1TB 660p drops as low as 15-30mb/s

Hi,

In the last few weeks I noticed my system feels "stalled" from time to time, when opening the taskmanager I saw my 660p is at 100% writing about ~30mb/s - even with the system is only lightly loaded (browsing the web, developing with visual studio). so only very little write workload and a lot of idle time. same when running linux, no anti-virus used on windows. Trimming ("Optimize") did not help at all. Clearing the cache with the solidigm utility also didn't help.

To diagnose the issue, I ran crystaldiskmark in sequential mode, and while I see some spikes up to 700mb/s, the drive quickly drops to 100mbs/ then to 30mb/s and after while jumps between 15mb/s and 30mb/s.

SMART data is fine, the drive does not overheat (< 55°C) and has about 20% free space in the middle of the drive (first partition from 0-500GB with 200GB free, second partition from 500GB-1TB completly full). Firmware is latest one 5C.

I did expect the 660p to perform extremly poor in write-intensive tasks, but never thought it would slow down a system mostly used for very light workloads. Any ideas what could be the problem here?
Could it be a problem that the free space is located in the middle of the drive instead of at the end?

Dear linuxhippy,

Thank you for reaching out to Solidigm. We are sorry to hear you are experiencing issues with your drive. Could you kindly perform the following steps:

Drive Optimization:

Confirm the drive is using the optimal connection;
Drives under test should be connected to the system as a secondary (non OS) drive;
Make sure the latest Firmware and driver are installed (we can see your drive is on the latest firmware version)
Run secure erase (Important Note: Always back up data regularly and before proceeding as this process removes all data from the drive.)
1. Download & install Solidigm™ Storage Tool and select “Secure Erase” if it’s a NVMe Solidigm™ client SSD;
2. Use some 3^rd party tool like HDAT2* & KillDisk* to perform secure erase on a SATA Solidigm™ client SSD;
Run “Performance Booster”

After having followed the above-mentioned steps, perform the benchmark process using CrystalDiskMark with the following steps:
1. Choose correct SSD type under “Setting” menu
2. Choose “Peak Performance” in “Profile” menu
3. Select the partition/drive needs to be tested
4. Save the results in a text file. This will show the MB/s and the corresponding IOPS results

If you continue to experience any issues with your drive, please contact us via the following link to create a case and we will reach out to you shortly.  https://support.solidigm.com/en-US/anonymous-createcase/
