TEAMGROUP GX2 512GB 3D NAND TLC 2.5 Inch SATA III Internal Solid State Drive SSD (Read Speed up to 530 MB/s) Compatible with Laptop & PC Desktop T253X2512G0C101

Ive purchased a total of 16 of these drives. Ive had one fail on me after about 2 months and have not sent it for RMA. Teamgroups RMA procedure on the website says I would need to pay to ship it to Taiwan and pay all customs / duties fees for shipping both ways, but they would pay the return shipping to me. Considering the low cost of the drive and the required amount of time this would take for international shipping, the cost of the international shipping, and the cost of the additional fees I would need to pay, I have waited and I am still debating if I want to deal with that and if its even worth it since Ive been so disappointed with these drives. Ive bought various other items from Teamgroup and so far have been happy with all except these drives and Teamgroups RMA policy. These drives worked well enough for basic single drive operation in a laptop/desktop as long as there was not any large amounts of data written to the drive. After the small internal cache of the drive is filled, they start to write data at ~15-25 MB/s. This is about 10% the performance of a traditional hard drive and about 5% of the performance of the drive before its internal cache is full. Using them in a RAID setup still cannot offset this poor performance. Even with 16 of these drives in a RAID0, they will still drop write rates to around 150-200 MB/s after the cache fills and will typically drop even lower to around 30-50 MB/s for large files (~5GB+). In comparison, a single 8TB traditional hard drive can sustain 180-220 MB/s for the entire file copy. For example, to copy 6.32TB of data over a 10Gb LAN from NVME drives, it took ~35hrs with these drives in a 16 drive RAID0 setup and ~10hrs to copy the same data to a single 8TB traditional hard drive. This is an average rate of ~180 MB/s for the 8TB HDD and ~53 MB/s for 16 of these drives in a RAID0. Setting these drives in other RAID setups was even worse: JBOD (spanned) = ~17 MB/s; RAID5 = ~29 MB/s; RAID6 = ~27 MB/s; RAID10 = ~32 MB/s. While the write speeds are very annoying if planning to write large amounts of data to these drives, it is the read speeds for large amounts of data that is why I am so disappointed. These drives could burst data at high rates and using synthetic benchmarks show very good read speeds in a 16 drive RAID0 setup, but under actual usage, they cannot maintain those speeds for very long and drop to very slow rates as well. The drop in read speeds isnt as significant as the write rates, but it is still an issue. Reading the same 6.32TB of data that was used in my write tests, these drives would average ~220 MB/s. This is much better than the write average, but still only slightly better than a single traditional HDD. Even short bursts are about the same speed when tested using random files. The synthetic benchmarks show read speeds of 4-5 GB/s, but it appears thats because the test file used in these benchmarks easily fit into the drives cache and is read from there during the benchmark tests. However, when testing using random files from the array, the read rate is much slower and mostly in the ~180-250 MB/s range. In summary, if you are looking for an affordable SSD for use in a laptop/desktop or as a boot drive for a server, these drives should be fine, but if you are looking to use these for a NAS or a server, keep looking and avoid these drives. I will note that some of my tests were done using only 15 of these drives in the various RAID setups as one of them failed. I also no longer use these drives and they are just sitting around. My use for these drives was at first for main NAS storage and that was downgraded to use as a backup for my main NAS and now nothing, because using two traditional HDDs in RAID1 for backup is faster than using 15 of these, even if used in RAID0 with no redundancy.

Replacement for failed laptop HD, works very well, no issues,

I liked it because it works well and is durable I clone it to my other hard drive it it worked perfectly

Ya llevo usandolo mas de un año, y ha funcionado perfecto en mi portatil ASUS

The price on SSDs have dropped but this 1T drive is only slightly less than a 2T mechanical drive. No problems migrating my boot disk to this drive with the appropriate software.

Dell Inspiron series 3000 - upgraded to SSD. Cut my boot time from over 3 mins to less than 30 seconds.

I upgrade old laptops with extra RAM + a NEW SSD and sell them sometimes - These SSDs are outperforming western Digital BLUE drives, so I will use Teamgroup instead of Western Digital from now on .. notable speed increase and reliability, no bad errors in windows. all smooth and going well to date. True of 256GB and 512G I have not bought anything bigger.

Good SSD would buy again

Ive done a bit of heavy reading and writing to this drive and it maintains a high speed throughout a heavy write op of many GB of data and thats all I care about, that and maintaining a excellent read speed while reading say 500GB of data from the drive and it does that just fine. I dont know how it will hold up over time because I havent used it enough yet but so far so good. FANTASTIC value for what I paid which was under $100 USD. If you can find these under $110 its a good deal. Prices fluctuate of course because of market forces and this seems to happen more so with memory and storage devices, so dont expect prices to always get lower just because its an older model. If its under $110 its a good price for this quality. It it were a top end SATA SSD it would be more like $130 - $140 and be a good deal.

Muy bien producto.. falta el protector de disco
