As MLC gradually becomes apoptotic, it is no longer difficult to make choices:
The MLC has become a niche option, which is probably what everyone did not think of a few years ago. With the discontinued production of a large number of classic MLC models such as the Intel 520/530 and the Hungry Shark ARC100, we have been forced to the TLC era whether we liked it or not. This is not a step backwards, but it is a response to the need for cost reduction in the consumer market. .
Do you still need to entanglement MLC or TLC? I think that after the endurance tests on TR150 and UV400, many people already have the answer in mind. It's not that TLC really catches up with the durability of MLC, but that the durability of high-quality TLC is sufficient for many home conditions. There is no need to insist on MLC in order to use less than the margin. To be honest, the daily use of TLC life is indeed enough, but if you write frequently, such as doing video rendering, transcoding, or writing a TLC for a carousel like I do, the written lifetime of the TLC is absolutely problematic, according to TLC. Sandisk's Datasheet, x300's TBW is only 80TB, and the upgraded x400 version is still 80TB, with 512G and 1TB capacities being 160TB and 320TB, respectively.
Since the surface of MLC flash SSDs can be selected very narrowly, here I would like to provide you with several recommended models:
128G Recommended Plextor M6S Plus:
The M6S Plus may be the masterpiece of the Marvell 88SS9188 host. The M6S Plus with Toshiba's 15nm MLC flash memory has no price advantage for many TLC flash products, but the increased purchase cost is not too much. The write continuity brought by MLC flash memory is the biggest advantage of M6S Plus. Even running runners will like the thrill of not having SLC cache and running. According to my observations, the M6S Plus 256G has been out of stock nationwide for some time in JD. 128G is now out of stock, and it is not clear whether it is a precursor to discontinue production. If it is needed, it will be purchased through Taobao channel, with a minimum of 459 bags.
Plextor M6S 128G SATA3 solid state hard drive 429 yuan very practical best-selling hard disk Jingdong direct link View Encyclopedia The Toshiba Q200EX is sandwiched between the Q300 and Q300Pro. It has always been the existence of an artifact. As an MLC product at the same time, the price can be linked to Samsung's TLC product. Who can easily reject him? The Q200EX started from 240G capacity. At present, Jingdong has only 240G models, and there is nothing to be entangled in capacity. Jingdong sells for 699, Taobao 2.5-inch version of the lowest 609, M.2 version can be cheaper.
Toshiba (TOSHIBA) Q200EX Series 240G M.2 Solid State Drive 699 yuan This is the M.2 version of Toshiba Q200EX, the speed and 2.5 inch package models have little difference, the nominal sequential read speed up to 550MB/s, the order Write speeds up to 510MB/s. With MLC flash memory particles, compared with TLC particles, they have a longer life and a stable transmission speed. After the storage data reaches a certain level, it will not lose speed. However, the transmission bus is SATA 6Gbps, non-higher speed Jingdong direct link to encyclopedia Other more, list Taobao, Jingdong find it
Flash di:
Retail: SanDisk Plus Z25, SanDisk Extreme Pro
OEM: SanDisk X300S, SanDisk X210, SanDisk Z400S (15nm)
Intel:
Retail: DC S3700/3500/3610/3510/3520 series (exclusive Intel main control, 5 series read-intensive, 6 series read-write hybrid, 7 series write-intensive, personal recommendation S3500 480G/800G, S3700 400G, New from S3610 is not bad)
Intel 530 msata (This is a lot of brand new, warranty around 2020, I got a point of interest from a 51nb a business, are assigned to a friend. Add a transfer box becomes SATA, and speed is basically lossless)
Intel 535 may have a small amount of inventory, but this 16nm hynix+SF2281 VB2 can only be said to be reliable. But after all MLC.
OEM: No warranty, it is recommended not to buy or not afraid of
How to identify if it is a retail version of Intel Solid State
Referring to this [point me to point me] inside the firmware list, not this inside, or a very big difference (such as the DC S3500 factory firmware D2010370, later updated to D2012370 this is normal), but if the firmware on the label if and The difference between this list is too large, or similar OEM disk LAFi, LFBi, is absolutely no official warranty, only through the corresponding OEM business warranty.
Magnesium/Intelligent
Retail: MX200 This is still a bit inventory, the price should not be low, this disk is generally good, at least the problem of the swap is much better than the M500 M550 MX100 (I personally feel that the solid-state energy-saving and MB lost connection)
OEM: M600 no warranty haha
I am not familiar with Samsung and I dare not comment indiscriminately.
Simply pursuing large capacity, the TLC model can also guarantee endurance (I wrote less than a month, wrote more than 25TB, ha ha ha ha, apparently will not consider long-term use of TLC). The currently available high-performance NVMe SSD is still not very widely available, and both Micron and Western Digital have not entered the market. The Intel 750, Samsung 960 series and Plextor M8Pe are all available for selection in the major products. If the budget is not enough, and you want to experience MLC flash high-performance products, you can consider the GALAXY armored M.2 PCIe, PS5007-E7 main control with a third-party package Toshiba 15nm MLC, the price compared to other brands have certain advantages. Intel's shameless 600P is also a path plan. The Bank of China has 5 years of protection. There is no advantage other than this. It does not support TLC write-through. When the cache is used up, it immediately drops to the 100MB/s sequential writing speed. However, the entry usage is still good, with ASRock. The deskmini is very good.
