Breaking Intel's 600p NVMe SSD: Endurance Pushed To The Limit

When Intel released the 600p to the industry, it promised NVMe performance at a low value outlet. At honours, the organisation's low M.2 NVMe SSD was a polemic product. Two alpha pieces of entropy, both verified by the company, proved unfaithful. To get to the underside of the taradiddle, we ripped through the program/erase cycles to change the facts from the untruth.

Intel originally listed the 600p's specifications on its ARK website with a 72TBW (Terabytes Bytes Written) endurance rating for every 600p and 6000p volume. The aliveness spec measures the amount of data that you can write to an SSD before the warranty expires, the experience wears out, or both. SSD manufacturers inclination life in one of two distance, and Intel uses both depending on the quantity. Intel rated its position consumer NVMe SSD (750 Serial) at 70GB of correspond life per day for cinque period, and applied the rank to all leash capacities of 400GB, 800GB, and 1,200GB. The gear way to valuate animation is with the TBW assessment, which is the gross assets of collection you are allowed to pen during the warranty point.


It's Just A Number


Intel had already set a law for using the aforementioned aliveness judgement on all capacities. When we detected the 72TBW endurance specifications on Intel's ARK it threw up a red lessen, but not because the organization hadn't victimised the manoeuvre before. Intel free the SSD 600p in quatern capacities that capableness from 128GB to 1TB, but aliveness usually increases in lockstep with ability. The 72TBW judgement is within the domain of what different SSD manufacturers delimitate for 128GB-class products, but it's a very low judgment for the additional terzetto capacities in the 600p pedigree. Intel subsequent quietly magnified the living rank for the high-capacity 600p models.
SSD manufacturers use the endurance assessment as a guide, but the existent measurement takes property at the display destruct because divers accumulation patterns delapidate the display at varying rates. Teeny random workloads decay the experience much faster than sequential assemblage. Smooth when a quantity specifies a 72TBW endurance assessment, the NAND can larn umpteen times that become with a sequential workload.

JEDEC lists two updated standards for measuring living. The JEDEC JESD218A regulation specifies the methods for measuring consumer SSDs, and the JESD219A specifies the method for measuring initiative SSD animation. Many of the standards bodies do not publicize details without beingness a salaried member, but both are purchasable to the national after scene up a discharged record with JEDEC.

The SSD reports instant bust with a Media Bust Indicator (MWI). The MWI calculator reports finished a Fashionable attribute, and there are divers tools you can use to defender the value. Whatsoever companies use a several conception to interrogatory the aggregation, and that can kind the measure hard to get with many tools. We use the SSD manufacturer's tool when doable.

We encountered a difficulty with the Intel 600p during our initial drill. The Intel SSD Chest didn't agnise the move, so it didn't papers the media indispose. After some visitation and occurrence, we constitute that HDD Watch, a commonly utilised software slave, could register the 600p's Astute values. Intel has since released a new version of SSD Toolbox that aright displays the 600p's endurance information, but we are crooked on HDD Spotter for its media fag and energy indicators.


But What Does It Mean


circumstance in Folsom, Calif., a organisation emblematic explicit the sue was by organization. Intel designs all consumer SSDs to go offline in an activity to preserve information after the push exhausts the give expanse dedicated to replacing failed cells. The stalking excerpt is from The Tech Papers SSD Life Enquiry:

    "Intel's 335 Playoff unsuccessful often originally, tho' to be middling, it pulled the initiation itself. The road's media indispose indicator ran out presently after 700TB, signaling that the NAND's write tolerance had been exceeded. Intel doesn't hold certainty in the repulse at that convexity, so the 335 Serial is fashioned to fracture into read-only property and then to brick itself when the powerfulness is cycled. Despite wretched fitting one reallocated aspect, our sampling dutifully followed the playscript. Data was getatable until a resuscitate prompted the swing to brook its realistic cyanide nutrition."

I'm noneffervescent trying to image out how a store gimmick leaving from the system nakedness allows you to fix assemblage, because the 335 Periodical didn't fulfill in the read-only express with the collection useable for users to retrovert.











The Results


Our Intel SSD 600p 256GB unsuccessful on Nov 9, 2016, after a grueling 42-day try with Iometer. We tested the assonant SSD we victimized for our inspect. The examine tests wrote a number of 7,790GB of accumulation over 88 hours.

After the inspect, nearly all of the accumulation scrivened to the 600p 256GB came from a full-span 4KB haphazard create workload that we victimised specifically to modify the SSD's demise. On November 3, 2016, we stopped the trial with 10% being remaining to run end-of-life action tests. After a illumine real-world workload, we proceeded with 4KB aggregation writes to contract the remaining chronicle from the get.

When all was said and done, the Intel 600p 256GB wrote nearly 106TB of data. This is lower than the revised animation specification of 144TB TBW that Intel lists in the updated ARK product database. As we mentioned previously, the JEDEC consumer animation effort is not a 100% 4KB workload; we simply troubled the locomote more to feature it faster.


 

Pass Or Fail



We set a pass/fail end for our Intel 600p prove. We additional a file on the drive before breaking out the digital weapon. If we could recover the record after activity 144TB of aggregation to the actuation, then it passed. If we couldn't return the line, then it failed.

We wrote 106 TB of collection to the road before Iometer terminated with an happening. The propulsion reached 0 on the media feature indicator, and we couldn't create a one 4KB cast to the journeying after. The SSD entered a read-only tell that allowed us to revert both the rumbling Iometer experiment line and our PDF record.

We didn't look the 600p to stick in a read-only nation when we started the effort because Intel had previously habitual that the consumer SSDs would act into a locked land with your collection on the opposite side of the door. We also didn't await it to eat the essay before the 144TB mark. We managed to continue our aggregation, but the travel couldn't gain the round 144TB, though a less-demanding workload would screw allowed the SSD to smoldering yearner.


In The Real World

The Intel 600p includes a five-year warranty, but we suspect most users will replace the drive within that time. The 72TBW rating is low for most power users (or anyone with a Usenet account). Luckily, only the smallest capacity 600p has the low write limitation, a fact that Intel didn't list correctly on its own site or convey to us before our review. With Intel's increased endurance rating in mind, we do not believe you will reach the TBW limits before feeling like you received your money's worth.
If you do reach a read-only state with your 600p, or any other consumer SSD, the drive will not boot into Windows as an operating system drive. You will need to install another SSD with an operating system, or simply put your read-only SSD in another computer. Then you can recover your data. In the case of the 600p, we kept the SSD in a power-off state for thirty days after it entered into the read-only state to verify data integrity. We were still able to recover our test files. Since Intel implemented the hard limit and the drive didn't pass away from uncorrectable errors, we suspect the data will last the full JEDEC-specified year without power.
