF ) . Some manufacturers will lean just one of those metric unit , while others may list all three . This is why determining how long an SSD can last is not an accurate scientific discipline — after all , each of those metrics refers to something else .
TBW is a measure of the full amount of data that can be written to your SSD before it wear out . This is the most usually used metric that comprise the survival of an SSD , but in reality , it ’s unlikely that you ’ll ever hit that detonating machine . Many of the best SSDs currently available have TBW evaluation that achieve 1,200 TB and above . Assuming that you compose 100 GB of data per week to your SSD — which may not be much on some weeks , but should be plenty on most weeks — your TBW will run out after 230 days of continuous usage .
In short : High TBW is good because it read to adept endurance , but you ’re unlikely to ever surpass the TBW on any SSDs . Even sure-enough drives with a small 300 TB TBW will last for years and years with normal utilization .
DWPD is another system of measurement used to gauge the survival of your SSD . It indicate how many times the entire capacitance of the SSD can be written to per Clarence Day over the warranty time period of the parkway . For model , the Samsung 990 Pro 2 TB offer a five - year warranty and has a DWPD rating of 0.3 . This means that you could indite up to 600 GB per 24-hour interval for five geezerhood before you habituate up the entire terminal point .
MTBF , on the other hand , is a dependability system of measurement that bear on to the time between failures , value in hours . In an SSD , it merely gauge how probable it is that your SSD will die during normal military operation . The aforementioned Samsung 990 Pro has an MTBF of 1.5 million hr , meaning that it ’s expected to lead alright for 1.5 million minute before it might fail . That ’s 171 years , which , again , is a crazy phone number . plainly , Samsung ca n’t try an SSD for 171 year before shipping it , though , which is why MTBF refers to a proportion between the accumulative working time of those SSDs to the numeral of SSDs that die . In other words , an SSD with an MTBF of 1.5 million hours that ’s melt 24/7 for a year has a 0.58 % fortune of failing during any given year .
For all of those metrics , it ’s significant to call back that they ’re statistical measures that do n’t guarantee that your SSD will hold up for that long . ( Without the help of our robot overlords , none of us will be around to see what bump to our SSDs in 230 years , anyway . )
It ’s just an appraisal , and some SSDs will break down in a twelvemonth while others wo n’t flush it at all and will simply be replaced at one point .
Age
All metrics aside , the long time of your SSD is the determining factor in how long it ’ll last . You ’re unlikely to ever exceed the TBW in a innovative SSD , but time and use alone will wear it out . It all make out down to the endurance of the oxide level in the NAND flash memory used in an SSD , which deteriorates with each programme / erase ( P / E ) wheel . The NAND cell in your SSDs are sham by each and every P / einsteinium cycle , and eventually , they ’ll bust out . As more and more NAND cells wear thin out , your SSD ’s power to store data will be diminished .
A drive under heavy utilisation is therefore likelier to wear out sooner , but one sidereal day , the SSD will wear out one way or another . Most SSDs occur with a limited warranty of three to five yr — the repose is up to luck and usage .
Type of NAND flash memory
Another understanding why it ’s hard to estimate the average lifetime of an SSD is that there ’s no universal type of SSD to concern to . Depending on the NAND flash memory used in a particular SSD , it may have a high or lower predicted number of write cycles .
The terminal figure NAND refer to a non - volatile type of flash memory that continue to store your data even when you turn your PC off . This makesSSDs dissimilar from RAM , which is fickle and does n’t continue any data after you sign out for the sidereal day . NAND is also what makesSSDs different to HDDs , which employ spin charismatic disks to store data , which makes them slower and more prone to physical damage .
The eccentric of NAND flash memory in SSDs are :
Some maker started using a proficiency call 3D NAND , increasing density and storage capacity without make the SSD itself bigger . This technology can be used with any type of NAND , from SLC to QLC . Some SSD specs only heel “ 3D NAND ” without specifying the case , but if you dig profoundly , that information can usually be found on the manufacturer ’s website .
Most SSDs these day come with TLC NAND , which fix them more affordable , but less undestroyable .
Signs of SSD failure
If your SSD is fail , it ’s usually very easy to see . Over the days , I ’ve only attend one SSD fail before it was replaced , but it was clean as Clarence Day . The computer slow down down to intolerable levels , so much so that launching Chrome took over 30 minutes . Checking the Task Manager revealed that the magnetic disk was running at 100 % even when nothing else was undecided . Luckily , I was able to enamour this before the decimal point of no return and recollect the data before getting rid of that SSD .
Here are some signal to keep an oculus out for :
It ’s important to remember that losing your SSD may cost you all of your datum . That ’s whybacking upis so important , but also periodicallytesting your SSDfor signs of failure is a good estimate . It ’s best to act before you notice any signs of bankruptcy , as this may give you some time to transfer your data elsewhere and buy a refilling driving force .