ASRock DeskMini 110/COM (Intel H110/LGA 1151) 999 yuan ASRock DeskMini 110/COM is a machine that locates commercial machines, strictly speaking, it is actually a commercial machine chassis and a Mini-STX motherboard. Small space has gained a volume advantage, only 1.92L inside, but the graphics card basically do not have to think. Internal H110 motherboard, support LGA1151 specifications of the CPU, choose a variety, but the cooling fan also need to buy their own. With two DDR4 Jingdong direct links to Wikipedia 
Intel (Intel) 600P Series 128G M.2 2280 Interface Solid State Drive 519 yuan Jingdong direct link In addition to the models mentioned above, Kingston also has some MLC flash SSD products still on sale, such as the classic V300 series, HyperX Fury, HyperX Savage, but Savage prices have no advantage, V300 and Fury's SandForce program is too old I don't know if I have changed the flash memory with a few clicks. To be fair, I don't know what kind of performance level they are currently selling, and I can't compare and recommend them. Kingston is said to be a large U disk, but it is indeed an access program, there is no place for color
TLC SSDs are being routineized:
With regard to TLC SSDs, apart from Samsung, the rest of the brands are nothing more than Marvell, PHISON and SMI. No matter if they are big manufacturers or small businesses, they are tending to assimilation. It is relatively easy to compare prices and measure after-sales levels with the program products. Now.
With the same hosting provider, the details may still be different. For example, the same PHISON master with the Toshiba TLC hardware solution, in addition to the Toshiba Q300 and the hungry shark TR150, some have quietly replaced the lower cost of the PS3111 S11 No external cache configuration, as I mentioned earlier, if you choose between Q300 and A100, I will choose Q300. PHISON's public version of the program has been relatively stable, GALAXY is PHISON public version of the program's main customers, all products are PHISON public version of the program, HOF series use of Toshiba original factory flash memory, armored warlords and armored war will basically use third-party packaging Toshiba flash memory, from the user word of mouth compared to the past several programs with the use of the time to be more stable.
Marvell's NV1120 dual-core main controller already has public firmware. This solution is being widely adopted by many small domestic brands. The performance of stability and compatibility is not yet clear, but it is basically certain that performance is not as good as single-core. PS3111 S11 master. Marvell's other 88SS1074 master solution has not developed many products, and the adopters are basically Dachang products such as Plextor M7V, Kingston UV400, Micron MX300 and Western Digital Blue Blue.
The MX200 750G often starts at 899 and has recently risen to 949. 32G SLC Cache personally feels good. The MX300 broke Samsung's long-term monopoly on 3D flash SSDs. Although the durability of the new flash memory is not known, the unique single-Die capacity of Micron's 3D flash memory creates a little more capacity in the MX300.
And PHISON is mainly used by GALAXY, domestic brands using the SMI program are more, but in addition to some models of the Intel 540s and Western Digital (SanDisk), most brands are used with white film flash memory, or with the original Hynix factory After the replacement of the flash with unknown flash memory, I think there should be no consumer willing to make a SSD purchase as a lucky draw. For the current price of Intel 540s, my personal opinion is that 120G is not worth buying, and 240G is better to buy other MLC products. Although the 540s has the advantage of five-year warranty compared to most other brands, the Samsung 850Evo 120G is even better and cheaper than him. It also has a five-year warranty. Addition of Intel 540s and SanDisk X400 is the level of the radius of 82, as for the three sticks of the price, the individual can only Oh PM961/SM961 price is OK, other can only Oh
In terms of performance, the best SATA interface TLC SSD is still the Samsung 850Evo series, but according to some foreign media evaluations, Western Digital's Blue 1TB model already has the ability to challenge the Samsung 850Evo 1T, but due to send Measuring only 1TB of a model, Western Digital after the acquisition of SanDisk's active display (send test, trial activities, etc.) is relatively small, the public understanding of his performance is not comprehensive. The performance of the Plextor M7V is similar to that of the Samsung 750Evo, both of which offer 2.5-inch SATA and M.2 2280 specifications. If there is no Samsung brand feeling, a slightly cheaper Plextor is a better choice, or choose a little A little more expensive M.2 NVMe product Intel 600p is also available. Performance requirements are not high, especially for stability, also consider Kingston UV400, the price is relatively cheap, and then look down, then there is no need to choose unknown brands for small profits and unknown brands.
Part II: Second Hand SSD Purchase Guide
Solid-state drives have entered the home market for 10 years, and there are already many second-hand discs on the market that have a small capacity but still have a lot of durability. The increase in SSD prices will also allow some players with a small budget to consider buying used discs.
