Very good price for a high capacity 4TB SSD using TLC memory, even cheaper than what people were paying from Amazon UK during Prime Day. Currently priced at $498 from Shopping Express and $490 on Amazon.
Specs:
Interface - SATA (6Gb/s)
Sequential Read - 560 MB/s
Sequential Write - 510 MB/s
SSD Endurance (TBW) - 1000TB
5 Year warranty
Crucial's MX500 4TB model comes in a 2.5-inch form-factor and continues to rely on Micron's 3D TLC NAND memory, reports HardwareLuxx. Just like lower-capacity SKUs, the 4TB SSD is rated for up to 560 MB/s sequential read speed, up to 510 MB/s sequential write speed as well as up to 90,000 random read/write IOPS. It is unclear whether the Crucial MX500 4TB drive still relies on Silicon Motion's SM2258 controller, but it is quite likely since switching a controller in a family that is four years old does not make a lot of sense (unless it saves quite a lot of money).
As for endurance, the SSD comes with a five-year warranty and is rated for 1,000 terabytes to be written (TBW), which translates to around 0.13 drive writes per day (DWPD), or around 520GB per day. While 0.13 DWPD is rather low, it should be noted that SATA SSDs these days are not really used for write-intensive workloads in desktop environments. Still, those who need to (re)write a lot of data often should probably think twice before getting this 4TB SSD. Souce: https://www.tomshardware.com/news/crucial-adds-4tb-sku-to-mx…
I would say decent, but not very good price.
