Samsung 990 Pro 1TB M.2 NVMe Internal SSD

This SSD shipped with a firmware bug that results in significant performance and lifetime degradation from normal usage - the firmware update 1B2QJXD7 (or newer) needs to be installed manually from Samsung's website, which prevents further deterioration but does not restore SSD performance.

I've had this SSD for several months and with <2TB written, SMART data already shows 6% lifetime usage. For reference, a several-year-old 970 drive with 25TB written shows only 2% usage. Boot times and subjective performance were excellent for the first few weeks but now seem no better than the OEM 980 Pro this replaced.

The Samsung 990 Pro series belong to the fastest SSDs on the market and especially with this 4TB version one gets a very good 2400 TBW durability. Samsung used TLC NAND (three bits per cell) in this model, which is not quite as good as the MLC NAND (2 bit per cell) but it appears no one offers any MLC NAND SSDs anymore. The five year warranty underlines how reliable this drive was designed to be.

If you use this as a boot drive, make sure Windows does not short change you on the capacity since the Windows installer will per default use an MBR (rather than GPT) partition table, causing the drive to only offer 2TB of space, i.e., you'll lose ...view more The Samsung 990 Pro series belong to the fastest SSDs on the market and especially with this 4TB version one gets a very good 2400 TBW durability.

If you use this as a boot drive, make sure Windows does not short change you on the capacity since the Windows installer will per default use an MBR (rather than GPT) partition table, causing the drive to only offer 2TB of space, i.e., you'll lose half the capacity.

Also make sure that the firmware of your 990 PRO is not the 0B2QJXD7 version, as this one had a bug that caused premature wear. Use the Samsung Magician software to check the firmware version and update it, if necessary.

My drive suffered from rapid health loss and then it became corrupted, RMA sent to Samsung as Samsung is asking for drives to be returned if they have rapid health loss so they can investigate My drive suffered from rapid health loss and then it became corrupted, RMA sent to Samsung as Samsung is asking for drives to be returned if they have rapid health loss so they can investigate

I jumped from a 500gb 960 Evo to this 1Tb 990 Evo! the increase in performance is amazing! much faster system load times across the board and the two games I installed on this drive particularly!
If you need to replace something older than a 980 or similar or SATA SSD - and need high performance this is the M.2 SSD for you.

Recently purchased the Samsung 990 during the King's Birthday Weekend sale.

Great SSD with great speeds and an even better deal than the source.

This was cheaper than what was being offered by Samsung as part of their "External Partners" program.

Fast NVME and an easy install Fast NVME and an easy install

I bought another one of these SSDs to install into my laptop. The extra storage has been really good, with fast transfer speeds. Installation was pretty straightforward.
