Ill start with the unknown first. Logevity. Who knows if this SSD is really premium or if its just a false claim. Ive never heard of Timetec before and if it was my own money being put on the line, I probably would not have given this brand a shot until others gave their 2 cents. Seeing as this is a review unit and I didnt have to pay for it, I was more than happy to see if gems can be found in the SSD space from little known companies. When you read the product description you probably noticed their claim of 530 MBps reads. If you take a look at my attached pics youll see those claims are true and a little more when connected to a SATA port on your motherboard. I did two sets of Crystal Disk Mark tests. a 64 MiB and 1 GiB test connected to SATA and the same tests connected to a USB 3.0 to SATA adapter. USB has some overhead so for the most part, its pretty much always going to be a little slower. That is until we see much higher speed devices. (10, 20, 40 Gbps) Now for the reason why this drive is as fast as it is right now. For one, its empty. When SSDs become close to full, they can slow down significantly. Especially those with SLC caching vs a DRAM cache. Whats the difference? DRAM Cache: It is a separate high speed chip on the PCB of the SSD. A DRAM chip is akin to the memory in your computer, which temporarily stores data for the purpose of accelerating processing. Also, because of this temporary storage function, many read/write processes can directly use the data in the temporary storage, which will be much faster than having to move data to DRAM. However, just like computer memory, the data will be erased automatically when the power is off. SLC Cache: It is not a separate external chip. Since it’s called Cache, it means that it is not really an SLC NAND Flash chip, but a part of the SSDs space in the TLC or QLC’s NAND Flash to simulate the SLC writing method (only 1 bit of data can be written in each Cell), which can effectively improve the read/write performance of the SSD. However, I don’t know if you have noticed the keywords, “a part of the space”? When the sequential write capacity reaches the upper limit of “a part of the space”, (meaning its too close to full) the read/write speed will drop back to the original value of TLC NAND Flash, which is much slower. For SSDs without DRAM Cache, the indicated read/write speeds are basically measured using the SLC Cache function at its optimum. (meaning an empty drive) Compared to DRAM Cache, SLC Cache is stored in TLC NAND Flash, so if it is not erased purposely, the data can be saved continuously and will not disappear due to the drive losing power. Conclusion: Should you get one? I just dont honestly know the answer to that yet. If you are on a REALLY tight budget and you are good about backing up your data, I dont see why you shouldnt give it a shot. If you arent good about backing up and you use your computer/laptop for mission critical things, well, I know all brands are imperfect and can have lemons in the lineup, but you may want to look at a very well known brand like Samsung or Crucial in that case. I will update this review as time goes on or if it prematurely dies on me.

This product is an excellent buy i am totally satisfy and reccomend this to anyone who seek to replace their memory, with this memory my system is working as brand new.

The product was in perfect shape, and works perfectly on an Macbook Air 13 mid 2012. Recommended.

Why Apple couldnt just use an M.2... At any rate this part fits and works well so far. Brought my old MacBook Air back to life after a drive failure.

7 year old MacBook Air was almost out of original 128GB SSD disk space. We didnt need any more power as it is mainly used for email, web browsing and solitaire, so no need for newer laptop. Found this 250 Gb SSD and thought it would do the trick since it took 7 years to max out the original 128. Installation is easy however no tools provided. Luckily I had tools from a recent battery replacement, they are very small torx screws on case. The only problem is with any disk replacement, the license code to Windows Office does not restore from backup so either you have to reenter (assuming you still have that after 7 years, I didnt) or you buy a newer license. Okay the Office 3013 I had was out of support anyway, so time to update.

It aint the fastest SSD I own, but its fast enough for a project that includes delivery to client on a Hard-Drive. Ninety percent of the time, clients dont send the drive back to me.

Exelente

Used win 10 CMD to check write speeds, checked it 4 times. Tried 2 different cables. Write speeds as per win 10 CMD line 102.83, 103.28, 103.37, and 107.49. via USB 3.1.
