This review is from: SAMSUNG 845DC EVO MZ-7GE960EW 2.5" 960GB SATA III MLC Enterprise Solid State Drive
Pros: Fast drives, none DOA, price when compared to other enterprise/server SSD's, works with existing SAS/SATA controller in server.
Cons: Lower rated write endurance than some other drives. Took off an egg for this, but time will tell if it was even a factor.
Other Thoughts: Installed 6 of these (from another vendor) in a server with an LSI 9260-8i controller card with FastPath enabled. Set up a RAID 10 array and started restoring data from Veeam backups of our vSphere environment. Booted up restored VM's and everything has been running smoothly for the past few weeks.
Here's a basic rundown of some performance metrics from running SQLIO using a 1 GB test data file and taking an average of 8, 64, 128, and 256 kb block sizes on the system before (with 8 x 450 GB 10k SAS drives) and after:
5,762 IOPS - 280.84 MB/Sec - Max Lat 292 - Avg Lat 4
978 IOPS - 65.83 MB/Sec - Max Lat 969 - Avg Lat 21
2,856 IOPS - 191.93 MB/Sec - Max Lat 204 - Avg Lat 7
1,200 IOPS - 56.93 MB/Sec - Max Lat 554 - Avg Lat 26
20,461 IOPS - 1,013.29 MB/Sec - Max Lat 43 - Avg Lat 1
20,425 IOPS - 997.28 MB/Sec - Max Lat 54 - Avg Lat 1
19,630 IOPS - 978.27 MB/Sec - Max Lat 25 - Avg Lat 1
21,087 IOPS - 989.78 MB/Sec - Max Lat 12 - Avg Lat 1
So, much improved performance (MB/s), much more consistent latency, theoretically lower energy consumption, and no spinning disk! In the random tests, getting a 1,400% to 1,600% increase in speed is amazing!
We'll see how these hold up long term, but we like the results so far. I think the cost over 15k SAS drives (not an option in this case as we needed in excess of 450 GB drives and 2.5" form factor) would be marginal.
If you are looking at buying a server and need internal storage, or have a NAS or SAN device that supports SATA 2.5" drives, you should really look at these as a viable alternative to 10-15k SAS drives. Just remember, you should test workload before buying SSD's. If you have high % or size load in writes, you will be better served by looking at another SSD like the 845DC PRO to meet your needs.
Only downside we have noticed is that the users connected to this server quickly adjusted to the new speed as "normal" and no longer perceive a speed difference. I, however, notice that I can reboot a WS2008R2 machine in about 30 seconds. That's pretty impressive to me considering it was about 2.5 minutes before.
Pros: Compatible with server that it was intended for, price is competitive, works without any errors so far
Cons: Had to shut down server to install, but that isn't really any fault of the RAM.
Other Thoughts: Ordered two of these to expand the RAM in a server running vSphere. When they arrived, one stick had a nice heat sink installed. The other was a bare stick. Product and part numbers on the sticks were exactly the same. My guess is that somewhere along the way, the manufacturer decided to make these less expensive by no longer including the heat sink and I just happened to get one stick from each version. It hasn't seemed to really affect operating temperatures as this server is running in a room with a dedicating cooling system. Just thought I'd point out the oddity to anyone else looking at ordering this product.
I took away one egg for the inconsistency of heat sink and I think the price could be better for RAM with these specs. It is server RAM, so I know it is supposed to be of higher quality, but still, I think Newegg could do a little better.
This review is from: APEVIA TFX-AP300W 300W ATX12V Power Supply
Pros: Fair price, fair cable length, quiet, and came with a power cord.
Other Thoughts: Bought this to replace the failed PSU in a Dell Vostro 200 series SFF computer. Seems to work just fine for this use. 4-pin power for motherboard was a bit of a stretch to reach the connector on the motherboard, but not extreme or worrisome.
I like the black painted metal of this PSU vs the original grey...but it's not like anyone seems this ever again anyway.
Only time will tell as far as reliability goes.
