SATA comes in handy if you are tight on budget and need more storage, SAS benefits you if you need faster storage under 2TB, and NVMe helps you with your high-end storage requirements providing minimum latency. Unless Fibre Channel comes out with a low-cost alternative to its present set of drives, it is likely to lose out as a drive connection in the long run. There will always be a lot to consider when you choose storage components. For disk drives on the SAN, SAS will likely win, but the SAN connection will continue to be Fibre where it is presently Fibre. For connectivity to SANs, Fibre Channel will continue to lead, but iSCSI will pick up momentum.ĥ. For near-line storage, “best in class” will lose out to “good enough.” SATA wins.Ĥ. For servers, both direct-attach and inside-the-box drives will be SAS.ģ. If you buy a SAS box to put them in, you can play mix-and-match with SAS and SATA drives to your heart’s content.įor the long run, as I gaze into my crystal fishbowl, here is what I see:Ģ. The appeal of this will increase if the idea of tiered storage has value for you (if you are considering the benefits of information lifecycle management, this should be the case).Īs for SAS and SATA, when choosing between them follow this rule:Ĭhoose SATA when cost is the most important issue choose SAS whenever data availability and performance count. If you are looking for more flexibility however, then the SAS-SATA interchangeability is likely to be more appealing. If you are a happy Fibre Channel user, and don’t mind paying the slight price differential, you are likely to continue using it. The choice between Fibre Channel and SAS is at present a tough one, as performance is going to be pretty much the same on both platforms for the near future. * SAS drives are faster, and offer several features not available on SATA, including variable sector sizes, LED indicators, dual ports and data integrity. * SAS drives are tested against much more rigid specifications than are SATA drives, and have a significantly longer mean time between failures and duty cycle. * While both types of drives plug into the SAS backplane, a SATA backplane cannot accommodate SAS drives. * SAS drives have dual porting capability, faster spindle speeds and lower latencies. Major differences between the two technologies are: * Both are long-proven technologies, with worldwide acceptance. Please note: Firmware repair for SAS drives and USB flash drives is not supported for the moment.Īny question is welcome to or add Dolphin Skype ID: dolphin.data.* The drives are interchangeable within a SAS drive bay module. Dolphin SAS to SATA adapter works with SATA data recovery equipment to image SAS hard drives or extract lost data from SAS hard drives.ĭolphin Data Lab has one good combination of data recovery equipment and adapters to recover lost data from SATA hard drives, SAS hard drives, SSDs, USB drives, etc.ĭFL-SRP USB3.0 all-in-one data recovery equipmentĭFL-URE Plus Portable data recovery equipment Most available data recovery equipment in the market are for SATA hard drives and few are for SAS hard drive data recovery. SAS and SATA hard drives have different physical interfaces and firmware structures. SAS hard drive data recovery is not that common but it will be more competitive if users can offer SAS hard drive data recovery services. SATA hard drive data recovery has been the most common data recovery cases within data recovery labs worldwide.
