SSD vs SAS in a server
Posted on 2014-08-31
First, as usual, my question is five times longer than necessary. Sorry. I guess I could have said SSDs vs HDDs on a server.
Well, I wrote an entire question, saved it, and now it is gone. I guess I likely didn't save it. Anyway, I would like advice from the experts as it is time to upgrade my server.
A year ago I purchased eight OCZ SSDs for all of my clients. 6Gbs. Like advertised, they had blazing speed. Of course, you can't talk about an SSD without mentioning the 14 second bootup time, which it provided. But, more importantly, Word would open instantly, My apps just appeared. It was definitely faster. I wouldn't even be writing this question had I purchased Intel or Samsung or even Crucial. I don't know why, but within two weeks three of the eight failed.
Anyway, moving on, all of my clients now have Samsung EVOs, which now have 10-year warranties. My question, obviously, is while I can take a hit on a client, I can't have my server going down out of the blue. Even in the past year, they seem more reliable.
I am on a message board for physicians and one of the users has a large computer, server and networking business. He is Microsoft-certified, etc. He has been pushing RAID 10 (not that that matters, I guess) with four Samsungs. He either uses Lenovos, Dell or custom builds them.
At least 10 physicians have gone that direction. But, I am not sure if they are reliable enough. I feel like I am comining in during the middle of the game, i.e. getting past plain HDDs but maybe SSDs that are not ready for prime time. I would hate to get a Dell that could have used SSDs and have to live with that for four or five years vs. walking in every morning wondering if it is going to running.
So, to sum it up, I am asking for opinions as to what you would do or what you are recommending to your clients. How much faster are SSDs when compared with a WD Red SAS 15K drive? My RAID 1 and RAID 5 consisting of seven drives have performed flawlewssly.
Thanks. And, I am very sorry for the length of the question.