Preferred Dachang products, especially the original self-developed solutions
According to the SSD category of the Forum's second-hand transaction zone, the brand is basically composed of Intel, Plextor, Toshiba, Magnesium, and SanDisk. Of course, this is related to the higher sales of these brands.
In addition to the brand's own influence, these well-known products can easily find relevant evaluation information and user feedback on the Internet, so that they can have a preliminary understanding of its performance before purchasing a second-hand product.
In the SSD solution and reliability, purchase and use recommendations were introduced to the characteristics of the original self-developed program, in addition to high reliability, the possibility of being renovated is relatively lower. Because the public version of the card-opening tool of the master version of the program often leaks in a wide range, it is easy for the profiteers who specialize in second-hand transactions to bring about the possibility of renovation. The following figure shows the SM2256 card-opening tool that has been leaked. The main control program has been widely adopted by many domestic small-brand companies. However, some common fake Samsung and fake Kingston SSDs have also used this master control program. SMI can almost forge any solid surface information
The SMART status information about which master solutions can be cleared by power-on time, write volume, etc. has been refurbished, leaving the post to say at the end. Whether it is "new zero-power" or "almost new" with only a single-digit power-up record, it could be an illusion that a profiteer has forged. Of course, early solid-state SMART data itself is confusing.
In the protection of products more advantages
If you can buy a solid-state drive that has not yet out of warranty, it will naturally give the buyer more protection. If possible, please try to require the seller to provide proof of purchase invoices. The brand that supports Quanguolianbao is of course the best.
Current SSDs generally have a 3-year warranty, and some high-end models will provide 5-year or longer warranty. As long as the expected remaining life as determined by the SMART status is acceptable, even an official warranty of only a few months remains acceptable. After all, most system platform compatibility issues will appear within a short period of time when the SSD is first used.
OEM model and Haitao purchase risk warning
The warranty terms for OEM products are determined by the manufacturer. Even if the product is under warranty, you may still not be able to obtain the original warranty service. The technical support for OEM products is decided by the brand manufacturer. The original toolbox software and the necessary firmware update are all uncertain.
Taobao “foreign garbage†needs to be cautious. These enterprise-class second-hand SSDs are relatively inexpensive and write wear levels vary depending on the conditions of use. Although long-term power consumption does not affect flash memory life, it will affect the power-down of enterprise-class products. The lifetime of the protection capacitor, which in turn affects the reliability of use (losses more than just the power-failure protection function, which creates more problems). Enterprise-class second-hand cannot be considered as a high stability option. Reasonable, like my computer never shut down, hard disk life is not Chen problem? Individuals have reservations about this paragraph
Starting this year, Intel will no longer provide warranty services for boxed Intel SSDs that were originally sold on behalf of non-domestic licenses that were produced after 42 weeks in 2016, which will become apparent on January 1, 2017. This means that Intel’s global warranty service will be The gradual end of the domestic.
Not yet played by JS?
SanDisk, which supports Global Warranty, currently has only consumer-grade spare parts for domestic sales. If the OEM models are to be disposed of by domestic sales, they will only be replaced with consumer-grade models. The specific impact is not yet clear.
In short, retail warranty, OEM look mood warranty
At present, the hungry shark has been closed at the RMA receiving center in Shanghai. All OCZ hungry shark brand SSDs need to be purchased through the purchase channel. For the manufacturer's direct warranty, the company must send the solid state disk to Taiwan after applying on the official website. The return freight is from OCZ. bear. In addition, after the application process may need to provide the original purchase certificate to prove that he is the original buyer of the product, the actual implementation is not yet clear.
Add a magnesium light, magnesium light warranty MX100 BX100 MX200 BX200 MX300, but must be designated merchants to buy the warrants, parallel to pay the money warranty (similar to the English boxed Intel CPU pay 200 warranty), from the production date of the warranty
Currently known SSDs that can be refurbished with certain tools to empty SMART information are:
All SandForce master SSDs (Yes you read that, Intel 520, etc. can all be cleared and refurbished)
Identification method:
1, Intel Toolbox
2, KINGSTON SSDNow SF Updater to see if it is not the beginning of the 180 Signature, not to explain the card was opened.
Do not rule out NB business forged Intel firmware, then we must open the disk to view.
All SMI master SSDs (including the latest SM2256's card-opening tools have flowed out)
The most popular cottage dish after SF2281 loves to use master
Rely on official programs for initial identification, such as Sandisk Dashboard
All JMF master SSD (card out tool outflow, can be cleared)
It seems that there are few big names to use this, but also love to use
All PHISON Master SSDs (including custom firmware versions can also be refurbished, theoretically the Q300 and TR150 are also unsafe)
Magnesium Marvell Master SSD (SMART Clearable)
In this case, only SanDisk's horses are mastering the game, and it is estimated that nobody will do such a thankless task.
Samsung all SATA interface SSD (SMART can be cleared)
We hope you can buy your own favorite
